Download or read book The Spatial Ecology of Predator-Prey Interactions: A Case Study of Yellowstone Elk, Wolves, and Cougars written by Michel T. Kohl and published by . This book was released on 2019 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predators can serve as an important top-down driver of ecosystems via their influence on prey behavior. Although predator effects on prey behavior (or traits) may be as strong as or stronger than predator effects on prey abundance in small-scale, experimental systems, it is unclear whether behavioral effects are as dominant in large-scale, free-living systems. The objective of this project was to improve our ecological understanding of the spatio-temporal interactions between large predators and their primary prey source in a free-living system. Specifically, I used data from northern Yellowstone to evaluate 1) the role of predator diel activity on prey habitat selection of risky places, 2) how prey operate in a landscape composed of multiple predators that occupy different spatial and temporal niches, and 3) how the density - and behaviorally-meditated effects of large predators influence the large-scale spatial distribution of a prey population. In Chapter 2, I show that the predictability of daily wolf (Canis lupus) hunting activity provided an opportunity for elk (Cervus elaphus) to use risky places during safe times, which in essence, flattened (i.e., minimized) the landscape of fear in Yellowstone. In Chapter 3, I show that wolves and cougars (Puma concolor) hunt in different places, and at different times, which provided a refugia from these predators in time and space that likely minimized overall predation risk in an environment that was spatially saturated with wolves and cougars. In Chapter 4, I show that the current spatial distribution of elk across the northern range of Yellowstone is driven primarily by demographic rather than behavioral mechanisms. Overall, the results from chapters 2-4 suggest that any trophic cascade from predators, to prey, to deciduous woody plants in Yellowstone National Park is likely due to demographic mechanisms rather than a landscape of fear. More broadly, this research identifies a previously overlooked behavioral trait of predators, diel activity, which prey can use to minimize the effect of predators on sophisticated prey. Together, this study advances the field of ecology by quantifying the ecological importance of fear in a large-scale, free-living system.

Download or read book The Ecology of Predation at the Microscale written by Edouard Jurkevitch and published by Springer Nature. This book was released on 2020-06-29 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book will provide an update on our understanding of predator-prey through the prism of ecology, physiology, molecular biology, and mathematical modelling. The integration of these different perspectives while focusing on the microbial realm will highlight the importance of scale in ecological interactions, and their importance in applications. This book should thereby contribute to theoretical as well as to applied ecologists and microbiologists. Furthermore, the detailed but amenable chapters could serve as the basis of teaching advanced courses in (microbial) ecology and environmental microbiology.This work is a collection of articles that discuss microbial predation from a variety of perspectives. It provides the readers a concise resource describing factors that are critical for several different predatory microbes, including Myxobacterium spp. and Bdellovibrio-and-like organisms (BALOs), including the mechanisms involved, ecological conditions that adversely impact it and potential applications in aquaculture and bioproduction. The first half of this collection focuses more on ecological aspects of predation, with in-depth discussions on “wolf pack” predators, the presence and activities of predators in waste-water treatment plants and the role of intraguild predatory relationships, i.e., when two different predators are competing for a single prey but also interact with one another. The reader will gain a deeper understanding of the predatory mechanisms involved and their ecological roles. In the latter half, emphasis is given more to the application and limitations of predators. In addition to discussing secondary metabolite production within different microbial predators, the readers will also learn how predators are being used to purify secondary metabolites from prey. This section also discusses the expanding and promising role of predation in aquaculture, focusing on the application of predators to reduce pathogenic populations, but includes some important caveats for young researchers to consider and follow when working with Bdellovibrio. This work is written for both experienced researchers already in the field and for young scientists who are captivated by the thought of predation at the microscale and its growing importance within a wide-array of fields.

Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with paleolimnological studies, simulation modeling, and small-scale enclosure experiments. Contributors describe consequences of predator-prey interactions, behavioral responses of fishes, diel vertical migration of zooplankton, plankton community change, primary production, nutrient cycling and microbial processes. Paleolimnological techniques enable the reconstruction of trophic interactions from past decades. Prospects for analyzing the interaction of food web structure and nutrient input in lakes are explored.

This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.

Book excerpt: Cave organisms are the ‘monsters’ of the underground world and studying them invariably raises interesting questions about the ways evolution has equipped them to survive in permanent darkness and low-energy environments. Undertaking ecological studies in caves and other subterranean habitats is not only challenging because they are difficult to access, but also because the domain is so different from what we know from the surface, with no plants at the base of food chains and with a nearly constant microclimate year-round. The research presented here answers key questions such as how a constant environment can produce the enormous biodiversity seen below ground, what adaptations and peculiarities allow subterranean organisms to thrive, and how they are affected by the constraints of their environment. This book is divided into six main parts, which address: the habitats of cave animals; their complex diversity; the environmental factors that support that diversity; individual case studies of cave ecosystems; and of the conservation challenges they face; all of which culminate in proposals for future research directions. Given its breadth of coverage, it offers an essential reference guide for graduate students and established researchers alike.

Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Download or read book The Lake Charr Salvelinus namaycush: Biology, Ecology, Distribution, and Management written by Andrew M. Muir and published by Springer Nature. This book was released on 2021-03-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.

Available in PDF, EPUB and Kindle. Book excerpt: We conceived the idea for this book after teaching a graduate seminar on 'Habitat Complexity' at The University of South Florida. Discussions during the seminar led us to conclude that similar goals were to be found in studies of the topic that spanned the breadth of ecological research. Yet, the exact meaning of 'habitat structure', and the way in which it was measured, seemed to differ widely among subdisciplines. Our own research, which involves several sorts of ecology, convinced us that the differences among subdisciplines were indeed real ones, and that they did inhibit communica tion. We decided that interchange of ideas among researchers working in marine ecology, plant-animal interactions, physiological ecology, and other more-or-less independent fields would be worthwhile, in that it might lead to useful generalizations about 'habitat structure'. To foster this interchange of ideas. we organized a symposium to attract researchers working with a wide variety of organisms living in many habitats, but united in their interest in the topic of 'habitat structure'. The symposium was held at The University of South Florida's Chinsegut Hill Conference Center, in May. 1988. We asked participants to think about 'habitat structure' in new ways; to synthesize important, but fragmented, information; and. perhaps. to consider ways of translating ideas across systems. The chapters contained in this book reflect the participants' attempts to do so. The book is divided into four parts, by major themes that we have found useful categorizations.
