Book excerpt: Key features: Presents a contemporary snapshot of the mechanisms underlying the evolution and adaptation of behavior Explores how genetics, epigenetics, development, and environment shape behavior Discusses a broad range of behavioral repertoires and responses, including those related to thermoregulatory, foraging, predatory, displaying, social and escape strategies. Examines physiological and sensory mechanisms Covers the effects of various aspects of global change on behavior, with chapters that focus on the impacts of climate change on hydroregulatory behavior and behavioral responses to the effects of habitat alteration resulting from human-mediated change and colonization by invasive species. Lizards serve as focal organisms for many of biological questions related to evolution, ecology, physiology, and morphology. They are studied at multiple spatial and temporal scales, from the individual to the community level. This book, authored by expert contributors from around the world, explores behaviors underlying the evolution and adaptation of these organisms. It covers conceptual, empirical, and methodological approaches to the understanding of the role that natural and sexual selection play in molding the behavioral traits of lizards. This thorough, illustrated reference should stimulate discussion of the conceptual and methodological approaches for studying the behavioral traits of these fascinating and highly diverse vertebrates.

Available in PDF, EPUB and Kindle. Book excerpt: The diversity of animal signals has been widely documented, and the generality of animal signals also tantalizingly suggests that there are common mechanisms that have selected for their origin. However, while much progress has been made on some fronts, we still lack a general theory about why the diversity of signaling structures exist. Our compilation will directly address this gap by focusing on an exciting new arena of sexual selection, namely using functional approaches to understand signaling. This approach is rooted in the idea that many signals are designed to transmit important functional imformation that is both important for issues of male quality (and hence male competition), and female choice. The increasing use of technology in sexual selection studies has enabled researchers to test whether signaling is either constrained by, or accurately transmits information about functional capacities. Further, in animals that fight vigorously, functional capacities such as endurance or strength may make the difference between winning and losing. This volume brings together a diverse collection of researchers who are actively investigating how function and signaling are related. These researchers use both a variety of methods and taxa to study animal signaling, and we believe that this integrative view is important to open up fresh vistas for why animal signals have evolved.

Available in PDF, EPUB and Kindle. Book excerpt: "In a book both beautifully illustrated and deeply informative, Jonathan Losos, a leader in evolutionary ecology, celebrates and analyzes the diversity of the natural world that the fascinating anoline lizards epitomize. Readers who are drawn to nature by its beauty or its intellectual challenges—or both—will find his book rewarding."—Douglas J. Futuyma, State University of New York, Stony Brook "This book is destined to become a classic. It is scholarly, informative, stimulating, and highly readable, and will inspire a generation of students."—Peter R. Grant, author of How and Why Species Multiply: The Radiation of Darwin's Finches "Anoline lizards experienced a spectacular adaptive radiation in the dynamic landscape of the Caribbean islands. The radiation has extended over a long period of time and has featured separate radiations on the larger islands. Losos, the leading active student of these lizards, presents an integrated and synthetic overview, summarizing the enormous and multidimensional research literature. This engaging book makes a wonderful example of an adaptive radiation accessible to all, and the lavish illustrations, especially the photographs, make the anoles come alive in one's mind."—David Wake, University of California, Berkeley "This magnificent book is a celebration and synthesis of one of the most eventful adaptive radiations known. With disarming prose and personal narrative Jonathan Losos shows how an obsession, beginning at age ten, became a methodology and a research plan that, together with studies by colleagues and predecessors, culminated in many of the principles we now regard as true about the origins and maintenance of biodiversity. This work combines rigorous analysis and glorious natural history in a unique volume that stands with books by the Grants on Darwin's finches among the most informed and engaging accounts ever written on the evolution of a group of organisms in nature."—Dolph Schluter, author of The Ecology of Adaptive Radiation

Download or read book Eastern Collared Lizard (crotaphytus Collaris) Population Declines in Ozark Landscapes written by Casey Lee Brewster and published by . This book was released on 2019 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Eastern Collared Lizard (Crotaphytus collaris) has experienced extensive population declines over the past half century in the Ozark Mountains. Previous research suggests that glade habitat degradation through woody vegetation encroachment is an important factor resulting in population declines. In this dissertation I used information on time-energy budgets to investigate the link between habitat degradation and shifts in life history traits likely resulting in population declines of Eastern Collared Lizards (Crotaphytus collaris) in the Ozarks. In chapter one, I addressed the influence of dense woody vegetation encroachment on age-specific growth, body size, body condition and reproduction of C. collaris in northern Arkansas. Results from chapter one suggested that populations in encroached glades (defined by dense woody vegetation encroachment) experienced reduced body growth rates, delayed age of maturity, reduced clutch sizes and a nearly 50% decline in annual population fecundity rates. In chapter two, I investigated the role of behavior (postural adjustment) on the thermal ecology estimates of surface-active lizards using thermal data of C. collaris in one of my study populations. I used the data in chapter two to determine the most suitable methodologies to investigate the thermal ecology of C. collaris in northern Arkansas. In chapter three, I investigated the thermal sensitivity of digestion in C. collaris. Results in chapter three suggested that C. collaris digestion performance is affected by temperature, primarily through effects on passage times and voluntary feeding rates. In chapter four, I used results from the previous three chapters to erect several mechanistic hypotheses aimed at identifying the link between glade encroachment and reduced reproductive rates in C. collaris. Data in chapter four suggest C. collaris in encroached glades experience reduced environmental heat loads, shorter activity-times and less time-at-temperature suitable for digestive processing. The reduction in time-at-temperature for digestive processing resulted in lower energy available for growth and reproduction (4̃1%), which led to a near 50% decline in energy devoted to reproduction (# of eggs). Results from this dissertation provide a compelling explanation to the mechanisms causing a shift in life history traits that appear to play an important role in population declines of C. collaris in the Ozarks.

Book excerpt: Lizards utilise many different niches across a large variety of habitats. As a result of selective pressures exerted by the particular environments, many lizards in similar habitats have been shown to exhibit convergent morphologies. The performance of a lizard, or any organism for that matter, is a fundamental attribute employed in its survival, and therefore significantly impacts its fitness. The study of an organism's functional capacity is fairly new, with relatively few studies published. In studies of lizard functional capacity, performance is most often defined as the whole organism's ability to conduct an ecologically relevant task, and measures thereof have included sprint speed, bite force and locomotor endurance, amongst others. Primarily, the study of whole-organism performance includes those performance aspects related to dynamic animal movements, and not more passive' performance aspects (such as immune function levels or reproductive output) or those performance traits measured within an organism (such as enzyme reaction rate). This book focuses on the thermal ecology, genetic diversity and functional role lizards have in ecosystems. It discusses the influence of light on visual discrimination of sexually dichromatic dewlap colour in male and female brown anoles; the tolerance to thermal stress in lizard embryos; the leiolepis guttata; the impact on habitat modifications of thermoregulation in coastal sand dunes; the convergence in morphology in lizards; and sexual dimorphism and thermoregulatory behaviour in the long-tailed spiny lizard.

Available in PDF, EPUB and Kindle. Book excerpt: When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions – these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
