Species Turnover in Space and Time

Show Summary Details

Preview

This chapter discusses the colonization and extinction events and species turnover. It shows how, in the face of ongoing colonization and extinction events, cumulative species numbers on islands increase while the number of residents at any one time remains nearly constant. The chapter also examines the parameters that affect species turnover and cumulative species counts. Species turnover can be measured within islands over time, and also between islands over space. The chapter also discusses the distance decay phenomenon, which means that nearby islands may share more plant species than islands which are far apart, and that species turnover may increase with the distance between the islands being compared.

Keywords: colonization; extinction; species turnover; species counts; distance decay
