Vertical gardens (VG) applies plant growth to various wall media and/or other vertical surfaces. In Banda Aceh City, these urban greening innovations are beginning to create trends as they boost building esthetics. The objectives of this research were to identify the various types of vertical gardens and to analyze people's preferences, including the design and variety of plants used in these types of vertical gardens, between January and September 2022 in nine sub-districts of Banda Aceh City, Aceh Province, Indonesia. The research method involved an exploratory survey of the entire city where VG was applied in various public spaces, private and public organizations, residential housing, hotels, mosques, various business culinary, and cafeterias. Data on garden preferences were collected and analyzed using descriptive methodology, and the Shannon-Wiener Formula was used to examine the species diversity index. From a total of 166 documented gardens and 150 sample locations where vertical gardens were observed, 66 plant species were discovered. Vertical gardens are most frequently used in residential housing. Ficus pumilla (dollar creeper) is the plant most frequently used by the community, and green facades are the most common style of vertical garden design applications. In the nine sub-districts, the highest diversity index was found in the Syiah Kuala Sub-district with H' 2.9, and the lowest diversity index was found in the Kuta Raja subdistrict with H’ 1.2. Based on plant function, there were 43 species of ornamental plants, 13 species of flowering plants, 7 species of fruitful plants, and 3 species of herbs. [ABSTRACT FROM AUTHOR]

The aim of this work was to assess the effectiveness of the treatment process in the mine water treatment plant in Mariánské Radčice that pumps mine water from the MR1 pit and to evaluate whether this biotechnological unit is satisfactory in its treatment process with regard to the set limits for the discharge of treated mine water into watercourses, or whether this water can be discharged into Lake Most in the future, which is intended for recreation, and also with regard to the ecosystem that exists there.

Background and aims: Hyperaccumulator plants exhibit extreme ecophysiological characteristics, which make them suited for phytoremediation. Understanding their ecological strategies might help identify the species and functions to be favored in phytoremediation, restoration, and conservation projects for metalliferous sites. Methods: Here, we identified the hyperaccumulator species in the worldwide plant trait database TRY and cross-referenced these trait syndromes associated with the ability of plants to concentrate metals. This allows us to link trace element hyperaccumulation with broader plant ecological strategies. Results: Hyperaccumulator plant species tend to have smaller leaves and poorer competitive ability compared to non-hyperaccumulator plant species. Contrary to expectations, we found no indication of hyperaccumulator plants being more resource-conservative on the leaf economics spectrum. However, these data remain fragmentary as only 2.7% of hyperaccumulator plant species have their traits published in the TRY database. Conclusion: The recent development of trait-based models to construct plant communities providing optimal ecosystem services (e.g., phytoremediation, restoration) requires further research to identify predictable trait-service relationships. We thus call for an international collaborative sampling effort to measure traits in more hyperaccumulator plant species. [ABSTRACT FROM AUTHOR]

A central paradigm in comparative ecology is that species sort out along a slow-fast resource economy spectrum of plant strategies, but this has been rarely tested for a comprehensive set of stem traits and compartments. We tested how stem traits vary across wood and bark of temperate tree species, whether a slow-fast strategy spectrum exists, and what traits make up this plant strategy spectrum. For 14 temperate tree species, 20 anatomical, chemical, and morphological traits belonging to six key stem functions were measured for three stem compartments (inner wood, outer wood, and bark). The trait variation was explained by major taxa (38%), stem compartments (24%), and species within major taxa (19%). A continuous plant strategy gradient was found across and within taxa, running from hydraulic safe gymnosperms to conductive angiosperms. Both groups showed a second strategy gradient related to chemical defense. Gymnosperms strongly converged in their trait strategies because of their uniform tracheids. Angiosperms strongly diverged because of their different vessel arrangement and tissue types. The bark had higher concentrations of nutrients and phenolics whereas the wood had stronger physical defense. The gymnosperms have a conservative strategy associated with strong hydraulic safety and physical defense, and a narrow, specialized range of trait values, which allow them to grow well in drier and unproductive habitats. The angiosperm species show a wider trait variation in all stem compartments, which makes them successful in marginal- and in mesic, productive habitats. The associations between multiple wood and bark traits collectively define a slow-fast stem strategy spectrum as is seen also for each stem compartment. [ABSTRACT FROM AUTHOR]

Summary: The effects of plants on the biosphere, atmosphere and geosphere are key determinants of terrestrial ecosystem functioning. However, despite substantial progress made regarding plant belowground components, we are still only beginning to explore the complex relationships between root traits and functions. Drawing on the literature in plant physiology, ecophysiology, ecology, agronomy and soil science, we reviewed 24 aspects of plant and ecosystem functioning and their relationships with a number of root system traits, including aspects of architecture, physiology, morphology, anatomy, chemistry, biomechanics and biotic interactions. Based on this assessment, we critically evaluated the current strengths and gaps in our knowledge, and identify future research challenges in the field of root ecology. Most importantly, we found that belowground traits with the broadest importance in plant and ecosystem functioning are not those most commonly measured. Also, the estimation of trait relative importance for functioning requires us to consider a more comprehensive range of functionally relevant traits from a diverse range of species, across environments and over time series. We also advocate that establishing causal hierarchical links among root traits will provide a hypothesis‐based framework to identify the most parsimonious sets of traits with the strongest links on functions, and to link genotypes to plant and ecosystem functioning.

Summary: Plant stoichiometric coupling among all elements is fundamental to maintaining growth‐related ecosystem functions. However, our understanding of nutrient balance in response to global changes remains greatly limited to plant carbon : nitrogen : phosphorus (C : N : P) coupling.Here we evaluated nine element stoichiometric variations with one meta‐analysis of 112 global change experiments conducted across global terrestrial ecosystems and one synthesis over 1900 species observations along natural environment gradients across China.We found that experimentally increased soil N and P respectively enhanced plant N : potassium (K), N : calcium (Ca) and N : magnesium (Mg), and P : K, P : Ca and P : Mg, and natural increases in soil N and P resulted in qualitatively similar responses. The ratios of N and P to base cations decreased both under experimental warming and with naturally increasing temperature. With decreasing precipitation, these ratios increased in experiments but decreased under natural environments. Based on these results, we propose a new stoichiometric framework in which all plant element contents and their coupling are not only affected by soil nutrient availability, but also by plant nutrient demand to maintain diverse functions under climate change.This study offers new insights into understanding plant stoichiometric variations across a full set of mineral elements under global changes.
