Book Description
A large part of this book is dedicated to the geology of the Pityusic Archipelago, followed by contributions on climate and geography. Funguses, mosses and leeks are the subjects of taxonomical botany, and a further paper deals with the vegetation of the islands. Another large part of this book is concerned with zoology: faunal lists on fleas, bees, wasps, ants, butterflies, beetles, snails, amphibians and reptiles, birds and mammals, the latter with their epi- and endofaunas as well as their subfossil remains are presented in 13 different papers. Three of them deal with the special problems of isolation and evolution of new races on rocks and small islets: tenebrionid beetles, lizards and terrestrial snails. Man, as an important factor in the Pityusic Islands, is dealt with in six contributions: prehistory, which means pre-Phoenician and which is treated for the first time, folk architecture, the 'endemic' dialect of the Catalonian language, exploitation of some natural resources and finally the problems of inbreeding and related matters on Formentera. The book closes with an outlook on the present state of the Pityusic nature and tries to show ways of conserving all important parts of the archipelago, so that 'our' two islands may preserve some of their typical vegetation, plants and animals and, thus, of their character.

Book Description
Biogeography was stuck in a "natural history phase" dominated by the collection of data, the young Princeton biologists Robert H. MacArthur and Edward O. Wilson argued in 1967. In this book, the authors developed a general theory to explain the facts of island biogeography. The theory builds on the first principles of population ecology and genetics to explain how distance and area combine to regulate the balance between immigration and extinction in island populations. The authors then test the theory against data. The Theory of Island Biogeography was never intended as the last word on the subject. Instead, MacArthur and Wilson sought to stimulate new forms of theoretical and empirical studies, which will lead in turn to a stronger general theory. Even a third of a century since its publication, the book continues to serve that purpose well. From popular books like David Quammen's Song of the Dodo to arguments in the professional literature, The Theory of Island Biogeography remains at the center of discussions about the geographic distribution of species. In a new preface, Edward O. Wilson reviews the origins and consequences of this classic book.

Book Description
Island biogeography is the study of the distribution and dynamics of species in island environments. Due to their isolation from more widespread continental species, islands are ideal places for unique species to evolve, but they are also places of concentrated extinction. Consequently, theyare widely studied by ecologists, evolutionary biologists, and conservationists.This accessible textbook builds on the success and reputation of its predecessors, documenting the recent advances in this exciting field and explaining how islands have contributed to both theory development and testing. In addition, the book describes the main processes of island formation,subsequent dynamics, and eventual demise, explaining the relevance of island environmental history to island biogeography. The authors demonstrate the significance of islands as hotspots of biodiversity and of prehistoric and historic anthropogenic extinction. Since island species continue tofeature disproportionally in the lists of threatened species today, the book examines both the chief threats to their persistence and some of the mitigation measures that can be put in play, with conservation strategies specifically tailored to islands.

Book Description
remnants of gene pools of these species. Badghyz Natural Reserve, established in 1941, became a refuge for the last existing population of the Turkmen onager (Equus hemionus onager) and a unique pistachio woodland. A new generation oflocal Turkmen scientists, many of whom were trained by the Russian researchers in the graduate schools of Moscow and Leningrad arose from the 1930s through the 1950s. The Turkmen Academy of Sciences and its journal, Proceedings (including the monthly biological series), served to record the results of diverse biological studies in the republic. While basic science in the Middle Asian republics rather gained from the Russian "colonial" influence, natural resources, in contrast, were severely damaged by the Soviet way of handling the economy and social issues. Severe environmental problems have been inherited by the now independent Turkmenistan, including overgrazed desert pastures, deforested mountains, depleted water resources, accumulated pesticides in cotton fields, declining populations of endangered species of animals and plants, and - worst of al- progressing, human-caused desertification (Kharin this volume). In order to approach a solution to these problems, scientists and officials in the republic will need the close attention and help of the international scientific community.

Book Description
Lough Neagh is the largest lake in the British Isles. It covers an area of 383 km2 being 30 km along its longest axis. From pre-historic times the lake and its rivers influenced the settlements of man in the role of a fishery and communication link with the interior of Ireland. Ireland's first canal, completed in 1787, linked the small but significant coal deposits of Tyrone to Dublin by way of the lough and later the Lagen Canal became an important commercial route to the new city of Belfast. Today, only sand barge transport persists but the lough supports Europe's largest eel fishery and provides commercial salmon, trout and perch catches, besides acting as an important centre for recreational pursuits. Increasingly it has become the major water resource for Northern Ireland supplying much of the demand for the heavily populated Belfast area. Biologically the lough is rich, sustaining enormous invertebrate populations of, for example, chironomids and gammarids alongside the comparatively exotic glacial relict, Mysis relicta. Its bird life makes the lough an area of very special conservation interest as a Ramsar site. The book describes the basic ecology of the lough with particular emphasis on both the interaction of the physical, chemical and biological components and the role of ecology in resource management. Extensive recent researches are set in geological, geographical and historical context and together with palaeolimnological studies of the sediments are used to trace major changes in the ecology of the lough under man's influence, especially in the past 100 years.
