Predation by R. J. Taylor Pdf

When assuming the task of preparing a book such as this, one inevitably wonders why anyone would want to read it. I have always sympathized with Charles Elton's trenchant observation in his 1927 book that 'we have to face the fact that while ecological work is fascinating to do, it is unbearably dull to read about . . . ' And yet several good reasons do exist for producing a small volume on predation. The subject is interesting in its own right; no ecologist can deny that predation is one of the basic processes in the natural world. And the logical roots for much currently published reasoning about predation are remarkably well hidden; if one must do research on the subject, it helps not to be forced to start from first principles. A student facing predator-prey interactions for the first time is confronted with an amazingly diverse and sometimes inaccessible literature, with a ratio of wheat to chaff not exceeding 1: 5. A guide to the perplexed in this field does not exist at present, and I hope the book will serve that function. But apart from these more-or-Iess academic reasons for writing the book, I am forced to it by my conviction that predators are important in the ecological scheme. They playa critical role in the biological control of insects and other pests and are therefore of immediate economic concern.

Social Predation by Guy Beauchamp Pdf

The classic literature on predation dealt almost exclusively with solitary predators and their prey. Going back to Lotka-Volterra and optimal foraging theory, the theory about predation, including predator-prey population dynamics, was developed for solitary species. Various consequences of sociality for predators have been considered only recently. Similarly, while it was long recognized that prey species can benefit from living in groups, research on the adaptive value of sociality for prey species mostly emerged in the 1970s. The main theme of this book is the various ways that predators and prey may benefit from living in groups. The first part focusses on predators and explores how group membership influences predation success rate, from searching to subduing prey. The second part focusses on how prey in groups can detect and escape predators. The final section explores group size and composition and how individuals respond over evolutionary times to the challenges posed by chasing or being chased by animals in groups. This book will help the reader understand current issues in social predation theory and provide a synthesis of the literature across a broad range of animal taxa. Includes the whole taxonomical range rather than limiting it to a select few Features in-depth analysis that allows a better understanding of many subtleties surrounding the issues related to social predation Presents both models and empirical results while covering the extensive predator and prey literature Contains extensive illustrations and separate boxes that cover more technical features, i.e., to present models and review results

People and Predators by Defenders of Wildlife Pdf

Carnivores provide innumerable ecological benefits and play a unique role in preserving and maintaining ecosystem services and function, but at the same time they can create serious problems for human populations. A key question for conservation biologists and wildlife managers is how to manage the world's carnivore populations to conserve this important natural resource while mitigating harmful impacts on humans. In People and Predators, leading scientists and researchers offer case studies of human-carnivore conflicts in a variety of landscapes, including rural, urban, and political. The book covers a diverse range of taxa, geographic regions, and conflict scenarios, with each chapter dealing with a specific facet of human-carnivore interactions and offering practical, concrete approaches to resolving the conflict under consideration. Chapters provide background on particular problems and describe how challenges have been met or what research or tools are still needed to resolve the conflicts. People and Predators will helps readers to better understand issues of carnivore conservation in the 21st century, and provides practical tools for resolving many of the problems that stand between us and a future in which carnivores fulfill their historic ecological roles.

The Predator by RuNyx Pdf

What happens when an unstoppable force meets an immovable object in the field of death? In the dark underbelly of the mob, Tristan Caine has been an anomaly. As the only non-blooded member in the high circle of the Tenebrae Outfit, he is an enigma to all - his skills unparalleled, his morality questionable, and his motives unknown. He is lethal and he knows it. As does Morana Vitalio, the genius extraordinaire daughter of the rival family. What Caine does with weapons, Morana does with computers. When a twenty-year old mystery resurfaces, Morana infiltrates Caine's house, intent on killing him, unaware of a tie that binds them together. Hate, heat, and history clash together with unexpected sparks. But something bigger, something worse is happening in their world. And despite their animosity, only they can fight it down. The Predator is an enemies-to-lovers, dark, contemporary romance set in a fictional universe with mafia, passion and incredible storytelling.

Competition versus Predation in Aviation Markets by Peter Forsyth,David W. Gillen,Otto G. Mayer,Hans-Martin Niemeier Pdf

Prior to liberalization, there was little scope for predatory behaviour in the aviation market. However, following deregulation, new entrants sought to compete with entrenched incumbents. Low-cost carriers (LCCs) gained significant market share, which in turn provoked many different kinds of defensive response. Having put pressure on established carriers, low-cost airlines are themselves feeling the pressure of competition from new operators. While it is normal and natural for airlines to react to competition - modifying their services, the ways in which they offer them and their prices - when does aggressive commercial behaviour go too far and become predation? This book considers what exactly is meant by 'predation' in the aviation environment, and explores the strategies LCCs adopt in order to gain market share, as well as the strategies of the established airlines in response to competition from new entrants to the market. It also addresses the key question of what competition policy should do to ensure intensive competition. Competition versus Predation in Aviation Markets brings together contributions from around the world, from airlines, government agencies, leading academics and consultants, providing a wealth of perspectives on a business practice crucial to airline survival.

The Ethology of Predation by E. Curio Pdf

Predation is an ecological factor of almost universal importance for the biol ogist who aims at an understanding of the habits and structures of animals. Despite its pervasive nature opinions differ as to what predation really is. So far it has been defined only in negative terms; it is thought not to be par asitism, the other great process by which one organism harms another, nor filter-feeding, carrion-eating, or browsing. Accordingly, one could define predation as a process by which an animal spends some effort to locate a live prey and, in addition, spends another effort to mutilate or kill it. Ac cording to this usage of the word a nudibranch, for example, that feeds on hydroids would be a predator inasmuch as it needs some time to locate col onies of its prey which, after being located, scarcely demand more than eating, which differs little from browsing. From the definition just proposed consumption of the prey following its capture has been intentionally omit ted. Indeed, an animal may be disposed of without being eaten. Hence the biological significance of predation may be more than to maintain nutrition al homeostasis. In fact, predation may have something in common with the more direct forms of competition, a facet that will be only cursorily touched upon in this book.

The Neuroethology of Predation and Escape by Keith T. Sillar,Laurence D. Picton,William J. Heitler Pdf

The forces of natural selection have been a primary driver in the evolution of adaptive animal behaviours. On the one hand animals must evade predation in order to survive and pass on their genes; on other hand, and for the same underlying reasons, animals must also be capable of successfully capturing prey. This situation has led to an evolutionary arms race in which predator and prey are locked in the battle to survive. A common strategy in each situation is to enhance the speed of response, resulting in the evolution of neural, muscular and biomechanical designs that produce supremely fast and eye-catching behavioral responses. The aim of this book is to illuminate the design principles of escape and predatory behaviours using a series of case histories from different animal groups and to emphasize the convergent evolution of neural circuitry that optimizes the chances of survival. Using these case histories the authors describe sensory mechanisms that aid prey and predator detection, central neural circuit designs that increase speed of response and neuromuscular and biomechanical properties that aid the performance of escape and predatory movements.

Predation in Vertebrate Communities by Bogumila Jedrzejewska,Wlodzimierz Jedrzejewski Pdf

Predation, one of the most dramatic interactions in animals' lives, has long fascinated ecologists. This volume presents carnivores, raptors and their prey in the complicated net of interrelationships, and shows them against the background of their biotic and abiotic settings. It is based on long-term research conducted in the best preserved woodland of Europe's temperate zone. The role of predation, whether limiting or regulating prey (ungulate, rodent, shrew, bird, and amphibian) populations, is quantified and compared to parts played by other factors: climate, food resources for prey, and availability of other potential resources for predators.

How to High Tea with a Hyena (and Not Get Eaten) by Rachel Poliquin Pdf

The second book in a hilarious illustrated non-fiction chapter book series starring a savvy and stylish cockroach who guides the reader through an encounter with a charming -- and dangerous -- predator. Is this hyena drooling for tea and crumpets . . . or for you?! Celeste is a cockroach, and everyone knows that cockroaches are survivors, so who better to give advice on surviving an encounter with a polite predator? High teas are dainty meals with pretty teacups: you nibble tiny cakes, sip milky tea and chit-chat about not-so-important things like why doughnuts have holes and if fish have eyebrows. But Ruby the hyena is loud, ferocious and tends to slober. High-speed gobbling makes good sense in the wild, but it is a definite no-no in the tearoom! And Ruby just happens to be Queen of a very large clan of hungry hyenas. Will high tea be ruined by uninvited guests? Is Ruby peckish for something other than Celeste's famous cream buns? Using her vast knowledge of hyenas, Celeste comes up with lots of strategies to get through high tea in one piece. Many of her suggestions are dangerous, most are absurd, but all are based on true hyena biology and hunting behavior.

Small Predators by Jennifer Black Pdf

In this vibrant debut, Jennifer Ilse Black combines prose, lists, and structural experimentation. Small Predators follows a collective of student activists as they cope with the aftermath of a violent political demonstration carried out against their university by a member of their collective, Mink. The story's narrator, Fox, recounts Mink's addiction to a form of physical self-harm, both a violence motivated by guilt of privilege and a method of coping with political vulnerability. As Fox navigates her anger with Mink, debating whether or not she should confront or forgive her, we discover that each member of the collective is performing their own acts of self-violence. As Canadian millennials, Fox and her friends were born into the era of climate anxiety--told again and again that more must be done to save humanity's future at the same time that pipelines were expanded, rainforests were cleared, and chemical waste was dumped into the ocean. Struggling to imagine a resistance that isn't futile, the young activists turn violently on themselves and each other, creating sites of political action and care within their physical bodies.

From an Antagonistic to a Synergistic Predator Prey Perspective by Tore Johannessen Pdf

From an Antagonistic to a Synergistic Predator Prey Perspective: Bifurcations in Marine Ecosystems is a groundbreaking reference that challenges the widespread perception that predators generally have a negative impact on the abundance of their prey, and it proposes a novel paradigm — Predator-prey Synergism — in which both predator and prey enhance abundance by their co-existence. Using this model, the text explains a number of issues that appear paradoxical in the case of a negative predator-prey relationship, including observed ecosystem bifurcations (regime shifts), ecosystem resilience, red tides in apparently nutrient depleted water, and the dominance of grazed phytoplankton over non-grazed species under high grazing pressure. This novel paradigm can also be used to predict the potential impact of global warming on marine ecosystems, identify how marine ecosystem may respond to gradual environmental changes, and develop possible measures to mitigate the negative impact of increasing temperature in marine ecosystems. This book approaches the long-standing question of what generates recruitment variability in marine fishes and invertebrates in an engaging and unique way that students and researchers in marine ecosystems will understand. Introduces a new paradigm, Predator-prey Synergism, as a building block on which to construct new ecological theories. It suggests that Predator-prey Synergism is important in some terrestrial ecosystems and is in agreement with the punctuated equilibria theory of evolution (i.e., stepwise evolution). Suggests a general solution to the recruitment puzzle in marine organisms Proposes a holistic hypothesis for marine spring blooming ecosystems by considering variability enhancing and variability dampening processes Asserts that fisheries will induce variability in marine ecosystems and alter the energy flow patterns in predictable ways
