Pollination Under Pressure: Grazing and Nutrient Enrichment Reshape Arctic Pollinator Communities and Interaction Networks. [PDF]
Grazing exclusion reshaped Arctic flower‐visitor communities, increased plant‐pollinator interactions, and altered interaction networks, while nutrient enrichment had weaker, context‐dependent effects. Together the two drivers produced both independent and interactive effects, with tundra grasslands showing the greatest sensitivity to environmental ...
