This book was released on 2017-02-08 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword: "Predator-prey interactions are among the most significant of all organism-organism interactions....It will only be by compiling and evaluating data on predator-prey relations as they are recorded in the fossil record that we can hope to tease apart their role in the tangled web of evolutionary interaction over time. This volume, compiled by a group of expert specialists on the evidence of predator-prey interactions in the fossil record, is a pioneering effort to collate the information now accumulating in this important field. It will be a standard reference on which future study of one of the central dynamics of ecology as seen in the fossil record will be built." (Richard K. Bambach, Professor Emeritus, Virginia Tech, Associate of the Botanical Museum, Harvard University)

Available in PDF, EPUB and Kindle. Book excerpt: This thesis consists of two projects looking at different aspects of predatorprey relationships. The first project examines this relationship in the context of predator-prey coevolution and assumes that the cost for prey defense is variable. The second project looks at ecosystem shifts in the 1990s in the Gulf of Maine and the relative role of top-down verses bottom-up processes on controlling Calanus finmarchicus abundance. Predator-Prey Coevolution Predation can act as a selective pressure which drives prey to adapt a defensive trait to avoid attack. At the same time, predators can evolve a counter-defense which aids them in continued successful attacks. Allocation towards either trait can be costly, in the form of a decrease in fecundity. There is some evidence to suggest that, for the prey at least, cost can vary depending on the level of intraspecific competition. Here we investigated the effects of variable prey trait cost and genetic variability of the predator and prey, on the stability and dynamics of the system. We compared two models, one which assumed that cost of prey defense is fixed, and one that assumed that cost varies proportional to population density. We found that under most conditions, variable cost of prey defense is more stabilizing to the interaction than fixed cost. Gulf of Maine Ecosystem In the Gulf of Maine in the 1990s an increase in freshwater was associated with increased phytoplankton blooms, particularly in autumn. This in turn led to increased abundance in most copepods. Calanus finmarchicus, one of the most abundant zooplankton species in the region, demonstrated an increase in abundance in the earlier developmental stages but a paradoxical decrease in abundance of the later copepodid stages. At the same time, adult herring, which preferentially feed on late-stage C. finmarchicus, increased in abundance by one order of magnitude. Through ordinary differential equation models, we investigated whether increased presence of herring in the 1990s was large enough to contribute to the decline in late-stage C. finmarchicus. Additionally, we incorporated food-dependent growth into the later copepodid classes to investigate the impact of phytoplankton variation on the observed shifts in zooplankton abundance.

Book excerpt: Predator-prey interactions are ubiquitous, govern the flow of energy up trophic levels, and strongly influence the structure of ecological systems. They are typically quantified using the functional response - the relationship between a predator's foraging rate and the availability of food. As such, the functional response is central to how all ecological communities function - since all communities contain foragers - and a principal driver of the abundance, diversity, and dynamics of ecological communities. The functional response also reflects all the behaviors, traits, and strategies that predators use to hunt prey and that prey use to evade predation. It is thus both a clear reflection of past evolution, including predator-prey arms races, and a major force driving the future evolution of both predator and prey. Despite their importance, there have been remarkably few attempts to synthesize or even briefly review functional responses. This novel and accessible book fills this gap, clearly demonstrating their crucial role as the link between individuals, evolution, and community properties, representing a highly-integrated and measurable aspect of ecological function. It provides a clear entry point for students, a refresher for more advanced researchers, and a motivator for future research. Predator Ecology is an advanced textbook suitable for graduate students and researchers in ecology and evolutionary biology seeking a broad, up-to-date, and authoritative coverage of the field. It will also be of relevance and use to mathematical ecologists, wildlife biologists, and anyone interested in predator-prey interactions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Interactions between predator and prey can drive the evolution and diversification of nervous systems in astonishing ways. At the 2014 Karger Workshop, emerging leaders in the field presented highlights of some of the most compelling examples of co-evolved and specialized predators and prey. This subsequent special issue of 'Brain, Behavior and Evolution' includes discussions on neurotoxins, ion channels, visual systems, auditory localization, muscle activation, and echolocation. The species and questions addressed are equally diverse: How do alligators and owls localize sounds? What do two bats do when chasing the same insect? Why do some newts carry enough neurotoxin to kill twenty humans? What rules govern killer fly attack behavior? How do electric eels remotely control prey? Why are beautiful cone snails a potential cornucopia of pharmaceuticals? Overall, this publication provides valuable insight into why predator-prey interactions hold a special place in the study of biology and evolution.

Download or read book Bats written by Heimo Mikkola and published by BoD – Books on Demand. This book was released on 2018-07-04 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bats have a poor image for the public at large because they are often feared. This is usually due to ignorance. In this book, we have eight chapters on bats covering countries such as Algeria, Bulgaria, France, Pakistan, Poland, the UK and the USA and subjects ranging from acoustic monitoring of bat species for distribution and conservation purposes to various bat-borne and bat-carried diseases. These diseases cannot be taken lightly but should not be a reason for panic or to fear or even kill bats. Bats will not cause any harm if we let them live in peace. With the added knowledge through this book, we should know how best to cope with bats, which need all our support in the changing environments and climates.

Available in PDF, EPUB and Kindle. Book excerpt: Can we can use the patterns and processes of convergent evolution to make inferences about universal laws of life, on Earth and elsewhere? In this book, Russell Powell investigates whether we can use the patterns and processes of convergent evolution to make inferences about universal laws of life, on Earth and elsewhere. Weaving together disparate philosophical and empirical threads, Powell offers the first detailed analysis of the interplay between contingency and convergence in macroevolution, as it relates to both complex life in general and cognitively complex life in particular. If the evolution of mind is not a historical accident, the product of convergence rather than contingency, then, Powell asks, is mind likely to be an evolutionarily important feature of any living world? Stephen Jay Gould argued for the primacy of contingency in evolution. Gould's “radical contingency thesis” (RCT) has been challenged, but critics have largely failed to engage with its core claims and theoretical commitments. Powell fills this gap. He first examines convergent regularities at both temporal and phylogenetic depths, finding evidence that both vindicates and rebuffs Gould's argument for contingency. Powell follows this partial defense of the RCT with a substantive critique. Among the evolutionary outcomes that might defy the RCT, he argues, cognition is particularly important—not only for human-specific issues of the evolution of intelligence and consciousness but also for the large-scale ecological organization of macroscopic living worlds. Turning his attention to complex cognitive life, Powell considers what patterns of cognitive convergence tell us about the nature of mind, its evolution, and its place in the universe. If complex bodies are common in the universe, might complex minds be common as well?

Download or read book Interaction and Coevolution written by John N. Thompson and published by University of Chicago Press. This book was released on 2014-02-14 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: “It is not only the species that change evolutionarily through interactions . . . the interactions themselves also change.” Thus states John N. Thompson in the foreword to Interaction and Coevolution, the first title in his series of books exploring the relentless nature of evolution and the processes that shape the web of life. Originally published in 1982 more as an idea piece—an early attempt to synthesize then academically distinct but logically linked strands of ecological thought and to suggest avenues for further research—than as a data-driven monograph, Interaction and Coevolution would go on to be considered a landmark study that pointed to the beginning of a new discipline. Through chapters on antagonism, mutualism, and the effects of these interactions on populations, speciation, and community structure, Thompson seeks to explain not only how interactions differ in the selection pressures they exert on species, but also when interactions are most likely to lead to coevolution. In this era of climate change and swiftly transforming environments, the ideas Thompson puts forward in Interaction and Coevolution are more relevant than ever before.
