Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

open access: yesInsect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Eight Years of Citizen Science Reveal Taxonomic Confusion Patterns and Dynamic Participation in the Monitoring of Vespa velutina in Spain

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The yellow‐legged hornet (Vespa velutina nigrithorax) is a successful invasive species in Europe, where its monitoring is partially reliant on citizen science (CS) initiatives. While CS is a powerful tool for early detection, taxonomic confusion and fluctuating participant engagement can limit its effectiveness.
