Download or read book Woody Plants of Western African Forests written by William Hawthorne and published by Royal Botanic Gardens Kew. This book was released on 2006 with total page 1046 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the identification of all the woody plants (c. 2,250 species in 740 genera) of the forest region of West Africa called 'Upper Guinea', between Togo and Senegal. Upper Guinea is one of the world's most important centres of biodiversity, from the mountain forests of Liberia, Guinea and Sierra Leone, to the lowland evergreen, and semideciduous forests widespread also in Ghana and Ivory Coast. This comprehensively illustrated guide will play a vital supportive role in the challenge of sustainable development within the forest region of West Africa, helping to promote best practice in the management of its plants and forests.

Download or read book California Amphibian and Reptile Species of Special Concern written by Robert C. Thomson and published by Univ of California Press. This book was released on 2016-06-21 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most important hotspots of herpetological biodiversity in the United States, California is home to many endemic amphibians and reptiles found nowhere else on earth. Many of these taxa have unique ecological and morphological specializations, and their management is an important conservation challenge. Increasing climate change impacts, human development, and extreme drought mean many of these species face an ever-greater risk of extinction. California Amphibian and Reptile Species of Special Concern provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California’s most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state’s amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs. Written in nontechnical language, California Amphibian and Reptile Species of Special Concern will be a valuable resource to a broad range of users from resource managers, field biologists, and academic herpetologists to students and recreational naturalists. Published in association with the California Department of Fish and Wildlife.
Download or read book Opisthobranchs from the western Indian Ocean with descriptions of two new species and ten new records Mollusca Gastropoda written by Nathalie Yonow and published by PenSoft Publishers LTD. This book was released on 2012-05-22 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This large work on sea slugs of the Western Indian Ocean is a major contribution to our knowledge of opisthobranch diversity and biogeography.ÿ The western Indian Ocean has long been known as a distinct biogeographical region, and reports of opisthobranchs from the province have been sporadic.ÿ Despite nearly 200 years of study, recent work estimates that there are more than 1000 undescribed species in the whole of the Indo-Pacific region.ÿ There have been considerable developments in the study of many taxonomic groups for the area in the last 50 years, including opisthobranchs, and this paper describes 70 species, of which ten species are recorded from the western Indian Ocean for the first time.ÿ Many phyllidiids and chromodorids seem to have a distribution limited to the western Indian Ocean, whilst there seem to be differences in species richness between coastal areas and island groups.ÿ Further work will shed light on many of these issues.
Download or read book Ancient Animals New Challenges written by Manuel Maldonado and published by Springer. This book was released on 2015-03-21 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the latest advances in sponge science through a concise selection of studies presented at the VIII World Sponge Conference. The collection of articles reflects hot, ongoing debates in molecular research, such as the monophyletic versus paraphyletic nature of the sponge group, or the new awareness on pros and cons of standard barcodes and other markers in sponge taxonomy and phylogeny. It also features articles showing how the new sequencing technologies reveal the functional and phylogenetic complexity of the "microbial universe" associated to sponge tissues. The ecological interactions of sponges, the effects of nutrients and pollutants, the variability in reproductive patterns, and the processes generating genotypic and phenotypic variability in sponge populations are covered in several contributions. Zoogeography, population structure and dynamics are also approached with both traditional and molecular tools. The effect of anthropogenic disturbance on the natural environment finds its place in this volume with papers dealing with metal accumulation and the potential role of sponges as biomonitors. Biodiversity data from unexplored tropical and deep sea areas are presented. We hope readers will enjoy the selection of papers, which we believe represent collectively a significant contribution to our current understanding of sponges.

Download or read book Encyclopedia of Invasive Species 2 volumes written by Susan L. Woodward and published by Bloomsbury Publishing USA. This book was released on 2011-09-22 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume set provides a one-stop resource on invasive plants, animals, fungi, and microorganisms that are threatening native ecosystems, agriculture, economies, and human health in the United States. Kudzu vine and field bindweed. Eurasian collared-doves, Burmese pythons, and black rats. The northern snakehead and the gypsy moth. All of these are examples of invasive species that have taken over or are threatening certain ecosystems—places where these organisms never naturally occurred. This two-volume work contains 168 entries on plants, animals, fungi, and microorganisms that are invasive in the United States, providing a complete examination of the variety of organisms, pathways, distribution patterns, and impacts of non-native species introduced to this country. Encyclopedia of Invasive Species: From Africanized Honey Bees to Zebra Mussels begins with a background essay that illuminates the complexities of dealing with invasive animals and plants. Each entry provides information on the origins and invasion history of the species in question as well as a general description of the biology and ecology of each organism. Impacts—actual and potential, as well as management strategies—are addressed. Every species is depicted via photographs as well as maps that show its place of origin and invaded regions in the United States. This unique work presents fascinating scientific information as well as valuable insights about how seemingly minor events can drastically alter our environment.
