Natural Systems – The Organisation of Life

Autor M Eichhorn
en Limba Engleză Paperback – 28 apr 2016
Organised into four sections, this text discusses the organisation of the living world. * Links Ecology, Biodiversity and Biogeography * Bridges modern and conventional Ecology * Builds sequentially from the concept and importance of species, through patterns of diversity to help consider global patterns of biogeography * Uses real data sets to help train in essential skills
