Download or read book Amphibian Biology Volume 11 Part 4 written by Harold Heatwole and published by Pelagic Publishing Ltd. This book was released on 2015-01-02 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series is published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world. This volume, Part 4 in the series, is concerned with Southern Europe (Italy, Malta, Croatia, Slovenia, Serbia, Montenegro, Bosnia and Herzegovina, Macedonia, Albania, Greece, Romania, Hungary, Bulgaria, Turkey, and Cyprus). Each chapter has been written by experts from each country, describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites, threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climatic change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programs, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.

Download or read book Phytoplankton and Equilibrium Concept The Ecology of Steady State Assemblages written by Luigi Naselli-Flores and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume summarises the outcome of the 13th Workshop of the International Association of Phytoplankton Taxonomy and Ecology (IAP) on if, and if so under what conditions phytoplankton assemblages reach equilibrium in natural environments. Quite a number of ecological concepts use terms such as: ecological equilibrium, stability, steady-state, climax, stable state, etc. However, these ecological concepts often have been "translations" of scientific theories developed in physics or chemistry but they almost always lack scientific corroboration, the problem being that often these concepts remain vague and they are not formally defined. Here an attempt to formally recognize what "equilibrium" is in phytoplankton ecology is traced. The book also contains papers by leading scientists on the taxonomy of two selected key groups: cryptomonads and filamentous cyanoprokaryotes. This volume is addressed to all those involved in phytoplankton taxonomy and ecology and in ecology itself.
Download or read book Sustainable Mountain Regions Challenges and Perspectives in Southeastern Europe written by Boian Koulov and published by Springer. This book was released on 2016-02-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Central to this edited volume is the proposition that the mountainous border region of Southeastern Europe needs to become a special target of European Union scale, regional development policy-making. Vivid case studies from eleven Central and Southeast European states present diverse perspectives on this region’s physical geography, economy and demographics and demonstrate the integrative potential of the geographic perspective in mountain research. Europe as a whole has a lot to gain from a “sustainable mountains” policy, especially in Southeast Europe. In their focus on the sustainable development of such areas, the chapters consider regional development policy, ecosystem services assessment, small-scale tourism, and forestry management. This book will be of interest to a wide audience, including academics, students, and practitioners in the fields of geography, ecology, and environmental studies.
Download or read book Phytoplankton and Trophic Gradients written by M. Alvarez-Cobelas and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings deal with the relationship between species composition of freshwater phytoplankton and the trophic gradient. Particular regard is paid to the composite question, what lives where and why? Overview papers report the state of the art and suggest that the trophic spectrum appears to be a probabilistic outcome of several dimensions of variability that impinge upon phytoplankton species selection. Studies on community structure span all latitudes from those of Antarctica to equatorial Brazil, and also include reports on light and nutrient gradients, pH and fish-stock effects on species composition. Seasonal and longterm phytoplankton dynamics in lakes of varying trophic status are also considered. Finally, studies on the taxonomy and autoecology of some groups (e.g. Volvocales, Chrysophytes and Euglenophytes) living at the extremes of the trophic spectrum contribute to our knowledge of this usually neglected phytoplankton. This is the first time that a book covers such a topic, and it will prove an excellent source of information to anyone working on phytoplankton ecology and ecological indicators. Limnologists in general, algologists and the technical staff at water authorities will all benefit by reading this book.

Download or read book Everglades written by Steve Davis and published by CRC Press. This book was released on 1994-01-01 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters. These include the physical driving forces that created and continue to shape the Everglades and patterns and processes of its flora and fauna. The book summarizes recent studies of the region's vegetation, alligators, wading birds, and endangered species such as the snail kite and Florida panther. This referee-reviewed volume is the product of collaboration among 58 international authors from 27 institutional affiliations over nearly five years. The book concludes with a synthesis of system-wide restoration hypotheses, as they apply to the Everglades, that represent the integration and a collective viewpoint from the preceding 30 chapters. Techniques and systems learned here can be applied to ecosystems around the world.

Download or read book International Watercourses Law and Multilateral Environmental Agreements written by Yang Liu and published by BRILL. This book was released on 2024-02-06 with total page 625 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book anchors its arguments in Article 20 of the Watercourses Convention and explores consistencies and inconsistencies in parallel definitions, substantive and procedural obligations and institutional arrangements in IWL, and the Ramsar and Biodiversity Conventions with respect to the protection and preservation of ecosystems of shared inland waters. Dr. Yang Liu argues that the all-around informed and integrated application of IWL and MEAs is essential for the effective protection and preservation of shared inland water ecosystems. However, the degree of cross-fertilization of parallel provisions should be examined on a case-by-case basis in light of the legal analytical framework deployed in this study.

Download or read book IUCN World Heritage Outlook 2014 written by International Union for the Conservation of Nature and Natural Resources (IUCN), World Heritage Programme and published by IUCN. This book was released on 2014-11-30 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural World Heritage sites are internationally recognized as having the highest global conservation significance and include iconic places such as the Serengeti, Great Barrier Reef and the Galapagos Islands. These renowned sites offer crucial insight into the successes and challenges on the frontlines of conservation, but only about half of the natural sites have been regularly monitored through the main monitoring mechanisms of the World Heritage Convention. The IUCN World Heritage Outlook monitoring system, which consists of Conservation Outlook Assessments, complements the Conventions monitoring mechanisms and assesses all World Heritage sites in recognition of their natural "Outstanding Universal Value." This report describes the methodology for the IUCN World Heritage Outlook, reviews the rating system applied and then summarizes the first set of global results. We hope the IUCN World Heritage Outlook will serve as a dynamic new tool to assist in celebrating best practice in World Heritage sites and in helping to address the management challenges in some of the most iconic places on Earth.
