Plant Functional Groups Mediated the Effects of Plateau Pika Disturbance and Mowing on the Community Stability of Alpine Meadow Plants

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
The response mechanisms of plant community composition, functional group biomass, vegetation‐soil properties, and community stability to plateau pika and mowing disturbance intensity exhibited distinct differences. Gramineae and Sedge aboveground biomass and soil nutrient content demonstrated more pronounced responses to both disturbances and their ...

Nectar Robbery by Native and Invasive Bumblebees Reduces Floral Rewards but Not Seed Production in Desfontainia fulgens

open access: yesEcology 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.
