Plant Biology, EarlyView.Expression of genetic differences depends on the experimental environment as seen in flowering time differences between ancestors and descendants that emerge in climate chambers but not in greenhouse or garden conditions. Abstract Common‐environment experiments are important to study genetically based phenotypic variation within and among plant ...

Ecology and Evolution, Volume 16, Issue 7, July 2026.Terrestrial eDNA analysis is currently revolutionizing our ability to monitor arthropod plant interactions. But while the approach has been shown to accurately recover arthropod communities which interacted with a flower, its quantitative capabilities are limited.

Ecology and Evolution, Volume 16, Issue 7, July 2026.We evaluated nectar robbery by native and invasive bumblebees in the hummingbird‐pollinated shrub Desfontainia fulgens in southern Chile. Nectar robbery strongly reduced nectar standing crop and altered floral visitation patterns, but these proximate effects did not translate into reduced seed production under natural pollination conditions.

Generalist passerine birds perform a functional role as pollinators in temperate Europe
Journal of Ecology, Volume 114, Issue 7, July 2026.Nectar‐feeding birds are effective pollinators. In temperate Europe, songbirds visit flowers but lack specialist traits, so functional pollination has been discounted. We use observations, pollen identification and experiments to demonstrate that generalist birds affect fruit‐set of flowering trees.
