Book Description
Changes in the ocean including acidification, increasing temperatures, loss of habitat, and increased hypoxic events has the potential to change predator-prey relationships. These changes in single interactions can then have effects on population sizes, community structures, and changes in trophic cascades. Understanding how changing abiotic factors impact predator-prey relationships will be crucial for understanding what populations and communities will look like under future ocean conditions. In this review, the goals are to (1) summarize the current knowledge on how changing ocean conditions affect predator-prey relationships; (2) describe an example predator-based approach to examine how changing these changing factors impact predator-prey relationships; and (3) test the effectiveness of this method on a simple predator-prey relationship between the marine mesopredator fish lane snapper (Lutjanus synagris) and ghost shrimp prey (Palaemonetes paludosus). The results of this study summarize over 60 studies relating to factors affecting predator-prey relationships and outlines a methodology appropriate for studying predator-prey interactions. The results of the predation trials revealed that predation efficiency of the lane snapper was significantly impacted by temperature, while habitat complexity was found not to be statistically significant.

Biomechanics in Animal Behaviour
Author: R.W. BlakePublisher: Garland Science
ISBN: 1000443299
Category : Science
Languages : en
Pages : 360
Book Description
Biomechanics in Animal Behaviour offers a unique approach by integrating fully the fields of animal behaviour and biomechanics. It demonstrates how an understanding of biomechanical issues is an important part of evaluating and predicting animal behaviour. The book examines how behaviour is determined and/or constrained by biomechanical variables such as hydrodynamics, aerodynamics, kinematics, and the mechanical properties of biomaterials.
Foraging

Category : Science
Languages : en
Pages : 626
Book Description
Foraging is fundamental to animal survival and reproduction, yet it is much more than a simple matter of finding food; it is a biological imperative. Animals must find and consume resources to succeed, and they make extraordinary efforts to do so. For instance, pythons rarely eat, but when they do, their meals are large—as much as 60 percent larger than their own bodies. The snake’s digestive system is normally dormant, but during digestion metabolic rates can increase fortyfold. A python digesting quietly on the forest floor has the metabolic rate of thoroughbred in a dead heat. This and related foraging processes have broad applications in ecology, cognitive science, anthropology, and conservation biology—and they can be further extrapolated in economics, neurobiology, and computer science. Foraging is the first comprehensive review of the topic in more than twenty years. A monumental undertaking, this volume brings together twenty-two experts from throughout the field to offer the latest on the mechanics of foraging, modern foraging theory, and foraging ecology. The fourteen essays cover all the relevant issues, including cognition, individual behavior, caching behavior, parental behavior, antipredator behavior, social behavior, population and community ecology, herbivory, and conservation. Considering a wide range of taxa, from birds to mammals to amphibians, Foraging will be the definitive guide to the field.
Biological Invasions in Marine Ecosystems
Author: Gil RilovPublisher: Springer Science & Business Media
ISBN: 354079235X
Category : Science
Languages : en
Pages : 642
Book Description
Biological invasions are considered to be one of the greatest threats to the integrity of most ecosystems on earth. This volume explores the current state of marine bioinvasions, which have been growing at an exponential rate over recent decades. Focusing on the ecological aspects of biological invasions, it elucidates the different stages of an invasion process, starting with uptake and transport, through inoculation, establishment and finally integration into new ecosystems. Basic ecological concepts - all in the context of bioinvasions - are covered, such as propagule pressure, species interactions, phenotypic plasticity, and the importance of biodiversity. The authors approach bioinvasions as hazards to the integrity of natural communities, but also as a tool for better understanding fundamental ecological processes. Important aspects of managing marine bioinvasions are also discussed, as are many informative case studies from around the world.
