Available in PDF, EPUB and Kindle. Book excerpt: Land bridges are the causeways of biodiversity. When they form, organisms are introduced into a new patchwork of species and habitats, forever altering the ecosystems into which they flow; and when land bridges disappear or fracture, organisms are separated into reproductively isolated populations that can evolve independently. More than this, land bridges play a role in determining global climates through changes to moisture and heat transport and are also essential factors in the development of biogeographic patterns across geographically remote regions. In this book, paleobotanist Alan Graham traces the formation and disruption of key New World land bridges and describes the biotic, climatic, and biogeographic ramifications of these land masses’ changing formations over time. Looking at five land bridges, he explores their present geographic setting and climate, modern vegetation, indigenous peoples (with special attention to their impact on past and present vegetation), and geologic history. From the great Panamanian isthmus to the boreal connections across the North Atlantic and North Pacific Oceans that allowed exchange of organisms between North America, Europe, and Asia, Graham’s sweeping, one-hundred-million-year history offers new insight into the forces that shaped the life and land of the New World.

Download or read book Fossil Horses of South America written by José Luis Prado and published by Springer. This book was released on 2017-04-25 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an update on the phylogeny, systematics and ecology of horses in South America based on data provided over the past three decades. The contemporary South American mammalian communities were shaped by the emergence of the Isthmus of Panama and by the profound climatic oscillations during the Pleistocene. Horses were a conspicuous group of immigrant mammals from North America that arrived in South America during the Pleistocene. This group is represented by 2 genera, Hippidion and Equus, which include small species (Hippidion devillei, H. saldiasi, E. andium and E. insulatus) and large forms (Equus neogeus and H. principale). Both groups arrived in South America via 2 different routes. One model designed to explain this migration indicates that the small forms used the Andes corridor, while larger horses used the eastern route and arrived through some coastal areas. Molecular dating (ancient DNA) suggests that the South American horses separated from the North American taxa (caballines and the New World stilt-legged horse) after 3.6 - 3.2 Ma, consistent with the final formation of the Panamanian Isthmus. Recent studies of stable isotopes in these horses indicate an extensive range of 13C values cover closed woodlands to C4 grasslands. This plasticity agrees with the hypothesis that generalist species and open biome specialist species from North America indicate a positive migration through South America.

Download or read book Current Advances in Scarabaeoidea Research written by Brett Ratcliffe and published by PenSoft Publishers LTD. This book was released on 2010-01-28 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Scarabaeoidea is one of the largest superfamilies in the Coleoptera and includes approximately 2,200 genera and about 32,000 species worldwide. Scarabs have diversified into most habitats, and they are fungivores, herbivores, necrophages, coprophages, saprophages, and carnivores. Some scarabs exhibit various levels of parental care and sociality. Some are myrmecophilous or termitophilous. Many possess extravagant horns, others are able to roll into a compact ball, and still others are highly armored for inquiline life. Some are important agricultural pests that may destroy crops, while others are used in the biological control of dung and dung flies. Scarabaeoids are popular beetles due to their large size, bright colors, and interesting natural histories. Because of the popularity of the group, there exists an erroneous impression that the superfamily is taxonomically well known. However, even with a lengthy history of study, the group is in real need of continuing research. The papers in this volume cover a wide array of research topics on Scarabaeoidea, including evolutionary relationships, character trait evolution, species concepts, descriptions of new taxa, keys for identification, nomenclature, historical biogeography, methods, and basic life history information. These papers are a valuable contribution to our knowledge of scarabaeoids, and they will provide a foundation for future research.

Available in PDF, EPUB and Kindle. Book excerpt: Maritime canals dissolve natural barriers to the dispersal of marine organisms, providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. This book is the first to assess the impacts of the world’s three principal maritime canals – the Kiel, the Panama, the Suez – as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they connect, and in their permeability to invasions.

Download or read book The Great American Biotic Interchange written by Francis G. Stehli and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two rather different elements combine to explain the origin of this volume: one scientific and one personal. The broader of the two is the scientific basis-the time for such a volume had arrived. Geology had made remarkable progress toward an understanding of the phys ical history of the Caribbean Basin for the last 100 million years or so. On the biological side, many new discoveries had elucidated the distributional history of terrestrial orga nisms in and between the two Americas. Geological and biological data had been combined to yield the timing of important events with unprecedented resolution. Clearly, when each of two broad disciplines is making notable advances and when each provides new insights for the other, the rewards of cross-disciplinary contacts increase exponentially. The present volume represents an attempt to bring together a group of geologists, paleontologists and biologists capable of exploiting this opportunity through presentation of an interdisciplinary synthesis of evidence and hypothesis concerning interamerican connections during the Cretaceous and Cenozoic. Advances in plate tectonics form the basis for a modern synthesis and, in the broadest terms, dictate the framework within which the past and present distributions of organisms must be interpreted. Any scientific dis cipline must seek tests of its conclusions from data outside of its own confines.

Download or read book A Guide to the Carnivores of Central America written by Carlos L. de la Rosa and published by University of Texas Press. This book was released on 2010-06-28 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carnivores such as pumas, jaguars, and ocelots have roamed the neotropical forests of Central America for millennia. Enshrined in the myths of the ancient Maya, they still inspire awe in the region's current inhabitants, as well as in the ecotourists and researchers who come to experience Central America's diverse and increasingly endangered natural environment. This book is one of the first field guides dedicated to the carnivores of Central America. It describes the four indigenous families—wild cats, raccoons and their relatives, skunks and their relatives, and wild canids—and their individual species that live in the region. The authors introduce each species by recounting a first-person encounter with it, followed by concise explanations of its taxonomy, scientific name, English and Spanish common names, habitat, natural history, and conservation status. Range maps show the animal's past and current distribution, while Claudia Nocke's black-and-white drawings portray it visually. The concluding chapter looks to the carnivores' future, including threats posed by habitat destruction and other human activities, and describes some current conservation programs. Designed for citizens of and visitors to Central America, as well as specialists, this book offers an excellent introduction to a group of fascinating, threatened, and still imperfectly understood animals.
