Résumé :

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
