Download or read book A nomenclator of extant and fossil taxa of the Valvatidae Gastropoda Ectobranchia written by Gerhard Haszprunar and published by PenSoft Publishers LTD. This book was released on 2014-02-05 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present catalog provides a compilation of all supra- and (infra-) specific taxa of extant and fossil Valvatidae (Ectobranchia), a group of freshwater operculate snails (Gastropoda, Heterobranchia). Taxa initially described in this family and bsequently classified in other families (in particular Hydrobiidae and Planorbidae, but among others also larval shells of trichopteran insects) as well as names due to errors or misspellings are likewise included. For each taxon the full original reference and the ype locality (and type horizon in fossils) is provided. Remarks on nomenclatorical problems and possible solutions are added if necessary. As a novelty the extensive reference list is as far as possible directly linked to the internet source (digital view or pdf-download) of the respective papers to facilitate future taxonomic research.

Download or read book Vertebrate Paleontology in Utah written by David D. Gillette and published by Utah Geological Survey. This book was released on 1999 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 52 papers in this vary in content from summaries or state-of-knowledge treatments, to detailed contributions that describe new species. Although the distinction is subtle, the title (Vertebrate Paleontology in Utah) indicates the science of paleontology in the state of Utah, rather than the even more ambitious intent if it were given the title “Vertebrate Paleontology of Utah” which would promise an encyclopedic treatment of the subject. The science of vertebrate paleontology in Utah is robust and intense. It has grown prodigiously in the past decade, and promises to continue to grow indefinitely. This research benefits everyone in the state, through Utah’s muse ums and educational institutions, which are the direct beneficiaries.

Download or read book Conservation Biology for All written by Navjot S. Sodhi and published by OUP Oxford. This book was released on 2010-01-08 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation Biology for All provides cutting-edge but basic conservation science to a global readership. A series of authoritative chapters have been written by the top names in conservation biology with the principal aim of disseminating cutting-edge conservation knowledge as widely as possible. Important topics such as balancing conversion and human needs, climate change, conservation planning, designing and analyzing conservation research, ecosystem services, endangered species management, extinctions, fire, habitat loss, and invasive species are covered. Numerous textboxes describing additional relevant material or case studies are also included. The global biodiversity crisis is now unstoppable; what can be saved in the developing world will require an educated constituency in both the developing and developed world. Habitat loss is particularly acute in developing countries, which is of special concern because it tends to be these locations where the greatest species diversity and richest centres of endemism are to be found. Sadly, developing world conservation scientists have found it difficult to access an authoritative textbook, which is particularly ironic since it is these countries where the potential benefits of knowledge application are greatest. There is now an urgent need to educate the next generation of scientists in developing countries, so that they are in a better position to protect their natural resources.
