Abstract

The missionaries of the Society of Jesus emerged as significant social and political agents in the Colony, allowing the presence of the crown to be felt. As these men took on the responsibility for the health care of the colony's inhabitants, this enabled the Order to build a significant body of knowledge, the restricted circulation of which among its members conferred political importance upon them in the Portuguese Court. Communication, in this context, is positioned as a tool for gathering power in the face of situations experienced by the missionaries, due to its political dimension. Lastly, we seek to highlight the role of the circulation of missionary knowledge in the process of power configuration in the colonial world. [ABSTRACT FROM AUTHOR]

Abstract

The influence of bleeding on color, texture profile, and chemical quality of frozen pirarucu loins were investigated. The loins were obtained from eighteen (n=18) pirarucu carcasses from animals slaughtered by bleeding (BLE; n = 9) or without bleeding (NON-BLE; n = 9). The loins were sliced and assigned randomly for 1 and 12 months at -20ºC to analyze pH, water holding capacity, instrumental color, and texture profile BLE samples exhibited higher L* values (P < 0.05), whereas BLE and NON-BLE exhibited similar (P > 0.05) pH, a* values, b* values, and color stability at months 1 and 12. NON-BLE samples demonstrated greater (P < 0.05) hardness and chewiness at month 1, whereas similar (P > 0.05) springiness and cohesiveness were observed in BLE and NON-BLE samples at months 1 and 12. During storage, Both samples (BLE and NON-BLE) demonstrated a decrease (P < 0.05) in pH and water holding capacity; and an increase (P < 0.05) in lightness, hardness, and chewiness. Also, BLE and NON-BLE exhibited stable (P > 0.05) redness, yellowness, color stability, and cohesiveness. NON-BLE samples exhibited a decrease (P < 0.05) in springiness from the 1st to the 12th month of frozen storage. Bleeding positively influenced the quality of frozen pirarucu.

34. Understanding Multidirectional Climate Change Impacts on Local Livelihoods through the Lens of Local Ecological Knowledge: A Study in Western Amazonia.

Abstract

Climate-related changes taking place in Amazonia substantially impact social-ecological systems, affecting local livelihoods strongly reliant on natural resources. Here, we investigate climate change impacts on different livelihood activities in western Amazonia, through the lens of local ecological knowledge. We conducted semi-structured interviews and surveys with ∼400 residents from 24 communities spread across a ∼600 km stretch of the Juruá River. Residents reported a vast set of changes, many referring to changes in the atmospheric system (e.g., more summer rainfall), but with cascading effects in physical, biological, and human systems. Different livelihood activities are impacted with different intensities and by different climate-related changes. While most changes have negative impacts, residents recognize some positive impacts of climate-driven changes (e.g., large river floods positively impact fishing). Beyond demonstrating the manifold and multidirectional climate change impacts, our findings highlight the contribution of local ecological knowledge in identifying vulnerable livelihood activities and biodiversity-based value chains.

42. Involving local communities for effective citizen science: determining game species' reproductive status to assess hunting effects in tropical forests

Abstract

1. Involving communities in sustainable wildlife management in tropical forests can ensure food security and livelihoods of millions of forest dwellers that depend on wild meat, but also safeguard hunted species. Mathematical models have been developed to assess hunting sustainability; but these require empirical information on reproductive parameters of the prey species, often challenging to obtain. 2. Here, we suggest that if local people can accurately identify the reproductive status of hunted animals in the field, these data could fill the existing knowledge gap regarding species’ life-history traits and enable better assessments of hunting impacts. 3. We first tested whether local people in 15 rural communities in three Amazonian sites could accurately diagnose, before and after training, the pregnancy status of hunted pacas (Cuniculus paca), which we use as our model. We then applied the results from these tests to correct reproductive status data of hunted specimens, voluntarily collected over 17 years (2002-2018) as part of a citizen science project in one of our study sites. We ran generalized additive models to contrast these corrected reproductive rates with those obtained from the direct analysis of genitalia by researchers, and with indices describing game extraction levels (catch-per-unit-effort, CPUE, and age structure of hunted individuals). 4. Before training, interviewees correctly diagnosed pregnancy in 72.5% of tests, but after training, interviewees accurately diagnosed pregnancy in 88.2% of tests, with high improvements especially for earlier pregnancy stages. Monthly pregnancy rates determined by hunters and by researchers were similar. Reported annual pregnancy Page 3 of 45 Confidential Review copy Journal of Applied Ecology 4 rates were negatively correlated with CPUE, and positively correlated with the percentage of immatures in the hunted population, in accordance to an expected densitydependent response to variations in hunting levels. 5

Abstract

Climate change is expected to significantly change the availability and trade of fishery products due to changes in the distribution and productivity of marine and freshwater species. However, the high diversity in aquatic systems and their associated fisheries result in a mosaic of impacts and responses at the local scale which have not been comprehensively documented yet. This protocol has been designed to collect standardised local level data of local fishery changes and resulting adaptations of fishing communities around the world.

47. Community-Based Management of Amazonian Biodiversity Assets

Abstract

The Amazon is the largest forest system on Earth, supporting a variety of indigenous societies, small farmers, extractivists, and artisanal fishers with different cultures and relations with wildlife. However, the Brazilian Amazon has lost more than 436, 000 km2 of forest in the last 30 years, and Protected Areas may not be enough to ensure the conservation of biodiversity and cultural heritage. On the other hand, formal alliances with rural inhabitants can decentralize resource management, strengthen full-time surveillance systems, reduce overall costs, and boost conservation effectiveness. Here, we provide an assessment of the two largest community-based management (CBM) programs in the Brazilian Amazon, which are inducing strong social and ecological benefits at a large scale. First, we show the benefits from CBM of giant arapaima, which has promoted an impressive stock recovery of the worlds largest freshwater scaled fish (Arapaima spp.), generating income and other benefits for rural livelihoods in Amazonian floodplains. Second, we show that CBM of freshwater turtles (Podocnemis spp.) has also promoted the population recovery of overexploited turtles, contributing to the maintenance of important cultural values. We also identified a set of social and institutional principles, and the intrinsic values of natural resources, which can help develop successful CBM programs. Finally, we discuss how these principles can strengthen existing initiatives and/or inspire new ones. Reconciling biodiversity conservation and local aspirations for rural development is an urgent socioecological demand in Amazonia. Raising the profile of successful initiatives can be a powerful strategy to disseminate a message of hope and action to local and international agencies that can support the scaling up of these successful models., isbn: 978-303041686-7 978-303041685-0, Pages: 99-111
