Book Description
A molecular approach was taken to differentiate morphologically homogeneous species within the Simulium jenningsi species group (SJG). This group of Nearctic black flies consisting of 22 recognized species has its highest diversity in the southeastern United States. No other group of black flies in this region is more ubiquitous or pestiferous. Female black flies in this group are nearly isomorphic, which complicates identification, elucidation of host specificity and pest status, and directed control of through application of Bti in the appropriate natal streams. Among SJG species, only S. luggeri Nicholson & Mickel, S. jenningsi Malloch, and S. penobscotense Snoddy & Bauer have well documented medical and veterinary importance. However, in the Deep South these three species are uncommon or not present (penobscotense), so other group species must be to blame for causing human discomfort. The objective of this study was to use sequences from the nuclear gene speckle (IKappaB kinase complex) for identification of and phylogenetic resolution among SJG species. The ultimate application of the fruits of this project is enabling the identification of pest females. Several positively identified individuals (mostly pupae) of each species were used as standards against which unknowns can eventually be compared. Parsimony and Bayesian phylogenetic analyses were conducted. The data obtained permitted identification of all morphospecies except S. nyssa Stone & Snoddy, S. infenestrum Moulton & Adler, and S. penobscotense. It could not resolve relationships within the fibrinflatum (fibrinflatum Twinn, notiale Stone & Snoddy, snowi Stone & Snoddy, and underhilli Stone & Snoddy) and taxodium (taxodium Snoddy, lakei Snoddy, chlorum Moulton & Adler, confusum Moulton & Adler) complexes. A large degree of polymorphism was observed within several species, possibly indicative of introgression or highly polymorphic antecedent species.

Book Description
In this age of increased fundamental and applied research on biodiversity, no single volume was as yet devoted to the various temporal and spatial aspects of aquatic biodiversity. The present book is published in honour of Professor Henri Dumont (Ghent, Belgium) at the occasion of his retirement as Editor-in-Chief of Hydrobiologia. The volume presents a selection of contributions on aquatic biodiversity, written by colleagues from the editorial board, fellow editors of aquatic journals and former students and collaborators. Contributions deal with a wide spectrum of topics related to aquatic biodiversity and cover fields such as actual- and palaeolimnology, taxonomy, and fundamental and applied limnology. Even reconnaissance chapters on management and cultural impact of water bodies are included. The book combines state-of-the-art contributions in aquatic sciences.

Book Description
The majority of undergraduate texts in invertebrate zoology (of which there are many) fall into one of two categories. They either offer a systematic treatment of groups of animals phylum by phylum, or adopt a functional approach to the various anatomical and physiological systems of the better known species. The Invertebrates is the first and only textbook to integrate both approaches and thus meet the modern teaching needs of the subject. This is the only invertebrate textbook to integrate systematics and functional approaches. The molecular systematics sections have been completely updated for the new edition. Strong evolutionary theme which reflects the importance of molecular techniques throughout. Distills the essential characteristics of each invertebrate group and lists diagnostic features to allow comparisons between phyla. New phyla have been added for the new edition. Stresses comparisons in physiology, reproduction and development. Improved layout and illustration quality. Second edition has sold 14000 copies. Nature of the first edition: 'Students will like this book. It deserves to succeed.'

Book Description
Aquatic ecology is the study of various interactions of flora, fauna and ecological characteristics in an aquatic environment. It comprises the study of marine as well as freshwater ecosystems. This book presents complex subject of aquatic ecology in the most comprehensible and easy to understand language. It aims to present researches that have transformed this discipline and added its advancement. This book on aquatic ecology and biodiversity consist of topics dealing with preservation of ecologically significant areas, damage caused due to natural calamities and fishing activities, etc. The book would prove fruitful for researchers and students in the area of sustainable agriculture, natural habitat management and wildlife habitats.

Book Description
This book deals with the ecology of rivers and streams in the Oriental Region, and describes the composition of their unique fauna - especially the diverse array of animals which live on and among the bottom sediments. Dichotomous keys are provided as an aid to the identification of these animals, and the book is illustrated by over 100 pages of line drawings and maps. Special emphasis is given to the impact of human activities on streams and rivers, and the book concludes with a discussion of conservation and management options for these endangered habitats.

Book Description
In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.

Book Description
J. I. Furtado and S. Mori This volume, 'Tasek Bera, the ecology of a tropical freshwater swamp', is a monograph based on research at Tasek Bera, under the auspices of the International Biological Programme (lBP) involving Japanese and Malaysian scientists under the sponsorship of the Malaysian National Committee for the IBP (MNC-IBP) which was initiated by the Malaysian Scientific Association (MSA). This collaboration was initiated by one of us (S. Mori) in 1966 at the Scientific Committee for Freshwater Productivity (PF) of the International Biological Programme (SCIBP) of the International Council of Scientific Unions (lCSU). It involved discussions between the Japanese National Com mittee for the IBP (JIBP) and the Malaysian National Committee for the IBP (MNC-IBP) and their respe
