Comparison of Flight Periods of Solitary and Primitively Eusocial Bees in Urban Environments and Nature Conservation Areas: a Preliminary Report

open access: yesZoodiversity
Solitary and primitively eusocial bees, an important group of pollinators, have declined in the past few decades. In view of the recent focus on safeguarding pollinating insects, it is vital to understand the basic ecology of species for their ...

Bee community and trait‐based responses to fire in a Mediterranean landscape

open access: yesInsect 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

open access: yesInsect 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 ...

Unveiling the Patterns of Wild Bee‐Plant Interactions on a Large and Mostly Unexplored Mediterranean Island (Sardinia, Italy)

open access: yesEcology 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.
