Book Description
Prepared by two of Missouri's most distinguished conservationists, The Wild Mammals of Missouri has been the definitive guide to mammals of this state for over forty years. Now the University of Missouri Press is pleased to release an updated edition, revised by Elizabeth R. Schwartz, reflecting the changes in Missouri's mammalian fauna and including the latest taxonomic revisions. Maintaining the original's successful format and the language that made the book accessible to both professional and lay readers, the revised edition incorporates throughout new knowledge of the various species of mammals of Missouri. Most notable is the addition of a new resident species, the nine-banded armadillo. Several other taxonomic and distributional changes are reflected and the range maps have been revised to show significant changes. Charles Schwartz's meticulously rendered drawings capture the spirit of his subjects while remaining technically accurate. These drawings range from fully rendered portraits to illustrations of dentition and skulls, tracks, and other identifying characteristics, to vignettes showing the mammals engaged in characteristic behaviors. Also included in this volume are discussions of all biological and ecological aspects of the mammals including distribution and abundance, habitat and home, habits, food, reproduction, adversities faced, and conservation and management concerns. The Schwartzes' lifelong dedication to state and national conservation and their vast biological knowledge are apparent throughout the pages of this attractive reference guide. People of all ages and backgrounds will find The Wild Mammals of Missouri an invaluable guide to the study of Missouri's mammals.

Book Description
Although bats are often thought of as cave dwellers, many species depend on forests for all or part of the year. Of the 45 species of bats in North America, more than half depend on forests, using the bark of trees, tree cavities, or canopy foliage as roosting sites. Over the past two decades it has become increasingly clear that bat conservation and management are strongly linked to the health of forests within their range. Initially driven by concern for endangered species—the Indiana bat, for example—forest ecologists, timber managers, government agencies, and conservation organizations have been altering management plans and silvicultural practices to better accommodate bat species. Bats in Forests presents the work of a variety of experts who address many aspects of the ecology and conservation of bats. The chapter authors describe bat behavior, including the selection of roosts, foraging patterns, and seasonal migration as they relate to forests. They also discuss forest management and its influence on bat habitat. Both public lands and privately owned forests are considered, as well as techniques for monitoring bat populations and activity. The important role bats play in the ecology of forests—from control of insects to nutrient recycling—is revealed by a number of authors. Bat ecologists, bat conservationists, forest ecologists, and forest managers will find in this book an indispensable synthesis of the topics that concern them.

Book Description
The arrival of white-nose syndrome (WNS) has stimulated interest in winter bat activity. Data from a bat activity study in southern Missouri indicated winter gray bat (Myotis grisescens) activity above expected levels. Study objectives were to assess gray bat winter activity including investigating winter feeding, the need for water, whether winter activity occurs at caves and foraging areas, whether gray bats are more active relative to other species, and the effect of climate variables. Acoustic monitoring occurred over three winters at areas in Laclede, Shannon, and Washington counties Missouri, and captures occurred during the 2012-13 winter at Coffin Cave in Laclede County and Bat Cave in Shannon County. I collected temperature, humidity, and barometric pressure data at Coffin Cave and Bat Cave during 2012-13. Gray bats were captured on 24 of 26 attempts, at temperatures as low as -1.7oC. Of 350 bats captured, three provided a feeding fecal sample during mid-winter. Urinating was recorded in >50% of gray bats. Those at Coffin Cave, with available water, urinated earlier than at Bat Cave, with no available water. Acoustic data indicated that gray bats were active all winter at caves and foraging areas and at higher proportions than expected based on cave populations. Activity at Bat Cave correlated with inside humidity and outside temperature, while activity at Coffin Cave did not correlate with climate variables. Activity at Bat Cave was higher than at Coffin Cave. Water needs appear to drive activity.
