دانلود کتاب The biology of African savannahs

"Savannahs form a rich mosaic of diverse ecosystems, and The Biology of the African Savannah offers an introduction to their ecology. It describes the major plants and animals that live in this habitat, and examines the biological and ecological factors that influence their populations size, interactions, and community composition. The book also discusses conservation issues such as climate change, hunting, and conflict between wildlife and domestic animals."--BOOK JACKET.  Read more... 1.
