Climate explains global functional trait variation in bees

open access: yesFunctional Ecology, Volume 39, Issue 7, Page 1748-1760, July 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate is a fundamental driver of macroecological patterns in functional trait variation. However, many of the traits that have outsized effects on thermal performance are complex, multi‐dimensional, and challenging to quantify at scale.

Biological Flora of Britain and Ireland: Cytisus scoparius*

open access: yesJournal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Where and What Kind—A Better Understanding of Local and Landscape Features in Planning the Urban Flower Meadows for Supporting Bee Communities

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
Our multifaceted approach revealed that the mosaics of habitats surrounding urban flower meadows are at least as necessary to support bees as the local features of UFMs. An abundance of bees responded positively to the number of flowering units, the blue and yellow colors of flowers, and increased cover of industrial areas, green urban areas, and ...
