The Oak Openings Region of Northwest Ohio of Northwest Ohio is an incredibly biodiverse area that is home to many rare and endangered plant and animal species. Furthering our knowledge and understanding on the resident bat species within the region is critical as populations of many species have declined from White-nose Syndrome, habitat loss and fragmentation, and wind energy barotrauma. To further bat-specific research in the region, my thesis research focused on: 1) identifying the relationships between bat activity and diversity and fragmentation features; 2) monitoring trends in activity and richness between forested and savanna sites over time; and 3) developing refined spatially explicit habitat models of bat occupancy using data collected from protected and unprotected habitat and comparing them to models created from strictly protected habitat. Ecological knowledge on bats and their response to features commonly associated with habitat fragmentation is lacking, so I acoustically surveyed thirty roads with Anabat SDII monitors within and outside of protected areas. I utilized logistic regression analysis to examine the relationship between presence/absence and activity of each species with each feature (e.g. proportion of road with overstory) to select candidate variables for multivariate models. I then created candidate multivariate models for each species and selected final models based on parsimony, AIC values, and adjusted R square values. Bats had a differential response to features between species, and park managers must consider the management of roads on a species- specific viewpoint if they plan to focus conservation efforts on bats. For the second part of my research, I surveyed bat relative activity within forest and savanna sites and compared the data to previous monitoring efforts. Within the single year I monitored, savanna sites appeared to host a greater activity for many species and a greater species richness. Between years, savanna sites remained predominantly stable in species composition and activity, but forested sites had declines in activity among certain species and declines in species richness. Results demonstrate a need for further investigation of forest habitat and additional comparisons between savannas and other open habitat to determine their role for bats in the region. For the third part, I developed Maxent species distribution models for seven species of bats that occur in the region and compared them to existing models. I tested previously developed occupancy models' predictive power using new data. Once data were demonstrated to be comparable through model performance, I created new models from a combination of previous (prior to White-nose) and new data (post White-nose). I then tested previous and new models with an independent dataset and compared their performances and areas of predicted presence for each species. The addition of new data refined previous models and offered a species-specific view on the importance of prominent landscape characteristics for probability of presence. The results of this thesis research contribute to our knowledge of bats within the Oak Openings Region and provide tools for adaptive management in fragmented landscapes.

This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.

Every three years a major international conference on bats draws the leading workers in the field to a carefully orchestrated presentation of the research and advances and current state of understanding of bat biology. Bats are the second most populous group of mammalia species, after rodents, and they are probably the most intensively studied group of mammals. Virtually all mammologists and a large proportion of organismic biologists are interested in bats. The earlier two edited books deriving from previous bat research conferences, as well as this one, have been rigorously edited by Tom Kunz and others, with all chapters subjected to peer review. The resulting volumes, published first by Academic Press and most recently by Smithsonian, have sold widely as the definitive synthetic treatments of current scientific understanding of bats.

This book introduces the key stages of niche-based habitat suitability model building, evaluation and prediction required for understanding and predicting future patterns of species and biodiversity. Beginning with the main theory behind ecological niches and species distributions, the book proceeds through all major steps of model building, from conceptualization and model training to model evaluation and spatio-temporal predictions. Extensive examples using R support graduate students and researchers in quantifying ecological niches and predicting species distributions with their own data, and help to address key environmental and conservation problems. Reflecting this highly active field of research, the book incorporates the latest developments from informatics and statistics, as well as using data from remote sources such as satellite imagery. A website at www.unil.ch/hsdm contains the codes and supporting material required to run the examples and teach courses.

Bats are highly charismatic and popular animals that are not only fascinating in their own right, but illustrate most of the topical and important concepts and issues in mammalian biology. This book covers the key aspects of bat biology, including evolution, flight, echolocation, hibernation, reproduction, feeding and roosting ecology, social behaviour, migration, population and community ecology, biogeography, and conservation. This new edition is fully updated and greatly expanded throughout, maintaining the depth and scientific rigour of the first edition. It is written with infectious enthusiasm, and beautifully illustrated with drawings and colour photographs.
