Herbivore decline switches a high Arctic plant community from top‐down to bottom‐up control
Journal of Ecology, Volume 114, Issue 4, April 2026.Declining abundance of large herbivores in the Arctic loosens the top‐down control on the vegetation, which now responds primarily to the changing climatic conditions and follows the general greening pattern observed in a warming Arctic. These changes may impact terrestrial ecosystem element cycling, with knock‐on effects on the dynamics in adjacent ...
