Herbivory and nutrient limitation protect warming tundra from lowland species’ invasion and diversity loss
Abstract Herbivory and nutrient limitation can increase the resistance of temperature‐limited systems to invasions under climate warming. We imported seeds of lowland species to tundra under factorial treatments of warming, fertilization, herbivore exclusion and biomass removal. We show that warming...
