Pattern of population structuring between Belgian and Estonian bumblebees [PDF]
, 2019 Several population genetic studies investigated the extent of gene flow and population connectivity in bumblebees. In general, no restriction in gene flow is considered for mainland populations of common bumblebee species.

Wilting wildflowers and bummed‐out bees: Climate change threatens US state symbols
People and Nature, EarlyView.Abstract Species designated as state symbols in the United States carry cultural importance, embody historical heritage and maintain long‐standing linkages to Indigenous traditions. However, they are threatened by climate change and even face the risk of local or global extinction.

Environmental Toxicology, EarlyView.ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Hotspots on cold mountains: Hot flowers as pollinator refuges in mountain ecosystems
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Mountain environments constrain the activity of ectothermic insects. Yet, fine‐scale thermal refuges can buffer these thermal constraints, helping insects remain active in cold conditions.
