Background: Climate change is altering climate patterns, mainly increasing the frequency and intensity of extreme events with potentially serious impacts on natural resources and the people that use them. Adapting to such impacts will require the integration of scientific and local (folk) knowledge, especially the first-hand experiences and perceptions of resource users such as fishers. In this study, we identify how commercial riverine fishers in the Amazon remember extreme climatic events (flood and drought) and how they face the consequences of extreme events on fish availability. Methods: Data were collected from the main Manaus fishery harbor between June and October of 2013. Semi-structured questionnaires and a historical timeline technique were used to gather data from artisanal commercial fishers. Fishers' knowledge of extreme climate events was assessed by their cultural consensus for identification of event years and perceived impacts. Fishers' responses were also compared to hydrological data to test their similarity. Results: There was a high level of cultural consensus among fishers about extreme events years. They were able to identify four consecutive unusual droughts, between 2009 and 2012. Elevated levels of fish mortality and decreases in the fishery were perceived as consequences of the drought events, as well as, a reduction in fish size, and disappearance of some species. Extreme flood events were associated with greater difficulties accessing fishing grounds. Conclusions: Extreme climatic events (floods and droughts) were remembered, and the recent increase in their intensity and frequency was also perceived. Moreover, extreme climate event (mainly droughts) impacts on fishery resources were also observed. Such information is potentially valuable for educational programs to further improve adaptation of local Amazonian fishing communities to future climate change, e.g. increasing local ecological knowledge using learning material based on their perception.

Seasonal rainfall influences reproduction and recruitment of tropical penaeid shrimps: Implications to fisheries management

Matheus Souza Ferreira de Barros, Jose Gilmar Cavalcante Oliveira Junior, Cicero Diogo Lins Oliveira, Taciana Kramer Pinto, Vandick da Silva Batista, Nidia Noemi Fabre

Summary: This study investigates the reproductive dynamics of two shrimp species in major fishing grounds in Northeastern Brazil. The results show that recruitment and reproduction periods overlap significantly, with recruitment occurring in the wet season and spawning in the dry season. The study suggests that both species have evolved to maximize reproductive fitness by recruiting in the wet season and spawning in the dry season. It also highlights the negative influence of climate change on tropical shrimp stocks and the need for adjusting local regulations to protect them from overfishing.

Summary: This study assessed the case of arapaima co-management through the lens of the Protected Areas Asset Framework (PAAF). It found that arapaima is recognized as a key biophysical natural asset by local communities, with significant importance in terms of food, cultural, economic and conservation aspects. The study highlights the potential of PAAF in identifying the diverse range of values associated with protected areas and encourages stronger support for collaborative sustainable natural resource management programs.

Summary: This study assessed the socioeconomic vulnerability of human communities in Brazilian MPAs affected by a major oil spill in the southwestern Atlantic. The findings revealed a high vulnerability of these protected areas to oil accidents, particularly impacting food security for traditional communities.

Summary: This study fills the research gap on small mammals in the Caatinga biome and provides detailed information on species richness, composition, and some biometric data. The dataset, which is the first of its kind for the Caatinga biome, has considerable potential value for studying habitat use, landscape ecology, macroecology, biogeography, and conservation.

Publication trends in global biodiversity research on protected areas

Sonia Llorente-Culebras, Richard J. Ladle, Ana M. C. Santos

Summary: One of the main strategies to reduce global loss of biodiversity is the establishment of protected areas. However, biodiversity knowledge is biased taxonomically and geographically, and there are shortfalls and biases in the research conducted in protected areas. Reducing these biases and shortfalls is essential for more effective use of limited conservation resources.

Assessing interspecific variation in life-history traits of three sympatric tropical mullets using age, growth and otolith allometry

Jordana Rangely, Matheus S. F. de Barros, Monica D. Albuquerque-Tenorio, Reginaldo Medeiros, Richard James Ladle, Nidia Noemi Fabre

Summary: Life history theory predicts that organisms optimize their life-history traits according to evolutionary context and environmental constraints. In this study, we investigated life-history traits of three tropical mullet species using age, growth, and otolith allometry. Our results indicate that otolith allometric patterns are useful predictors of specific life history traits. More generally, our study species exhibit fine-scale temporal differences in life cycle events that may be related to growth rates and body size that can be predicted by otolith allometry, as well as a gradient of interspecific divergences in life-history traits.

Summary: Societal awareness and engagement with environmental problems are crucial for effective conservation programs. Research shows that public attention to cultural products decreases over time, which could also limit motivation for conservation efforts. This study addresses the concept of attention transience in conservation, discusses its drivers and mechanisms, and provides an overview of conservation issues for which it is particularly relevant. Attention transience allows conservationists a brief opportunity to focus public awareness and mobilize support, emphasizing the importance of tailored marketing campaigns, targeted communication, and efforts to refocus attention on key issues.

Patterns and trends in scientific production on marine elasmobranchs: research hotspots and emerging themes for conservation

Cicero Diogo Lins De Oliveira, Richard J. Ladle, Vandick Da Silva Batista

Summary: Elasmobranchs, including sharks and rays, are facing the threat of endangerment globally. A scientometric analysis was conducted to investigate the scientific production on elasmobranchs between 1950 and 2019. The study found an exponential increase in the number of valid articles on elasmobranchs. The research focus shifted from descriptive biology to themes related to life history, conservation, and fisheries. However, there is a lack of explicit studies on elasmobranch conservation, especially in Asian countries where overexploitation poses significant threats.

Summary: We believe that naming species after individuals is unfair and goes against principles of equality and representation. Reforming taxonomy to eliminate eponyms may be challenging, but it can have numerous advantages for both conservation and society.

Summary: This study investigates the perceptions of Brazilian artisanal fishers on the cultural, economic, governance, health, and social contributions of artisanal fishing to their well-being. The results show that fishers from different areas have significantly different perceptions of the benefits of artisanal fishing. The research provides a multidimensional perspective on the benefits generated by artisanal fishing in Brazil, supporting the management and governance of the industry to increase the well-being of fishing communities and conserve fisheries resources.

Factors influencing risk perception of inshore and offshore artisanal fishers in a marine protected area in Brazil

Aline Olimpo dos Santos, Cicero Diogo L. Oliveira, Jose Gilmar C. de Oliveira Junior, Vandick da Silva Batista

Summary: Artisanal small-scale fisheries play a crucial role in subsistence and food security, particularly in developing countries. However, these fishers face various challenges such as economic and social marginalization, conflicts, and overfishing. This study explores the risk perception among artisanal fishers in a Marine Protected Area through interviews and questionnaires. The findings suggest that fishing environment positively influences risk perception, while a lack of religious beliefs has a negative impact. Offshore fishers experience more operating conditions and time at sea, leading to higher risk of losses and greater perception of health and conflict risks. Inshore fishers, on the other hand, have a higher perception of environmental degradation.
