This book was released on 2023-07-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expansion and collapse of the geographic range of the Texas rice rat (Oryzomys texensis) in the upper Mississippi River drainage basin at the end of the Holocene was a unique event in North American mammals. In a period of about 4000 years with a point of origin near the American Bottom in Illinois, these small rodents extended their geographic range in a straight-line distance of over 950 km to the west into Nebraska and the same distance to the east into Pennsylvania. Then in less than 400 years this range expansion collapsed back to a point where the northern-most edge of the modern geographic range of these rice rats is in southern Illinois. It is concluded that no single factor led to this geographic range expansion, but it was a complex interplay of changes in Native American populations, culture, foodways, riverine habitats, and climate along with the impact of kleptoparasitism and passive anthropochory. The collapse of the expanded geographic range of Texas rice rats appears to have occurred between AD 1400 and AD 1600, but it did not occur simultaneously throughout the geographic range. This was not an orderly range contraction, but a collapse of populations in place with many local extinction events. These rice rat populations declined beginning with the onset of the Little Ice Age, which brought a colder and wetter climate that caused crop failures resulting from droughts, cold temperatures, or shortened growing seasons. These conditions stressed the dietary reserves of the human populations and thereby the rice rat populations. These conditions, particularly droughts, were harmful to the growing of maize, which served as the primary food resource of the Native Americans and the associated populations of rice rats. It is proposed that the pre-1910 records of rice rat from unusual localities compared to the modern geographic range in southwestern Ohio, Kentucky, and Kansas represent the final extinction events of these Holocene rice rat populations.

Available in PDF, EPUB and Kindle. Book excerpt: From reviews of previous editions: “This is the standard reference about Texas mammals.” —Wildlife Activist “A must for anyone seriously interested in the wildlife of Texas.” —Texas Outdoor Writers Association News “[This book] easily fills the role of both a field guide and a desk reference, and is written in a style that appeals to the professional biologist and amateur naturalist alike. . . . [It] should prove useful to anyone with an interest in the mammal fauna of Texas or the southern Great Plains.” —Prairie Naturalist The Mammals of Texas has been the standard reference since the first edition was coauthored by William B. Davis and Walter P. Taylor in 1947. Revised several times over the succeeding decades, it remains the most authoritative source of information on the mammalian wildlife of Texas, with physical descriptions and life histories for 202 species, abundant photographs and drawings, and distribution maps. In this new edition, David J. Schmidly is joined by one of the most active researchers on Texas mammals, Robert D. Bradley, to provide a thorough update of the taxonomy, distribution, and natural history of all species of wild mammals that inhabit Texas today. Using the most recent advances in molecular biology and in wildlife ecology and management, the authors include the most current information about the scientific nomenclature, taxonomy, and identification of species, while also covering significant advances in natural history and conservation.

This book was released on 2015-07-06 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zoonoses are currently considered as one of the most important threats for public health worldwide. Zoonoses can be defined as any disease or infection that is naturally transmissible from vertebrate or invertebrate animals to humans and vice-versa. Approximately 75% of recently emerging infectious diseases affecting humans are diseases of animal origin; approximately 60% of all human pathogens are zoonotic. All types of potential pathogenic agents, including viruses, parasites, bacteria and fungi, can cause these zoonotic infections. From the wide range of potential vectors of zoonoses, insects are probably those of major significance due to their abundance, high plasticity and adaptability to different kinds of pathogens, high degrees of synanthropism in several groups and difficulties to apply effective programs of population control. Although ticks, flies, cockroaches, bugs and fleas are excellent insects capable to transmit viruses, parasites and bacteria, undoubtedly mosquitoes are the most important disease vectors. Mosquito borne diseases like malaria, dengue, equine encephalitis, West Nile, Mayaro or Chikungunya are zoonoses with increasing incidence in last years in tropical and temperate countries. Vertebrates can also transmit serious zoonoses, highlighting the role of some carnivorous animals in rabies dissemination or the spread of rodent borne diseases in several rural and urban areas. Moreover, the significance of other food borne zoonoses such as taeniasis, trichinellosis or toxoplasmosis may not been underestimated. According to WHO, FAO and OIE guidelines an emerging zoonotic disease can be defined as a zoonosis that is newly recognized or newly evolved, or that has occurred previously but shows an increase of incidence or expansion in geographical, host or vector range. There are many factors that can provoke or accelerate the emergence of zoonoses, such as environmental changes, habitat modifications, variations of human and animal demography, pathogens and vectors anomalous mobilization related with human practices and globalization, deterioration of the strategies of vector control or changes in pathogen genetics. To reduce public health risks from zoonoses is absolutely necessary to acquire an integrative perspective that includes the study of the complexity of interactions among humans, animals and environment in order to be able to fight against these issues of primary interest for human health. In any case, although zoonoses represent significant public health threats, many of them still remain as neglected diseases and consequently are not prioritized by some health international organisms.

Available in PDF, EPUB and Kindle. Book excerpt: In this study I provide a phylogenetic hypothesis for the tribe Oryzomyini that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification. Morphological and molecular data were used for these purposes in combined and separate analyses. Molecular data consisted of partial sequences (1266 bp) from the first exon of the nuclear gene encoding the interphotoreceptor retinoid binding protein (IRBP); the morphological matrix comprised 99 characters, including 16 integumental characters, 32 skull characters, 29 dental characters, 7 postcranial characters, and 10 characters from the phallus and soft-anatomy systems. I present anatomical descriptions for each character, including delineation of different states observed among oryzomyines. Results of the combined analysis were congruent with the IRBP-only dataset for oryzomyine higher-level relationships. Morphological analyses, although showing discrepancies from the combined or IRBP consensus cladograms and with low nodal support values, recovered several clades similar to the combined and IRBP analyses. Systematics of the tribe and the evolution of a few pivotal characters are discussed in light of the proposed phylogeny. Different taxonomic arrangements for species currently included in the genus Oryzomys are suggested. Finally, I evaluate evolutionary and biogeographic hypotheses that are compatible with our current knowledge on oryzomyine relationships.

Available in PDF, EPUB and Kindle. Book excerpt: First comprehensive account of the mammals of the entire southeastern US The southeastern United States is home to a remarkable and diverse mammalian fauna that is a significant part of the region’s rich natural heritage. Mammals of the Southeastern United States presents accounts of 137 species that currently or previously occurred in the Southeast. Although accessible and useful for the generalist, this book provides an up-to-date compilation of basic knowledge about native and nonnative mammals of the region that is suitable for students of all ages and for professional mammalogists and biologists alike. This volume profiles common species like the eastern gray squirrel, the white-tailed deer, and the Virginia opossum, but also includes among its accounts many extant species, such as the jaguar and porcupine, that once occurred in the region; native species, like the Caribbean monk seal, that are now extinct; native species that have been extirpated, or wiped out, from all or part of the region, such as the red wolf, cougar, American bison, and elk; and many introduced species, including the Mexican mouse opossum, common squirrel monkey, and capybara. Each species account includes full-color images of the animal, plates featuring at least three views of its skull, color distribution maps of its approximate geographic range in the Southeast and in North America, and an up-to-date synthesis of several aspects of its biology, including habitat, diet, predators, parasites, diseases, and behaviors. An introductory chapter on conservation summarizes the current status of mammalian populations in the region and provides insight into some of the threats mammals now encounter in the Southeast.
