The expansion of urban areas has important consequences for biodiversity, yet the abiotic drivers biodiversity in ecosystems have not been well characterized most diverse group animals on planet, arthropods. Given their great diversity, comparatively small home ranges, and ability to disperse, arthropods make an excellent model studying which factors can accurately predict biodiversity. We assessed effects (i) topography (distance natural ocean) (ii) (mean annual temperature diurnal range), (iii) anthropogenic (land value amount impervious surface) occurrence six arthropod groups represented Malaise trap collections run by BioSCAN project across Greater Los Angeles Area. found striking heterogeneity responses all both within between taxonomic groups.

The significance of urban landscapes in safeguarding biodiversity is often disregarded, even though a considerable amount conservation focus directed toward hotspots where land conversion happening at the fastest pace. Maintaining areas not only benefits environment, but along with social, economic, and technological factors can increase stability systems to disturbance, concept known as “urban resilience”. In this synthesis paper, we explore ecological dimension resilience specifically on avian because birds are easy observe, relatively abundant, serve an indicator overall health environments.

Abstract As urban areas continue to expand globally, a deeper understanding of the functioning green spaces is crucial for maintaining habitats that effectively support wildlife within our cities. Cities typically harbor wide variety nonnative vegetation, providing limited insect populations. The resulting scarcity arthropods has been increasingly linked adverse effects at higher trophic levels, such as reduced reproductive success insectivorous birds in environments. However, responses by which breeding cope with challenges food limitation remain largely unexplored. To address this knowledge gap, Central European city, we employed radiotelemetry tracking and real‐time observations on urban‐breeding female great tits' habitat use, combined detailed plant surveys video recordings nestlings' diet. This integrated approach enabled us establish direct links between foraging behavior, vegetation preferences, nestling We found besides tree canopies, tits also frequently foraged ground availability bird feeders notably affected birds' use. Foraging generally avoided plants, particularly broadleaved species. When searching food, were most time‐efficient conifers, albeit these trees provided low amounts caterpillars (a preferred prey type). Great more likely forage deliver from large native less collected fewer items abundant Our results underscore importance several factors may help improve quality birds, preserving increasing diverse being key elements endeavor.
