Book Description
The Chautauqua Institution is home to one of the largest little brown bat (Myotis lucifugus) populations in New York State. According to many Chautauquans, this population has been declining in the last 10 years. One aspect of this study was to gain information on whether insect availability has changed and could be contributing to a possible decline in the little brown bat population at Chautauqua Institution. A bat colony survey was organized to determine out the locations of colonies for future monitoring of the population. The colony survey response included 34% of the homeowners stating a belief that bats were living in their home. These results are incline with the number of colonies reported in previous studies at Chautauqua Institution. Flying insects were trapped weekly using a Malaise trap in order to gain insight on the insects available to the bats as prey and fecal samples (collected from captured bats) were dissected to allow for identification of insect remains. Data were compared with the past study conducted at Chautauqua during the summers of 1991 & 1992 (Syme 1995) to look for any possible changes. Insect availability suggests agreement between the two studies (order Diptera with highest representation). Diet analysis does not suggest agreement (two most represented orders are different) but may be due to fecal sampling biases. Insect availability and diet analysis from this study were compared and suggest that there is a significant difference (P

Book Description
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.

Book Description
The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

Book Description
This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Book Description
Among living vertebrates bats and birds are unique in their ability to fly, and it is this common feature that sets them apart ecologically from other groups. Bats are in some ways the noctumal equivalents of birds, having evolved and radiated into a diversity of forms to fill many of the same niches. The evolution of flight and echolocation in bats was undoubtedly a prime mover in the diversification of feeding and roosting habits, reproductive strategies, and social behaviors. Bats have successfully colonized almost every continential region on earth (except Antarctica), as weIl as many oceanic islands and archipelagos. They comprise the second largest order of mammals (next to rodents) in number of species and probably exceed all other such groups in overall abundance. Bats exhibit a dietary diversity (including insects, fruits, leaves, flowers, nectar and pollen, fish. other vertebrates, and blood) unparalleled among other living mammals. Their reproductive pattems range from seasonal monestry to polyestry, and mating systems inelude promiscuity, monogamy, and polygyny. The vast majority of what we know about the ecology of bats is derived from studies of only a few of the approximately 850 species, yet in the past two decades studies on bats have escalated to a level where many important empirical pattems and processes have been identified. This knowledge has strengthened our understanding of ecological relationships and encouraged hypothesis testing rather than perpetuated a catalog of miscellaneous observations.
