Species Richness: Patterns in the Diversity of Life

Patterns in the numbers of species have fascinated naturalists for centuries. Understanding the causes of latitudinal gradients in species richness and biodiversity 'hotspots' is often considered to be the holy grail of ecology. Extinctions in the past offer insight into what may occur in the future under climate change and habitat loss. The subject of vegetation-climate interaction is a compelling issue scientifically and is also of importance for land management practices.
