Summary: Freshwater ecosystems are highly threatened and effective conservation strategies should be based on understanding biodiversity patterns and drivers. In this study, the impact of environmental and dispersal-connectivity controls on freshwater diatom and fish communities was investigated. The results showed that spatial and environmental variations were key factors influencing these communities, and fish communities had stronger spatial dependency due to weaker dispersal ability. Broad-scale environmental characteristics were more predictive for fish assemblages compared to diatoms. Trait-based similarities were less affected by dispersal-connectivity effects than taxonomic datasets. This study highlights the importance of considering dispersal-connectivity processes in conservation and biomonitoring strategies.

Summary: In this study, we found that the dendritic nature of riverine systems in a Neotropical region leads to taxonomic and functional variation in fish assemblages along both lateral and longitudinal gradients, primarily influenced by spatial and spatially structured environments.

Summary: This study investigated the spatial patterns and driving factors of phytoplankton communities in the Beibu Gulf and adjacent waters in the northwestern South China Sea. The findings revealed that the relative contributions of environmental heterogeneity and dispersal limitation varied seasonally and played a crucial role in shaping the patterns of phytoplankton communities. This study provides novel insights into ocean biogeography and informs decision making for area-based marine biodiversity conservation.

Summary: Estimating changes in community composition through Species Distribution Models is important for managing the impacts of global climate change on species distributions. This study focused on freshwater ecosystems and found a trend of associations between species based on their temperature tolerances, with warmer-tolerant species dominating future community compositions. The model implemented provides a starting point for understanding climate-driven community trends and potential local extinctions.

Summary: This study examined the microbial succession patterns in the Xiaoqu liquor brewing process and their influence on flavor metabolism. Regardless of using pure starter or traditional starter, similar microbial succession patterns were observed. Changes in microbial communities during fermentation stage had an impact on metabolite synthesis.

Summary: Despite previous research, the structure of helminth communities among fish populations in the Azov-Black Sea region remains poorly understood. This study presents data on the species diversity and structure of helminth communities in 12 common fish species from the coastal waters off Crimea. The communities showed low species richness and diversity indices, but were well-aggregated and followed a core-satellite distribution. These findings expand our knowledge and have implications for monitoring and managing local fish stocks.

Summary: The study found that the environmental DNA signals of fish communities vary according to sampling period and hydromorphological conditions. While most fish communities remain similar throughout the year, specific seasonal patterns were observed. Waterflow and reproductive period have an impact on the dynamics of fish communities. Low waterflow periods are recommended for studying fish communities at a local scale to limit the effects of external environmental DNA, while high waterflow or breeding seasons are preferable for enhancing species detection probability.

Summary: This study used unsupervised machine learning to analyze the relationship between mercury bioaccumulation in fish and biogeochemical conditions and landscape, revealing that different fish species respond differently to various forms of mercury. Additionally, dissolved MeHg was found to have a significant impact on mercury bioaccumulation in fish.

Summary: The study analyzed macrolichen richness and beta-diversity along elevation gradients at three sites in the Indian Himalayan Arc area and found variations in species composition, dominant functional groups, and patterns of species richness along elevation. The research highlights the importance of considering elevational gradients in conservation strategies and emphasizes the contribution of turnover to beta-diversity across different transects in the Himalaya.

Summary: This study investigates the effects of spatial processes and environmental filtering on the beta diversity of small mammals in Sub-Saharan Africa. The results show that spatial processes are primarily influenced by dispersal ability, and there are variations in beta diversity among different small mammal taxa.

Summary: The study reveals the presence of non-random assembly of waterbird communities in wetlands generated by underground coal mining in China. To protect these waterbirds, increasing habitat diversity in wetlands is recommended, while monitoring changes in multiple biodiversity metrics is essential for ongoing management plans.

Summary: Functional connectivity disruption is a significant characteristic of schizophrenia, but the heterogeneity of patterns reported across different sites has hindered its clinical generalization. This study compared different correction methods and identified three replicable subnets of disrupted functional connectivities in schizophrenia patients.

Summary: This study aimed to understand spatial-temporal changes in coastal communities in the context of climate change in Galicia rias. The research found significant changes in seaweed communities between 1998 and 2014, with temporal beta-diversity mainly related to species loss and spatial beta-diversity significantly higher in 2014. Nitrate concentration was identified as the main driver of both temporal and spatial beta-diversity patterns.

Summary: The freshwater pearl mussel Margaritifera margaritifera is facing population declines in Europe, and the inclusion of fish hosts' occurrence data in species distribution models can improve predictions. Climate change poses a particular threat to the mussel-fish dynamics. The future distribution of M. margaritifera is expected to contract, with current protected areas failing to safeguard the species. This study highlights the importance of including biotic interactions, such as host species, in distribution models and informs conservation strategies.

Summary: This study investigated the network structures between epiphytic bryophytes and their hosts in tropical and subtropical forests, revealing nested relationships, low modularity, and specialization levels. The vertical distribution of bryophyte species showed structured modules within tree basal and crown zones. The high nestedness may stabilize ecological networks, while low modularity and specialization suggest less colonization of specific host species by epiphytes.
