This book was released on 2010-11-30 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: To help visitors, as well as local residents, identify and enjoy the wildlife of Costa Rica, Carrol L. Henderson published Field Guide to the Wildlife of Costa Rica in 2002, and it instantly became the indispensable guide. Now Henderson has created a field guide dedicated to the monkeys, sloths, treefrogs, lizards, crocodiles, and other animals that travelers are most likely to see while exploring the wild lands of Costa Rica. He includes fascinating information on their natural history, ecology, identification, and behavior gleaned from his forty years of travels, studies, and wildlife viewing in Costa Rica, as well as details on where to see these remarkable and beautiful creatures. The mammals, amphibians, and reptiles are illustrated by stunning and colorful photographs—most of which were taken in the wild by Henderson. A detailed and invaluable appendix that identifies many of Costa Rica's best wildlife-watching destinations, lodges, and contact information for trip-planning purposes completes the volume.

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.
