Book Description
Life histories can be defined as the means by which individuals (or more precisely genotypes) vary their age- or stage-specific expenditures of reproductive effort in response to genetic, phenotypic, and environmental correlates of survival and fecundity. Life histories reflect the expression of traits most closely related to individual fitness, such as age and size at maturity, number and size of offspring, and the timing of the expression of those traits throughout an individual's life. In addition to addressing questions of fundamental importance to ecology and evolution, life-history research plays an integral role in species conservation and management. This accessible primer encompasses the basic concepts, theories, and applied elements of life history evolution, including patterns of trait variability, underlying mechanisms of plastic/evolutionary change, and the practical utility of life-history traits as metrics of species/population recovery, sustainable exploitation, and risk of extinction. Empirical examples are drawn from the entire spectrum of life. A Primer of Life Histories is designed for readers from a broad range of academic backgrounds and experience including graduate students and researchers of ecology and evolutionary biology. It will also be useful to a more applied audience of academic/government researchers in fields such as wildlife biology, conservation biology, fisheries science, and the environmental sciences.

Book Description
Crustaceans are increasingly being used as model organisms in all fields of biology, including neurobiology, developmental biology, animal physiology, evolutionary ecology, biogeography, and resource management. Crustaceans have a very wide range of phenotypes and inhabit a diverse array of environments, ranging from the deep sea to high mountain lakes and even deserts. The evolution of their life histories has permitted crustaceans to successfully colonize this variety of habitats. Few other taxa exhibit such a variety of life histories and behavior. A comprehensive overview of their life histories is essential to the understanding of many aspects of their success in marine and terrestrial environments. This volume provides a general overview of crustacean life histories. Crustaceans have particular life history adaptations that have permitted them to conquer all environments on earth. Crustacean life cycles have evolved to maximize fecundity, growth, and ageing, in a wide range of environmental conditions. Individual contributions contrast benefits and costs of different life histories including sexual versus asexual production, semelparity versus iteroparity, and planktonic larvae versus direct development. Important aspects of particular behaviors are presented (e.g. migrations, defense and territorial behaviors, anti-predator behavior, symbiosis).

Book Description
In recent years researchers have discovered that bats play key roles in many ecosystems as insect predators, seed dispersers, and pollinators. Bats also display astonishing ecological and evolutionary diversity and serve as important models for studies of a wide variety of topics, including food webs, biogeography, and emerging diseases. In Bat Ecology, world-renowned bat scholars present an up-to-date, comprehensive, and authoritative review of this ongoing research. The first part of the book covers the life history and behavioral ecology of bats, from migration to sperm competition and natural selection. The next section focuses on functional ecology, including ecomorphology, feeding, and physiology. In the third section, contributors explore macroecological issues such as the evolution of ecological diversity, range size, and infectious diseases (including rabies) in bats. A final chapter discusses conservation challenges facing these fascinating flying mammals. Bat Ecology is the most comprehensive state-of-the-field collection for scientists and researchers.

Book Description
This book supplies the evolutionary and genetic framework that Charles Murray, towards the end of Coming Apart: The State of White America 1960-2010, predicts will one day explain revolutionary change in American society. Murray’s Coming Apart documents 50 years of changed college admissions, government incentives, mating and migration patterns that have wrought national divisions across indexes of marriage, industriousness, honesty, and religiosity. The framework discussed is life history evolution, a sub-discipline within evolutionary biology singly capable of explaining why violent crime, property crime, low marriage rates, father absence, early birth, low educational achievement, low income, poverty, lack of religiosity and reduced achievement striving will reliably co-occur as part of a complex. This complex augments facultatively, developmentally and evolutionarily in response to unpredictable and uncontrollable sources of mortality. The uncertain tenure of life wrought by unpredictable and uncontrollable mortality selects for a present-oriented use of bioenergetics resources recognizable as the social ills of Fishtown, Murray’s archetypal working class community. In turn, the thirty years of life history literature herein reviewed confirms the biological logic of elite intermarriage and sequestration. The source of life history variation, policy implications, and demography are discussed.

Book Description
“One of our true superstars of nonfiction” (David Foster Wallace), Lewis Hyde offers a playful and inspiring defense of forgetfulness by exploring the healing effect it can have on the human psyche. We live in a culture that prizes memory—how much we can store, the quality of what’s preserved, how we might better document and retain the moments of our life while fighting off the nightmare of losing all that we have experienced. But what if forgetfulness were seen not as something to fear—be it in the form of illness or simple absentmindedness—but rather as a blessing, a balm, a path to peace and rebirth? A Primer for Forgetting is a remarkable experiment in scholarship, autobiography, and social criticism by the author of the classics The Gift and Trickster Makes This World. It forges a new vision of forgetfulness by assembling fragments of art and writing from the ancient world to the modern, weighing the potential boons forgetfulness might offer the present moment as a creative and political force. It also turns inward, using the author’s own life and memory as a canvas upon which to extol the virtues of a concept too long taken as an evil. Drawing material from Hesiod to Jorge Luis Borges to Elizabeth Bishop to Archbishop Desmond Tutu, from myths and legends to very real and recent traumas both personal and historical, A Primer for Forgetting is a unique and remarkable synthesis that only Lewis Hyde could have produced.

Book Description
This book covers basic concepts in population and quantitative genetics, including measuring selection on phenotypic traits. The emphasis is on material applicable to field studies of evolution focusing on ecologically important traits. Topics addressed are critical for training students in ecology, evolution, conservation biology, agriculture, forestry, and wildlife management. Many texts in this field are too complex and mathematical to allow the average beginning student to readily grasp the key concepts. A Primer of Ecological Genetics, in contrast, employs mathematics and statistics-fully explained, but at a less advanced level-as tools to improve understanding of biological principles. The main goal is to enable students to understand the concepts well enough that they can gain entry into the primary literature. Integration of the different chapters of the book shows students how diverse concepts relate to each other.

Book Description
Life history theory seeks to explain the evolution of the major features of life cycles by analyzing the ecological factors that shape age-specific schedules of growth, reproduction, and survival and by investigating the trade-offs that constrain the evolution of these traits. Although life history theory has made enormous progress in explaining the diversity of life history strategies among species, it traditionally ignores the underlying proximate mechanisms. This novel book argues that many fundamental problems in life history evolution, including the nature of trade-offs, can only be fully resolved if we begin to integrate information on developmental, physiological, and genetic mechanisms into the classical life history framework. Each chapter is written by an established or up-and-coming leader in their respective field; they not only represent the state of the art but also offer fresh perspectives for future research. The text is divided into 7 sections that cover basic concepts (Part 1), the mechanisms that affect different parts of the life cycle (growth, development, and maturation; reproduction; and aging and somatic maintenance) (Parts 2-4), life history plasticity (Part 5), life history integration and trade-offs (Part 6), and concludes with a synthesis chapter written by a prominent leader in the field and an editorial postscript (Part 7).
