Download or read book Futures for the Mediterranean Basin written by Michel Grenon and published by Oxford University Press, USA. This book was released on 1989 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, sponsored by the UN Environmental Programme and carried out by the Blue Plan Regional Activity Centre, reports on the Mediterranean's economic and environmental prospects over the next forty years. The study uses "scenarios" to explore the implications of particular types of change and choices of action, considering the environmental impact of various economic sectors--agriculture, industry, energy, tourism, and transportation--as well as the threat posed by urbanization and development of coastal zones. Featuring a wide range of statistical material presented in tables and maps, this work is unique in making comparisons between so many different countries on a range of ecological and economic variables.
Download or read book Sustainable Tourism written by Gerda K. Priestley and published by . This book was released on 1996 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although widely advocated, sustainable tourism is subject to numerous interpretations -- from environmentally friendly forms of tourism to maintaining the economic viability of tourist activity in a specific place. This book explores various views on sustainable tourism and demonstrates its complexity and diversity, in order to clarify the issues in operational terms. It addresses questions such as: can tourist activity be sustainable economically; can tourism lead to sustainability from an environmental perspective; and what is the role of tourism as a sustainable development strategy? Much of the book consists of a series of European case studies, from the U.K., France, Spain, Italy and Greece. These case studies cover three main themes: recreation and tourism in natural and rural areas; coastal tourism; and islands. The book represents a valuable supplementary text for students of tourism, as well as related disciplines such as geography, economics, environmental management, and local and regional planning and development.
Download or read book Crustaceans and the Biodiversity Crisis written by Frederick R. Schram and published by BRILL. This book was released on 1999 with total page 1048 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important and extensive volume presents part of the Proceedings of the Fourth International Crustacean Congress held in Amsterdam in 1998. As the title implies, 'Crustaceans and the Biodiversity Crisis' was the general, underlying theme of all contributions at the congress. With the turn of the century, someone ought to 'assess the balance' of our natural environment and of the various branches of biology that study its rapidly declining diversity. From the five subthemes covered at the conference, those of (1) "Diversity in Time and Space" (including Systematics, Phylogeny, and Palaeontology), (2b) "Biogeography," (3c) "Larvae," and (4) "Physiology and Biochemistry" (including Molecular Biology and Genetics) are represented in this volume, along with a few contributions from other subthemes (e.g. (2a) "Invasive Crustacea," (3a) "Ecology," (3b) "Behaviour," and (5) "Fisheries and Aquaculture"). The book is primarily meant for scientists working at institutes involved in research on the group (Crustacea: marine, freshwater, or terrestrial) and/or the disciplines covered. Individual carcinologists working on one of the themes discussed in this volume, will find a wealth of interesting and timely contributions, as will other scientists working in marine or freshwater biology or in soil ecology.
Download or read book Catalogue of Geadephaga Coleoptera Adephaga of America north of Mexico written by Yves Bousquet and published by PenSoft Publishers LTD. This book was released on 2012-11-28 with total page 1736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication provides a comprehensive review of the nomenclature and distribution of the Geadephaga of America, north of Mexico. Overall 2439 valid species-group taxa in 208 genera are catalogued along with their synonyms. Besides the usual information pertaining to author(s), date and page of publication, the type locality, location of name-bearing type, first reference establishing each synonym, and etymology for many patronymic names are provided for species-group names. Genus-group names are listed with the author(s), year of publication, page citation, type species with manner of fixation and etymology for most. The geographical distributions of all species-group taxa are briefly summarized and their state and province records are indicated. About 2500 references are listed with publication dates for many in order to assess priority of names.Several new nomenclatural acts are introduced including one new genus-group taxon, one new replacement name, three changes in precedence, five new genus-group synonymies, 65 new species-group synonymies, one new species-group status, and 12 new combinations.The work includes also a discussion of the notable private North American carabid collections, a synopsis of all extant world geadephagan tribes and subfamilies, a brief faunistic assessment of the fauna, a list of North American fossil Geadephaga, a list of North American Geadephaga larvae described or illustrated, a list of species described from specimens mislabeled as from North America, and a list of unavailable names listed from North America.

Download or read book Evolutionary Developmental Biology of Crustacea written by Gerhard Scholtz and published by CRC Press. This book was released on 2003-06-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crustaceans, due to the great diversity of their body organization, segmentation patterns, tagmatization, limb types, larval forms, cleavage, and gastrulation modes, are highly desirable for the study of questions at the interface of evolution and development. Modern interest in evolutionary developmental biology (evo-devo) rests on the molecular genetic approach and a variety of molecular techniques have proven fruitful when performed on crustaceans. Evolutionary Developmental Biology of Crustacea presents a comprehensive treatment of all aspects of the field, beginning with a discussion of the implications of the typological Bauplan and phylum concepts versus historical concepts such as ground pattern and monophylum for the formulation of conceptual questions in evo-devo. Following this, the authors present the results of Hox gene expression in various crustacean taxa, aspects of segment formation at the cellular and genetic levels, the formation of segmental structures such as neurons, ganglia, and limbs, and the role of morphological ontogenetic characters in resolving phylogenetic relationships. By covering so many general aspects of crustacean development, morphology, and evolution, Evolutionary Developmental Biology of Crustacea serves as an indispensable reference for developmental and evolutionary biologists investigating the role of genetics in evolution and development.

Breure and published by PenSoft Publishers LTD. This book was released on 2014-03-21 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family Bulimulidae is a dominant land snail family in the Neotropics, with more than 1000 nominal taxa described. Revisionary work has only partially been done, but many genera need further revisionary work for which a sound taxonomic basis is needed. Type specimens for more than 400 taxa of this family are present in the Natural History Museum, London, U.K., and are documented in this paper. For each taxon the relevant literature is cited, type locality, label, the provenance of the specimens, and the current systematic position; photographs of nearly all type specimens and labels are also provided.
