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

open access: yesInsect 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.

EVALUATION OF POST-HARVEST OF WILD AND IMPROVED BLACKBERRY FRUITS

open access: yesTropical and Subtropical Agroecosystems
Background. Blackberry fruits are fragile and very perishable; they require various care and practices that guarantee a long shelf life. The quality of the fruits is evidenced by determining the postharvest parameters; these parameters have been ...

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

open access: yesInsect 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.

Effects of elevation and microclimatic temperatures on butterfly–flower interaction networks in a Mediterranean mountain range

open access: yesInsect Conservation and Diversity, EarlyView.
We tested how elevation and microclimate influenced butterfly–flower interaction networks at the hottest time of year in a Mediterranean mountain range. Interactions were dominated at all sites by one or two abundant butterfly and flower species, but butterfly networks were more robust to plant species loss at higher elevations. Nectar availability may

Shedding Light on Shining Leaf Chafers: Rutelinae MacLeay, 1819 (Coleoptera, Scarabaeoidea, Scarabaeidae) as a Neglected Group of Pollinators

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The interactions between insects and angiosperms date back to millions of years ago. Among the groups of pollinating animals, it is estimated that insects are responsible for pollinating more than 70% of angiosperms. Coleoptera is one of the most studied insect groups for pollination.
