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.

The first comprehensive treatment of North American rodents of conservation concern. This action plan summarizes the rodent fauna of North America and provides available information on every rodent taxon that has been considered to be of conservation concern by state, provincial and private conservation agencies and regional experts. It is hoped that the survey provided in this action plan will serve as a common ground for all these parties in drawing up conservation strategies for rodents.

This volume contains 82 chapters that provide detail and understanding to the fields of human and medical virology. The first section describes general features of common human viruses with specialized chapters related to HIV/AIDS. The volume goes on to describe exotic virus infections, including one now eradicated virus (smallpox) and some now controlled by vaccination such as yellow fever. Concepts of medical virology are further developed with entries on viruses associated with oncogenesis and selections of interest to medical virology. The most comprehensive single-volume source providing an overview of virology issues related to human and medical applications Bridges the gap between basic undergraduate texts and specialized reviews Concise and general overviews of important topics within the field will help in preparation of lectures, writing reports, or drafting grant applications

Showcases the vibrant ecosystems sustained by South Carolina's waterways; Sure to foster a greater appreciation for South Carolina's waterways as well as a desire to conserve them for future generations, The South Carolina Aquarium Guide to Aquatic Habitats of South Carolina introduces readers, hikers, boaters, reachers, and students to the remarkable beauty and complexity of the state's wetlands. With almost a quarter of its acreage covered by water, South Carolina is a small state distinguished by biological diversity and an extensive range of habitats. This guide, written in an engaging and easy-to-read style by two experienced naturalists, tells the story of water's inexorable movement from mountains to coast, and of the abundant plant and animal species that benefit from its many stops, starts, and backtrackings along the way. Underscoring the fact that the state's streams, rivers, lakes, swamps, marshes and estuaries form a single, interrelated system, Pete Laurie and David Chamberlain explore the particular wetland habitats in each of South Carolina's five physiographic regions. They describe habitats as varied as waterfalls, blackwater swamps, and tidal creeks and as distin
