Available in PDF, EPUB and Kindle. Book excerpt: Human-induced habitat change is widely regarded as a primary factor threatening the persistence of species. One major consequence of habitat alteration is its effect on the movement behavior of individuals. Spotted salamanders (Ambystoma maculatum) are forest-dependent, pond-breeding amphibians. I used a combination of empirical studies of juvenile spotted salamander movement and individual-based modeling to investigate the influence of habitat amount and arrangement on juvenile salamander survival. Salamanders moved straighter and with fewer turns through field habitat compared to both forest and early successional habitat. Movement in forest was well approximated by a correlated random walk. Salamanders oriented movement toward forest when released at most 10 m from the forest edge. Different movement strategies were optimal under different habitat modification scenarios. The strength of movement bias toward habitat had a significant effect on the probability of individuals locating habitat. The degree to which movement bias affected the probability of locating habitat differed based on assumptions of habitat clumping and density-dependent mortality. My results indicated that the amount and configuration of habitat surrounding wetlands affect optimal movement behavior, and habitat managers should consider the configuration of habitat surrounding wetlands when designing conservation measures.

This book was released on 2012 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial juvenile movement phase represents the first stage of the multi-phase process of natal dispersal. My objective was to investigate how alterations in forest habitat quality impact initial juvenile movement success and behavior. I conducted a mark-recapture study of juvenile Spotted Salamanders (Ambystoma maculatum) and Green Frogs (Lithobates clamitans) within experimental forest arrays. Spotted Salamander movement success was significantly greater in partial-cut treatments than the control or clearcut treatments. Green Frog movement success was greatest in the control forest. A greater proportion of both Spotted Salamander and Green Frog juveniles, initially moving through open-canopy habitats, redirected their movements toward forests. I next sought to identify how fine-scale habitat quality affects juveniles' decisions to cease moving away from their natal pond and settle. By using experimental enclosures, I attempted to isolate the effects of forest canopy and microhabitat manipulations on salamander settling decisions relative to unmanipulated forest controls. For Spotted Salamanders and Ringed Salamanders (A. annulatum) settling probability decreased with forest canopy removal and compacted soils. Spotted salamander settling probability increased with higher refuge densities.

Download or read book The Ecology and Behavior of Amphibians written by Kentwood D. Wells and published by University of Chicago Press. This book was released on 2010-02-15 with total page 1162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems. Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation. An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.

Available in PDF, EPUB and Kindle. Book excerpt: A practical guide that explains how we can design roads that are compatible with populations of small wildlife. Few of us think twice about driving on roads. Yet the very presence of roads and the act of driving on them can impact the ecological infrastructure that supports an animal's daily life. What chance does a turtle have of successfully laying its eggs when it needs to traverse a busy highway? Is it realistic to expect small mammals to breed when an interstate thoroughfare subdivides their population? These are the sorts of challenges faced by small, often slow-moving, animals, challenges that road engineers and ecologists are trying to address. For countless small species, vehicles traveling at high speeds are nothing less than missiles shooting across migration pathways. For too many animals, the danger can lead to the loss of populations, in part because they simply are not programmed to react to traffic. Salamanders faced with a two-lane road between the forest and their aquatic breeding site, for example, will typically cross that road regardless of the congestion. The result can be hundreds of flattened animals in a single night. Roads and Ecological Infrastructure is the first book to focus on reducing conflict between roads and small animals. Highlighting habitat connections and the challenges and solutions from both transportation and ecological perspectives, the volume covers various themes, including animal behavior related to roads and design approaches to mitigate the negative effects of roads on wildlife. The chapter authors—from transportation experts to university researchers—each promote a goal of realistic problem solving. Conceptual and practical, this book will influence the next decade or more of road design in ecologically sensitive areas and should prevent countless unnecessary wildlife fatalities.

Download or read book Community Ecology and Salamander Guilds written by Nelson G. Hairston and published by Cambridge University Press. This book was released on 1987-11-27 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: This informative book, first published in 1987, presents the theories of community ecology within the context of a natural example. The text describes and examines issues in community ecology and shows how research on salamanders has helped to solve some of the problems surrounding the theories. Salamanders exist in stable populations of the kind assumed in community theory and are more appropriate than most other animals for research on the applications of that theory. The interesting and meaningful results, collected from observation on these excellent subjects posed challenges to beliefs within community ecology. Life histories of salamanders, fieldwork in distinctly differing habitats, competition, predation and evolution are discussed in an easily readable text. Professional ecologists and students of community ecology and herpetology will be interedted in the information synthesised in this book.

This book was released on 2002-08 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapidly increasing global population has dramatically increased the demands for natural resources and has caused significant changes in quantity and quality of natural resources. To achieve sustainable resource management, it is essential to obtain insightful guidance from emerging disciplines such as landscape ecology. This text addresses the links between landscape ecology and natural resource management. These links are discussed in the context of various landscape types, a diverse set of resources and a wide range of management issues. A large number of landscape ecology concepts, principles and methods are introduced. Critical reviews of past management practices and a number of case studies are presented. This text provides many guidelines for managing natural resources from a landscape perspective and offers useful suggestions for landscape ecologists to carry out research relevant to natural resource management. In addition, it will be an ideal supplemental text for graduate and advanced undergraduate ecology courses.

This book was released on 2012-04-14 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for ecologists interested in capturing their understandings of how natural systems work in software – to help inform their work and communicate the consequences of proposed management plans. Historically, ecologists had to rely on the skills of trained computer programmers to modeling natural systems, but now a new generation of software is allowing ecologists to directly capture their understandings of systems in software. This book is a compilation of spatially explicit simulation models developed by ecologists and planners without any formal computer programming skills. Readers will be inspired to believe that they too can create similar models of the systems with which they are familiar.
