Fantastic bees and where to find them: locating the cryptic overwintering queens of a western bumble bee

open access: yesEcosphere, 2019
Bumble bees are among the best‐studied bee groups worldwide, yet surprisingly we know almost nothing about their overwintering habitats nor the microsite characteristics that govern selection of these sites.

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

open access: yesFunctional Ecology, Volume 40, Issue 10, Page 3200-3212, October 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Coinvasional disruptions to island pollinator networks

open access: yesConservation Biology, Volume 40, Issue 5, October 2026.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

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

open access: yesEcological Entomology, Volume 51, Issue 5, Page 853-865, October 2026.
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

open access: yesEcological Entomology, Volume 51, Issue 5, Page 912-925, October 2026.
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.

Peer review of the pesticide risk assessment of the active substance Trichoderma afroharzianum (formerly harzianum) T‐22

open access: yesEFSA Journal, Volume 24, Issue 10, October 2026.
Abstract The conclusions of the European Food Safety Authority (EFSA) following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, Sweden, and co‐rapporteur Member State, Netherlands, for the pesticide active substance Trichoderma afroharzianum (formerly harzianum) T‐22 are reported.

The Plight of the Bumble Bee: The Impact of the Bumble Bee Gut Microbiome on Pathogen Infection Rates [PDF]

open access: yes, 2016
Bumble bees are one of the most common and important non-managed pollinators of agricultural crops and are therefore vital to society’s ecological and agricultural health.

Pollination services of managed common eastern bumble bees (Bombus impatiens) in seedless watermelon (Citrullus lanatus)

open access: yesJournal of Pollination Ecology
Seedless watermelon is a highly pollinator-dependent crop; in consequence, growers stock fields with managed pollinators to ensure high yields. Historically, only western honey bees (Apis mellifera) were used, but, more recently, growers have begun ...
