Summary: This study examined the relationship between LCBD, SCBD, and rarity of spider community in the riparian habitat of the Ganga River. The LCBD of the spider community was significantly correlated with total species richness but not with rare species richness. Spider species with intermediate occurrence contributed more to SCBD values than species with high and low occurrence. The rarity index of spider species had a significant relationship with SCBD values.

Summary: This study investigated the effects of eutrophication on microbial community structure in shallow lakes in the Yangtze-Huaihe River basin in China. The results showed that eutrophication led to the homogenization of bacterial and fungal communities in both water and sediments. Physicochemical factors such as water temperature, pH, and heavy metals were found to influence the community structure. Importantly, generalist species were found to play a dominant role in explaining the variations in beta diversity along the trophic gradient.

Summary: The introduction of non-native fish species poses a threat to native fish populations in floodplain systems. Establishing oxbow lake-based conservation areas is proposed as a practical approach to mitigate this threat. This study examines the temporal changes in fish community diversity in 28 oxbow lakes along the Ishikari River in Japan over a decade and finds that upstream lakes maintain high levels of native uniqueness while downstream lakes experience increased non-native fish diversity. The study highlights the importance of prioritizing conservation efforts in the upper reaches as they serve as refuges for native fish.

Summary: In a scenario where escalating human activities lead to environmental changes affecting mammal abundance and distribution, beta-diversity may increase due to site differences. The study analyzed beta-diversity patterns of ground-dwelling mammal communities and found that LCBD was primarily influenced by species richness, while SCBD was more related to occupancy and relative abundance. Local II diversity was driven by species replacements, revealing the regional status of mammal diversity.

Summary: Understanding how biotic communities are spatially organized is important for landscape-scale biodiversity conservation. Local contribution to beta diversity (LCBD) can help identify key habitats for conservation within habitat networks. By incorporating LCBD and sites with high taxonomic diversity into conservation prioritization approaches, the effectiveness of conservation actions within pond habitat networks can be improved to protect high biodiversity sites and define a spatial network of protected sites. New, effective conservation approaches are essential in urban areas to ensure biodiversity is supported and harmful human impacts are reduced.

Summary: The Neotropics have the highest diversity of freshwater fish on Earth, with the Auchenipteridae driftwood catfishes being a representative group. However, there are gaps in taxonomy, geographic distribution, evolutionary relationships, and feeding habits of these fish. Research shows a significant number of species remain undescribed, with under-sampling in terms of distribution and feeding habits. More effort is needed from taxonomists, ecologists, and biogeographers to fill these knowledge gaps in fish systematic biology.

Summary: Common and rare species exhibit different responses to environmental and spatial variables, especially in the face of human disturbances. The loss of common species typically leads to a decrease in local redundancy, while rare species are more vulnerable to landscape changes. However, the importance and conservation status of rare species are often overlooked.

Summary: Local communities and individual species contribute to the overall beta diversity in metacommunities. This study investigated the local contribution (LCBD) and species contribution (SCBD) of stream benthic diatoms and insects along a gradient of land use intensification in southeast subtropical Brazil. The results showed that LCBD was negatively related to forest cover and positively related to environmental and land use uniqueness. Additionally, SCBD was partly explained by species traits and taxonomic relatedness and exhibited different relationships with forest cover for diatoms and insects.

Summary: Land-use and land-cover transitions have various effects on biodiversity and ecosystem functioning, including energy transfer within food webs. Our study examined changes in the size spectrum of aquatic macroinvertebrates along a land-use intensification gradient in Brazilian streams. We found that disturbed streams had fewer small organisms but more efficient energy transfer compared to pristine forest streams. Despite this efficiency, disturbed streams had lower taxonomic diversity and supported fewer large organisms and shorter food chains.

Summary: By studying multiple datasets on fish abundance in 541 streams, we found that communities composed of small populations are more spatially variable and less related to the environment variation than communities composed of large populations. Our results indicate that community size affects the strength of ecological drift and environmental selection in metacommunities, and further declines in population and ecosystem size can make spatial variation in biodiversity more unpredictable.

Summary: Temporal variability in ecological structure and processes tends to decrease with increasing spatial scales and levels of biological organization. However, the patterns and mechanisms of variability across trophic levels remain poorly understood. In this study, we analyzed abundance time series data from spatially structured communities and found that temporal variability in abundance decreases from producers to tertiary consumers, mainly at the local scale. Synchrony within sites increases with trophic level, while synchrony among communities decreases.
