Book excerpt: Understanding the factors influencing the likelihood of persistence of real-world populations requires both an accurate understanding of the traits and behaviors of individuals within those populations (e.g., movement, habitat selection, survival, fecundity, dispersal) but also an understanding of how those traits and behaviors are influenced by landscape features. The federally threatened eastern indigo snake (EIS, Drymarchon couperi) has declined throughout its range primarily due to anthropogenically-induced habitat loss and fragmentation making spatially-explicit assessments of population viability and connectivity essential for understanding its current status and directing future conservation efforts. The primary goal of my dissertation was to understand how landscape features influence EIS population viability and connectivity in central peninsular Florida. I accomplished this through four components. First, I evaluated EIS movement patterns and space use including daily movement distance, home range size, within-individual home range overlap, and among-individual home range overlap and how these patterns varied by sex and season. Second, I conducted a multi-level, multi-scale habitat selection analysis to create spatially-explicit estimates of EIS habitat selection. Third, using the aforementioned data and previously published data, I developed an agent-based model for simulating EIS movement, survival, reproduction, and dispersal in central Florida. I used this model to determine how landscape features and conservation lands influence EIS occupancy across our study landscape. Finally, I used landscape genetics to determine how landscape features influenced genetic connectivity and to estimate resistance surfaces with which to model potential corridors. I found that male EIS maintain larger home ranges than females and move extensively during the breeding season in search of females. While seasonal home ranges within an individual strongly overlapped, individuals avoided home ranges of same-sex conspecifics. EIS selected home ranges and within-home range locations in areas of undeveloped upland habitat with high habitat heterogeneity and generally avoided urban. While EIS did not avoid roads, they rarely crossed primary and secondary roads. I used observed patterns of movement and habitat selection to calibrate my ABM. My ABM simulated larger male home ranges and smaller home ranges and lower survival in urbanized landscapes although simulated effect sizes were weaker than observed effect sizes. My model was unable to simulate observed patterns of within-individual home range overlap but accurately simulated survival in developed and undeveloped landscapes. EIS occupancy after a 15 year simulation was 56% and occupancy was most strongly affected, negatively, by urbanization. While the presence of conservation lands was not a strong driver of EIS occupancy, EIS occupancy was more consistently higher on conservation lands. EIS gene flow was most strongly associated with undeveloped uplands, urbanization, and habitat edge at the broadest scales we evaluated. Potential corridors were widespread in the southern half of our study area with substantial areas of potential habitat and corridor occurring outside of the existing conservation network. This work indicates that the LWR contains extensive areas capable of supporting EIS although increasing urbanization may have a negative impact on future persistence of EIS.

Book excerpt: Destruction of habitat due to urban sprawl, pollution, and deforestation has caused population declines or even extinction of many of the world's approximately 2,600 snake species. Furthermore, misconceptions about snakes have made them among the most persecuted of all animals, despite the fact that less than a quarter of all species are venomous and most species are beneficial because they control rodent pests. It has become increasingly urgent, therefore, to develop viable conservation strategies for snakes and to investigate their importance as monitors of ecosystem health and indicators of habitat sustainability. In the first book on snakes written with a focus on conservation, editors Stephen J. Mullin and Richard A. Seigel bring together leading herpetologists to review and synthesize the ecology, conservation, and management of snakes worldwide. These experts report on advances in current research and summarize the primary literature, presenting the most important concepts and techniques in snake ecology and conservation. The common thread of conservation unites the twelve chapters, each of which addresses a major subdiscipline within snake ecology. Applied topics such as methods and modeling and strategies such as captive rearing and translocation are also covered. Each chapter provides an essential framework and indicates specific directions for future research, making this a critical reference for anyone interested in vertebrate conservation generally or for anyone implementing conservation and management policies concerning snake populations.

Available in PDF, EPUB and Kindle. Book excerpt: LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS LANDSCAPE GENETICS: CONCEPTS, METHODS, APPLICATIONS Edited by Niko Balkenhol, Samuel A. Cushman, Andrew T. Storfer, Lisette P. Waits Landscape genetics is an exciting and rapidly growing field, melding methods and theory from landscape ecology and population genetics to address some of the most challenging and urgent ecological and evolutionary topics of our time. Landscape genetic approaches now enable researchers to study in detail how environmental complexity in space and time affect gene flow, genetic drift, and local adaptation. However, learning about the concepts and methods underlying the field remains challenging due to the highly interdisciplinary nature of the field, which relies on topics that have traditionally been treated separately in classes and textbooks. In this edited volume, some of the leading experts in landscape genetics provide the first comprehensive introduction to underlying concepts, commonly used methods, and current and future applications of landscape genetics. Consistent with the interdisciplinary nature of the field, the book includes textbook-like chapters that synthesize fundamental concepts and methods underlying landscape genetics (Part 1), chapters on advanced topics that deserve a more in-depth treatment (Part 2), and chapters illustrating the use of concepts and methods in empirical applications (Part 3). Aimed at beginning landscape geneticists and experienced researchers alike, this book will be helpful for all scientists and practitioners interested in learning, teaching, and applying landscape genetics.

This volume reviews our current understanding of avian population dynamics and explores ways in which population studies can contribute to effective conservation and management. Estimation of demographic parameters, the role of mathematical modelling, and the special problems of island populations and seabird populations are discussed. The emphasis throughout is on how bird populations are regulated under various constraints and conditions, including the impact of environmental changes.

Book excerpt: With gripping narrative power, The Condor's Shadow traces the ways in which human greed and ignorance have wreaked havoc on our ecological landscape. The heir apparent to Peter Matthiessen's 1959 classic Wildlife in America, The Condor's Shadow is a brilliant and compulsively readable study of the state of North American wildlife and what is being done to reverse the damage humans have caused. With equal respect for the smallest feather-mite and the fiercest grizzly, the frailest flower and the stateliest redwood, David S. Wilcove illustrates--in jargon-free, often witty prose--nature's delicate system of checks and balances, examining the factors that determine a species' vulnerability and the consequences of losing even the tiniest part of any ecosystem. An examination of both the heart-wrenching failures and stunning successes of our conservation efforts, The Condor's Shadow chronicles the destruction and resilience of our American wilderness and offers an insightful, eloquent overview that will appeal to avid conservationists and recreational nature-lovers alike.
