This book was released on 2020-03-31 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Florida Scrub Jays are an excellent example of a cooperative-breeding species, in which adult birds often help raise offspring not their own. For more than a decade Glen E. Woolfenden and John W. Fitzpatrick studied a marked population of these birds in an attempt to establish a demographic base for understanding the phenomenon of "helping at the nest." By studying both population biology and behavior, the authors found that habitat restraints, rather than kin selection, are the main source of the behavior of Florida Scrub Jays: the goal of increasing the number of close relatives other than descendants in future generations is of relatively minor importance in their cooperative-breeding behavior. The Florida Scrub Jay lives only in the Florida oak scrub. All acceptable habitat is constantly filled with breeders. Each year about half of the pairs are assisted by one to several nonbreeding helpers. This book provides extensive data on fecundity, survivorship, relatedness, and dispersal to establish the demographic milieu and to address questions arising out of observed helping behavior--whom, how, when, and why the helpers help.
Book Synopsis Natural Selection in the Wild. (MPB-21), Volume 21 by : John A. Endler
Download or read book Natural Selection in the Wild. (MPB-21), Volume 21 written by John A. Endler and published by Princeton University Press. This book was released on 2020-03-31 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural selection is an immense and important subject, yet there have been few attempts to summarize its effects on natural populations, and fewer still which discuss the problems of working with natural selection in the wild. These are the purposes of John Endler's book. In it, he discusses the methods and problems involved in the demonstration and measurement of natural selection, presents the critical evidence for its existence, and places it in an evolutionary perspective. Professor Endler finds that there are a remarkable number of direct demonstrations of selection in a wide variety of animals and plants. The distribution of observed magnitudes of selection in natural populations is surprisingly broad, and it overlaps extensively the range of values found in artificial selection. He argues that the common assumption that selection is usually weak in natural populations is no longer tenable, but that natural selection is only one component of the process of evolution; natural selection can explain the change of frequencies of variants, but not their origins.
Book Synopsis A Hierarchical Concept of Ecosystems. (MPB-23), Volume 23 by : Robert V. O'Neill
Download or read book A Hierarchical Concept of Ecosystems. (MPB-23), Volume 23 written by Robert V. O'Neill and published by Princeton University Press. This book was released on 2021-09-14 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Ecosystem" is an intuitively appealing concept to most ecologists, but, in spite of its widespread use, the term remains diffuse and ambiguous. The authors of this book argue that previous attempts to define the concept have been derived from particular viewpoints to the exclusion of others equally possible. They offer instead a more general line of thought based on hierarchy theory. Their contribution should help to counteract the present separation of subdisciplines in ecology and to bring functional and population/community ecologists closer to a common approach. Developed as a way of understanding highly complex organized systems, hierarchy theory has at its center the idea that organization results from differences in process rates. To the authors the theory suggests an objective way of decomposing ecosystems into their component parts. The results thus obtained offer a rewarding method for integrating various schools of ecology.
Book Synopsis Population Ecology of the Cooperatively Breeding Acorn Woodpecker. (MPB-24), Volume 24 by : Walter D. Koenig
Download or read book Population Ecology of the Cooperatively Breeding Acorn Woodpecker. (MPB-24), Volume 24 written by Walter D. Koenig and published by Princeton University Press. This book was released on 2020-03-31 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the acorn woodpecker was observed and described by Spanish explorers, its behavior--particularly the unique habit of caching acorns in specialized storage trees or granaries--has impressed observers. Acorn woodpeckers are also one of the few temperate zone species in which young are reared communally in family groups. This demographic study investigates the complexities of acorn storage and group living in acorn woodpeckers at Hastings Reservation in central coastal California. It is one of the most thorough studies of any avian social system to date.
Book Synopsis Population Ecology of Individuals. (MPB-25), Volume 25 by : Adam Lomnicki
Download or read book Population Ecology of Individuals. (MPB-25), Volume 25 written by Adam Lomnicki and published by Princeton University Press. This book was released on 2020-03-31 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common tendency in the field of population ecology has been to overlook individual differences by treating populations as homogeneous units; conversely, in behavioral ecology the tendency has been to concentrate on how individual behavior is shaped by evolutionary forces, but not on how this behavior affects population dynamics. Adam Lomnicki and others aim to remedy this one-sidedness by showing that the overall dynamical behavior of populations must ultimately be understood in terms of the behavior of individuals. Professor Lomnicki's wide-ranging presentation of this approach includes simple mathematical models aimed at describing both the origin and consequences of individual variation among plants and animals. The author contends that further progress in population ecology will require taking into account individual differences other than sex, age, and taxonomic affiliation--unequal access to resources, for instance. Population ecologists who adopt this viewpoint may discover new answers to classical questions of population ecology. Partly because it uses a variety of examples from many taxonomic groups, this work will appeal not only to population ecologists but to ecologists in general.
Book Synopsis Geographic Variation, Speciation and Clines. (MPB-10), Volume 10 by : John A. Endler
Download or read book Geographic Variation, Speciation and Clines. (MPB-10), Volume 10 written by John A. Endler and published by Princeton University Press. This book was released on 2020-03-31 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geographic Variation, Speciation and Clines explores the origins and development of geographic variation, divergence, and speciation. In particular it is concerned with genetic divergence as it is usually found on continents, among groups of populations isolated only by distance. Although earlier writers on this topic considered the effects of geography and dispersal, intense geographic differentiation and speciation were thought to require complete isolation. Professor Endler shows how geographic differentiation and speciation may develop in spite of continuous gene flow. Following a review of the diverse and scattered literature on gene flow and population differentiation, the author discusses the relationships among gene flow, dispersal, and migration. He then summarizes the factors which limit the geographic extent of gene flow, and those which allow steep clines to develop in the absence of barriers to gene flow. His analysis draws on examples from the field, experiments, and single- and multiple-locus models. The mechanism and conditions for parapatric speciation are presented: steepening clines, development into hybrid zones, and the evolution of sexual isolation. In the final chapter the author considers the interpretation of natural clines and the associated geographic patterns of subspecies and species.
Book Synopsis Theoretical Studies on Sex Ratio Evolution. (MPB-22), Volume 22 by : Samuel Karlin
Download or read book Theoretical Studies on Sex Ratio Evolution. (MPB-22), Volume 22 written by Samuel Karlin and published by Princeton University Press. This book was released on 2020-03-31 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a key area of population genetics: the ratio of the sexes in a population, or the allocation of resources to male versus female reproductive function. Samuel Karlin and Sabin Lessard establish the formal theoretical aspects of the evolution of sex ratio within the constraints of genetic mechanisms of sex determination. Their results generalize and unify existing work on the topic, strengthening previous conceptions in some cases and, in other instances, offering new directions of research. There are two main approaches to understanding the causes and effects of sex ratio. One approach focuses on the optimization and adaptive functions of sex allocation, while the other emphasizes the consequences of genetic sex determination mechanisms. In discussing the utility of these two approaches, Professors Karlin and Lessard examine the principal sex-determining mechanisms and facts involved in sex ratio representations, the various genetic and environmental factors that contribute to adaptive sex expression, and the evolution of sex determining systems and controls. From a population genetic perspective, the authors derive evolutionary properties in support of the high incidence of 1:1 sex ratio in natural populations and investigate the conditions that can explain the occurrence of biased sex ratio.
Book Synopsis Population Harvesting (MPB-27), Volume 27 by : Wayne M. Getz
Download or read book Population Harvesting (MPB-27), Volume 27 written by Wayne M. Getz and published by Princeton University Press. This book was released on 2020-03-31 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whether in felling trees for wood, rearing insects for biological control, or culling animals for conservation purposes, efficient management of biological systems requires quantitative analysis of population growth and harvesting policies. Aiming to encourage the exchange of ideas among scientists involved in the management of fisheries, wildlife, forest stands, and pest control, the authors of this work present a general framework for modeling populations that reproduce seasonally and that have age or stage structure as an essential component of management strategy. The book represents the first time that examples from such diverse areas of biological resource management have been brought together in a unified modeling framework using the standard notation of mathematical systems theory. In addition, the authors combine a nonlinear extension of Leslie matrix theory and certain linear elements, thereby permitting interesting analytical results and the creation of compact, realistic simulation models of resource systems.
Book Synopsis Plant Strategies and the Dynamics and Structure of Plant Communities. (MPB-26), Volume 26 by : David Tilman
Download or read book Plant Strategies and the Dynamics and Structure of Plant Communities. (MPB-26), Volume 26 written by David Tilman and published by Princeton University Press. This book was released on 2020-03-31 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although ecologists have long considered morphology and life history to be important determinants of the distribution, abundance, and dynamics of plants in nature, this book contains the first theory to predict explicitly both the evolution of plant traits and the effects of these traits on plant community structure and dynamics. David Tilman focuses on the universal requirement of terrestrial plants for both below-ground and above-ground resources. The physical separation of these resources means that plants face an unavoidable tradeoff. To obtain a higher proportion of one resource, a plant must allocate more of its growth to the structures involved in its acquisition, and thus necessarily obtain a lower proportion of another resource. Professor Tilman presents a simple theory that includes this constraint and tradeoff, and uses the theory to explore the evolution of plant life histories and morphologies along productivity and disturbance gradients. The book shows that relative growth rate, which is predicted to be strongly influenced by a plant's proportional allocation to leaves, is a major determinant of the transient dynamics of competition. These dynamics may explain the differences between successions on poor versus rich soils and suggest that most field experiments performed to date have been of too short a duration to allow unambiguous interpretation of their results.

Book Synopsis The Coastal Everglades by : Daniel L. Childers
Download or read book The Coastal Everglades written by Daniel L. Childers and published by Oxford University Press, USA. This book was released on 2019 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Coastal Everglades presents a broad overview and synthesis of research on the coastal Everglades, a region that includes Everglades National Park, adjacent managed wetlands, and agricultural and urbanizing communities. Contributors for this volume are all collaborators on the Florida Coastal Everglades Long-Term Ecological Research Program (FCE LTER). The FCE LTER began in 2000 with a focus on understanding key ecosystem processes in the coastal Everglades, while also developing a platform for and linkages to related work conducted by an active and diverse Everglades research community. The program is based at Florida International University in Miami, but includes scientists and students from numerous other universities as well as staff scientists at key resource management agencies, including Everglades National Park and the South Florida Water Management District. Though the Everglades landscape spans nearly a third of the State of Florida, the focus on the coastal Everglades has allowed the contributors to examine key questions in social-ecological science in the context of ongoing restoration initiatives. As this book demonstrates, the long-term research of the FCE LTER has facilitated a better understanding of the roles of sea level rise, water management practices, urban and agricultural development, and other disturbances, such as fires and storms, on the past and future dynamics of this unique coastal environment. By comparing properties of the Everglades with other subtropical and tropical wetlands, the book challenges ideas of novelty while revealing properties of ecosystems at the ends of gradients that are often ignored. It also provides insights from, and encouragement for, long-term collaborative studies that inform resource management in similarly threatened coastal wetland landscapes.

This book was released on 2020-09-15 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plethora of different theories, models, and concepts make up the field of community ecology. Amid this vast body of work, is it possible to build one general theory of ecological communities? What other scientific areas might serve as a guiding framework? As it turns out, the core focus of community ecology—understanding patterns of diversity and composition of biological variants across space and time—is shared by evolutionary biology and its very coherent conceptual framework, population genetics theory. The Theory of Ecological Communities takes this as a starting point to pull together community ecology's various perspectives into a more unified whole. Mark Vellend builds a theory of ecological communities based on four overarching processes: selection among species, drift, dispersal, and speciation. These are analogues of the four central processes in population genetics theory—selection within species, drift, gene flow, and mutation—and together they subsume almost all of the many dozens of more specific models built to describe the dynamics of communities of interacting species. The result is a theory that allows the effects of many low-level processes, such as competition, facilitation, predation, disturbance, stress, succession, colonization, and local extinction to be understood as the underpinnings of high-level processes with widely applicable consequences for ecological communities. Reframing the numerous existing ideas in community ecology, The Theory of Ecological Communities provides a new way for thinking about biological composition and diversity.
Book Synopsis Scaling in Ecology with a Model System by : Aaron M. Ellison
Download or read book Scaling in Ecology with a Model System written by Aaron M. Ellison and published by Princeton University Press. This book was released on 2021-08-03 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Scale - the understanding of ecological phenomena through levels of biological organization across time and space - is one of most important concepts in ecology. It is often challenging for ecologists to find systems that lend themselves to study across scales; however, Sarracenia, a pitcher plant indigenous to the eastern United States, is unique because it can be studied at a hierarchy of scales: individuals, communities, and whole ecosystems. Ecologists Aaron Ellison and Nicolas Gotelli have studied Sarracenia for decades and, in this book, they synthesize their research and show how this system can inform the broad and challenging question of scaling in ecology. The authors' goal is to deepen the current understanding of major ecological processes, and how they operate across scales"--
Book Synopsis Coexistence in Ecology by : Mark A. McPeek
Download or read book Coexistence in Ecology written by Mark A. McPeek and published by Princeton University Press. This book was released on 2022-02-08 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive framework for understanding species coexistence Coexistence is the central concept in community ecology, but an understanding of this concept requires that we study the actual mechanisms of species interactions. Coexistence in Ecology examines the major features of these mechanisms for species that coexist at different positions in complex food webs, and derives empirical tests from model predictions. Exploring the various challenges species face, Mark McPeek systematically builds a model food web, beginning with an ecosystem devoid of life and then adding one species at a time. With the introduction of each new species, he evaluates the properties it must possess to invade a community and quantifies the changes in the abundances of other species that result from a successful invasion. McPeek continues this process until he achieves a multitrophic level food web with many species coexisting at each trophic level, from omnivores, mutualists, and pathogens to herbivores, carnivores, and basic plants. He then describes the observational and experimental empirical studies that can test the theoretical predictions resulting from the model analyses. Synthesizing decades of theoretical research in community ecology, Coexistence in Ecology offers new perspectives on how to develop an empirical program of study rooted in the natural histories of species and the mechanisms by which they actually interact with one another.
