Annual variation across functional traits: The effects of precipitation and land use on four wild bee species

open access: yesEcological Entomology, EarlyView.
We found that a dry active season increased abundance for large bees (Bombus impatiens and Xenoglossa pruinosa), whereas Agapostemon virescens and Ceratina calcarata were more abundant in wet active seasons. A dry year resulted in larger individuals with reduced foraging effort for most bees and communities were relatively more female‐biased.

‘Disease‐smart’ outcrossing can enhance individual fitness and increase survival via immune priming against pathogens: New approaches to strengthen genetic rescue efforts

open access: yesInsect Conservation and Diversity, EarlyView.
Our study provides a proof of concept for combining immune priming with assisted migration for insect conservation. Introducing genetically diverse, immune‐primed migrants improves both pathogen resistance and reproductive success in inbred individuals.

POLLINATION EFFECTIVENESS OF APIS CERANA FABRICUS AND APIS MELLIFERA LINNAEUS (HYMENOPTERA: APIDAE) IN JATROPHA CURCAS L. (EUPHORBIACEAE)

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2011
  Pollinators are well known to provide key ecosystem. Animal pollinators are thought to contribute between 15 and 30% of global food production and bees are recognized to be the most important taxon.

Exposure of Larvae of the Solitary Bee Osmia bicornis to the Honey Bee Pathogen Nosema ceranae Affects Life History [PDF]

open access: yes, 2019
Wild bees are important pollinators of wild plants and agricultural crops and they are threatened by several environmental stressors including emerging pathogens. Honey bees have been suggested as a potential source of pathogen spillover.

Local and landscape features of urban fragments determine the occurrence of stingless bees As características locais e paisagísticas dos fragmentos urbanos determinam a ocorrência de uma espécie de abelhas sem ferrão

open access: yesInsect Conservation and Diversity, EarlyView.
Both local and landscape factors associated with habitat availability and quality determine the persistence of stingless bees across fragments. Places where the species occurs have local and landscape characteristics distinctive from those where it is absent.
