British and Irish butterflies: an island perspective.

Book cover for British and Irish butterflies: an island perspective.

Description

This book provides a brief overview of the fast developing research on the butterflies of the islands over the past 20 years. The first three chapters introduce basic topics in island biogeography, past environments and aspects of butterfly biology and study. Chapters 4 to 6 drop down in scale from a broad view of butterfly geography over Britain and the European islands to finer issues affecting ...

Chapter 6 (Page no: 88)

Assessing the status of individual species on islands: from geography to ecology.

An important issue emerging in more recent years is that to understand the presence of species on islands, greater attention needs to be paid to species life histories and ecology: measures of island geography, in themselves, provide valuable but insufficient predictors of the occurrence of different species' on particular islands. Moreover, resource and life history traits of species occurring on islands (community or faunal ecology) should reflect the impact of island geography on those species. In this chapter, then, a move is made from geography to ecology; in particular, attention is focused on two indices of migration capacity and colonization ability and their implications for butterfly island occupancy.
