Download or read book Tropical Pinnipeds written by Juan J. Alava and published by CRC Press. This book was released on 2017-07-12 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pinnipeds are a fascinating group of marine mammals that play a crucial role as apex predators and sentinels of the functioning and health of marine ecosystems. They are found in the most extreme environments from the Polar regions to the tropics. Pinnipeds are comprised of about 34 species, and of those at least 25% live permanently in tropical zones. This book reviews and updates current research on the biology, marine ecology, bio-monitoring, and conservation of tropical pinniped populations, including their behavior, anthropogenic stressors, and health. It also looks at challenges to be faced for the conservation of tropical pinnipeds, many of which are threatened species.

Download or read book Early Vertebrates written by Philippe Janvier and published by Oxford University Press on Demand. This book was released on 1996 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents our current knowledge of the early vertebrates, which were mainly fish, but included some land vertebrates, and lived 470 to 250 million years ago. It centres on anatomical and phylogenetic questions, but includes information about fossil discovery and preparation, as wellas the analysis of the characteristics from which their relationships may be reconstructed. It addresses critically both old and new problems in the evolution of certain anatomical structures and deals briefly with the animals' way of life, extinction, and former distribution.In addition, the author gives a potted history of the field of vertebrate palaentology and the rise of cladistics, a cmajor methodological revolution in comparative biology. The book is the first in this field to use a cladistic approach. For each major vertebrate group, the reader will find a diagram or relationships, or cladogram, with a selection of characters at each node, and a succinct phlyogenetic classification.

Download or read book Keys to the Nematode Parasites of Vertebrates written by Lynda M. Gibbons and published by CABI. This book was released on 2010 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the Keys have provided a working tool to those within the field and laboratory needing to know "what is this worm?" They have also helped to establish a classification, using associations of characters, that gives real insight into nematode relationships across the group and their lines of evolution. This supplementary volume is designed to complement the original CIH Keys, now reprinted as one volume, with the additional convenience of reordering into superfamily. The supplement includes revised and redescribed taxa and draws attention to new taxa, to generic level, published by many authors after the original Keys were complete. It also identifies the current position of some of the older genera not included in the original Keys.
Download or read book Changing Diversity in Changing Environment written by Oscar Grillo and published by BoD – Books on Demand. This book was released on 2011-11-14 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: As everybody knows, the dynamic interactions between biotic and abiotic factors, as well as the anthropic ones, considerably affect global climate changes and consequently biology, ecology and distribution of life forms of our planet. These important natural events affect all ecosystems, causing important changes on biodiversity. Systematic and phylogenetic studies, biogeographic distribution analysis and evaluations of diversity richness are focal topics of this book written by international experts, some even considering economical effects and future perspectives on the managing and conservation plans.
Download or read book Natural History of Vampire Bats written by Arthur M. Greenhall and published by CRC Press. This book was released on 2018-05-04 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major problem with vampire bats is that whatever information exists is scattered throughout the literature or is not recorded. There are some excellent books on the ecology and biology of bats with very little on vampire bats. This volume fills that gap to provide an in-depth presentation of these unique animals.
Download or read book The Butterflies of Venezuela Nymphalidae I Limenitidinae Apaturinae Charaxinae written by Andrew F. E. Neild and published by Apollo Books. This book was released on 1996 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Part 1 of The Butterflies of Venezuela was a pioneering work of its kind for South America, being the first authoritative volume in a comprehensive faunistic identification series. The series will prove invaluable to all who wish to learn about the remarkable and diverse butterfly fauna of this country and continent. Approximately 1000 species of adult Nympbalidae, Papilionidae, and Pieridae will be treated in the four-part series, equivalent to over one-third of the total Neotropical species in these families. Drawing on over 20 years of personal research in the field, in collections, and in libraries, the detailed accounts for each species encapsulate all that is known about their identification, distribution, behaviour, habitat, and foodplants. The text, which has been written to appeal to specialists and amateurs alike, has been collated from a wealth of published and unpublished sources. It includes extensive commentary on the systematics and nomenclature employed, and provides detailed notes designed to permit the easy identification of every Venezuelan butterfly. General notes on early stages are provided in the introduction to each genus, and where available those of one representative species are fully described. Readers also benefit from the inclusion of an extensive bibliography, which in Part 2 alone comprises almost 800 works fully referenced in the text. Unlike many other guides, the photographic colour plates illustrate every subspecies, generally showing both sexes and wing surfaces for each, plus several representative specimens for highly variable taxa. In addition, a large number of type specimens are reproduced, many of them for the first time. Part 1 cover 276 species including 2 new species and 23 new subspecies. Part 2 treats 196 species incl. 355 subspecies and the colour plates figures over 450 type specimens. 8 new species and 95 new spubspecies are described. 4 neotypes and 10 lectopypes are designated. Part 3 is projected to treat the Papilionidae, Brassolinae, Danainae, and first part of Satyrinae (Pronophilina and Erebiina). Part 4 will cover the family Pieridae and the remaining Satyrinae and Heliconiinae.
