African savannas and their large mammals strength and direction of herbivores’ effects depend on the impacts of large herbivores on.
In addition to these negative effects, large herbivores can have positive effects on long-distance dispersal (reviewed in nathan et al, 2008) and thus on species colonization large herbivores can also positively affect plant population growth rate by enhancing seedling recruitment (reviewed by maron and crone, 2006. Climate change effect on plant communities is buffered by large herbivores who simulated climate change and integrated the effects of large.

The results of the research suggest that plant communities in the arctic are more likely to resist destabilization by climate change if populations of caribou, musk ox, and other large herbivores remain intact. In any system large herbivores can interact either directly or indirectly with other species of animals through the activities that herbivores bring about (figure 61), direct competition may take.
