Book Description
The Indiana bat (Myotis sodalis) has been endangered since 1967 and is the focus of a controversial debate among stakeholders on both public and private lands due to a lack due to a lack of understanding the summer habitat needs of the species. In addition, even less is known about interspecific interactions with other bats and if this could be playing a role in the decline of this species. Our objectives were to estimate the probability of site occupancy for the Indiana bat and the little brown bat (M. lucifugus) from which we could model their summer habitat suitability. We then used our occupancy modeling estimates to determine whether the knowledge of the little brown bat's (M. lucifugus) landscape occupancy patterns improved the fit of Indiana bat occupancy models and vice versa. We used an information theoretic approach to examine a priori hypotheses relative to both probability of detection and site occupancy using an objective model selection criterion to rank the candidate models. For the Indiana bat the quantity of bottomland hardwood forest in a 7 km landscape was the single most significant factor in determining Indiana bat occupancy. For the little brown bat, site combined with distance to water and canopy cover created the top model determining little brown bat occupancy. Combined information of both species' occupancy patterns did not improve the probability of either species' occupancy.

Book Description
Bat species face multiple threats. One such threat, white-nose syndrome (WNS) has drastically reduced many bat populations. Also, habitat loss and fragmentation often forces bats to concentrate in remnant natural areas, or utilize habitats that are not as suitable. Both of these threats, while threaten bats in a general sense, also affect species differentially. The Oak Openings Region of Northwest Ohio is a biodiversity hotspot with a landscape composed of remnant natural areas within a matrix of agriculture and urban areas. This area, which provides crucial summer foraging habitat, has experienced declines in bat activity, shifts in bat assemblages, and some in diversity, in recent years, especially since WNS introduction. To study bats in this diverse landscape, we sampled bats acoustically from May - August 2016. We sampled mobile transects along roads along with stationary sites within the Oak Openings Preserve within the region. We identified calls to species and ran analyses investigating total bat activity, species-specific activity and presence, and bat diversity compared to. We compared bats to environmental, vegetation, road, and landcover parameters. Our results show that certain parameters influence bats as a whole, while others only affect one or a few species. We found that savanna stationary sites had more species-specific activity and bat diversity than forested sites (Rank Sums, p

Book Description
With all new illustrations, color photographs, revised species accounts, updated maps, and a sturdy flexible binding, this new edition of the authoritative guide to bats in Texas will serve as the field guide and all-around reference of choice for amateur naturalists as well as mammalogists, wildlife biologists, and professional conservationists. Texas is home to all four families of bats that occur in the United States, including thirty-three species of these important yet increasingly threatened mammals. Although five species, each represented by a single specimen, may be regarded as vagrants, no other state has a bat fauna more diverse, from the state’s most common species, the Brazilian free-tailed bat, to the rare hairy-legged vampire. The introductory chapter of this new edition of Bats of Texas surveys bats in general—their appearance, distribution, classification, evolution, biology, and life history—and discusses public health and bat conservation. An updated account for each species follows, with pictures by an outstanding nature photographer, distribution maps, and a thorough bibliography. Bats of Texas also features revised and illustrated dichotomous keys accompanied by gracefully detailed line drawings to aid in identification. A list of specimens examined is located at batsoftexas.com.
