Summary: The study found that plant species diversity was similar in both rock and soil site types in karst terrain; trees and shrubs were mainly distributed randomly within the study area. Trees growing on rock had smaller diameter, height, and basal area compared to trees growing on soil. Abiotic environmental variables had varying effects on tree diversity and size at the two site types.

Summary: Spatial patterns of species richness show a positive correlation, known as cross-taxon congruence, with temperature being a major driver. Temperature influences plant richness directly and orthopteran richness indirectly. Cross-taxon congruence is likely due to a common response to temperature by both taxa but through different mechanisms.

Summary: This study investigated the plant diversity in wetlands along the middle and lower reaches of the Yellow River. A total of 184 plant species belonging to 52 families and 135 genera were found in the seven nature reserves. The results showed that both environmental factors and human disturbance factors influenced the plant diversity in these wetlands.

Summary: This study explored the relationships between forest mammal diversity and various factors, such as elevation range, contemporary climate, paleoclimate change, and human activities in China. The results showed that higher elevation range and increased contemporary precipitation and cropland area were associated with higher mammal species richness and improved phylogenetic diversity and structure.

Summary: This study synthesized global knowledge about the relationship between spatial environmental heterogeneity (EH) and freshwater biodiversity through a systematic review and meta-analysis. The results showed a positive effect of spatial EH on taxonomic and functional alpha diversity. However, the overall effect on beta diversity remains uncertain. The study also discussed the mechanisms explaining this relationship and its implications for freshwater ecosystem management.

Summary: Habitat heterogeneity is a primary driver of biodiversity patterns, but its universal role has not been fully understood due to a lack of coordinated experiments. This study conducted 22 experiments to assess the impact of habitat heterogeneity on biodiversity across different ecosystems and regions, and found that positive and additive effects were common across the three axes of heterogeneity. These findings provide mechanistic insights into the importance of habitat heterogeneity in promoting biodiversity through facilitative interactions.

Summary: The study found that small-scale habitat heterogeneity within and among tributaries influences the spatial and temporal variation in fish assemblages in the Three Gorges Reservoir. Different habitats were dominated by piscivorous, limnophilic, and mid-pelagic species. Spatial variation in fish assemblage structure was observed between lower and upper reaches and among tributaries. Seasonal variation was mainly related to environmental factors such as water depth, temperature, dissolved oxygen, and pH. The results support the need to protect tributaries that contribute to fish diversity in large reservoirs.

Summary: This study proposes a rapid assessment method for biodiversity on eco-friendly farms and confirms the suitability of the ABI scoring system. Results show that farm area and the proportion and diversity of natural/seminatural habitats are significantly correlated with ABI scores, indicating the positive contribution of eco-friendly farms to biodiversity conservation.

Summary: The influence of island dynamics and characteristics on different facets of plant diversity, including functional and phylogenetic diversity, is explored using barrier islands. Island area is found to be the best predictor for all diversity facets. Larger islands have higher functional and phylogenetic diversity, while smaller islands have lower diversity. Habitat heterogeneity also affects diversity, with increased competition on smaller islands leading to potential trade-offs between area and heterogeneity.

Summary: This study examined the impact of five vegetation types on butterfly assemblages at a small scale in the Southern Amazon region. It found that different vegetation types influenced the composition and diversity of butterfly communities. The differences may be due to factors such as light levels, temperatures, humidity, and host plant availability. The results suggest that the presence of various vegetation types in the region promotes the coexistence of butterfly species and conservation efforts should address specific threats to each vegetation type.

Summary: Changes to natural environments resulting from human population growth pose a major threat to biodiversity. This study found that vegetation structure, patch size, and isolation distance significantly influenced avian communities, with reductions in forest patch size and complexity leading to decreased avian species richness and functional diversity. Additionally, increasing isolation distance had a negative impact on avian diversity.

Summary: The relationship between population genetic structure and metacommunity structure is still unknown, but regional variation in environmental characteristics and spatial structure influences resulting biodiversity patterns differently. Metapopulations and metacommunities both exhibit greater spatial and environmental structuring at larger spatial scales, responding to different subsets of environmental variables.

Summary: The study examined the composition and diversity of crustacean zooplankton across different spatial scales in Canada. The results showed distinct differences in taxonomic and functional composition when considered by continental basin, with alpha-diversity varying greatly across space. Beta-diversity was mainly driven by richness differences across all spatial and biodiversity dimensions.

Summary: This study examined the resistance and resilience of bacterioplankton communities to common pesticides, showing that high doses of glyphosate altered community structure while maintaining functional redundancy. Communities exhibited resilience at broad taxonomic levels, but not at finer taxonomic resolution. Long-term impacts of glyphosate at finer taxonomic levels require further investigation.

Summary: In phytoplankton communities, spatial overlap may promote competitive exclusion and reduce taxonomic diversity, while also fostering functional diversity. This study found that alterations in lake physical structure and zooplankton community had a stronger impact on phytoplankton diversity than spatial overlap. However, some effects of spatial overlap on competitive interactions were still observable in the system.

Summary: Canada has a fragmented understanding of the ecological status of its lakes, which are home to many bioindicators called zooplankton. Factors like lake morphometry and water quality significantly influence the diversity and composition of zooplankton communities. The effect of environmental drivers on zooplankton varies across different continental watersheds in Canada.

Summary: This study aims to understand how and where assemblages of a central food web component of freshwater lakes have changed over the course of industrialization in relation to land use. The research found that contemporary assemblages in highly impacted lakes were less diverse both taxonomically and functionally compared to pre-industrial assemblages. While spatial homogenization did not increase as expected, temporal turnover showed a non-significant but increasing trend in highly impacted lakes, especially in urbanized watersheds. The study contributes to our understanding of the health status of Canadian lakes and the impacts of human activities, particularly agriculture and urbanization, on lake zooplankton.

Summary: This study examined the effects of functional traits and diversity on crustacean zooplankton productivity in 84 Canadian lakes. The study found that zooplankton production rates were positively linked to dominance by specific feeding traits (Daphnia filtration and Chydorus filtration) with lower functional evenness. After accounting for environmental factors, the effect of functional composition on production was comparable to the aggregate effect of environmental variables. Therefore, the functional community structure of zooplankton plays an important role in regulating a pivotal lake ecosystem function.

Summary: Climate change effects are already being felt around the globe, and governance systems need to adapt to foster greater resilience in social-ecological systems (SES). Anticipatory governance is proposed as a concept for this purpose, but its definition and practical use remain vague. This paper reviews the concept and analyzes two social-ecological systems to identify criteria and opportunities for anticipatory governance.
