ECOLOGY:
Enhanced: Caribbean Catastrophes

Thomas Brooks and Michael Leonard Smith

The number of species on islands is generally viewed as reflecting a balance between colonization and extinction. In a Perspective, Brooks and Smith explain the diverging conclusions of two recent studies of Caribbean island populations of lizards (Schoener et al.) and birds (Ricklefs and Bermingham). The Perspective authors propose a solution to the problem and discuss the implications for conservation of island populations.
