Localised patterns of wild bee abundance indicate woodlands play multiple roles in supporting farmland populations

Insect Conservation and Diversity, EarlyView.
Across 12 farmland sites, we deployed wild bee traps in deciduous woodland canopies and understories, and in an open habitat (at field margins) before and after canopy closure. Post‐canopy closure, understory activity (relative to field margins) generally decreased, but higher temperatures may have increased its likelihood.

Associations between soil characteristics and ground‐nesting bees on farms Associations entre les caractéristiques du sol et les abeilles terricoles dans les exploitations agricoles

Insect Conservation and Diversity, EarlyView.
We collected ground‐nesting bees at 35 farms over two summers and assessed their abundance, diversity, and community composition in relation to local soil characteristics (texture, compaction, slope, and ground cover). Ground‐nesting bee abundance and species richness increased with bare ground and sand content.

Pollen exploitation by non‐native, feral honey bees: Potential consequences for interspecific competition

Insect Conservation and Diversity, EarlyView.
In Southern California, a global hotspot of bee biodiversity, predominantly feral populations of the exotic western honey bee constitute an estimated 90% of individual bees and 98% of bee biomass. Honey bee foragers remove 80% of total pollen during the first day flowers open on three common native species, with their first two visits removing over 60%

A trait‐based framework to understand and predict the response of wild bee functional groups to anthropogenic landscapes

Insect Conservation and Diversity, EarlyView.
Wild bee functional groups consist of species that are grouped together based on their similarity in multiple nesting and foraging traits. These functional groups have their own specific association with suitable habitats and urban or agricultural landscapes.
