Density-dependent switches in diet:a likely mechanism for negative feedbacks on goose population increase? [PDF]
Goose grazing on arctic tundra vegetation has shown both positive and negative effects on subsequent foraging conditions. To understand the potential of a density-dependent feedback on herbivore population size, the relation between grazing pressure and ...

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