Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

Insect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained

Tropical Bee Assemblage Diversity Decreases With Elevation While Body Size Increases

Biotropica, Volume 58, Issue 4, July 2026.
Photos of bee specimens collected in the Colombian Andes across a nearly 3000 m elevational cline. They are arranged to illustrate both the decline in richness with elevation and the increase in community average body size with elevation. ABSTRACT Elevation gradients are powerful drivers of changes in species composition, richness, and functional ...

The Biology, Ecology, Distribution and Management of Two Globally Invasive Weeds: Calotropis procera (Calotrope) and Calotropis gigantea (Giant Calotrope)

Weed Research, Volume 66, Issue 3, May/June 2026.
ABSTRACT Calotropis procera and C. gigantea are emerging as globally invasive plants that can significantly alter ecosystems in areas where they have escaped from attended cultivation. Without effective management, these species can form dense monospecific stands, resulting in severe economic, environmental and social impacts.

Towards transparent and replicable flower selection in agricultural flower strips

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract Flower strips are increasingly employed as ecologically sustainable methods for attracting beneficial insects to agricultural landscapes. Since flowers differ substantially in an array of characteristics including morphology, nutritional content, and phenology, selecting “the right flowers for the right job” requires the designer to make ...
