Download or read book Zoological Collections of Germany written by Lothar A. Beck and published by Springer. This book was released on 2018-02-05 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to the knowledge of up to 250 years of collecting, organizing and preserving animals by generations of scientists. Zoological Collections are a huge resource for modern animal research and should be available for national and international scientists and institutions, as well as prospective public and private customers. Moreover, these collections are an important part of the scientific enterprise, supporting scientific research, human health, public education, and the conservation of biodiversity. Much of what we are beginning to understand about our world, we owe to the collection, preservation, and ongoing study of natural specimens. Properly preserved collections of marine or terrestrial animals are libraries of Earth's history and vital to our ability to learn about our place in its future. The approach employed by the editor involves not only an introduction to the topic, but also an external view on German collections including an assessment of their value in the international and national context, and information on the international and national collection networks. Particular attention is given to new approaches of sorting, preserving and researching in Zoological Collections as well as their neglect and/or threat. In addition, the book provides information on all big Public Research Museums, on important Collections in regional Country and local District Museums, and also on University collections. This is a highly informative and carefully presented book, providing scientific insight for readers with an interest in biodiversity, taxonomy, or evolution, as well as natural history collections at large.

Download or read book Reptilian Lungs written by Steven F. Perry and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph has attempted to bring together morphological and physiological studies of reptilian lungs, to analyze the nature of the resulting correlations, and to risk some speculations regarding the evolution of reptilian lung structure. Central to this work is the morphometric evaluation of the lungs in two species of lizard: "the teju (Tupinambis nigropunctatus Spix) and the savanna monitor (Varanus exanthema ticus [Bosc]) which is presented here for the first time. These two species are similar in body form, and both are diurnally active predators, but their lungs are of basic ally different structural types. The teju possesses relatively small, single-chambered (unicameral) lungs in which the homeycomb-like (faveolar) parenchyma is more or less evenly distributed along their length. In the monitor the lungs are large and many-chambered (multicameral), the individual chambers connecting to an unbranched, intrapulmonary bronchus. The parenchyma is in the form of shallow cubicles (ediculae), which are elaborated on the intercameral septa. The parenchyma is heterogeneously distributed within the lungs, tending to be most concentrated near the intrapulmonary bronchus and the middle third of the lung length. The ventral and caudal portions of these lungs are thin-walled and highly flexible. In both species those portions of the lungs which are most exposed to air convection possess dense capillary nets which almost completely cover both sides of the parenchymal partitions. In more distal regions of the parenchy ma or of the lung, the intercapillary spaces become larger, creating a pseudo-single capillary net.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents perspectives on the past and present state of the understanding of snake origins. It reviews and critiques data and ideas from paleontology and neontology (herpetology), as well as ideas from morphological and molecular phylogenetics. The author reviews the anatomy and morphology of extant snakes. Methods are also critiqued, including those empirical and theoretical methods employed to hypothesize ancestral ecologies for snakes. The modern debate on squamate phylogeny and snake ingroup phylogeny using molecules and morphology is examined critically to provide insights on origins and evolution. Key Features Important major evolutionary transformation in vertebrate evolution Continuing historical debate in vertebrate paleontology Of wide interest to a core audience of paleontologists, herpetologists, and morphologists Author acknowledged as prominent contributor to debate over snake origins Based on remarkable well preserved fossil specimens

Download or read book Tyrannosaurid Paleobiology written by J. Michael Parrish and published by Indiana University Press. This book was released on 2013-07-05 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawn from a 2005 international symposium, these essays explore current tyrannosaurid current research and discoveries regarding Tyrannosaurus rex. The opening of an exhibit focused on “Jane,” a beautifully preserved tyrannosaur collected by the Burpee Museum of Natural History, was the occasion for an international symposium on tyrannosaur paleobiology. This volume, drawn from the symposium, includes studies of the tyrannosaurids Chingkankousaurus fragilis and “Sir William” and the generic status of Nanotyrannus; theropod teeth, pedal proportions, brain size, and craniocervical function; soft tissue reconstruction, including that of “Jane”; paleopathology and tyrannosaurid claws; dating the “Jane” site; and tyrannosaur feeding and hunting strategies. Tyrannosaurid Paleobiology highlights the far ranging and vital state of current tyrannosaurid dinosaur research and discovery. “Despite being discovered over 100 years ago, Tyrannosaurus rex and its kin still inspire researchers to ask fundamental questions about what the best known dinosaur was like as a living, breathing animal. Tyrannosaurid Paleobiology present a series of wide-ranging and innovative studies that cover diverse topics such as how tyrannosaurs attacked and dismembered prey, the shapes and sizes of feet and brains, and what sorts of injuries individuals sustained and lived with. There are also examinations of the diversity of tyrannosaurs, determinations of exactly when different kinds lived and died, and what goes into making a museum exhibit featuring tyrannosaurs. This volume clearly shows that there is much more to the study of dinosaurs than just digging up and cataloguing old bones.” —Donald M. Henderson, Royal Tyrrell Museum of Palaeontology
