This book addresses the fundamental issues of predator-prey interactions, with an emphasis on predation among arthropods, which have been better studied, and for which the database is more extensive than for the large and rare vertebrate predators. The book should appeal to ecologists interested in the broad issue of predation effects on communities.

Unbeknownst to the colonists on Ryushi, the planet is the setting for hunting games between the Predators and the prey they have bred for this purpose, and Machiko Noguchi and the other ranchers must fight for survival.

Who is the predator, and who is the prey? Illuminating poetry and vivid artwork capture the awe-inspiring ways that creatures use their resources to stay alive. Who wins, the assassin bug or the spider? The bat or the frog? The ant or the honey bee? The male firefly . . . or the female? The battle for survival between predator and prey is sometimes a fight, sometimes a dance, and often involves spying, lying, or even telling the truth to get ahead. Biologist and debut author Susannah Buhrman-Deever explores these clashes in poems and prose explanations that offer both sides of the story. With beautiful, realistic illustrations that are charged with drama, Bert Kitchen captures the breathtaking moments when predator meets prey. Readers who hunger for more about the art of survival will find an extensive list of references in the back.

Humans, being visually oriented, are well versed in camouflage and how animals hide from predators that use vision to locate prey. However, many predators do not hunt by sight; they hunt by scent. This raises the question: do survival mechanisms and behaviors exist which allow animals to hide from these olfactory predators? If so, what are they, and how do they work? Predator-Prey Dynamics: The Role of Olfaction examines environmental as well as biological and behavioral elements of both predators and prey to answer gaps in our current knowledge of the survival dynamics of species. Beginning with a thorough look at the mechanics of olfaction, the author explains how predators detect, locate, and track their prey using odor trails on the ground or odor plumes in the air. Understanding the physics of airflow is the next step to understanding the potential for manipulating and masking scent. While a bush may conceal an animal visually from a predator, it will not protect an animal from a predator using olfaction. To hide from the latter, an animal needs to hide in locations where turbulence and updrafts will disperse its scent. The book addresses tradeoffs that animals must make given their dual needs to hide from predators and to procure food and water. Studies of mammalian and avian behavior provide examples on the actual use and efficacy of olfactory camouflage tactics. The book concludes with a redefinition of ecological terms based on the physics of airflow and a summary of the theory and implications of olfactory predator--prey dynamics. Introducing the mechanics of olfaction and its influence on the behavior of both predators and prey, Predator-Prey Dynamics: The Role of Olfaction presents a new perception of the world and enables us to understand and more effectively manage the delicate survival dynamics of animals in the wild.

This book provides a comprehensive review of the evolution of traits associated with predation and predator defense for bats and all of their prey, both invertebrates (e.g. insects) and vertebrates (e.g. frogs), in the context of co-evolution. It reviews current knowledge of how echolocation and passive hearing are used by bats to hunt prey in complete darkness. Also it highlights how prey have evolved counter measures to bat echolocation to avoid detection and capture. This includes the whole range of prey responses from being active at times when bats are inactive to the use of acoustic signals of their own to interfere with the echolocation system of bats.

After centuries of peace, the Imperium is thrown into panic as human worlds everywhere are menaced by orks. After centuries of peace, the Imperium is thrown into panic as human worlds everywhere are menaced by orks. In a relentless tide of slaughter, ork attack moons destroy planet after planet with gravity weapons of unstoppable power. On Terra, the High Lords are paralysed by the scale of the threat, and fail to take any effective action. With entire Space Marine Chapters missing, or known to have been wiped out, does anyone have the will and the power to rise to the Imperium’s defence?

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
