Bee community and trait‐based responses to fire in a Mediterranean landscape
Insect Conservation and Diversity, Volume 19, Issue 3, Page 530-547, May 2026.Fire drives a short‐term increase in bee abundance and diversity, despite its strong negative impact on floral resources. Acting as an environmental filter, fire shapes bee communities as increased post‐fire fine‐scale heterogeneity favors bees with specific functional traits such as ground‐nesting and generalist species.

Estimating wild bee population size with validated distance sampling
Insect Conservation and Diversity, Volume 19, Issue 3, Page 469-483, May 2026.Distance Sampling is a promising method to estimate population size but has never been validated on insects. We validated it on a honey bee population of known size. We applied Distance Sampling to three insular pollinators and found that estimates are consistent across days, match species phenology and reflect the expected influence of weather ...

Journal of Apicultural Science, 2015 Many varieties of sweet cherry are self-incompatible. Therefore, sweet cherry orchards require a huge population of pollinator bees to carry out an adequate amount of pollen transfer between the different varieties.

Ecology and Evolution, Volume 16, Issue 4, April 2026.An extensive survey of wild bee and bee–plant networks in Sardinia (Italy) highlights high species richness and diversity, particularly in mainland agroecosystems. All interaction networks were highly specialized, modular, and not nested, indicating potential ecological vulnerability, though varying across sites and on a temporal scale.
