Experimental evidence for indirect facilitation among invasive plants
... Direct facilitation among invasive species may occur when, for example, N-fixing invasive shrubs (Hughes & Denslow 2005) or herbs (Carino & Daehler 2002) increase soil nitrogen availability, which then benefits other non-native species. Similarly, intraspecific facilitation can occur when adult invasiv ...

Herbivore
_grazing_-_20050809.jpg?width=300)
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material.
