Habitat fragmentation affects plant–arthropod interactions through connectivity loss and edge effects

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Habitat fragmentation is widespread globally, but the effects of fragmentation on populations and communities are often unclear. Because species responses to fragmentation are interdependent, examining how fragmentation alters species interactions may clarify community responses to fragmentation. In a large, replicated fragmentation experiment,

Effects of flower patch additions and urbanisation on cavity‐nesting bees and wasps

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Urbanisation can negatively affect cavity‐nesting bees and wasps, yet common conservation interventions such as flower patches and artificial nests lack strong empirical support. In a 2‐year experiment across urban allotments spanning an urbanisation gradient, we found no effect of added floral resources on nest uptake, while hymenopteran abundance ...

Bee on Boron—Sufficient Boron Supply of Brassica napus Is Crucial for Attracting Pollinating Insects to Ensure Seed Yield

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The study demonstrates that sufficient B supply is crucial for successful rapeseed flower growth and fertility as well as for attracting pollinating insects, thus securing yield in a pollinator‐dependent crop. It is illustrated that climate change can pose a threat to crop yield via both direct effects, that is, an impaired nutrient uptake, and ...

Biodiversity and Conservation Challenges in the Alédjo Wildlife Reserve (AWR) in Togo: Insights From Ethnozoological Surveys

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).
