Moderate Seasonal Grazing During the Seed‐Set Stage Is Detrimental to Seed Rain and the Soil Seed Bank in an Alpine Meadow

open access: yesJournal of Vegetation Science, Volume 37, Issue 1, January/February 2026.
We investigated the characteristics of temporal (different years) and spatial (different seasonal pastures) variations in species richness and density of the aboveground vegetation, seed rain, and transient soil seed bank under moderate seasonal grazing in an alpine meadow, Qinghai‐Tibetan Plateau.

Weed biodiversity and herbicide intensity as linked via a decision support system

open access: yesPest Management Science, Volume 81, Issue 10, Page 6667-6677, October 2025.
A high Shannon diversity of weed species leads to low herbicide intensity. The decision support system reduces herbicide intensity at low weed densities and thus supports biodiversity. Abstract BACKGROUND Extensive herbicide use is one reason for the declining biodiversity of arable weeds. This study aimed to investigate (i) whether herbicide decisions
