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.

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 Reproductive and Spatial Ecology of a Pond breeding Amphibian Community written by Michelle Lynn Guidugli and published by . This book was released on 2009 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many amphibian species the temporal and spatial patterns of migration are poorly understood. To better understand these processes, an ephemeral pond-breeding amphibian community was studied at Central Kentucky Wildlife Management Area, Madison County, Kentucky. The study pond was completely encircled using a drift fence-pitfall trap array and checked continually from January to October 2009. Meteorological variables including rainfall and air temperature and the habitat variable distance to forest edge were measured to determine their influence on amphibian migrations. Several amphibians including Rana catesbeiana (American Bullfrog), Ambystoma jeffersonianum (Jefferson's salamander), and A. maculatum (Spotted Salamander) inhabited this pond; however, A. jeffersonianum and A.maculatum were dominant in their abundance and length of time they occupied the pond for breeding. Breeding migrations for A.maculatum and A. jeffersonianum were correlated with variables such as daily cumulative precipitation and mean air temperature; however cumulative precipitation was not correlated with existing migrations for these species. Movements to the pond were non-randomly oriented for A. jeffersonianum and A.maculatum and non-randomly oriented away from the pond for A.maculatum. Both migrations were positively correlated with distance to forest edge for A.maculatum and A. jeffersonianum; however, the strongest association was found for A.maculatum exiting migrations. These results exemplify how closely movements of amphibian species are linked to their environment. Amphibian populations are declining due to habitat destruction and fragmentation; therefore, this understanding of when and where different aspects of their habitat are used will aid in future conservation and land management.

Available in PDF, EPUB and Kindle. Book excerpt: Roads may threaten the persistence of wildlife populations by acting as barriers to movement and/or sources of increased mortality across the landscape. Amphibians and reptiles have been identified as being particularly susceptible to negative road impacts. Many species migrate annually among habitats to support basic life history requirements such as breeding, development, foraging, and overwintering. For these species, individuals may need to successfully cross roads multiple times each year for the population to persist. Many are slow-moving and freeze in the presence of danger, making it almost impossible for them to avoid oncoming vehicles. Although there are a plethora of road mortality location and count data, the effects of road mortality on the long-term viability of amphibian and reptile populations and metapopulations are mostly unknown due to a lack of information on their abundance, vital rates, behavior, and spatial and temporal dynamics.
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.
