Book Description
What have we learnt about the Nile since the mid-1970s, the moment when Julian Rzóska decided that the time had come to publish a comprehensive volume about the biology, and the geological and cultural history of that great river? And what changes have meanwhile occurred in the basin? The human popu- tion has more than doubled, especially in Egypt, but also in East Africa. Locally, industrial development has taken place, and the Aswan High Dam was clearly not the last major infrastructure work that was carried out. More dams have been built, and some water diversions, like the Toshka lakes, have created new expanses of water in the middle of the Sahara desert. What are the effects of all this on the ec- ogy and economy of the Basin? That is what the present book sets out to explore, 33 years after the publi- tion of “The Nile: Biology of an Ancient River”. Thirty-seven authors have taken up the challenge, and have written the “new” book. They come from 13 different countries, and 15 among them represent the largest Nilotic states (Egypt, Sudan, Ethiopia, Uganda, and Kenya). Julian Rzóska died in 1984, and most of the - authors of his book have now either disappeared or retired from research. Only Jack Talling and Samir Ghabbour were still available to participate again.

Book Description
Maritime canals dissolve natural barriers to the dispersal of marine organisms, providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.

Book Description
Many authors of this new book were participants at the workshop on diapause in aquatic invertebrates (Pallanza, Italy 2003). This book consists of two major parts: phenomenology of diapause and significance of this adaptation in scientific and practical uses. It combines the theoretical part with the application of knowledge on diapause in the wide spectrum of scientific and applied fields.

Book Description
In view of the massive change in the area of distribution of many world biota across classical biogeographical realms, and of the drastic restructuring of the biotic components of numerous ecosystems, the Scientific Committee on Problems of the Environment (SCOPE) decided at its general Assembly in Ottawa, Canada, in 1982 to launch a project on the 'Ecology of Biological Invasions'. Several regional meetings were subsequently organized within the framework of SCOPE, in order to single out the peculiarities of the invasions that took place in each region, the behaviour of their invasive species and the invasibility of their ecosystems. Most noteworthy among such workshops were one in Australia in August 1984, one concerning North America and Hawaii in October 1984, and one dealing with southern Africa in November 1985. A leitmotiv of these workshops was that most of the invasive species to those regions were emanating from Europe and the Mediterranean Basin, inadvertently or intentionally introduced by man. It was therefore considered as a timely endeavour to organize the next regional meeting in relation to this region. The workshop on 'Biological Invasions in Europe and the Mediterranean Basin' was held in Montpellier, France, 21 to 23 May 1986, thanks to the financial support of SCOPE and of the A.W. Mellon Foundation, and the logistic facilities of the Centre National de la Recherche Scientifique (C.N .R.S.).

Book Description
Planktonic protists both produce and consume most of the primary production in the world ocean. They not only play key roles in the oceans but also represent an astounding amount of diversity: ecological morphological and genetic. However, for most taxa their ecology, morphology, phylogeny and biogeography are either poorly known or appear to be largely unrelated to one another; this hinders our understanding of their biology as well as interpretation of emerging genetic data. Tintinnid ciliates represent a singular exception. Compared to nearly all other groups of planktonic protists, there is a very substantial and relatively detailed literature (both modern and historical) on tintinnids. This volume synthesizes knowledge concerning a wide variety of topics ranging from anatomy and systematics, physiology, behavior, ecology (including ecological roles, predators, parasites, biogeography, and cysts) to fossil history. It will appeal to an audience ranging from advanced undergraduates to researchers in the fields of Oceanography, Marine Biology and Microbial Ecology.

Book Description
This textbook provides a fresh, up-to-date, introduction to biogeography. Examining where different animals and plants live and how they came to be living there it investigates how populations grow, interact and survive. It explores how equilibrium communities are formed, how communities change and looks at the likely shape of communities in the twenty-first century. Stressing the role of ecological, geographical, historical and human factors in fashioning animal and plant distributions, Huggett reveals how life has, and is, adapting to its biological and physical surroundings. The book includes several sections on how human attitudes to nature differ, and how biogeography can affect conservation practice. Huggett tackles many topical and controversial environmental and ethical concerns including: * animal rights * species exploitation * habitat fragmentation * biodiversity * metapopulations Illustrated throughout with informative diagrams and photos, and including chapter summaries, guides to further reading and an extensive glossary of key terms Fundamentals of Biogeography presents an engaging introduction for students.

Fundamentals of Biogeographyoffers a fresh, uptodate, introduction to biogeography, explaining the ecology, geography and history of animals and plants. The book defines and examines populations, communities and ecosystems - examining where different animals and plants live and how they came to be living there, investigating how populations grow, interact and survive. Stressing the role of ecological, geographical, historical and human factors in fashioning animal and plant distributions, Huggett reveals how life has and is adapting to its biological and physical surroundings. The book includes several sections on human attitudes to Nature differ, and how biogeography can affect conservation practice. As well as explaining key concepts and interactions, Huggett tackles many topical and controversial environmental and ethical concerns including: animal rights, species exploitation, habitat fragmentation, biodiversity, metapopulations, patchy landscapes and chaos. Illustrated throughout with informative diagrams and photos, and including chapter summaries, guides to further reading and an extensive glossary of key terms, Fundamentals of Biogeographypresents an engaging introduction for students.
