Download or read book The Taxonomy Systematics and Zoogeography of Hypsibarbus a New Genus of Large Barbs Pisces Cyprinidae from the Rivers of Southeastern Asia written by Walter J. Rainboth and published by Univ of California Press. This book was released on 1996-01-01 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study the author describes Hypsibarbus, a new genus of Asian cyprinid fishes with twelve species, three of them new. A complete set of 45 measurements and 17 counts was taken and analyzed for approximately 250 specimens, including all type material, of more than 1000 specimens encountered, representing most of the major fish collections of the world. The author fully redescribes and illustrates all species in the new genus, and includes keys for their identification. To provide a basis for understanding zoogeographic implications of the phylogeny obtained for Hypsibarbus, the geography and history of the Southeast Asia river basins is discussed in detail.

Available in PDF, EPUB and Kindle. Book excerpt: This field guide covers the major resource groups likely to be encountered in the fisheries of the Cambodian Mekong. These groups include sharks, batoid fishes and bony fishes. The introduction outlines the geographical, environmental and ecological factors influencing fisheries, and the basic components of the fisheries of the Cambodian Mekong. As an aid to identification to higher taxonomic levels, a pictorial index to families and an illustrated guide to orders and families are included. Each species account provides scientific nomenclature, FAO names in English, local names, sizes, notes on fisheries, habitat and biology, and one or more illustrations. The guide is fully indexed and a list of related literature is appended. Finally, 27 colour plates are presented.

Download or read book Biodiversity Hotspot of the Western Ghats and Sri Lanka written by T. Pullaiah and published by CRC Press. This book was released on 2024-02-20 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the first volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that were designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. This first volume in the series focuses on the Western Ghats and Sri Lanka, construed as forming a community of species because of their shared biogeographical history. The volume explores the diversity and conservation efforts of the extraordinarily rich species found here, including plants, many of which are found nowhere else in the world; forests, which face tremendous population pressure and have been dramatically impacted by demands for timber and agricultural land; as well as the hotspot’s diverse mammals, birds, insects, and amphibian species, and more. The volumes in this series will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution.
Download or read book Evolution and Systematics of the Atlantic Tree Rats Genus Phyllomys Rodentia Echimyidae With Description of Two New Species written by Yuri L. R. Leite and published by Univ of California Press. This book was released on 2003-10-20 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the Atlantic Forest tree rats of the genus Phyllomys (Rodentia: Echimyidae), one of the most poorly understood mammal genera inhabiting the coastal rain forests Brazil, the most threatened lowland tropical forest in the world. The author summarizes their distribution, ecology and evolution, using a combination of morphological and molecular analyses, describes two new species, and provides the first systematic revision of the genus, which was originally described in 1839.
Download or read book Evolution in Action written by Matthias Glaubrecht and published by Springer Science & Business Media. This book was released on 2010-07-24 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.
Download or read book Panbiogeography written by Robin C. Craw and published by Oxford University Press. This book was released on 1999-04-15 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeography is a diverse subject, traditionally focusing on the distribution of plants and animals at different taxonomic levels, past and present. Modern biogeography also puts emphasis on the ecological character of the world vegetation types, and on the evolving relationship between humans and their environment. Panbiogeography describes a new synthesis of sciences of plant and animal distribution. The book emphasizes that the geographical patterns of animal and plant distribution contribute directly to the understanding and interpretation of evolutionary history. Geographic location is reintroduced as a critical element of both biogeography and evolutionary biology. The authors present chapters exploring the roles of geology, ecology, evolution in panbiogeographic theory, and introduce new methods, modes of classification, and ways of measuring biodiversity.

Download or read book Freshwater Fishes of the Eastern Himalayas written by Waikhom Vishwanath and published by Academic Press. This book was released on 2021-07-23 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freshwater Fishes of the Eastern Himalayas provides a guide to describe the internationally accepted methods used in the accurate identification of fishes, morphometry, i.e., body proportions, meristics, i.e., counts of countable characters, viz., scales, fin rays, pores, vertebrae etc., characters of bones wherever necessary, special characters, viz., serrations of fin spines, axillary lobes, lobes, color patterns, etc. All the available taxa of the region are covered, making this an essential reference that provides the original description of genera and species. Diagnostic characters in the book can be easily examined by an unaided eye or by a binocular dissecting microscope with transmitted light. - Provides diagnostic characters which are unique for a species or a combination of characters to differentiate each species from its congeners - Includes both verbal and technical aspects, along with color illustrations of the particular part of the fish showing the distinguishing character - Presents diagnostic characters, illustrations or images of the fish and of its parts, showing the unique character and distribution to make it easy for species identification
