Bibliography

A Bibliography of Selected Titles relating mainly to the Natural History of Sri Lanka
An information sharing project initiated by
Gehan de Silva Wijeyeratne 

Introduction and Acknowledgements
This bibliography began as a simple list of titles which I needed to cite regularly. It made sense to have a master list which I could revise and update. I could then use this as a master list from which I could copy and paste relevant titles across to any articles, trip reports or papers I was writing. Requests for information from others and clients grew the list even further. It became clear that it would help others if I consciously expanded the list and made it publicly available.

I suggested to Dr Channa Bambaradeniya that an extended bibliography put together by me and my colleagues could be made available on the web as public document. I would like to thank Dr Channa Bambaradeniya and his colleagues at IUCN who agreed to share with me the bibliography from the 2007 Red List of Threatened Fauna and Flora of Sri Lanka  and The Fauna of Sri Lanka: Status of Taxonomy, Research and Conservation. Many others also agreed to contribute information to this bibliography as it was beneficial to those with an interest in the Natural History of Sri Lanka to have such a document available. The other contributors are listed at the end.

My thanks to Divya Martyn who typed up numerous references and collated information from other contributors.

Some of the references in the bibliography may not relate to Sri Lanka but have been included because they were quoted in works by authors on papers relating to Sri Lanka. Some of these references are those which I had to refer and cite in trip reports on my travels overseas. Some inconsistency is to be expected because it remains an idiosyncratic list and is not intended as a rigorous academic work. It is also not consistent in style as I have ‘marked’ some of the authors references to make it easy for me to search the list. Some of the references have a commentary by me.

Due to the pressures of having to focus on the commercial aspects of our work I have not gone down the route of creating a searchable database. Anyone who wishes to do so, is welcome to use the information in this document.

AROUND THE FORT IN 80 LIVES is the first book in The Merchant City Series and is built on an entirely new concept in travel writing. Merchant cities worldwide are situated at the cross-currents of history and culture, and are subject to constant renewal. Galle Fort is no exception; the loss of some old families to Colombo and overseas means it has never been more important to document their fascinating history for future generations.  This book is a work of passion, and involved going from building to building interviewing people about their family history and current circumstances. Without this documentation, we feel that the buildings would lack real meaning.  As storytellers, we view our task as being as fundamental to the preservation of the Fort, as the architectural restoration that is being carried out by UNESCO and Galle Heritage. In addition to the 80 characters the is an excellent guide at the back of the book to the area including quirky and unusual places to eat and places to see. The opening section covers the Forts history and current situation.

South-East Asia is one of the richest parts of the world in terms of mammals, with species new to science still being described on a regular basis. The first comprehensive guide to the mammals of this region, A Field Guide to the Mammals of South-East Asia covers all the mammals recorded from mainland South-East Asia, from Myanmar through Thailand, Laos, Vietnam and Cambodia and south to Malaysia. A detailed account with key identification characteristics, habitat and behaviour is included for each species, from large mammals such as big cats, the elephant, rhinoceroses and cetaceans, through bears, langurs and badgers, to bats, flying-foxes and rodents. Detailed line drawings amplify details of anatomy and other aspects. Seventy-two magnificent specially commissioned colour plates by top wildlife artists show nearly 500 major species, and thumbnail maps give information on distribution.

A fantastic introduction to the complex inter-relationships and richness of tropical rainforests. I learnt something new on every page I dipped into and could easily relate the content to rainforests in Asia.

Scott, J. & A. (1997). Reprinted 2006. Jonathan Scott's Safari Guide to East African Birds. Revised and updated by Angela Scott. Kensta, Nairobi. 160 pages. Soft Cover. 
A lovely introduction to African birds. Each family has a description on identification, voice, habitat, habits, food and nest with superb photographs illustrating a few common or flagship species. A good way for a beginner to get a handle on East African birds where the number of species runs to around 1,357 species.

Scott, J.  & A. (1997). Reprinted 2003. Jonathan Scott's Safari Guide to East African Animals. Revised and updated by Angela Scott. Kensta, Nairobi. 192 pages. Soft Cover.
An introduction to over 80 species of animals, but mainly the mammals which visitors are likely to see. The species accounts are broad in content and have more detail on the behavioral and ecological aspects which the smaller, compact guides have had to sacrifice. The captioned images also provide further insights into the behaviour of animals. A very good book to have to learn about the commoner African animals.

Stuart, C. & T. (2001). Second Edition. A Photographic Guide to the Mammals of Southern, Central and East Africa. Struik Publishers,Cape Town. 144 pages. ISBN 978-1-86872-621-9.
Covers 142 species of mammals in the familiar New Holland/Struik pocket photographic guide series. The book is rich in information and well illustrated with photographs. The good content together with the compact, portable size will make it a favourite with even experienced mammal watchers. The distribution maps with each species account helps the reader to visually 'eliminate' species when looking to identify one which they are looking at. An ideal book for new comers to African mammals. Every professional safari guide should have one in their kit bag for use with clients.

A good book to complement their pocket photographic guide as some of the species accounts are considerably expanded in this larger format book. Distributions maps and footprints accompany the text and colour photographs.

48 colour plates illustrate 650 species with a further 633 species described under the heading 'allied species'. The subsequent and more comprehensive titles by Helm are probably a better choice for the more serious birder. But the lighter weight Collins still remains a good book somewhere between the compact photographic field guides and the comprehensive field guides.

123 colour plates make up about half of the book with the rest taken by the species descriptions which include the distribution maps. The book covers over 1,100 species. As the colour plates are not spread through the whole book with facing text, each plate has more species than the other field guide by Helm which adopts a text facing plates format. Although each species is therefore drawn smaller, this is not necessarily a bad thing. On the contrary it makes it easier to compare similar species. This is an advantage with species such as weavers, sparrows, sunbirds, etc.
