Some animals are not native to the ranges in which they now live. If they create issues that might cause problems or hinder native species, they are referred to as invasive species. This is the case with Wild Hogs and Peccaries. These feral pigs successfully survive and increase their population by 20% each year and currently at 9 million in the USA. As mammals with the most complex behaviors, they leave behind a disrupted environment that can take many years to recover.

Wild pigs inhabit vast areas in Europe, Southern Asia and Africa, and have been introduced in North and South America, while feral pigs are widespread in Australia and New Zealand. Many wild pig species are threatened with extinction, but Eurasian wild boar populations, however, are increasing in many regions. Covering all wild pig and peccary species, the Suidae and Tayassuidae families, this comprehensive review presents new information about the evolution, taxonomy and domestication of wild pigs and peccaries alongside novel case studies on conservation activities and management. One hundred leading experts from twenty five countries synthesise understanding of this group of species; discussing current research, and gaps in the knowledge of researchers, conservation biologists, zoologists, wildlife managers and students. This beautifully illustrated reference includes the long history of interactions between wild pigs and humans, the benefits some species have brought us and their role and impact on natural ecosystems.

Some people enjoy fishing. Others LOVE fishing. Lots of people like eating North American catfish. But there is more than the frying pan to these fascinating fish. Catfish about in most places where there are ample water and food. Some are relatively small, and yet some are humongous. The reason catfish can grow extremely large is that they never stop growing. The older the fish, the larger it becomes. In this issue, you will learn about how catfish communicate, regulate their body temperature, and how they can position themselves in different thermoclines in the lake or ocean. Finally, we will come to know and appreciate this fantastic boney fish that lives in our freshwater and marine ecosystems.

With an estimated population of at least 500,000 distributed across nineteen states, the wild-living pig (Sus scrofa) is the most abundant free-ranging introduced ungulate in the United States. Until now, however, little has been known about the wild pig on a national scale, despite its abundance and significance as both a pest and a game animal. Whereas previous studies have been regional in scope, Wild Pigs in the United States is the most comprehensive work available on wild pig history, current status, comparative morphology, and other subjects important to the species' management and control. The information in this volume relates to the country's three prevalent wild pig types: the introduced Eurasian wild boar, the feral (once domestic, now wild) hog, and hybrids of the two. The first section of the book presents a history of wild pigs in this country-their origins; when, where, and by whom they were first introduced; and their subsequent dispersal. John J. Mayer and I. Lehr Brisbin, Jr. then develop specific criteria, based on taxonomic principles, for differentiating between the wild pig types. Employing numerous illustrations, graphs, and tables, they analyze and compare morphometric and discrete characters of the skull, external body dimensions and proportions, coat colorations patterns, and hair structure and form. A report on the status of wild pig populations in the United States (as of 1991) completes the volume. To profile the present ranges, habitats, and morphotypic makeups of wild pigs, the authors conducted two national surveys--in 1981 and 1988--among private individuals and federal and state personnel. Their report is also based on other recent wild pig studies and additional information from survey respondents. The book's reference section is particularly valuable, for its lists all sources consulted as well as the names and addresses of authorities the authors interviewed or with whom they corresponded. Aided by the book's wealth of current data, biologists and wildlife managers can make informed decisions about such issues as state versus private ownership of wild pig populations and the status of wild pigs as pests or game animals. In addition, hunters and sportsmen, zoologists, and even specialized historians and archaeologists will find Wild Pigs in the United States useful and informative.

Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

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.
