Download or read book Behavioral Ecology of the Eastern Red backed Salamander written by Robert G. Jaeger and published by Oxford University Press. This book was released on 2016-08-04 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The small, terrestrial eastern red-backed salamander is abundant on many forest floors of northeastern North America. Dr. Robert Jaeger and many of his graduate students spent over 50 years studying this species in New York and Virginia, using ecological techniques in forests and behavioral experiments in laboratory chambers in an attempt to understand how this species interacts with other species in the forest and the components of its intra- and intersexual social behaviors. The competitive and social behaviors of this species are unusually complex for an amphibian. This species is highly aggressive towards other similar-size species where they cohabit in forests, often leading to very little geographic overlap between the species. The authors examine the fascinating behavioral traits of this species including social monogamy, mutual mate guarding, sexual coercion, inter-species communication, and conflict resolution.

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.
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.

Download or read book Genetic Structure Due to Variation in Breeding Time in a Salamander Population written by Scott A. Thomas and published by . This book was released on 2013 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fine-scale genetic structure of populations is traditionally thought to be shaped primarily by geographic barriers to reproduction among local populations. However, other mechanisms of isolation have been recognized, but little has been done to determine their relative roles in shaping genetic variation in natural populations. In this study, I test whether genetic structure within and among breeding ponds of spotted salamanders (Ambystoma maculatum) is influenced by within-pond variation in breeding time. I found significant genetic structure attributable to variation in breeding time within ponds. This temporal structure was not consistent across ponds, indicating it is a local and not a regional effect. However, this temporal structure did not fully resolve strong patterns of inbreeding within ponds, indicating that reproductive barriers operating with in ponds are more effective than either spatial or phenological ones. Together, these findings reveal complex relationships between genetic structure and variation in breeding phenology that would not be uncovered by spatial or temporal analyses alone.

Download or read book Amphibian Declines written by Michael Lannoo and published by Univ of California Press. This book was released on 2005-06-15 with total page 1117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.
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.

Download or read book Initial Juvenile Movement of Pond breeding Amphibians in Altered Forest Habitat written by Michael S. Osbourn and published by . 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 Size Structure and Intraguild Interactions Between Two Ambystoma Species written by Gwyneth Daunton and published by . This book was released on 2022 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraguild interactions affect population and community structure through a combination of competition and predation. Changes in size structure influence intraguild interactions by affecting the strength and direction of these species’ interactions. I tested for size-structured intraguild interactions in temporary pond ecosystems between marbled salamanders (Ambystoma opacum) and tiger salamanders (Ambystoma tigrinum) using an outdoor mesocosm experiment. I hypothesized that 1) A. opacum survivorship and growth would be negatively impacted when both species start at a similar size because tiger salamanders grow faster and are more aggressive 2) A. tigrinum will grow slower and have lower survivorship when they occur with large A. opacum because A. opacum will outcompete A. tigrinum and prey upon them. There was no support for the second hypothesis, A. tigrinum grew and survived the same regardless of A. opacum size. However, I found support for the first hypothesis. Small A. opacum mortality was greatest when they occurred with small A. tigrinum suggesting changes in size structure resulting in these two species occurring together at similar sizes will negatively impact A. opacum populations through intraguild predation. Climate change will likely affect the distribution and abundance of species in temporary pond ecosystems and influence size-structured interactions that impact population and community structure.
