 The Ecology of Exotic Birds in Novel Locations

Show Summary Details


This chapter considers how exotic birds interact with native species, and how they serve to re-shape global biodiversity patterns. Both exotic and native species are distributed unevenly across the environment, such that some areas house more species, and other areas house fewer. The origins of these distributions for exotic and native bird species are undoubtedly very different, yet they share several common features, such as species-area relationships on islands, and latitudinal gradients. The chapter examines whether the same processes produce the same patterns in each set of species, and what this says about the causes of distribution patterns in native species, and also in exotics. It then considers the associations that exotic species forge in their recipient communities through their biotic interactions with native species, including native birds.

Keywords: species richness; species-area relationships; biotic homogenization; Rapoport's rule; interspecific competition; predation; mutualisms; disease transmission
