Urban fragmentation leads to lower floral diversity, with knock-on impacts on bee biodiversity

P. Theodorou, S. Herbst, et al.

This study reveals the critical relationship between bee and flowering plant diversity in urban settings, showcasing how urban fragmentation can threaten these vital ecosystems. Conducted by a team of researchers including Panagiotis Theodorou, Sarah-Christine Herbst, and others, the findings underscore the need for urban planning that preserves biodiversity.

Abstract
This study investigated the co-variation of bee and flowering plant richness and diversity in urban green spaces, focusing on the effects of urban fragmentation. Bee abundance and richness were positively related to flowering plant richness, with bee body size increasing with nectar-holder depth of flowering plants. Causal modeling indicated that urban fragmentation negatively impacted flowering plant richness, indirectly reducing bee species richness and abundance. The strong bee-plant interdependence highlights the risks of parallel declines due to land-use change.
