Book Description
Understanding the influence of weather on reproductive events is critical for documenting population demographics and developing appropriate conservation and management strategies. Variations in timing of parturition may be due to changes in the ambient weather which affect the available insect prey density and time reproductive bats must spend torpid. Capture data from 6,767 bats representing 12 species from 28 counties and 360 sites, were used to examine the influence of precipitation, temperature, and latitude on reproduction of bats in Missouri. Although both cool springs and heavy spring precipitation delayed the onset of each reproductive condition, temperature had a greater influence on reproductive timing. Contrary to predictions, high spring precipitation increased reproductive rate and increased synchrony in dates of pregnancy. Differences in onset of reproduction between northern and southern Missouri were not significant, although capture of juveniles ended sooner in northern Missouri. There was a difference in peak nightly activity among bats of different reproductive conditions for all species except Indiana bats, which had a later interspecific activity peak. Red bats had a female biased juvenile sex ratio especially early season, northern bats and gray bats were male biased. Five species had adult male biased sex ratios. Lactating female big brown bats have a lower mass in years with cooler springs. The inevitable escalation of climatic extremes may cause Midwestern bat species to experience environmental stressors in different ways. These data provide regional managers with better tools to address seasonal Indiana bat survey guidelines and potentially inform seasonal mitigation of wind energy facilities based on annual weather variation.

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.

Gray Bat Migration in Missouri

Book Description
Migration is an important and understudied aspect of the life histories of many species, particularly bats. Migration impacts conservation efforts, including efforts to manage the impacts of wildlife disease. The federally endangered gray bat (Myotis grisescens) is a migratory species with documented infections by Pseudogymnoascus destructans, the fungus that causes White-nose Syndrome (WNS). To better understand migration as it might relate to WNS, I quantified the timing and location of gray bat movements in Missouri using acoustic detectors and bat banding. I recorded calls at 4 maternity sites from January to May 2015, and used the R package PVAClone to generate estimates of r and K as measures of arrival rate and an index of population size at the maternity sites respectively. These values were plotted against each cave’s distance from a major hibernaculum to examine whether there was an effect on the arrival of gray bats at a site. Values of r varied between 0.3 and 0.9, and values of K varied between 981 and 3020 among the maternity roosts: estimates were consistent whether considering observation error or not. While bats arrived at the closest maternity colony quicker and in greater numbers, the remaining rates and indices were equivocal with distance. Over 1,000 gray bats were banded and 18 were relocated, revealing previously undocumented connections between gray bat caves across the region. The acoustic methodology used in this thesis could be useful for management officials wanting to monitor the timing of bat migration and site activity, both of which could be affected by WNS. The cave network used by gray bats in Missouri could yield insight into how WNS spreads across cave networks.
