Biogeography And Ecology Of The Pityusic Islands

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.

Isolation, extinction, conservation, biodiversity, hotspots.

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. Not surprisingly, they are widely studied by ecologists, conservationists and evolutionary biologists alike. There is no other recent textbook devoted solely to island biogeography, and a synthesis of the many recent advances is now overdue. This second edition builds on the success and reputation of the first, documenting the recent advances in this exciting field and explaining how islands have been used as natural laboratories in developing and testing ecological and evolutionary theories. In addition, the book describes the main processes of island formation, development and eventual demise, and explains the relevance of island environmental history to island biogeography. The authors demonstrate the huge significance of islands as hotspots of biodiversity, and as places from which disproportionate numbers of species have been extinguished by human action in historical time. Many island species are today threatened with extinction, and this work examines both the chief threats to their persistence and some of the mitigation measures that can be put in play with conservation strategies tailored to islands.

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.
