简介
"Grasses and Grassland Ecology provides an ecologically orientated introduction to this influential group of plants, summarizing the most recent scientific research in ecology and agriculture in the context of the older, classic literature. Ten chapters cover the morphology, anatomy, physiology, and systematics of grasses, their population, community, and ecosystem ecology, their global distribution, and the effects of disturbance and grassland management." "This comprehensive and accessible textbook is suitable for graduate level students as well as professional researchers in the fields of plant ecology, rangeland science, crop science, and agriculture."--BOOK JACKET.
