Review of the Genus Cobitis in the Middle East, with the Description of Eight New Species (Teleostei: Cobitidae) by Jörg Freyhof,Esra Baycelebi,Matthias Geiger Pdf

"The diversity of Cobitis in the Middle East is reviewed, resulting in the recognition of 30 species, of which eight are described herein as new. Two species, C. amphilekta and C. kellei, seem to be extinct. Hypotheses on species-level diversity derived from distance and Poisson tree process analyses of DNA barcode data are tested against morphometric and morphological characters including colour patterns. For species pairs separated by small K2P distances in COI sequence data we follow a practitioner-oriented diagnostic species concept, in which we recognise species only if differentiated morphologically (including by colour pattern). For all 30 species we provide diagnoses and identification keys. Keywords: Pisces, Freshwater fish, Taxonomy, Cytochrome oxidase I, Middle East."--Page 3.

Biodiversity, Conservation and Sustainability in Asia by Münir Öztürk,Volkan Altay,Recep Efe Pdf

Of the world’s seven continents, Asia is the largest. Its physical landscapes, political units, and ethnic groups are both wide-ranging and many. Southwest, South and Middle Asia are highly populated regions which, as a whole, cover an extremely large area of varied geography. In total, this domain is unique in its plant diversity and large vegetation zones with different communities and biomes. It is rich in endemics, with specific and intraspecific diversity of fruit trees and medicinal plants, including a number of rare, high value, species. At the same time, much of the land in the region is too dry or too rugged, with many geographical extremes. Overgrazing, oil and mineral extraction, and poaching are the major threats in the area. This two-volume project focuses on the dynamic biodiversity of the region with in-depth analysis on phytosociology, plants, animals and agroecology. There are also chapters that explore new applications as well as approaches to overcome problems associated with climate change. Much of the research and analysis are presented here for the first time. We believe this work is a valuable resource for professionals and researchers working in the fields of plant diversity and vegetation, animal diversity and animal populations, and geo-diversity and sustainable land use, among others. The first volume guides our readers to West Asia and the Caucasus region, while volume two focuses on issues unique to South and Middle Asia.

Freshwater Fish Distribution by Tim M. Berra Pdf

With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

Freshwater Biodiversity by David Dudgeon Pdf

Fresh waters are disproportionately rich in species, and represent global hotspots of biodiversity. However, they are also hotspots of endangerment.

The Biology of Gobies by Robert Patzner,James L. Van Tassell,Marcelo Kovacic,B. G. Kapoor Pdf

Among all vertebrates, gobies are second in diversity only to the teleost family Cyprinidae. The Gobiidae consists of more than 200 genera and nearly 2,000 species and make up the largest family of marine fishes. Gobies account for as much as 50% of the energy flow in coral reef communities. Their small size, ability to adapt to numerous ecological niches and to be bred in aquaria has led to numerous studies both in the field and laboratory. Gobies are found from above the high tide line to depths of over 1,100 m. Some species are found only within caves, others deep inside sponges, and some others climb waterfalls to return to their native streams. They vary reproductively from gonochoric to hermaphrodite, monogamy to polygyny and promiscuity, some have short life spans and reproduce only once while others have longer life spans reproducing one or more times per year. The Biology of Gobies written by over 30 experts from 15 countries summarizes what is known about the systematics, ecology, zoogeography, and general biology of the Gobiiformes. This foundation will provide the basic information necessary for future studies.

Family-group Names of Recent Fishes by Richard Van Der Laan,William N. Eschmeyer,Ronald Fricke Pdf

The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Family names are particularly important because they are among the most widely used of all technical animal names. Apart from using the correct family-group name according to the Code, it is also important to use one unique universal name (with a fixed spelling) to avoid confusion. We have compiled a list of familygroup names for Recent fishes, applied the rules of the Code and, if possible, tried to conserve the names in prevailing recent practice. We list all of the family-group names found to date for Recent fishes (N=2625), together with their author(s) and year of publication. This list can be used in assigning the correct family-group name to a genus or a group of genera. With this publication we contribute to the usage of correct, universal family-group names in the classification of, and for communication about, Recent fishes.

Some Simple Methods for the Assessment of Tropical Fish Stocks by Daniel Pauly,Food and Agriculture Organization of the United Nations Pdf

This selection of methods is based on lecture notes used at a FAO/DANIDA training course held in Mombasa, Kenya, in May-June 1980. The methods presented are: regression and correlation, estimation of growth parameters from length-frequency data, estimation of mortalities (total, natural, fishing mortality) and analysis of catch and effort data. A brief annotated bibliography of tropical fish stock assessment is included.
