Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Eusocial bee species are exposed to different toxic element profiles despite foraging within the same landscape

Ecological Entomology, EarlyView.
Bombus terrestris and Apis mellifera colonies sharing the same landscape (<50 m from each other) collected pollen with significantly different heavy metal concentrations. B. terrestris‐collected pollen contained 2–7× higher concentrations of arsenic, chromium, cobalt, lead and tin than A. mellifera‐collected pollen.

Direct and indirect effects of land use on microbiomes of trap-nesting solitary bee larvae and nests

Frontiers in Microbiology
IntroductionThe global decline in biodiversity and insect populations highlights the urgent need to conserve ecosystem functions, such as plant pollination by solitary bees.

Forest edges buffer effects of agricultural management on bee–plant interaction networks

Ecological Entomology, EarlyView.
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Morphological and Histological Structure of Adexinal Glands of some Solitary Bee Species (Hymenoptera – Apoidea)

Sociobiology
Solitary bees are diverse and very important for plant and crop pollination. They are extensively studied taxonomically, but little is known about their anatomy and physiology compared to honey bees.

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

Ecological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...

Spinoza on Humans as Social Animals

European Journal of Philosophy, EarlyView.
Abstract Spinoza repeatedly suggests that humans are set apart from other animals by their rational and moral abilities. Yet he disparages the traditional definition of the human as a ‘rational animal’ and several of his other views suggest that these abilities are not sufficient by themselves to characterize human nature.

The Mechanics of Critique

European Journal of Philosophy, EarlyView.
Abstract Immanent critique is often presented as a distinctive approach to political and social philosophy. But Rachel Fraser argues that immanent critique cannot satisfy three plausible criteria that characterise it as a distinctive approach: it cannot be normatively significant, social, and make no appeal to external standards.
