Book Synopsis Taxonomic Revision and Phylogenetic Analysis of the Flightless Mancallinae (Aves, Pan-Alcidae) by : N. Adam Smith
Download or read book Taxonomic Revision and Phylogenetic Analysis of the Flightless Mancallinae (Aves, Pan-Alcidae) written by N. Adam Smith and published by PenSoft Publishers LTD. This book was released on 2011-04-20 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The flightless Mancallinae (Aves, Pan-Alcidae) from the Pacific Ocean are represented by one of the richest fossil records among Charadriiformes. A detailed review of previously published and previously undescribed fossils referred to Mancallinae resulted in taxonomic revision of the clade and the identification of three new species from the Miocene and Pliocene of California, USA. This monograph includes descriptions of new Mancallinae species and provides the first species-level phylogenetic hypothesis of Mancallinae relationships. Phylogenetic hypotheses were generated through the combined analysis of molecular sequence data and newly identified morphological character data for extant and extinct charadriiforms. The results of the combined phylogenetic analysis places hypotheses regarding the ethology and morphological convergence of Mancallinae to other flightless wing-propelled divers in phylogenetic context and facilitates comparisons between alcid paleodiversity and paleoclimatic events that have been hypothesized as drivers of alcid evolution.
Download or read book Avian Evolution written by Gerald Mayr and published by John Wiley & Sons. This book was released on 2016-10-31 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the evolutionary history of birds has much improved in recent decades. Fossils from critical time periods are being described at unprecedented rates and modern phylogenetic analyses have provided a framework for the interrelationships of the extant groups. This book gives an overview of the avian fossil record and its paleobiological significance, and it is the only up-to-date textbook that covers both Mesozoic and more modern-type Cenozoic birds in some detail. The reader is introduced to key features of basal avians and the morphological transformations that have occurred in the evolution towards modern birds. An account of the Cenozoic fossil record sheds light on the biogeographic history of the extant avian groups and discusses fossils in the context of current phylogenetic hypotheses. This review of the evolutionary history of birds not only addresses students and established researchers, but it may also be a useful source of information for anyone else with an interest in the evolution of birds and a moderate background in biology and geology.
Book Synopsis Paleogene Fossil Birds by : Gerald Mayr
Download or read book Paleogene Fossil Birds written by Gerald Mayr and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present book the Paleogene fossil record of birds is detailed for the first time on a worldwide scale. I have developed the idea for such a project for several years, and think that it is an appropriate moment to present a summary of our c- rent knowledge of the early evolution of modern birds. Meanwhile not only is there a confusing diversity of fossil taxa, but also significant progress has been made concerning an understanding of the higher-level phylogeny of extant birds. Hypotheses which were not considered even a decade ago are now well supported by independent analyses of different data. In several cases these group together morphologically very different avian groups and allow a better understanding of the mosaic character distribution found in Paleogene fossil birds. The book aims at bringing some of this information together, and many of the following data are based on first-hand examination of fossil specimens.
Book Synopsis Extinction and Phylogeny by : Michael J. Novacek
Download or read book Extinction and Phylogeny written by Michael J. Novacek and published by Columbia University Press. This book was released on 1992 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 99% of all life that has ever existed on this planet is extinct. Moreover, human acceleration of the extinction of species has created a crisis in biodiversity. How can the history of past life be retreived? How does this history bear on our understanding of the organization and evolution of present-day species? These questions are addressed in extinction and phylogeny.
Book Synopsis Great Auk Islands; a field biologist in the Arctic by : Tim Birkhead
Download or read book Great Auk Islands; a field biologist in the Arctic written by Tim Birkhead and published by A&C Black. This book was released on 2010-10-30 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of the author's research expeditions in the Canadian Arctic, this book is for professional and amateur ornithologists, students in ecology and animal behaviour. The Arctic is one of the world's last great wildernesses: a place of outstanding beauty, history and extraordinary wildlife in which seabirds form an important component of a rich, marine environment. Like many other remote regions, it is under threat from human activities, but to protect it we need to understand it. That understanding can come only through scientific research and the central threat of this book is to examine how such research is actually done. It describes the business of conducting biological studies on seabirds in remote parts of eastern Canada. Several themes are engagingly interwoven: the sheer beauty of the Arctic environment, the intriguing biology of its wildlife, and the discovery and exploitation of enormous seabird colonies, including the destruction of the Great Auk. Tim Birkhead describes in personal detail the different facets of research and brings to life both the difficulties and the excitement of working in the Arctic. What is it like setting up a camp for four months on a remote and uninhabited island not far from the North Pole? How does it feel to commute daily by inflatable boat amidst icebergs to study-areas located on towering cliffs, set between ice-blue glaciers? What do you do when a Polar bear decides that you have invaded its Arctic home? Why are the seabird colonies in the high Arctic so enormous? What do we know about lifestyle of the extinct Great Auk? In 1992 Canada's legendary cod fishery was finally destroyed - what are the consequences of this for other wildlife? These are just a few of the questions dealt with in this book. Our future as a species depends upon science and the understanding it brings of the world we live in. The work of scientists often appears obscure, but in this book, Tim Birkhead has used his experience of seven summers in the Arctic to write an accessible and straightforward account of how research is actually done in the field. The text is enriched by David Quinn's illustrations, and by numerous photographs in both black and white, and colour.

Book Synopsis Why Birds Matter by : Çagan H. Sekercioglu
Download or read book Why Birds Matter written by Çagan H. Sekercioglu and published by University of Chicago Press. This book was released on 2016-08-24 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over one hundred years, ornithologists and amateur birders have jointly campaigned for the conservation of bird species, documenting not only birds’ beauty and extraordinary diversity, but also their importance to ecosystems worldwide. But while these avian enthusiasts have noted that birds eat fruit, carrion, and pests; spread seed and fertilizer; and pollinate plants, among other services, they have rarely asked what birds are worth in economic terms. In Why Birds Matter, an international collection of ornithologists, botanists, ecologists, conservation biologists, and environmental economists seeks to quantify avian ecosystem services—the myriad benefits that birds provide to humans. The first book to approach ecosystem services from an ornithological perspective, Why Birds Matter asks what economic value we can ascribe to those services, if any, and how this value should inform conservation. Chapters explore the role of birds in such important ecological dynamics as scavenging, nutrient cycling, food chains, and plant-animal interactions—all seen through the lens of human well-being—to show that quantifying avian ecosystem services is crucial when formulating contemporary conservation strategies. Both elucidating challenges and providing examples of specific ecosystem valuations and guidance for calculation, the contributors propose that in order to advance avian conservation, we need to appeal not only to hearts and minds, but also to wallets.

Download or read book Aeroecology written by Phillip B. Chilson and published by Springer. This book was released on 2018-04-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book consists of a diverse collection of chapters that seeks to broaden our fundamental understanding of the ecological function and biological importance of the Earth’s lower atmosphere, which provides a huge living space for billions of animals moving within and across continents. Their migration, dispersal and foraging activities connect water and land habitats within and across continents. Drawing upon the wide-ranging experience of the authors, the book takes an inherently interdisciplinary approach that serves to introduce the reader to the topic of aeroecology, frame some of the basic biological questions that can be addressed within the context of aeroecology, and highlight several existing and emerging technologies that are being used to promote aeroecological studies. The book begins with several background chapters, that provide introduction into such topics as atmospheric science, the concept of the habitat, animal physiology, and methods of navigation. It then continues with a broad discussion of observational methods available to and used by aeroecologists. Finally, several targeted examples of aeroecological studies are presented. Following the development of the chapters, the reader is provided with a unifying framework for investigating how the dynamic properties of meteorological conditions at local, regional, and global scales affect the organisms that depend on the air for foraging and movement. Material presented in the book should be of interest to anyone wishing to gain a comprehensive understanding of the aerosphere itself and the myriad airborne organisms that inhabit and depend upon this environment for their existence. The material should be accessible to a diverse set of readers at all stages of training and across a range of research expertise.
Book Synopsis Bird Species by : Dieter Thomas Tietze
Download or read book Bird Species written by Dieter Thomas Tietze and published by Springer. This book was released on 2018-11-19 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.
