Book excerpt: The definitive volume on opossums, a group of ecologically and scientifically important mammals, covering natural history, evolution, behavior, and biogeography. Opossums are the most diverse and ecologically important group of New World marsupials, although only the Virginia opossum is familiar to North American residents. In fact, many species of opossums are found in Neotropical rainforests, savannas, and other habitats, where they are key participants in food webs and other ecological relationships. One species, the short-tail opossum (Monodelphis domestica), has recently become a model organism for biomedical researchers. Eclipsed in the public imagination by their Australian relatives, opossums remained for many years a somewhat obscure group, of interest primarily to taxonomists and students of mammalian reproduction. While thousands of scientific articles have appeared in recent years on opossum systematics, morphology, behavior, physiology, genetics, and ecology, this important but widely scattered literature has never been effectively summarized—until now. In Opossums, the first book-length treatment of these fascinating organisms, recognized authorities Robert S. Voss and Sharon A. Jansa synthesize a wide range of available information about the diversity, comparative biology, and natural history of the opossum. Peering into every biological facet of the lives of these long-neglected mammals, the volume includes • introductory chapters explaining the paleontological and biogeographic context for opossum evolution • an overview of the extant fauna, which includes over 100 species in 18 genera • a section devoted to opossum phenotypes: morphology, physiology, and behavior • detailed information on opossum natural history, including habitats, diets, predators, and parasites • in-depth and novel interpretations of opossums' adaptive radiation in a phylogenetic context Intended for undergraduate biology majors, graduate students, and research professionals, this coherent and original portrait of opossums will be of particular interest to mammalogists, evolutionary biologists, and Neotropical field biologists as well as biomedical researchers working with Monodelphis domestica as a model organism.

Download or read book American and Australasian Marsupials written by Nilton C. Cáceres and published by Springer Nature. This book was released on 2023-06-30 with total page 1648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the evolution, biogeography, systematics, taxonomy, and ecology of New World and Australasian marsupials, greatly expanding the current knowledge base. There are roughly 140 species of New World marsupials, of which the opossum is the best known. Thanks to recent research, there is now an increasing amount of understanding about their evolution, biogeography, systematics, ecology, and conservation in the Americas, especially in South America. There are also some 270 marsupial species in the Australasian region, many of which have been subject to research only in recent years. Based on this information and the authors’ extensive research, this book provides comprehensive insights into the world's marsupials. It will appeal to academics and specialized researchers, students of zoology, paleontology, evolutionary biology, ecology, physiology and conservation as well as interested non-experts.
Book Synopsis Molecular Systematics of Mouse Opossums (Didelphidae, Marmosa) by : Eliécer E. Gutiérrez
Download or read book Molecular Systematics of Mouse Opossums (Didelphidae, Marmosa) written by Eliécer E. Gutiérrez and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genus Marmosa contains 15 currently recognized species, of which nine are referred to the subgenus Marmosa, and six to the subgenus Micoureus. Recent revisionary research based on morphological data, however, suggests that the subgenus Marmosa is more diverse than the currently accepted taxonomy indicates. Herein we report phylogenetic analyses of sequence data from the mitochondrial cytochrome-b gene representing 12 of the 14 morphologically defined taxa recently treated as valid species of Marmosa (Marmosa) in the aforementioned revisionary work. These data provide a basis for testing the monophyly of morphologically defined taxa in the subgenus Marmosa, and they afford the first opportunity to assess phylogenetic relationships among the majority of species currently referred to the genus. Ten of 11 species of Marmosa (Marmosa) represented by multiple sequences in our analyses were recovered as monophyletic. In contrast, our samples of M. mexicana were recovered as two deeply divergent haplogroups that were not consistently associated as sister taxa. Among other results, our analyses support the recognition of M. isthmica and M. simonsi as species distinct from M. robinsoni, and the recognition of M. macrotarsus and M. waterhousei as species distinct from M. murina. The validity of three other species long recognized as distinct (M. rubra, M. tyleriana, and M. xerophila) is also clearly supported by our results. Although cytochrome-b sequence data are not consistently informative about interspecific relationships in this study, we found strong support for several clades, including (1) the subgenus Micoureus; (2) a group comprised of Marmosa macrotarsus, M. murina, M. tyleriana, and M. waterhousei; (3) a group comprised of M. robinsoni and M. xerophila; and (4) a group comprising all of the species in the subgenus Marmosa that occur north and west of the Andes (M. isthmica, M. mexicana, M. robinsoni, M. simonsi, M. xerophila, and M. zeledoni). Our discovery of the latter clade suggests that the Andes may have played a major role in the early diversification of this speciose radiation of small Neotropical marsupials.

Book Synopsis Phylogeography and Systematics of the Slender Mouse Opossum Marmosops (Marsupialia, Didelphidae) by : Meika A. Mustrangi
Download or read book Phylogeography and Systematics of the Slender Mouse Opossum Marmosops (Marsupialia, Didelphidae) written by Meika A. Mustrangi and published by . This book was released on 1997 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph details molecular (DNA sequence) and morphological variation of slender mouse opposums of the genus Marmosops, a diverse but biologically poorly known group of insectivorous marsupials of the neotropical wet forests. Emphasis is placed on taxa of the Atlantic rainforest of coastal Brazil, with comparisons made to those of Amazonia. Lineages of these opossums are quite old, likely dating fromthe late Tertiary, and the acutal number of species in the genus is considerably higher than presently believed. Both of these findings are important to issues of meaasurement and management of biodiversity in threatened ecosystems.
Book Synopsis Species Limits and Phylogenetic Relationships in the Didelphid Marsupial Genus Thylamys Based on Mitochondrial DNA Sequences and Morphology by : Thomas C. Giarla
Download or read book Species Limits and Phylogenetic Relationships in the Didelphid Marsupial Genus Thylamys Based on Mitochondrial DNA Sequences and Morphology written by Thomas C. Giarla and published by . This book was released on 2010 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Species of the didelphid marsupial genus Thylamys, commonly known as fat-tailed mouse opossums, are broadly distributed in the open habitats of central and southern South America. In this report we examine species limits in the genus and infer phylogenetic relationships among Thylamys species using both molecular phylogenetic and morphological methods. We assessed species limits using a broad geographic sample of DNA sequences from the mitochondrial gene cytochrome b in conjunction with morphological character analysis, and we inferred phylogenetic relationships among species using the cytochrome-b dataset in addition to sequences from the mitochondrial genes cytochrome c oxidase subunit II and NADH dehydrogenase 2 for a representative subset of individuals. Based on the results of these analyses, we recognize Xerodelphys (new subgenus) for T. karimii and T. velutinus, and we recognize seven valid species in the nominotypical subgenus. The latter includes T. macrurus, T. pusillus, and two monophyletic species groups: the Elegans Group (T. elegans, T. pallidior, T. tatei) and the Venustus Group (T. sponsorius, T. venustus). Analysis of cytochrome-b sequences additionally reveals deep phylogeographic structuring in three species (T. pallidior, T. pusillus, T. venustus), each of which contains two or three robustly supported allopatric haplogroups. The existence of undescribed Peruvian forms of the Elegans Group is also plausibly indicated. We provide morphological diagnoses of all species recognized as valid in this report, summarize information about geographic distributions, comment on previous misidentifications, and briefly consider historical-biogeographic scenarios with a focus on dispersal events across the Andes.

Book Synopsis Bones, Clones, and Biomes by : Bruce D. Patterson
Download or read book Bones, Clones, and Biomes written by Bruce D. Patterson and published by University of Chicago Press. This book was released on 2012-05-01 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: As explorers and scientists have known for decades, the Neotropics harbor a fantastic array of our planet’s mammalian diversity, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis. This biological bounty can be attributed partly to the striking diversity of Neotropical landscapes and climates and partly to a series of continental connections that permitted intermittent faunal exchanges with Africa, Antarctica, Australia, and North America. Thus, to comprehend the development of modern Neotropical mammal faunas requires not only mastery of the Neotropics’ substantial diversity, but also knowledge of mammalian lineages and landscapes dating back to the Mesozoic. Bones, Clones, and Biomes offers just that—an exploration of the development and relationships of the modern mammal fauna through a series of studies that encompass the last 100 million years and both Central and South America. This work serves as a complement to more taxonomically driven works, providing for readers the long geologic and biogeographic contexts that undergird the abundance and diversity of Neotropical mammals. Rather than documenting diversity or distribution, this collection traverses the patterns that the distributions and relationships across mammal species convey, bringing together for the first time geology, paleobiology, systematics, mammalogy, and biogeography. Of critical importance is the book’s utility for current conservation and management programs, part of a rapidly rising conservation paleobiology initiative.
Book Synopsis Caatinga by : José Maria Cardoso da Silva
Download or read book Caatinga written by José Maria Cardoso da Silva and published by Springer. This book was released on 2018-01-09 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides in-depth information on Caatinga’s geographical boundaries and ecological systems, including plants, insects, fishes, amphibians, reptiles, birds, and mammals. It also discusses the major threats to the region’s socio-ecological systems and includes chapters on climate change and fast and large-scale land-use changes, as well as slow and small-scale changes, also known as chronic human disturbances. Subsequent chapters address sustainable agriculture, conservation systems, and sustainable development. Lastly, the book proposes 10 major actions that could enable the transformation of Caatinga into a place where people and nature can thrive together. “I consider this book an excellent example of how scientists worldwide can mobilize their efforts to propose sound solutions for one of the biggest challenges of modern times, i.e., how to protect the world’s natural ecosystems while improving human well-being. I am sure this book will inspire more research and conservation action in the region and perhaps encourage other groups of scientists to produce similar syntheses about their regions.” Russell Mittermeier, Ph.D. Executive Vice-Chair, Conservation International
Book Synopsis The Timetree of Life by : S. Blair Hedges
Download or read book The Timetree of Life written by S. Blair Hedges and published by OUP Oxford. This book was released on 2009-04-23 with total page 1237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evolutionary history of life includes two primary components: phylogeny and timescale. Phylogeny refers to the branching order (relationships) of species or other taxa within a group and is crucial for understanding the inheritance of traits and for erecting classifications. However, a timescale is equally important because it provides a way to compare phylogeny directly with the evolution of other organisms and with planetary history such as geology, climate, extraterrestrialimpacts, and other features.The Timetree of Life is the first reference book to synthesize the wealth of information relating to the temporal component of phylogenetic trees. In the past, biologists have relied exclusively upon the fossil record to infer an evolutionary timescale. However, recent revolutionary advances in molecular biology have made it possible to not only estimate the relationships of many groups of organisms, but also to estimate their times of divergence with molecular clocks. The routineestimation and utilization of these so-called 'time-trees' could add exciting new dimensions to biology including enhanced opportunities to integrate large molecular data sets with fossil and biogeographic evidence (and thereby foster greater communication between molecular and traditional systematists). Theycould help estimate not only ancestral character states but also evolutionary rates in numerous categories of organismal phenotype; establish more reliable associations between causal historical processes and biological outcomes; develop a universally standardized scheme for biological classifications; and generally promote novel avenues of thought in many arenas of comparative evolutionary biology.This authoritative reference work brings together, for the first time, experts on all major groups of organisms to assemble a timetree of life. The result is a comprehensive resource on evolutionary history which will be an indispensable reference for scientists, educators, and students in the life sciences, earth sciences, and molecular biology. For each major group of organism, a representative is illustrated and a timetree of families and higher taxonomic groups is shown. Basic aspects ofthe evolutionary history of the group, the fossil record, and competing hypotheses of relationships are discussed. Details of the divergence times are presented for each node in the timetree, and primary literature references are included. The book is complemented by an online database(www.timetree.net) which allows researchers to both deposit and retrieve data.

Book Synopsis Seasonally Dry Tropical Forests by : Rodolfo Dirzo
Download or read book Seasonally Dry Tropical Forests written by Rodolfo Dirzo and published by Island Press. This book was released on 2012-09-26 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.
Book Synopsis The Biology of Biodiversity by : M. Kato
Download or read book The Biology of Biodiversity written by M. Kato and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological diversity, or biodiversity, refers to the universal attribute of all living organisms that each individual being is unique - that is, no two organisms are identical. The biology of biodiversity must include all the aspects of evolutionary and ecological sciences analyzing the origin, changes, and maintenance of the di versity of living organisms. Today biodiversity, which benefits human life in vari ous ways, is threatened by the expansion of human activities. Biological research in biodiversity contributes not only to understanding biodiversity itself but also to its conservation and utilization. The Biology of Biodiversity was the specialty area of the 1998 International Prize for Biology. The International Prize for Biology was established in 1985 in commemoration of the sixty-year reign of the Emperor Showa and his longtime devotion to biological research. The 1998 Prize was awarded to Professor Otto Thomas Solbrig, Harvard University, one of the authors of this book. In conjunction with the awarding of the International Prize for Biology, the 14th International Symposium with the theme of The Biology of Biodiversity was held in Hayama on the 9th and 10th of December 1998, with financial support by an international symposium grant from the Ministry of Education, Science, Sports and Culture of Japan. The invited speakers were chosen so as to cover four basic aspects of biodiversity: species diversity and phylogeny, ecological biodiversity, development and evolution, and genetic diversity of living organisms including human beings.
