Summary: Land-use change, particularly urbanisation, has led to a significant decline in both species and functional diversity worldwide. However, the mechanism behind the impact of species loss on functional diversity remains unclear. This study aims to elucidate this mechanism by examining the association between species sensitivity and functional uniqueness, as well as their related functional traits. The findings suggest that urbanisation has a remarkable effect on the taxonomic and functional diversity of macroinvertebrates, and the decline in functional diversity is influenced by the sensitivity and functional uniqueness of species.

Summary: This study investigated the relationship between microbial diversity and functional diversity in soil microbial decomposers, and whether this relationship is influenced by large mammalian herbivores. The results showed a positive correlation between functional diversity and microbial community composition, which challenges the prevailing notion of functional redundancy in hyper-diverse soil microbial communities. The relationship is favored by the availability of soil moisture. Temporal variables, such as seasonality, had a stronger impact on microbial functions than spatial variables. The study also suggests that decomposition in drylands may be particularly affected by the response of microbial species to precipitation variability.

Summary: Retention of forested buffers around streams is a common management technique to protect aquatic resources and ecosystem services. However, buffer size does not significantly affect the functional diversity of spiders and vascular plants. Other buffer variables have direct effects on their functional diversity.

Summary: This study sampled two tropical estuaries in Northwest India for two consecutive years, and assessed the taxonomic and functional structures of macroinvertebrates. The study found that natural factors such as salinity and sediment grain size were the main drivers of variations in taxonomic and functional compositions. The multiple-trait approach was effective in evaluating the resilience of estuarine benthic ecosystems. Taxonomic diversity may not be an efficient proxy for benthic functioning.

Summary: The study suggests that cyanobacterial blooms do not have a negative impact on the species diversity of phytoplankton assemblages, but they do affect the functional diversity. Cyanobacterial blooms alter dominance relations within the phytoplankton and reduce light availability, but it does not necessarily result in the elimination of other taxa or reduction in species numbers or diversity.

Summary: The study compared the functional responses of four invasive crayfish species and the most widespread native crayfish species in European freshwaters, showing species-specific impacts on key resources of benthic food webs. This highlights the importance of considering species and resource identity when assessing the ecological impact of crayfish.

Summary: The heterogeneity of the urban matrix significantly affects the species richness of woody plants in remnant forest patches, particularly when the urbanization level is high. Compositional heterogeneity of the urban matrix is positively correlated with the species richness of tree sapling/seedlings, while it is significantly associated with the species richness of shrubs when the change rate of urbanization level is low. Configurational heterogeneity of the urban matrix can enhance the correlation between patch attributes and the species richness of tree sapling/seedlings and shrubs.

Summary: The study demonstrates that species pool size has scale-dependent effects on grassland diversity, with larger pools causing greater spatial aggregation of species. This aggregation appears to result from fewer individuals arriving per species from larger pools, rather than stronger species sorting across variation in soil moisture.

Summary: In this study, a comprehensive evaluation framework was proposed to assess the resilience of urban ecological networks. Taking three typical urban agglomerations as cases, the resilience of ecological networks was evaluated from the perspectives of robustness and redundancy. The research results showed that the current ecological network exhibits redundancy. This research will contribute to the improvement of urban ecological resilience evaluation and sustainable urban management and ecological restoration.

Summary: The study found that family-level convergence in microbial communities reflects a reproducible metabolic organization, while taxonomic divergence among replicate communities arises from multistability in population dynamics. Multistability can lead to alternative functional states in closed ecosystems but not in metacommunities.

Summary: The study revealed a positive relationship between species richness and functional diversity in beetle communities in homegardens, with a saturation point indicating functional redundancy in species-rich environments. Gardener origin, homegarden area, structural complexity, and pest control strategy were identified as the most influential social-ecological filters in selectively removing beetle species based on their functional traits.

Summary: Urban resilience refers to the ability of a city or region to adapt to changes and risks. This study examines the comprehensive impacts and mechanisms of adaptation and responses to climate change by analyzing the measured level of resilience in the Tibetan Plateau region from 1991 to 2020. The results show that the level of urban resilience in the region is fluctuating and increasing, with increasing regional differences. Temperature and precipitation factors play a significant role in increasing resilience, with regional heterogeneity in their effects on different aspects of resilience.

Summary: This study investigates the effectiveness of topological decentralization for urban stormwater networks (USNs) during the planning stage. It proposes a framework to understand the impact of adding redundant flow paths on resilience and introduces a tailored graph-theory based measure. The results show that layout decentralization and the implementation of redundant paths can enhance the resilience of USNs without changing the network's major structural characteristics.

Summary: This study investigates the effects of different combinations of submerged macrophytes on water quality and submerged macrophyte communities through mesocosm experiments. The results suggest that communities with high species and functional diversity are more beneficial for improving water quality and establishing stable submerged macrophyte communities.

Summary: This research examines social-ecological and community-led urban resilience, with a focus on CanFugarolas in Mataro, Barcelona. It highlights the role of the social subsystem in driving urban progression and resilience, navigating obstacles and serving as a catalyst at the city scale. Through the case study, it demonstrates the complementary relationship between bottom-up community initiatives and top-down urban regeneration policies.
