Book Description
White-Nose Syndrome (WNS) is an epizootic disease in hibernating bats caused by the fungus Pseudogymnoascus destructans. Surveillance for P. destructans at bat hibernacula consists primarily of visual surveys of bats, collection of potentially infected bats, and submission of these bats for laboratory testing. Cryptic infections (bats that are infected but display no visual signs of fungus) could lead to the mischaracterization of the infection status of a site and the inadvertent spread of P. destructans. We determined the efficacy of visual detection of P. destructans by examining visual signs and molecular detection of P. destructans on 928 bats of six species at 27 sites during surveys conducted from January through March in 2012–2014 in the southeastern USA on the leading edge of the disease invasion. Cryptic infections were widespread with 77% of bats that tested positive by qPCR showing no visible signs of infection. The probability of exhibiting visual signs of infection increased with sampling date and pathogen load, the latter of which was substantially higher in three species (Myotis lucifugus, M. septentrionalis, and Perimyotis subflavus). In addition, M. lucifugus was more likely to show visual signs of infection than other species given the same pathogen load. Nearly all infections were cryptic in three species (Eptesicus fuscus, M. grisescens, and M. sodalis), which had much lower fungal loads. The presence of M. lucifugus or M. septentrionalis at a site increased the probability that P. destructans was visually detected on bats. Our results suggest that cryptic infections of P. destructans are common in all bat species, and visible infections rarely occur in some species. However, due to very high infection prevalence and loads in some species, we estimate that visual surveys examining at least 17 individuals of M. lucifugus and M. septentrionalis, or 29 individuals of P. subflavus are still effective to determine whether a site has bats infected with P. destructans. In addition, because the probability of visually detecting the fungus was higher later in winter, surveys should be done as close to the end of the hibernation period as possible.

Book Description
"...a number of chapters provide excellent summaries of the modern methods available for studying fungal ecology, along with those more traditional methods that are still extremely valuable...overall it is a hugely valuable compendium of fungal ecology research. It is a must for the library shelf." -Lynne Boddy, Cardiff University, UK, Mycological Research, 2006 "These 44 chapters are an excellent starting point for anyone interested in fungal communities, in the broadest sense of the term. It is a book for dipping into...may be the last comprehensive treatment of fungal communities before the molecular revolution." -Meriel Jones, University of Liverpool, UK, Microbiology Today "... the scope of the work is tremendous. ... Excellent chapters providing overviews of methods ... provide a snap shot of the current approaches used to understand fungal communities at several levels of organization. This book should probably be on the shelf of every student of mycology, and many ecologists too. For all students, this book should be a valuable resource and source of inspiration." -Daniel Henk, Imperial College Faculty of Medicine, London, in Inoculum, Vol. 59, No. 3, May 2008 "Thorough taxonomic and subject indices further aid the reader in navigating through multiple authors’ treatments of subjects of interest." - Anthony Amend, Department of Botany, University of Hawaii at Manoa in Economic Botany, V. 61 ? In all subjects in science, new findings and the use of new technologies allow us to develop an ever-greater understanding of our world. Expanded and updated coverage in the fourth edition includes: Adds new sections on Integrating Genomics and Metagenomics into Community Analysis, Recent Advances in Fungal Endophyte Research, Fungi in the Built Environment, and Fungal Signaling and Communication Includes a broader treatment of fungal communities in natural ecosystems with in-depth coverage of fungal adaptations to stress and conservation Expands coverage of the influence of climate change on fungi and the role of fungi in organically polluted ecosystems Includes contributions from scientists from 20 nations to illustrate a true global approach for bridging gaps between ecological concepts and mycology

Book Description
This book provides in-depth insights into epidemic and emerging mycoses in various animal groups. The different categories of pathogens and outbreak fungi are discussed. In an introductory chapter, the reader will be provided basic information on fungal infections that are non-transmissible, infections from a common environmental source known as sapronoses, and zoophilic fungal pathogens in various animal species and populations, worldwide Chapter 2 details the vocabulary and terminology that is required in the scientific literature in order to maintain clarity of expression to the field of Mycology. Chapters 3 to 9 discuss epidemic mycoses with a reservoir in animals and occasional outbreaks, including dermatophytoses, coccidioidomycosis, histoplasmosis, paracoccidioidomycosis, adiaspiromycosis and similar diseases, blastomycosis, and paracoccidioidomycosis ceti (lacaziosis/lobomycosis). Chapters 10 to 15 comprise emerging mycoses in animals that include feline sporotrichosis, lethargic crab disease, emergence of C. gattii in animals and zoonotic potential, white-nose syndrome in hibernating bats, chytridiomycosis in frogs and salamanders and aspergillosis in cats. The last chapter is about treatment possibilities, antifungal use in veterinary practice, and emergence of resistance. The book will address medical and veterinary mycologists, microbiologists, veterinarians, infectious disease specialists, epidemiologists, ecologists, public health scientists from academia and industry as well as graduate students, PhD students and postdocs in the field.

Book Description
Conservation physiology is a rapidly expanding, multidisciplinary field that utilizes physiological knowledge and tools to understand and solve conservation challenges. This novel text provides the first consolidated overview of its scope, purpose, and applications, with a focus on wildlife. It outlines the major avenues and advances by which conservation physiology is contributing to the monitoring, management, and restoration of wild animal populations. This book also defines opportunities for further growth in the field and identifies critical areas for future investigation. By using a series of global case studies, contributors illustrate how approaches from the conservation physiology toolbox can tackle a diverse range of conservation issues including the monitoring of environmental stress, predicting the impact of climate change, understanding disease dynamics, improving captive breeding, and reducing human-wildlife conflict. Moreover, by acting as practical road maps across a diversity of sub-disciplines, these case studies serve to increase the accessibility of this discipline to new researchers. The diversity of taxa, biological scales, and ecosystems highlighted illustrate the far-reaching nature of the discipline and allow readers to gain an appreciation for the purpose, value, applicability, and status of the field of conservation physiology. Conservation Physiology is an accessible supplementary textbook suitable for graduate students, researchers, and practitioners in the fields of conservation science, eco-physiology, evolutionary and comparative physiology, natural resources management, ecosystem health, veterinary medicine, animal physiology, and ecology.

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.
