Book Description
The three papers in this volume summarize the previous literature on fossil vertebrates from the Bahamas, provide revisions of the previously described fossil specimens, include identifications of newly collected material, and discuss changes in the late Pleistocene environment of the Bahaman archipelago. Olson and Pregill review the history of fossil exploration in the Bahamas, describe the known fossil localities, and briefly discuss the depauperate mammalian fauna. Pregill reviews the Pleistocene herpetofauna of New Providence Island, which is similar to that found on the island today, the only extinct taxa being a tortoise (Geochelone), a crocodile (Crocodylus), an iguana (Cyclura), and a gecko of the genus Aristelliger (previously misidentified as Tarentola). Taphonomy of the New Providence deposits and the zoogeographical patterns of the herpetofauna are discussed in relation to arid climatic conditions of the Wisconsinan glacial period. It is suggested that the establishment of a north-south rainfall gradient within the Bahamas has caused more extinctions in the wetter northern islands, whereas a more diverse herpetofauna persists in the drier southern islands. Olson and Hilgartner review the fossil record of birds from the Bahamas and propose the following changes in nomenclature: Calohierax quadratus Buteo sp., Burhinus nanus Burhinus bistriatus nanus, Glaucidium dickinsoni Athene cunicularia, Otus providentiae Athene cunicularia, Bathoceleus hyphalus Melanerpes superciliaris, Corvus wetmorei Corvus nasicus. About 50% of the fossil avifauna of New Providence no longer occurs there and 40% is extinct in the Bahamas. Species composition indicates that the Bahamas in the late Pleistocene were drier and had more open savanna-like and broadleaf scrub habitats. Subsequent increases in rainfall caused habitat changes that resulted in extinction. The implications of this for modern ecological theories are discussed.

Book Description
The Natural History of the Bahamas fills a void in the literature on the avian and terrestrial species found there and is an overall excellent guide.— Sandra D. Buckner, Past President of the Bahamas National Trust Take this book with you on your next trip to the Bahamas or the Turks and Caicos Islands or keep it close to hand in your travel library. The Natural History of the Bahamas offers the most comprehensive coverage of the terrestrial and coastal flora and fauna on the islands of the Bahamas archipelago, as well as of the region's natural history and ecology. Readers will gain an appreciation for the importance of conserving the diverse lifeforms on these special Caribbean islands. A detailed introduction to the history, geology, and climate of the islands. Beautifully illustrated, with more than seven hundred color photographs showcasing the diverse plants, fungi, and animals found on the Bahamian Archipelago.

Book Description
Amphibians and reptiles are the most numerous, diverse, and frequently encountered animals on the Caribbean islands. This book provides a variety of perspectives on this amazing group of organisms. Caribbean Amphibians and Reptiles, compiled by an international team of zoologists, takes a fresh and detailed look at the complex biological puzzle of the Caribbean. The first true overview of the islands, it includes a historical examination of the people who have studied the Caribbean amphibians and reptiles. The book reviews the ecology, evolutionary history, and biogeographic explanations for the origins and diversity of the region's fauna with island-by-island coverage. It puts the Caribbean in perspective by comparing the islands to Central America and its amphibian reptile diversity. Additionally, the book includes figures, tables, and color plates which bring to life some of the region's most spectacular creatures.Key Features* Presents the first complete review of amphibians and reptiles in the Caribbean* Includes color plates and island maps* Contributors are recognized authorities in the field

Book Description
An expansive and detailed review of the biology of Caribbean amphibians, considering their threats, conservation and outlook in a changing world. Amphibians are the group of vertebrates undergoing the fastest rate of extinction; it is urgent that we understand the causes of this and find means of protecting them. This landmark illustrated volume brings together the leading experts in the field. As well as offering an overview of the region as a whole, individual chapters are devoted to each island or island-group and the measures used to protect their amphibians through legislation or nature reserves. The biological background of insular biogeography, including its methods, analysis and results, is reviewed and applied specifically to the problems of Caribbean amphibians – this includes a re-examination of patterns and general ideas about the status of amphibians in the Anthropocene. The Conservation and Biogeography of Amphibians in the Caribbean offers an important baseline against which future amphibian conservation can be measured in the face of climate change, rising sea level and a burgeoning human population. Covers over 300 species.
