This book was released on 2021 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature is crucial to the optimal functioning of most physiological and behavioral processes in animals. For ectothermic crabs that inhabit shorelines, temperature fluctuations and anomalies pose a challenge for maintaining optimal body temperature. Here we examine the thermal ecology of two shore crabs, the ghost crab, Ocypode quadrata, and the striped shore crab, Pachygrapsus crassipes, using non-invasive infrared thermographic (IRT) technology. We tested the hypothesis that the exoskeleton helps buffer changes in environmental temperature by recording exoskeleton surface temperature in live and dead animals exposed to external heat sources. Crabs were first acclimated to room temperature in an experimental arena, then heat was sequentially added from a hot plate (conduction), IR emitter (radiation), and a heat lamp (radiation) until peak heat was reached, then all heat sources were sequentially removed. Exoskeleton surface temperature was recorded across multiple body locations (carapace, chelipeds and 5th pereopods) throughout increased and decreased heat exposure. For both species, dead crabs had significantly greater exoskeleton temperature flux than live crabs across all body locations, as well as the substrate. Thus, the exoskeleton itself does not appear to provide much thermal buffering, but the physiology and behavior of live crabs do. While O. quadrata spent most of the time sponging, P. crassipes actively avoided areas of high heat. This study demonstrates the responsiveness of the crab exoskeleton to environmental temperature changes and lays a foundation for exploring additional thermal adaptations of crabs on land using non-invasive IRT technology.
Download or read book Life Traces of the Georgia Coast written by Anthony J. Martin and published by Indiana University Press. This book was released on 2013-01-14 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.
Download or read book Principles of Animal Locomotion written by R. McNeill Alexander and published by Princeton University Press. This book was released on 2006-03-19 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can geckoes walk on the ceiling and basilisk lizards run over water? What are the aerodynamic effects that enable small insects to fly? What are the relative merits of squids' jet-propelled swimming and fishes' tail-powered swimming? Why do horses change gait as they increase speed? What determines our own vertical leap? Recent technical advances have greatly increased researchers' ability to answer these questions with certainty and in detail. This text provides an up-to-date overview of how animals run, walk, jump, crawl, swim, soar, hover, and fly. Excluding only the tiny creatures that use cilia, it covers all animals that power their movements with muscle--from roundworms to whales, clams to elephants, and gnats to albatrosses. The introduction sets out the general rules governing all modes of animal locomotion and considers the performance criteria--such as speed, endurance, and economy--that have shaped their selection. It introduces energetics and optimality as basic principles. The text then tackles each of the major modes by which animals move on land, in water, and through air. It explains the mechanisms involved and the physical and biological forces shaping those mechanisms, paying particular attention to energy costs. Focusing on general principles but extensively discussing a wide variety of individual cases, this is a superb synthesis of current knowledge about animal locomotion. It will be enormously useful to advanced undergraduates, graduate students, and a range of professional biologists, physicists, and engineers.
Download or read book Biology of the Land Crabs written by Warren W. Burggren and published by Cambridge University Press. This book was released on 1988-04-29 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in land crabs has burgeoned as biologists have increasingly focused on the evolution of terrestriality. Before the publication of this volume in 1988, there had been no single comprehensive source of information to serve biologists interested in the diverse aspects of terrestrial decapod crustacean. Biology of the Land Crabs was the first synthesis of recent and long-established findings on brachyuran and anomuran crustaceans that have evolved varying degrees of adaptation for life on land. Chapters by leading researchers take a coordinated evolutionary and comparative approach to systematics and evolution, ecology, behaviour, reproduction, growth and molting, ion and water balance, respiration and circulation, and energetics and locomotion. Each discusses how terrestrial species have become adapted from ancestral freshwater or marine forms. With its extensive bibliography and comprehensive index, including the natural history of nearly eighty species of brachyuran and anomuran crabs, Biology of the Land Crabs will continue to be an invaluable reference for researchers and advanced students.

Download or read book Brazilian Estuaries written by Paulo da Cunha Lana and published by Springer. This book was released on 2018-07-09 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.

Available in PDF, EPUB and Kindle. Book excerpt: "Bubbles over with the joy of scientific discovery as he shares his natural enthusiasm for the blend of sleuthing and imagination."—Publishers Weekly, starred review What if we woke up one morning all of the dinosaur bones in the world were gone? How would we know these iconic animals had a165-million year history on earth, and had adapted to all land-based environments from pole to pole? What clues would be left to discern not only their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, whether they lived underground, climbed trees, or went for a swim?Welcome to the world of ichnology, the study of traces and trace fossils – such as tracks, trails, burrows, nests, toothmarks, and other vestiges of behavior – and how through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the 21st century reader.
