Download or read book Marine Plankton written by Claudia Castellani and published by Oxford University Press. This book was released on 2017 with total page 715 pages. Available in PDF, EPUB and Kindle. Book excerpt: A thorough understanding of planktonic organisms is the first step towards a real appreciation of the diversity, biology, and ecological importance of marine life. A detailed knowledge of their distribution and community composition is particularly important since these organisms are often very delicate and sensitive to change, and can be used as early indicators of environmental change. Natural and man-induced modification of the environment can affect both the distribution and composition of plankton, with important ecological and economic impacts. Marine Plankton provides a practical guide to plankton biology with a large geographic coverage spanning the North Sea to the north-eastern Atlantic coast of the USA and Canada. The book is divided into three sections: an overview of plankton ecology, an assessment of methodology in plankton research covering sampling, preservation, and counting of samples, and a taxonomic guide richly illustrated with detailed line drawings to aid identification. This is an essential reference text suitable for senior undergraduate and graduate students taking courses in marine ecology (particularly useful for fieldwork) as well as for professional marine biologists. It will also be of relevance and use to environmental scientists, conservation biologists, marine resource managers, environmental consultants, and other specialised practitioners.

Download or read book World Checklist of Myrtaceae written by Rafaël Govaerts and published by Royal Botanic Gardens Kew. This book was released on 2008 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Myrtaceae is the ninth largest flowering plant family; it is economically important in the production of timber, gums, essential oils, fruits and spices, and contains many commonly cultivated ornamentals. The family is particularly rich in large genera, often found in some of the world's most threatened ecosystems, where their fruits comprise an important part of the diet of primates and birds. The similarity of Myrtaceae species is high, and its taxonomic and nomenclatural history is complex, resulting in notorious difficulties in basic identification, inventory compilation and floristic treatment. The World Checklist of Myrtaceae is a much needed work that lists all validly published names in the family, providing the source of their publication and indicating which names are currently accepted and which are synonyms. It will be respected as the standard nomenclatural reference for further research into this important family.

Download or read book Amphibian Morphogenesis written by Harold Fox and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book came about as a result of a review I had written earlier on fea tures of cellular changes occurring during anuran metamorphosis. Only a limited treatment of this subject was possible in such a circumscribed work and only specific examples of organic change were dealt with. Thus the sins of omission weighed heavily, for so much information could not be included to provide a more comprehensive and authenticated account of the elaborate, complex, and far-reaching changes that an aquatic larva undergoes to become a terrestrial froglet. A good deal of my working life has been spent investigating amphib ians, especially their larval developmental morphology during metamor phosis, first at the level of light microscopy and in later years by electronmicroscopy. Initially I was particularly concerned with morpho logical homologies of a variety of larval structures, such as the cranial and pharyngeal skeleton and the nerves and musculature, in order to learn more about amphibian phylogeny, for during my pre-and early postgrad uate years G. R. Beer and D. M. S. Watson inspired an undying interest in and respect for vertebrate comparative anatomy. However, it now seems to be that amphibian phylogenetic relationships are best dealt with by the paleontologists, so ably demonstrated by D. M. S. Watson and A. S. Romer and the contemporary enthusiasts in this field like A. L. Panchen, R. L. Carroll, E. Jarvik, and K. S. Thompson among a host of others, particularly in the USA.

Download or read book South Asian Mammals written by Chelmala Srinivasulu and published by Springer Science & Business Media. This book was released on 2012-05-19 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Until now, information on mammals in South Asia has never been brought together on a single platform providing all‐inclusive knowledge on the subject. This book is the most up‐to‐date comprehensive resource on the mammalian diversity of South Asia. It offers information on the diversity, distribution and status of 504 species of terrestrial and aquatic mammals found in Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. This work is unique being the first of its kind that deals with diversity and distribution at the subspecies level. The book is divided in to three chapters. Chapter 1 introduces the subject and takes off from the recent works on mammals at the global level, provides an historical perspective on mammal studies in South Asia and concludes with a note on recent phylogenetic changes at supraordinal levels. Chapter 2 summarizes the information on the diversity of South Asian Mammals, provides analysis by country of mammalian diversity (supported by data in tabular form) dealing with species richness, endemism and possibly occurring species, separate analysis for each country with details on endemic and threatened species, extinct mammals, domestic mammals, and finally the IUCN status of mammals with special emphasis on threatened mammals. Chapter 3 is a comprehensive checklist that provides information on each species, including its scientific name, type details, standardized English name, synonyms, subspecies, distribution and comments on taxonomic status. Country‐wise listings and analysis of species richness with emphasis on subspecies distribution Most of the analysis is supported by data in tabular forms for better understanding Notes on extinct and domesticated mammals as well as their IUCN Red List Status with criteria for such status A very comprehensive bibliography that would help readers track down specific literature ​

Download or read book In Search of Arctic Birds written by Richard Vaughan and published by A&C Black. This book was released on 2010-10-30 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic birds have long held a fascination for Richard Vaughan, whose trips to the region, watching and photographing birds, have provided the raw material for a number of previous publications. Here, he focuses on the historical aspects of Arctic ornithology, bringing to life not only the birds but the activities of those who have lived with them, or explored in search of them. A general introduction to the Arctic and the forces that shape its bird populations and their biology is followed by sections on native peoples, whaling and discovery ships, and the famous ornithologists who have investigated these often inhospitable habitats. Conservation, both of individual species and of habitats, is discussed against the background of threats to the Arctic environment. Since half the Arctic lies in Russia, detailed consideration is naturally given to Arctic bird studies in that country, as well as in North America and Greenland. Purely ornithological interludes look in detail at the Gyrfalcon, Knots, Ross's Gull, geese, divers, Snowy Owls and many more. The book includes practical advice on how to visit the Arctic and where and when to go. Richard Vaughan's own photographs and the drawings of Swedish artist Gunnar Brusewitz do real justice to the beauty of both the environment and its birds.
