Herbivore Tundra. We investigated the effects of warming and exclusion of large herbivores on 14 tundra taxa, three of which were common and. Here we review how herbivores influence tundra carbon and nutrient dynamics through their consumptive and. We compared the effect of small and large herbivores on tundra vegetation between four locations, two in scandinavia and two in alaska (figure 1). We show that present herbivore assemblages have large effects on tundra ecosystem composition and function and suggest that the effect on thermophilic species expected to invade the tundra in a warmer climate is especially strong, and that herbivores slow ecosystem responses to climate change. In all four locations, there are three types of exclosure treatments to exclude or permit access of small and large herbivores. Vertebrate herbivores have the potential to limit greening and shrub advance and expansion on the tundra, posing the question of whether changes in herbivore. Herbivores play a pivotal role in tundra ecosystem dynamics, influencing multiple ecosystem processes, functions, and. Here, we experimentally test effects of warming, mammalian herbivory and fertilization on tundra species richness and investigate how. Given the ongoing environmental changes in tundra ecosystems, with increased influx of boreal species and changes in the.
