Bangladesh lies at the crossroads of India (Gondwanan origin) and Southeast Asia (Laurasian origin), and harbors a diverse amphibian and reptile fauna. Roughly 85% of its amphibians and reptiles are facing conservation threats of various kinds. This is obviously an under-estimate since most of these survey results are over a century old. The country was plagued by war, civil revolutions, and political instability, which led to a long gap in natural history studies. Bangladesh is currently experiencing an 'age of discovery, ' and more than 42% of the amphibian species and 18% of the reptile species were first reported from the country only in the past decade. Limited and inadequate information is known on geographic distributions and natural history of these species. Extensive surveys are urgently needed for Bangladesh as a major part of its forest cover has been cleared in the last few decades. To address some of these issues, a herpetofaunal survey was conducted focusing on species diversity in different forest types in Bangladesh. The impact of the climate change on these animals has also been presented. Finally, conservation needs are discussed with management recommendations

The Diversity of Amphibians and Reptiles discusses about amphibians and ecological importance of amphibians, reptiles and relationship between amphibians and reptiles, the differences between reptiles and amphibians. It also discusses the evolution of amphibians and reptiles and the related aspects like evolution of amphibians, important characteristics of amphibians. This book also throws light on ecosystem, diversity and geographic distribution of amphibians and reptiles and it includes the related aspects like natural habitat of amphibians and reptiles, habitat loss. This book also discusses about migration of amphibians and reptiles. Also discussed in the book is diversity and distribution of amphibians, distribution of amphibians, distribution of threatened species etc. The locomotion in amphibians and reptiles and its related aspects like principles of locomotion and locomotory patterns in toads, have also been discussed.

Long celebrated for its more than 7,100 islands, the Philippines is a country in Southeast Asia that shares only with Madagascar the distinction of having been designated as both a Megadiverse Nation and a Global Biodiversity Conservation Hotspot. The terrestrial vertebrate fauna of the northeastern Philippines, specifically Luzon Island, has been the subject of intense interest since the first historical explorations. Historically, numerous works considered the biodiversity of Luzon as ?depauperate? in the sense that they was presumed to contain a reduced number of species shared with a continental mainland source. This view has persisted until recently, when a renewed interest in faunistic studies of the northern Philippines has produced a series of notable discoveries, drawing attention to high levels of species diversity and endemism in the northern reaches of the archipelago. We provide the first report on the herpetological biodiversity (amphibians and reptiles) of the northern Sierra Madre Mountain Range, northeast Luzon Island, Philippines. We combine new and historical data, and the results of recent fieldwork, to highlight at least 101 species present in this unique region of the archipelago. Not only is this fauna largely endemic (approximately 70%), but also our results add to a nascent body of literature suggesting that the northern portions of the archipelago may be substantially more diverse than currently appreciated.
