Integrating Population Genomics and Historical Occurrence Data to Assess the Impact of Land‐Use Changes on Centris Oil Bees in the Brazilian Cerrado

open access: yesMolecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Habitat loss and fragmentation (HLF) are among the major drivers of bee decline, yet closely related species often show contrasting responses depending on their ecological and demographic traits. The Brazilian Cerrado biodiversity hotspot experiences among the world's highest rates of HLF.

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.

Superinfection Exclusion in Neotropical Honey Bees May Block DWV‐B, an Emerging Infectious Disease Variant of Deformed Wing Virus

open access: yesEvolutionary Applications, Volume 18, Issue 8, August 2025.
ABSTRACT RNA viruses often comprise multiple variants that co‐circulate in a host population, with potentially complex dynamics. Deformed wing virus (DWV), arguably the most impactful virus of honey bees (Apis mellifera), nowadays exists as two major variants, genotypes A (DWV‐A) and B (DWV‐B), which provide an amenable window into the dynamics of ...
