Floral resource diversification promotes solitary bee reproduction and may offset insecticide effects – evidence from a semi‐field experiment

open access: yes, 2021
Pollinator declines in agricultural landscapes are driven by multiple stressors, but potential interactions of these remain poorly studied. Using a highly replicated semi‐field study with 56 mesocosms of varying wild plant diversity (2–16 species) and ...

Bionomy and Nesting Behavior of the Bee Epanthidium tigrinum (Schrottky, 1905) (Hymenoptera: Megachilidae) in Trap-Nests

open access: yesSociobiology, 2020
About 85% of pollinating bees are solitary, but few are used for agricultural pollination. The Anthidiini tribe looks very promising in Brazil, in the light of ecosystem utility, but  it is still a species with poorly scientific research[EdM1] .

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

open access: yesEcological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

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

open access: yesEcological 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 ...

Multilevel spatial structure impacts on the pollination services of Comarum palustre (Rosaceae).

open access: yesPLoS ONE, 2014
Habitat destruction and fragmentation accelerate pollinator decline, consequently disrupting ecosystem processes such as pollination. To date, the impacts of multilevel spatial structure on pollination services have rarely been addressed.

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

open access: yesEcological 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.

Spinoza on Humans as Social Animals

open access: yesEuropean 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.

Characterizing Solitary Bee Communities In The Southern Appalachians And Environmental Factors Predicting Habitat Use [PDF]

open access: yes, 2023
Pollinators, particularly bees, provide essential services for both agricultural and ecosystems worldwide, but data has accumulated documenting population declines, range shifts, and range contractions for many species. Most bee species are understudied,
