Islands and Snakes

Book excerpt: In this follow-up to Islands and Snakes, this book contains 15 chapters describing diversity and conservation of snakes on islands, with foci on selected island systems not previously summarized. Attendant topics include biogeography, plasticity and evolutionary responses to insular conditions, invasive species, importance and collapse of trophic systems, threats to insular snake populations, and strategies of conservation to save them. Chapters include descriptions of snake faunas on larger islands such as Borneo and New Guinea; reproductive biology of insular snakes; phenotypic evolution; physiology and growth patterns related to diet and environment; patterns of endemism; taxonomy of snake radiations; and history of invasions by snakes on islands. The final chapter presents a discussion of prospects and overview of conservation of snakes on islands. Chapters are contributed by international authorities on respective island-and-snake systems. The latter include some islands or archipelagos that are young, or of high importance, or support snake populations that were previously not well known. The content includes colourful photographs, informative illustrations, and in some cases synthesis of new data relevant to the importance of islands for understanding the ecological underpinnings and genesis of biodiversity. Each chapter is appropriately referenced with citations to scientific literature, and where useful, footnotes, tables and graphic information supporting the narrative of the respective subject matter. The overall presentation is intended to provide readers with an enhanced appreciation for islands and the spectacular snakes that might live there.
