Microbial systems appear to exhibit a relatively high switching capacity of moving back and forth among few dominant communities (taxon memberships). While this switching behavior has been mainly attributed to random environmental factors, it remains unclear the extent to which internal community dynamics affect the switching capacity of microbial systems. Here, we integrate ecological theory and empirical data to demonstrate that structured community transitions increase the dependency of future communities on the current taxon membership, enhancing the switching capacity of microbial systems. Following a structuralist approach, we propose that each community is feasible within a unique domain in environmental parameter space. Then, structured transitions between any two communities can happen with probability proportional to the size of their feasibility domains and inversely proportional to their distance in environmental parameter space-which can be treated as a special case of the gravity model. We detect two broad classes of systems with structured transitions: one class where switching capacity is high across a wide range of community sizes and another class where switching capacity is high only inside a narrow size range. We corroborate our theory using temporal data of gut and oral microbiota (belonging to class 1) as well as vaginal and ocean microbiota (belonging to class 2). These results reveal that the topology of feasibility domains in environmental parameter space is a relevant property to understand the changing behavior of microbial systems. This knowledge can be potentially used to understand the relevant community size at which internal dynamics can be operating in microbial systems., Competing Interests: Competing interests statement:The authors declare no competing interest.

The southwest alpine canyon area is a typical ecologically fragile area. Understanding the characteristics of vegetation change here and its influencing factors can provide a theoretical basis for formulating countermeasures for ecological environment construction in the southwest alpine canyon area and has practical significance for realizing the harmonious and unified development of the regional economy, environment, and ecology. Based on the data set of NDVI, socio-economic factors, and natural factors from 2000 to 2019, the spatial and temporal variation and stability characteristics of NDVI in the southwest alpine canyon area were analyzed by using the methods of unary linear regression, Hurst index, geographic detector model, and coefficient of variation, and the influencing factors of the spatial differentiation of NDVI were also discussed. The results showed that:① in terms of spatial distribution, the vegetation was high in the southeast and low in the northwest. The area covered by medium and high vegetation accounted for 71.71%, and the vegetation cover was at a relatively high level. From the perspective of time, the area of vegetation showing an improvement trend accounted for 85.90%, and the recovery effect was obvious, and the future vegetation change trend will continue to be improved. ② Elevation, vegetation type, and soil type were the main factors affecting the spatial differentiation of NDVI, and the q value was no less than 0.40. Temperature and rainfall were secondary factors, with q values of 0.274 and 0.225, respectively. The dual-factor interaction enhanced the single factor influence, which was manifested as the dual-factor enhancement and nonlinear enhancement relationship. The highest q value was 0.714 for the combination of altitude ∩ vegetation, followed by 0.688 for the combination of altitude ∩ soil. ③ The overall stability of NDVI during the study period was good, and the proportion of the regional area with low fluctuating changes and slightly low fluctuating changes was 89.95%. The area with moderate fluctuation accounted for 10.05%, concentrated in the relatively fragile ecological environment with factors such as high altitude, low temperature, little rainfall, barren soil, and sparse vegetation. Vegetation change is the result of a combination of multiple factors, so it is necessary to adapt to local conditions and adopt different strategies to restore the ecological environment of the southwest alpine canyon area.

Environmental risk perception has a long-time travel in the public participation in environmental fields. This perception involves individually socially constructed physical and mental experiences that involve many factors just for knowledge, attitudes, and the culture that develops in society. An individual's understanding of environmental risk provides an overview of an individual's preparedness for appropriate environmental risk strategies and measures. This cross-sectional survey study aims to collect data on the environmental risk perception of Indonesian students. The survey data instrument used in this study is the environmental risk perception scale (ERPS) questionnaire, transformed into Google Forms in the Indonesian language. The target respondents were 1,267 students from 1,300 undergraduate population size of educational study programs in the field of biology who came from various institutions in Indonesia. Sexual category, grade point average (GPA), and university status to explore the perception of the active student environment of prospective biology teachers with various parameters. The results showed several interesting findings: the female sex is more sensitive to environmental risks, academic abilities play a more logical role in environmental risk analysis, and respondents who have taken environmental courses have a higher sensitivity to environmental risk.

Groups of animals inhabit vastly different sensory worlds, or umwelten, which shape fundamental aspects of their behaviour. Yet the sensory ecology of species is rarely incorporated into the emerging field of collective behaviour, which studies the movements, population-level behaviours, and emergent properties of animal groups. Here, we review the contributions of sensory ecology and collective behaviour to understanding how animals move and interact within the context of their social and physical environments. Our goal is to advance and bridge these two areas of inquiry and highlight the potential for their creative integration. To achieve this goal, we organise our review around the following themes: (1) identifying the promise of integrating collective behaviour and sensory ecology; (2) defining and exploring the concept of a 'sensory collective'; (3) considering the potential for sensory collectives to shape the evolution of sensory systems; (4) exploring examples from diverse taxa to illustrate neural circuits involved in sensing and collective behaviour; and (5) suggesting the need for creative conceptual and methodological advances to quantify 'sensescapes'. In the final section, (6) applications to biological conservation, we argue that these topics are timely, given the ongoing anthropogenic changes to sensory stimuli (e.g. via light, sound, and chemical pollution) which are anticipated to impact animal collectives and group-level behaviour and, in turn, ecosystem composition and function. Our synthesis seeks to provide a forward-looking perspective on how sensory ecologists and collective behaviourists can both learn from and inspire one another to advance our understanding of animal behaviour, ecology, adaptation, and evolution., Competing Interests: HW, VS, EH, GG, NB, GF, IC, CG, ND, HR, MH, JH, AS, AM No competing interests declared, (© 2023, Williams, Sridhar, Hurme et al.)

This research purposed to test the accuracy of Machine Learning techniques for learner analytics based on SEEEM factors of secondary education students in Thailand's COVID-19. Research volunteer came from secondary education students in Thailand who invited by researcher. The research questionnaire adapted from Computational Thinking Assessment by Korkmaz et al. (2017), Science Process Skills by Pruekpramool (2014), Environmental Literacy Instrument for Adolescents by EPA (2018), Test of Economic Literacy by Walstad et al. (2013), and Technology and Engineering Literacy Student Questionnaire by NAEP (2018). This research employed the statistics in analysis of Mean and Standard Deviation, and Machine Learning Techniques such as Naïve Bay (NB), Support Vector Machine (SVM), Decision Tree (DT), Random Forest (RF), Logistics Regression (LR), Gradient Boosting (GB), Extreme Gradient Boosting (XGB), and Artificial Neural Network (ANN) with 80% for training and 20% for testing. The results of this research as it shown techniques used in data analytics in this paper may benefit to educators, teachers, or students in Thailand.

This paper examines the Confucian concept of learning, or xue ([character omitted]), from the perspective of ecological humanism. Through a comparative interpretation, this paper attempts to disclose the significance of Confucian xue conceived as a practice of aesthetic appreciation and creativity, emphasizing in particular its function within an eco-centric worldview. The author reviews the relevant concepts of ecological humanism as expressed in the ideas of John Dewey and Thomas Alexander, then applies these as a theoretical framework for interpreting xue and its related concepts and practices as they appear in the Confucian text the Lunyu ([characters omitted] ). It is argued that xue is a process of developing and expressing virtuosity and artistry in the "arts of life," and that its practice was understood as a direct participation in the creative development of nature. The significance of such a concept of learning for contemporary educational philosophy is discussed in conclusion.

Improved and more accessible genome-sequencing approaches have allowed the analysis of large sets of natural yeast isolates. As a consequence, this unprecedented level of description of yeast-genome characteristics and variations in natural environments has provided crucial insights on yeast ecology and evolution. Here, we review some of the most relevant and intriguing aspects of yeast evolution pointed out, thanks to the combination of yeast ecology and genomics, and critically examine the resulting improvement of our knowledge on this field. Only integrated approaches, taking into consideration not only the characteristics of the microbe but also those of the hosting environment, will significantly move forward the exploration of yeast diversity, ecology, and evolution., (Copyright © 2022 The Authors.

At the heart of sustainability is the relationship between humans and the planet. The binary of anthropocentric or ecocentric worldviews appears to be powerful in defining this relationship. Sustainability requires nuanced approaches which go beyond simple binaries, and therefore a dialectic approach which works to synthesise the binaries may be helpful. This paper draws on Maori cultural understandings of fire to trouble the ecocentric versus anthropocentric binary. Maori oral traditions of fire identify the connections between people and the planet and see people as part of fire and fire as part of people. By exploring Maori oral traditions, it is possible to see fire as more than purely an element that contributes to environmental problems and reveals the pedagogical potential of campfires to reignite the relationship between humans and the planet.

Understanding animal movement is essential to elucidate how animals interact, survive, and thrive in a changing world. Recent technological advances in data collection and management have transformed our understanding of animal "movement ecology" (the integrated study of organismal movement), creating a big-data discipline that benefits from rapid, cost-effective generation of large amounts of data on movements of animals in the wild. These high-throughput wildlife tracking systems now allow more thorough investigation of variation among individuals and species across space and time, the nature of biological interactions, and behavioral responses to the environment. Movement ecology is rapidly expanding scientific frontiers through large interdisciplinary and collaborative frameworks, providing improved opportunities for conservation and insights into the movements of wild animals, and their causes and consequences.

Large-scale ecological sampling can be difficult and costly, especially for organisms that are too small to be easily identified in a natural environment by eye. Typically, these microscopic floral and fauna are sampled by collecting substrates from nature and then separating organisms from substrates in the laboratory. In many cases, diverse organisms can be identified to the species-level using molecular barcodes. To facilitate large-scale ecological sampling of microscopic organisms, we used a geographic data-collection platform for mobile devices called Fulcrum that streamlines the organization of geospatial sampling data, substrate photographs, and environmental data at natural sampling sites. These sampling data are then linked to organism isolation data from the laboratory. Here, we describe the easyFulcrum R package, which can be used to clean, process, and visualize ecological field sampling and isolation data exported from the Fulcrum mobile application. We developed this package for wild nematode sampling, but it can be used with other organisms. The advantages of using Fulcrum combined with easyFulcrum are (1) the elimination of transcription errors by replacing manual data entry and/or spreadsheets with a mobile application, (2) the ability to clean, process, and visualize sampling data using a standardized set of functions in the R software environment, and (3) the ability to join disparate data to each other, including environmental data from the field and the molecularly defined identities of individual specimens isolated from samples., Competing Interests: The authors have declared that no competing interests exist.

Bacillus mycoides is poorly known despite its frequent occurrence in a wide variety of environments. To provide direct insight into its ecology and evolutionary history, a comparative investigation of the species pan-genome and the functional gene categorization of 35 isolates obtained from soil samples from northeastern Poland was performed. The pan-genome of these isolates is composed of 20,175 genes and is characterized by a strong predominance of adaptive genes (∼83%), a significant amount of plasmid genes (∼37%), and a great contribution of prophages and insertion sequences. The pan-genome structure and phylodynamic studies had suggested a wide genomic diversity among the isolates, but no correlation between lineages and the bacillus origin was found. Nevertheless, the two B. mycoides populations, one from Białowieża National Park, the last European natural primeval forest with soil classified as organic, and the second from mineral soil samples taken in a farm in Jasienówka, a place with strong anthropogenic pressure, differ significantly in the frequency of genes encoding proteins enabling bacillus adaptation to specific stress conditions and production of a set of compounds, thus facilitating their colonization of various ecological niches. Furthermore, differences in the prevalence of essential stress sigma factors might be an important trail of this process. Due to these numerous adaptive genes, B. mycoides is able to quickly adapt to changing environmental conditions. IMPORTANCE This research allows deeper understanding of the genetic organization of natural bacterial populations, specifically, Bacillus mycoides, a psychrotrophic member of the Bacillus cereus group that is widely distributed worldwide, especially in areas with continental cold climates. These thorough analyses made it possible to describe, for the first time, the B. mycoides pan-genome, phylogenetic relationship within this species, and the mechanisms behind the species ecology and evolutionary history. Our study indicates a set of functional properties and adaptive genes, in particular, those encoding sigma factors, associated with B. mycoides acclimatization to specific ecological niches and changing environmental conditions.

Ecological research and practice are crucial to understanding and guiding more positive relationships between people and ecosystems. However, ecology as a discipline and the diversity of those who call themselves ecologists have also been shaped and held back by often exclusionary Western approaches to knowing and doing ecology. To overcome these historical constraints and to make ecology inclusive of the diverse peoples inhabiting Earth's varied ecosystems, ecologists must expand their knowledge, both in theory and practice, to incorporate varied perspectives, approaches and interpretations from, with and within the natural environment and across global systems. We outline five shifts that could help to transform academic ecological practice: decolonize your mind; know your histories; decolonize access; decolonize expertise; and practise ethical ecology in inclusive teams. We challenge the discipline to become more inclusive, creative and ethical at a moment when the perils of entrenched thinking have never been clearer., (© 2021. Springer Nature Limited.)

By sharing their world, humans and other animals sustain each other. Their world gets determined over time as generations of animals act in it. Current approaches to psychological science, by contrast, start from the assumption that the world is already determined before an animal's activity. These approaches seem more concerned with uncertainty about the world than with the practical indeterminacies of the world humans and nonhuman animals experience. As human activity is making life increasingly hard for other animals, this preoccupation becomes difficult to accept. This article introduces an ecological approach to psychology to develop a view that centralizes the indeterminacies of a shared world. Specifically, it develops an open-ended notion of "affordances," the possibilities for action offered by the environment. Affordances are processes in which (a) the material world invites individual animals to participate, while (b) participation concurrently continues the material world in a particular way. From this point of view, species codetermine the world together. Several empirical and methodological implications of this view on affordances are explored. The article ends with an explanation of how an ecological perspective brings responsibility for the shared world to the heart of psychological science.

Climate change and global warming have huge impacts on the most fragile ecosystems on Earth. With temperatures rising, most of the tropical glaciers on Earth, found near the Equator, will be gone before the end of the century. These far-removed natural areas are obscure and difficult for students to visit or learn from directly. Educating students in non-traditional, more experience-based settings is crucial for them to better understand current issues the world is facing, like glacial shrinkage, loss of sea ice, and accelerated sea level rise. This study found that virtual reality 360-degree video technology (VR-360), by providing close to real-life experiences and engaging storytelling, has the ability to engage students and provide them with meaningful information and experiences about climate change. In Phase 1 of this study, 65 students reported that VR can be beneficial for educational purposes to learn about global climate change. In Phase 2, with 227 students from around the globe, path analysis supported the need for VR-360 video producers to consider the importance of spatial presence, in the form of possible action and self-location, as critical elements of their videos to encourage people to use VR technology to learn about extreme environments and climate change.

The need for global education is increasing in this global era, and children's literature becomes an essential resource to address this need. However, there is little research on how global perspectives are depicted in children's literature. The current study fills the gap in our understanding by examining contemporary children's picture books that were published in the United States from 2010 to 2016. Findings show that the picture books reflect several important elements of global education. However, there is an imbalance among the topics and genres. Although global awareness through environmental issues was emphasized through informational texts, transnational story lines on how individuals as world citizens connect to the other people around the world were lacking. The findings provide future directions for more diverse topics to support critical global education in this interconnected world.

The COVID-19 pandemic is a man-made disaster, caused by undue interference in the ecological balance and the lives of multiple species. Paradoxically, the contagion has resulted in increased use of technology and digital mediation, as well as enhanced hopes for vaccines and biomedical solutions. It has thereby intensified humans' reliance on the very high-tech economy of cognitive capitalism that caused the problems in the first place. This combination of ambivalent elements in relation to the Fourth Industrial revolution and the Sixth Extinction is the trademark of the posthuman condition. This essay explores this condition further, offering both critical and affirmative propositions for moving forward.

In the last decade, universities worldwide have adopted various measures intended to promote sustainability in higher education and include it in the curriculum. However, although this paradigm shift appears to be contributing to students' acquisition of the knowledge, skills and values necessary to fight for a more sustainable world, serious global crises such as the present SARS-CoV-2 pandemic oblige us to rethink our behaviour and spur us to accelerate the move towards a deep-seated commitment to the environment and people. Therefore, the aims of this study were (a) to explore consumption habits in students at four Spanish universities by analysing their individual ecological footprint (EF); (b) to develop indices of connection with nature and a pro-environmental attitude and to determine relationships between these indices and students' consumption. Among other factors, our results showed that private university students have a higher EF than public university students; that food consumption has the greatest impact on individuals' EF; and that those who consume more sustainably do not show a more pro-environmental attitude or feel a greater connection with nature. Therefore, we conclude that there was no apparent direct relationship between study participants' convictions and their daily behaviour. There is a pressing need in education to demonstrate the connection between our actions and their environmental impact., Competing Interests: The authors declare no conflict of interest.

This article provides an overview of books published on Brazilian environmental history. Among the large variety of environmental themes seen in Brazilian historiography, we selected the authors who in some way identify themselves as explicitly related to the academic environmental history community. Although the emphasis was on authored books, we sought to at least mention the principal edited books produced in the field. With this mapping, we demonstrate the themes and spatial-temporal foci prioritized by environmental historians in their studies on Brazil. Additionally, we sought to show how the gaps still existing in the literature provide promising paths for future expansion of this field.

The persistence of reef building corals is threatened by human-induced environmental change. Maintaining coral reefs into the future requires not only the survival of adults, but also the influx of recruits to promote genetic diversity and retain cover following adult mortality. Few studies examine the linkages among multiple life stages of corals, despite a growing knowledge of carryover effects in other systems. We provide a novel test of coral parental conditioning to ocean acidification (OA) and tracking of offspring for 6 months post-release to better understand parental or developmental priming impacts on the processes of offspring recruitment and growth. Coral planulation was tracked for 3 months following adult exposure to high pCO 2 and offspring from the second month were reciprocally exposed to ambient and high pCO 2 for an additional 6 months. Offspring of parents exposed to high pCO 2 had greater settlement and survivorship immediately following release, retained survivorship benefits during 1 and 6 months of continued exposure, and further displayed growth benefits to at least 1 month post release. Enhanced performance of offspring from parents exposed to high conditions was maintained despite the survivorship in both treatments declining in continued exposure to OA. Conditioning of the adults while they brood their larvae, or developmental acclimation of the larvae inside the adult polyps, may provide a form of hormetic conditioning, or environmental priming that elicits stimulatory effects. Defining mechanisms of positive acclimatization, with potential implications for carry over effects, cross-generational plasticity, and multi-generational plasticity, is critical to better understanding ecological and evolutionary dynamics of corals under regimes of increasing environmental disturbance. Considering environmentally-induced parental or developmental legacies in ecological and evolutionary projections may better account for coral reef response to the chronic stress regimes characteristic of climate change.

By involving the public, citizen science runs against the grain of an idealized science that leaves out the human element, and thus provides new opportunities for ecological research and society. We classify the goals of citizen science in ecology and environment into four broad categories: (1) scientific, (2) participant benefits, (3) community, and (4) policy. Although none of these goals have been well studied, we review the literature showing that these projects are most effective in tracking ecological trends over large swaths of space and time, and discuss the challenges of recruiting, training, retaining, and educating participants, maintaining and disseminating high-quality data, and connecting with the larger community and policy. Biomedical studies, where patients participate in their own treatment in randomized trials, provide an interesting comparison with citizen science in ecology, sharing challenges in recruitment and involvement of nonscientists and ethical conduct of research. Future study will help address the ethical difficulties and enhance ways for citizen science in ecology and the environment to complement scientific discovery, involve and educate the public, and guide policy founded in science and the local community., (© 2020 New York Academy of Sciences.)

We present a case of environmental transformation, in the Romanian Danube Delta, driven by the interplay of state power, technological intervention, geomorphological processes, and local practices. Through the presentation of a cartographic archive (1856-2017), together with participant observation and historical research, we detail the various stages of transformation in the deltaic environment and show the relative interplay of driving forces. We show that each transformation of the Delta is at the same time an imposition from without and an adaptation from within, a move of consolidation of state power and a resistance to being fully incorporated. We show how in the history of this particular environment, the main drivers of change pass from being of a geomorphological nature to being related to the use of state power. We detail three stages in the transformation of the delta, through which the conceptualization of, and interventions in, the environment, go from a borderland to be secured, to a rich exploitation ground, to an ecological marvel to be protected. We argue that this kind of analysis can be particularly relevant for the governance of protected areas., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Epigenetic changes can provide a pathway for organisms to respond to local environmental conditions by influencing gene expression. However, we still know little about the spatial distribution of epigenetic variation in natural systems, how it relates to the distribution of genetic variation and the environmental structure of the landscape, and the processes that generate and maintain it. Studies examining spatial patterns of genetic and epigenetic variation can provide valuable insights into how ecological and population processes contribute to epigenetic divergence across heterogeneous landscapes. Here, we perform a comparative analysis of spatial genetic and epigenetic variation based on 8,459 single nucleotide polymorphisms (SNPs) and 8,580 single methylation variants (SMVs) from eight populations of the Puerto Rican crested anole, Anolis cristatellus, an abundant lizard in the adaptive radiations of anoles on the Greater Antilles that occupies a diverse range of habitats. Using generalized dissimilarity modelling and multiple matrix regression, we found that genome-wide epigenetic differentiation is strongly correlated with environmental divergence, even after controlling for the underlying genetic structure. We also detected significant associations between key environmental variables and 96 SMVs, including 42 located in promoter regions or gene bodies. Our results suggest an environmental basis for population-level epigenetic differentiation in this system and contribute to better understanding how environmental gradients structure epigenetic variation in nature., (© 2019 John Wiley & Sons Ltd.)

The two banana prawns Penaeus merguiensis and P. indicus are arguably the most commercially important species of penaeid prawns in the tropical and sub-tropical Indo-West Pacific region. They are fecund, short-lived, and have a complex life history involving offshore spawning, inshore mangrove-lined nursery grounds, and migrations between the two locations. We have reviewed and assessed published research on: the fisheries and aquaculture; taxonomy and identification; distribution and habitat preferences; growth; mortality; food and feeding; predation, and the importance of the mangrove habitat to banana prawns. We have examined the life history patterns of these two banana prawns and the many environmental and biological factors that affect different life history stages, often resulting in large interannual variations in abundances of adult prawns and commercial catches. We have also reviewed research on the ecosystem relationships involving these prawns, including fishery impacts on the environment and other species caught as bycatch. In reviewing the published information on factors affecting recruitment dynamics and variability, we have sometimes found contrasting and confounding results, suggesting that these factors are not yet fully understood. Therefore, for each aspect of the prawns' biology we have pointed to areas with incomplete or conflicted understanding, which will hopefully guide future research on these extremely valuable prawn species., (© 2020 Elsevier Ltd All rights reserved.)

Viruses infect all forms of life and play critical roles as agents of disease, drivers of biochemical cycles and sources of genetic diversity for their hosts. Our understanding of viral diversity derives primarily from comparisons among host species, precluding insight into how intraspecific variation in host ecology affects viral communities or how predictable viral communities are across populations. Here we test spatial, demographic and environmental hypotheses explaining viral richness and community composition across populations of common vampire bats, which occur in diverse habitats of North, Central and South America. We demonstrate marked variation in viral communities that was not consistently predicted by a null model of declining community similarity with increasing spatial or genetic distances separating populations. We also find no evidence that larger bat colonies host greater viral diversity. Instead, viral diversity follows an elevational gradient, is enriched by juvenile-biased age structure, and declines with local anthropogenic food resources as measured by livestock density. Our results establish the value of linking the modern influx of metagenomic sequence data with comparative ecology, reveal that snapshot views of viral diversity are unlikely to be representative at the species level, and affirm existing ecological theories that link host ecology not only to single pathogen dynamics but also to viral communities., (© 2019 The Authors.

This article reports how Swedish teachers' aims and practices were modified by an ecosystem services development project that introduced insect hotels, bird boxes and planting to ten preschool yards. Teachers' understanding of ecosystem services, human--nature relationships and the impact of these on nature connectedness showed that their conceptualisations of human--nature relationships were shifting and complex, reflecting overlapping ideas about what schoolyard ecosystem services might mean to/for young children and how children's connection with nature might best be supported. The findings suggest creating pockets of urban nature in schoolyards is a useful strategy to unpack some of this complexity through direct experience of ecosystems encouraging interest in, concern for and understanding of our mutuality with nature.

This study investigates children's perceptions of environmental change and their connection to nature in Mexico's Mediterranean region, an area of global ecological significance. We used a convergent mixed methods design to analyze data from 392 fourth through sixth graders from urban, peri-urban, and rural schools. Integrating quantitative and qualitative data, particularly children's drawings and descriptions, provides a comprehensive view of how children relate to nature and perceive environmental changes. The findings showed a high connection to nature among children, regardless of gender or geographical area. Analyzing the drawings and narratives allowed us to identify three groups of children according to their environmental perceptions. One group had a negative or catastrophic perspective on the future of the environment, another group had a positive and hopeful outlook, and a third group lacked awareness of significant environmental changes, indicating varying attitudes among children toward environmental issues. All groups are unaware of key issues such as biodiversity loss and climate change. This study underscores the critical need for environmental education tailored to local contexts, highlighting the importance of fostering a deeper understanding of environmental challenges among the younger generation.

Winter and early spring wind soil erosion have considerable impacts on ecosystems, human well-being and agricultural production in the low precipitation zones of northern China. Little is known about the impact of growing winter rapeseed on ecological cropping systems and the associated economic benefits in the wind erosion area. To explore the winter rapeseed cover effect, we conducted a field experiment in which we covered the soil with winter rapeseed, winter wheat and wheat stubble at different plant density levels and used the spring bare ground as the control (CK). The effects of wind erosion, the "winter rapeseed + " multiple cropping system, and the economic benefits were compared. There was a large difference in the dry matter, the maximum water absorption, the maximum water storage, the soil evaporation and total wind erosion, the amount of sediment transported in the stratum and the wind erosion modulus. Among them, the mean wind erosion modulus of spring sowing bare land was as high as 490.9 kg·hm -2 ·h -1 , which was 7 and 13 times that of winter wheat and winter rapeseed, respectively. As the wind speed increased from 14 to 22 m·s -1 , from a small density to a large density, the mean wind erosion modulus decreased from 68 to 17 kg·hm -2 ·h -1 for winter rapeseed, and 150 to 31 kg·hm -2 ·h -1 for winter wheat. Total wind-erosion of sediment transport of CK was 18.6 g·m -2 min -1 , which was 16 and 31 times the mean value of winter wheat and winter rapeseed, respectively. "Winter rapeseed + " replanting peanuts, potatoes, rice, seed melons and other crops generally increased the production value by 5-74% compared with wheat and corn intercropping, which was 98-255% higher than the traditional wheat single crop. Our results suggested that the suitable area for planting winter rapeseed in northern China was approximately 3.3 × 10 6 hm 2 , and in terms of the best economic and ecological effects, the appropriate density was 5 × 10 5 plants·hm -2 in northern China. Our results indicated that Chinese winter rapeseed was the best choice for preventing wind erosion and improving ecological and economic benefits in winter and spring in northern China; additionally, winter rapeseed has important impacts on agricultural sustainability in semi-arid and arid climates.

Communication between resource users has repeatedly been shown to be of significant importance in environmental management. The proposed causal mechanisms are numerous, ranging from the ability of users to share information to their ability to negotiate solutions to common problems and dilemmas. However, what is less known is under what conditions these potential causal mechanisms are important and if, in cases when different means other than communication were available, whether they would be more effective in accomplishing these objectives. An example of such an alternative could be that instead of (or in addition to) users being reliant on within-group communication to acquire useful information an intermediary-such as a public agency-could provide that for them. Furthermore, the different causal mechanisms making communication beneficial might not be independent, neither in respect to each other, nor in respect to other externally imposed means to facilitate better environmental management, and not in regards to different contextual factors. This study makes use of laboratory experiments in an innovative way to explore these questions and specifically test the relative importance of communication in managing complex social-ecological system characterized by common-pool resource dilemmas, ecological interdependencies, and asymmetric resource access-all characteristics being present simultaneously. We find that when resources users are confronted with such a complex challenge, the ability to communicate significantly increases individual and group performance. What is more surprising is the negative effect on overall outcomes that providing external information has on outcomes, when the users also have the ability to communicate. By analysing the content of the conversations we are able to suggest several possible explanations on how the combination of external information provisioning and user communications act to increase individual cognitive load and drives intra-group competition, leading to a significant reduction of individual and group outcomes., Competing Interests: The authors have declared that no competing interests exist.

Learning that empowers students' environmental literacy needs to be encouraged considering the increasing environmental damage. This study aimed to reflect on educational programs on environmental sustainability by measuring the environmental literacy of high school students and identifying the relationship between environmental literacy domains. This correlational survey research involved 154 students taken by random sampling technique. Data analysis used descriptive statistics, Pearson product-moment correlation test, and multiple regression test. The results of data analysis showed: (1) environmental literacy of high school students was categorized as moderate; (2) the domain of knowledge and cognitive skills was high, while the domain of attitudes and behavior towards the environment was moderate; and (3) the knowledge domain had a significant relationship with the cognitive skill, the attitude had a significant relationship with the behavioral domain, while there was no significant relationship between the knowledge domain and the attitude domain. The findings of this study indicated that the empowerment of environmental literacy through educational institutions was not yet optimal. Therefore, it is necessary to evaluate local and operational-based environmental education policies, such as integrating environmental literacy content with local culture in the learning process.

Individual-based models, 'IBMs', describe naturally the dynamics of interacting organisms or social or financial agents. They are considered too complex for mathematical analysis, but computer simulations of them cannot give the general insights required. Here, we resolve this problem with a general mathematical framework for IBMs containing interactions of an unlimited level of complexity, and derive equations that reliably approximate the effects of space and stochasticity. We provide software, specified in an accessible and intuitive graphical way, so any researcher can obtain analytical and simulation results for any particular IBM without algebraic manipulation. We illustrate the framework with examples from movement ecology, conservation biology, and evolutionary ecology. This framework will provide unprecedented insights into a hitherto intractable panoply of complex models across many scientific fields.

For more than 70 years, Hutchinson's concept of the fundamental niche has guided ecological research. Hutchinson envisioned the niche as a multidimensional hypervolume relating the fitness of an organism to relevant environmental factors. Here, we challenge the utility of the concept to modern ecologists, based on its inability to account for environmental variation and phenotypic plasticity. We have ample evidence that the frequency, duration, and sequence of abiotic stress influence the survivorship and performance of organisms. Recent work shows that organisms also respond to the spatial configuration of abiotic conditions. Spatiotemporal variation of the environment interacts with the genotype to generate a unique phenotype at each life stage. These dynamics cannot be captured adequately by a multidimensional hypervolume. Therefore, we recommend that ecologists abandon the niche as a tool for predicting the persistence of species and embrace mechanistic models of population growth that incorporate spatiotemporal dynamics., (© The Author(s) 2019.

A major goal of evolutionary science is to understand how biological diversity is generated and altered. Despite considerable advances, we still have limited insight into how phenotypic variation arises and is sorted by natural selection. Here we argue that an integrated view, which merges ecology, evolution and developmental biology (eco evo devo) on an equal footing, is needed to understand the multifaceted role of the environment in simultaneously determining the development of the phenotype and the nature of the selective environment, and how organisms in turn affect the environment through eco evo and eco devo feedbacks. To illustrate the usefulness of an integrated eco evo devo perspective, we connect it with the theory of resource polymorphism (i.e. the phenotypic and genetic diversification that occurs in response to variation in available resources). In so doing, we highlight fishes from recently glaciated freshwater systems as exceptionally well-suited model systems for testing predictions of an eco evo devo framework in studies of diversification. Studies on these fishes show that intraspecific diversity can evolve rapidly, and that this process is jointly facilitated by (i) the availability of diverse environments promoting divergent natural selection; (ii) dynamic developmental processes sensitive to environmental and genetic signals; and (iii) eco evo and eco devo feedbacks influencing the selective and developmental environments of the phenotype. We highlight empirical examples and present a conceptual model for the generation of resource polymorphism - emphasizing eco evo devo, and identify current gaps in knowledge., (© 2019 The Authors.

Sonotopes are the acoustic patches of a soundscape, composed by different occurrences of geophonies, biophonies, and technophonies. According an ecosemiotic perspective, ecoacoustic events (EEs) are the vehicles from the attribution of meaning to the emergent sonotopes and work as neural codes. The process of encoding is suggested to be active between the perception of sonotopes and EE detection. In Ortolano Rural Sanctuary, from a grid of 12 acoustic digital recorders (ADRs) at an average distance of 30 m each with a microphone set to receive sounds from a near acoustic field, 824,160 one-minute acoustic files were obtained from October 2017 to September 2018. From these files, using the combination of three acoustic complexity indices (ACI ft , ACI ft evenness, and ACI tf evenness), through the ecoacoustic event detection and identification (EEDI) procedure, more than 200 EEs on average per ADR were extracted during this period. The EEs were seasonally aggregated with a significant separation between fall-winter and spring-summer periods. Rain and wind were important in EE composition according to location and seasonality. The number of EEs detected from just one month to three months was 57% of the total, and the first of the nine classes of ACI ft belonged to 78% of all classes of abundance. The EEs and ACI tf similarity were not correlated with the distance between ADRs, confirming the correctness of the near-field approach to detect sounds from landscapes and EE spatial independence. The ranging capacities to distinguish distance from sound sources and to discriminate the temporal and frequential patterns of acoustic signals are some of the mechanisms that species use to detect and encode environmental acoustic complexity. Species are supposed to use EE to explore and assess the acoustic habitat and probably to obtain mental maps of the surroundings they must move around using an acoustic exploration., (Copyright © 2019.

The drivers of latitudinal differences in the phylogenetic and ecological composition of communities are increasingly studied and understood, but still little is known about the factors underlying morphological differences. High-resolution, three-dimensional morphological data collected using computerized micro-tomography (micro-CT) allows comprehensive comparisons of morphological diversity across latitude. Using marine bivalves as a model system, this study combines 3D shape analysis (based on a new semi-automated procedure for placing landmarks and semilandmarks on shell surfaces) with non-shape traits: centroid size, proportion of shell to soft-tissue volume, and magnitude of shell ornamentation. Analyses conducted on the morphology of 95% of all marine bivalve species from two faunas along the Atlantic coast of North America, the tropical Florida Keys and the boreal Gulf of Maine, show that morphological shifts between these two faunas, and in phylogenetic and ecological subgroups shared between them, occur as changes in total variance with a bounded minimum rather than directional shifts. The dispersion of species in shell-shape morphospace is greater in the Gulf of Maine, which also shows a lower variance in ornamentation and size than the Florida Keys, but the faunas do not differ significantly in the ratio of shell to internal volume. Thus, regional differences conform to hypothesized effects of resource seasonality and predation intensity, but not to carbonate saturation or calcification costs. The overall morphological differences between the regional faunas is largely driven by the loss of ecological functional groups and family-level clades at high latitudes, rather than directional shifts in morphology within the shared groups with latitude. Latitudinal differences in morphology thus represent a complex integration of phylogenetic and ecological factors that are best captured in multivariate analyses across several hierarchical levels., Competing Interests: The authors have declared that no competing interests exist.

Ecological systems are made up of complex and often unknown interactions and feedbacks. Uncovering these interactions and feedbacks among species, ecosystem functions, and ecosystem services is challenging, costly, and time-consuming. Here, we ask: for which ecosystem features does resolving the uncertainty about the feedbacks from ecosystem function to species improve management outcomes? We develop a dynamic value of information analysis for risk-neutral and risk-prone managers on motif ecosystems and explore the influence of five ecological features. We find that learning the feedbacks from ecosystem function to species does not improve management outcomes for maximising biodiversity, yet learning which species benefit from an ecosystem function improves management outcomes for ecosystem services by up to 25% for risk-neutral managers and 231% for risk-prone managers. Our general approach provides useful guidance for managers and researchers on when learning feedbacks from ecosystem function to species can improve management outcomes for multiple conservation objectives.

The dynamics of species' densities depend both on internal and external variables. Internal variables include frequencies of individuals exhibiting different phenotypes or living in different spatial locations. External variables include abiotic factors or non-focal species. These internal or external variables may fluctuate due to stochastic fluctuations in environmental conditions. The interplay between these variables and species densities can determine whether a particular population persists or goes extinct. To understand this interplay, we prove theorems for stochastic persistence and exclusion for stochastic ecological difference equations accounting for internal and external variables. Specifically, we use a stochastic analog of average Lyapunov functions to develop sufficient and necessary conditions for (i) all population densities spending little time at low densities i.e. stochastic persistence, and (ii) population trajectories asymptotically approaching the extinction set with positive probability. For (i) and (ii), respectively, we provide quantitative estimates on the fraction of time that the system is near the extinction set, and the probability of asymptotic extinction as a function of the initial state of the system. Furthermore, in the case of persistence, we provide lower bounds for the expected time to escape neighborhoods of the extinction set. To illustrate the applicability of our results, we analyze stochastic models of evolutionary games, Lotka-Volterra dynamics, trait evolution, and spatially structured disease dynamics. Our analysis of these models demonstrates environmental stochasticity facilitates coexistence of strategies in the hawk-dove game, but inhibits coexistence in the rock-paper-scissors game and a Lotka-Volterra predator-prey model. Furthermore, environmental fluctuations with positive auto-correlations can promote persistence of evolving populations and persistence of diseases in patchy landscapes. While our results help close the gap between the persistence theories for deterministic and stochastic systems, we highlight several challenges for future research.

The relationship between national income growth and the environment of 14 Asian economies over a 50 year period is examined using the Environmental Kuznets Curve (EKC) hypothesis. Ecological Footprint (EF) measures environmental impacts and gross domestic product (GDP) measures economic growth. It is hypothesised that increased rates of economic growth come at a cost to the natural environment. The EKC hypothesis has been mainly tested in the literature by cross-sectional or panel data methods. In this study, it is tested using time series analysis through initially examining the relationship between EF and GDP using linear, quadratic and cubic estimating OLS regression functions. In the second stage, the long-run relationship between EF and GDP is investigated using an augmented error correction trend model. There is a statistically significant cointegrated long-run relationship between the variables in most of the countries. The EKC hypothesis is supported in the case of India, Nepal, Malaysia and Pakistan with the other countries exhibiting a positive linear relationship between the two variables. Almost all error correction terms are correct in sign and significance that implies that some percentage of disequilibria in EF in the previous year adjusts back to the long-run equilibrium in the current year. Based on the long-run relationship, it is apparent that rapid economic growth has had an impact on the environment and the ecosystems of these countries over the last 50 years. Despite that, until now, not many of them have taken sufficient steps to reduce their EF or to improve their bioproductive capacity.

Researchers of the Northeast Ethics Education Partnership (NEEP) at Brown University sought to improve an understanding of the ethical challenges of field researchers with place-based communities in environmental studies/sciences and environmental health by disseminating a questionnaire which requested information about their ethical approaches to these researched communities. NEEP faculty sought to gain actual field guidance to improve research ethics and cultural competence training for graduate students and faculty in environmental sciences/studies. Some aspects of the ethical challenges in field studies are not well-covered in the literature. More training and information resources are needed on the bioethical challenges in environmental field research relating to maximizing benefits/reducing risks to local inhabitants and ecosystems from research; appropriate and effective group consent and individual consent processes for many diverse communities in the United States and abroad; and justice considerations of ensuring fair benefits and protections against exploitation through community-based approaches, and cultural appropriateness and competence in researcher relationships.

Plant phenotypes are the result of both genetic and environmental forces that act to modulate trait expression. Over the last few years, numerous approaches in functional genomics and systems biology have led to a greater understanding of plant phenotypic variation and plant responses to the environment. These approaches, and the questions that they can address, have been loosely termed evolutionary and ecological functional genomics (EEFG), and have been providing key insights on how plants adapt and evolve. In particular, by bringing these studies from the laboratory to the field, EEFG studies allow us to gain greater knowledge of how plants function in their natural contexts., (© 2018 The Authors The Plant Journal © 2018 John Wiley & Sons Ltd.)

Education for Sustainable Development (ESD) is becoming an important part of general education, based on a concept that includes three components: Environmental, Social and Economic. The sustainable development curriculum in Croatia is based on this concept, and activities in this area are mainly limited to environmental protection and ecological activities. At the same time, the technological and political context needed to take the right action and develop critical thinking and a systemic approach is lacking. In this context, a survey on pupils' attitudes towards the relationship between technology and engineering with the themes of ecology and sustainable development was conducted to investigate the impact of this curriculum on students' awareness. The research was conducted on a stratified sample of primary school pupils (N = 2205) from Croatia. The results show that pupils view technology as important for life and progress, but do not understand how it relates to sustainable development and environmental issues. This refers to issues of water conservation, construction of facilities, waste disposal, and understanding technology only as pollution. These results point to the need for "deeper" and transformative technology teaching that takes place in a real-world context. Only in this way can students understand the concept and meaning of sustainable development and the role and importance of technology in this context, and be educated to be responsible citizens.

It has been suggested that traditional ecological knowledge (TEK) may play a key role in forest conservation. However, empirical studies assessing to what extent TEK is associated with forest conservation compared with other variables are rare. Furthermore, to our knowledge, the spatial overlap of TEK and forest conservation has not been evaluated at fine scales. In this paper, we address both issues through a case study with Tsimane' Amerindians in the Bolivian Amazon. We sampled 624 households across 59 villages to estimate TEK and used remote sensing data to assess forest conservation. We ran statistical and spatial analyses to evaluate whether TEK was associated and spatially overlapped with forest conservation at the village level. We find that Tsimane' TEK is significantly and positively associated with forest conservation although acculturation variables bear stronger and negative associations with forest conservation. We also find a very significant spatial overlap between levels of Tsimane' TEK and forest conservation. We discuss the potential reasons underpinning our results, which provide insights that may be useful for informing policies in the realms of development, conservation, and climate. We posit that the protection of indigenous cultural systems is vital and urgent to create more effective policies in such realms.

The Biological Resource Centre for the Environment BRC4Env is a network of Biological Resource Centres (BRCs) and collections whose leading objectives are to improve the visibility of genetic and biological resources maintained by its BRCs and collections and to facilitate their use by a large research community, from agriculture research to life sciences and environmental sciences. Its added value relies on sharing skills, harmonizing practices, triggering projects in comparative biology, and ultimately proposing a single-entry portal to facilitate access to documented samples, taking into account the partnership policies of research institutions as well as the legal frame which varies with the biological nature of resources. BRC4Env currently includes three BRCs: the Centre for Soil Genetic Resources of the platform GenoSol, in partnership with the European Conservatory of Soil Samples; the Egg Parasitoids Collection (EP-Coll); and the collection of ichthyological samples, Colisa. BRC4Env is also associated to several biological collections: microbial consortia (entomopathogenic bacteria, freshwater microalgae…), terrestrial arthropods, nematodes (plant parasitic, entomopathogenic, animal parasitic...), and small mammals. The BRCs and collections of BRC4Env are involved in partnership with academic scientists, as well as private companies, in the fields of medicinal mining, biocontrol, sustainable agriculture, and additional sectors. Moreover, the staff of the BRCs is involved in many training courses for students from French licence degree to Ph.D, engineers, as well as ongoing training.

This paper discussed the relationship between language, ecology, and culture, and claimed that the study of linguistic communication as pragmatics should not be confined to the traditional context, but should focus on a broader ecological environment. It analyzed the context of practical communication from the perspective of language ecology beginning with the discussion of the ecological crisis in communication and found that language, like plants and animals in nature, needed the support of the external environment with certain "soil fertility". This paper classified ecological context into two types: internal ecological context (psychological-cognitive context) and external ecological context (natural environment and social environment). Based on this classification, the ecological context of pragmatics was further divided into environment-friendly context, addressee-friendly context, and speaker-friendly ecological context. This paper was an exploratory analysis of language ecology in pragmatics, aiming at helping communicative participants find their ecological niche and adopt appropriate strategies to maintain the ecological balance in pragmatic communication.

This research is conducted to identify the scientific conceptual cognition of ecosystem and the corresponding alternative conceptions by lower-secondary school students in Taiwan. Concept mapping, interviewing, and two-tier diagnostic test cannot make explicit reasoning pathways that students may use. Therefore, its purpose is to develop, validate, and utilize a three-tier multiple-choice diagnostic instrument for the ecosystem concept (TDIEC). The instrument can assist teachers in analyzing their students' reasoning. This does not only distinguish alternative conceptions from lack of knowledge but also determines the percentages of false positives and false negatives. One hundred and six students were tested with this instrument in Taiwan. The data analysis reveals common alternative conceptions shared by students, indicating that 35.59% of the samples had inaccurate conceptualizations of ecosystems. Common alternative conceptions of ecosystems include the following: (1) Only biological components constitute an ecosystem; (2) The Venus flytrap and pitcher plants are preys; (3) Competition is synonymous to predation; (4) Ecological balance refers to the sustainable circulation of energy and matter in the environment; and (5) The simpler the species, the more stable the ecosystem. It concludes with the interpretation of the results, suggestions for the application of the TDIEC, and correct alternative conceptions in Ecology classes.

The relevance of circular economy to environmental science has led to a notable increase of research works during the last few years. It is very important to know the evolution of the publications that relate these two concepts, as well as the main areas of knowledge in which these investigations are framed. The purpose is to understand and highlight the state of art of circular economy and the role and relationship of the environment. Bibliometric analysis allows to evaluate developments in knowledge on a specific subject and assesses the scientific influence of researches and sources. This paper analyses the worldwide research dynamics on circular economy in the period from 2006 to 2017. A bibliometric analysis of 743 articles was completed. The most productive journals in this field were Journal of Cleaner Production. The five most productive countries were China, United Kingdom, Italy, the Netherlands, and Germany. Works on the circular economy and environment has considerable potential and it is open to research fields as sustainability or industrial production. The findings of this study could prove useful for studies into environmental circular economy, as they show a global sight of this line of study. Thus, the article represents a contribution to identify the main trends in circular economy research and environment and, from there, propose future research initiatives., Competing Interests: The authors declare no conflict of interest.
