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

Ecology, 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,

Air pollution and its multifaceted effects on insect pollinators: A review

Ecological Entomology, Volume 51, Issue 1, Page 1-17, February 2026.
Air pollution disrupts plant‐pollinator interactions by impairing floral signal transmission, altering foraging behaviour, and reducing pollinator fitness, flight efficiency, reproduction and survival, posing serious threats to ecological stability.

Pollinator communities as indicators of ecological change in developing woodlands

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
A shift in the pollinator community occurs as planted woodlands develop. Bees respond to local habitat change, while hoverflies respond to the broader landscape. The choice of metrics and sampling methods can shape ecological interpretations. Pollinators, especially bees, are sensitive, policy‐relevant indicators for tracking early biodiversity change ...
