In this book, noted biologist Eric Charnov uses ideas about symmetry, invariance, and scaling laws to explain many formerly puzzling regularities in population biology. Aspects of life history evolution and population dynamics are illuminated by his synthesis of symmetry and symmetry-breaking arguments. For example, he develops sex allocation evolution to reveal how symmetry-breaking leads to biased sex ratios, and also demonstrates how the process plays an important role in the evolution of alternative male life histories. A detailed evolutionary theory is developed and tested for the allometric structure of life histories in female mammals. The symmetry perspective is also applied to studies of aging as well as to the study of allometry in population dynamics. This work will attract interest among a wide range of students and researchers in ecology, evolution, behavior, and other fields within organismal biology.

In this text, Eric Charnov uses ideas about symmetry, invariance, and scaling laws to explore aspects of population dynamics and the evolution of male and female life histories. Charnov's work is internationally known and will attract great interest among postgraduate students and researchers in ecology, evolution, behaviour, and many other fields within organismal biology.

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.

The Ache, whose life history the authors recounts, are a small indigenous population of hunters and gatherers living in the neotropical rainforest of eastern Paraguay. This is part exemplary ethnography of the Ache and in larger part uses this population to make a signal contribution to human evolutionary ecology.

The social sciences share a mission to shed light on human nature and society. However, there is no widely accepted meta-theory; no foundation from which variables can be linked, causally sequenced, or ultimately explained. This book advances “life history evolution” as the missing meta-theory for the social sciences. Originally a biological theory for the variation between species, research on life history evolution now encompasses psychological and sociological variation within the human species that has long been the stock and trade of social scientific study. The eighteen chapters of this book review six disciplines, eighteen authors, and eighty-two volumes published between 1734 and 2015—re-reading the texts in the light of life history evolution.

This book is the first comprehensive treatment of sex allocation from the standpoint of modern evolutionary theory. It shows how the determination of sex ratio, resource allocation to sperm versus egg within simultaneous hermaphroditism, and the evolution of sex reversal can he explained as examples of a single process. The genetical theory, developed mostly with graphical arguments, also specifies when hermaphroditism and dioecy are themselves evolutionary stable. The work balances theory with field and laboratory research, providing critical tests of the theory by empirical studies of sex ratio in parasitoid wasps and mites, sex reversal in shrimp and coral reef fish, and allocation of resources to pollen versus seeds in higher plants. In addition, the author oilers an encyclopedic review of the field and laboratory work of other scientists, reviews many as yet untested hypotheses in sex allocation, and points toward numerous plant and animal systems that hold promise for future tests.

This major reference is an overview of the current state of theoretical ecology through a series of topical entries centered on both ecological and statistical themes. Coverage ranges across scales—from the physiological, to populations, landscapes, and ecosystems. Entries provide an introduction to broad fields such as Applied Ecology, Behavioral Ecology, Computational Ecology, Ecosystem Ecology, Epidemiology and Epidemic Modeling, Population Ecology, Spatial Ecology and Statistics in Ecology. Others provide greater specificity and depth, including discussions on the Allee effect, ordinary differential equations, and ecosystem services. Descriptions of modern statistical and modeling approaches and how they contributed to advances in theoretical ecology are also included. Succinct, uncompromising, and authoritative—a "must have" for those interested in the use of theory in the ecological sciences.

We know a great deal about roles the environment plays in shaping survival, reproductive success, and even social systems among primates. But how do primate life histories affect social systems and vice versa? Do baboons' patterns of growth, for example, help to structure their societies? Does fission-fusion sociality interact with predator pressure to influence the timing of maturation in chimpanzees? Exploring these issues and many others, the contributors to Primate Life Histories and Socioecology provide the first systematic attempt to understand relationships among primate life histories, ecology, and social behavior conjointly. Topics covered include how primate life histories interact with rates of evolution, predator pressure, and diverse social structures; how the slow maturation of primates affects the behavior of both young and adult caregivers; and reciprocal relationships between large brains and increased social and behavioral complexity. The first collection of its kind, this book will interest a wide range of researchers, from anthropologists and evolutionary biologists to psychologists and ecologists.
