Volumes in the Trends in Linguistics. Documentation series focus on the presentation of linguistic data. The series addresses the sustained interest in linguistic descriptions, dictionaries, grammars and editions of under-described and hitherto undocumented languages. All world-regions and time periods are represented.

This study offers a pragmatic dimension to World Englishes research. It is particularly timely because pragmatics has generally been understudied in past research on World Englishes, especially postcolonial Englishes. Apart from drawing attention to the paucity of research, the book also contributes to theory formation on the emerging theoretical framework, postcolonial pragmatics, which is then applied to data from two World (postcolonial) Englishes, Ghanaian and Cameroon Englishes. The copious examples used clearly illustrate how postcolonial societies realise various pragmatic phenomena, in this case offers and offer refusals, and how these could be fruitfully explained using an analytical framework designed on the complex internal set ups of these societies. For research on social interaction in these societies to be representative, it has to take into account the complex history of their evolution, contact with other systems during colonialism, and the heritages thereof. This book does just that.

Destruction of habitat due to urban sprawl, pollution, and deforestation has caused population declines or even extinction of many of the world's approximately 2,600 snake species. Furthermore, misconceptions about snakes have made them among the most persecuted of all animals, despite the fact that less than a quarter of all species are venomous and most species are beneficial because they control rodent pests. It has become increasingly urgent, therefore, to develop viable conservation strategies for snakes and to investigate their importance as monitors of ecosystem health and indicators of habitat sustainability. In the first book on snakes written with a focus on conservation, editors Stephen J. Mullin and Richard A. Seigel bring together leading herpetologists to review and synthesize the ecology, conservation, and management of snakes worldwide. These experts report on advances in current research and summarize the primary literature, presenting the most important concepts and techniques in snake ecology and conservation. The common thread of conservation unites the twelve chapters, each of which addresses a major subdiscipline within snake ecology. Applied topics such as methods and modeling and strategies such as captive rearing and translocation are also covered. Each chapter provides an essential framework and indicates specific directions for future research, making this a critical reference for anyone interested in vertebrate conservation generally or for anyone implementing conservation and management policies concerning snake populations.

Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.
