Mothers have the ability to profoundly affect the quality of their offspring--from the size and quality of their eggs to where, when, and how eggs and young are placed, and from providing for and protecting developing young to choosing a mate. In many instances, these maternal effects may be the single most important contributor to variation in offspring fitness. This book explores the wide variety of maternal effects that have evolved in plants and animals as mechanisms of adaptation to temporally and spatially heterogeneous environments. Topics range from the evolutionary implications of maternal effects to the assessment and measurement of maternal effects. Four detailed case studies are also included. This book represents the first synthesis of the current state of knowledge concerning the evolution of maternal effects and their adaptive significance.

presented in the Introduction (Chapter 1). The focus of Chapter 1 is twofold: (1) to present the research foundations for the psychophysiological correlates of prenatal psychosocial adaptation and the seven prenatal personality dimensions with progress in labor and birth outcomes, and particularly (2) to present the theory underlying the seven dimensions of prenatal psychosocial adaptation, which are further analyzed in the following seven chapters. Chapters 2–8 present a content analysis of the interview responses to the seven significant prenatal personality dimensions that are predictive of pregnancy adap- tion, progress in labor, birth outcomes, and postpartum maternal psychosocial adaptation, and they include: (1) Acceptance of Pregnancy, (2) Identification with a Motherhood Role, (3) Relationship with Mother, (4) Relationship with Husband, (5) Preparation for Labor, (6) (Prenatal) Fear of Pain, Helplessness, and Loss of Control in Labor, and (7) (Prenatal) Fear of Loss of Self-Esteem in Labor. There is no other comparable comprehensive, in-depth, prenatal personality research or empirical and content analysis of pregnancy-specific dimensions of maternal psychosocial adaptation to pregnancy.

Maternal nutritional status affects the offsprings health development significantly during early embryogenesis, pregnancy, birth and lactation, and subsequently determines health during growth and even throughout adulthood. On the other end of the human lifetime scale, the importance of maternal nutrition expands into the time period before conception: Pre-conception nutritional status not only influences fertility, but also embryogenesis and life-long health. Predisposition for coronary heart diseases, Type-2 diabetes mellitus, and hypertension can be caused by intrauterine adaptations to fetal malnutrition. Hence, optimizing nutrition for women during their reproductive period can be expected to have a great impact on the well being of the next generation. This workshop dealt with the effects of maternal nutrition on fetal growth, metabolic programming, energy and nutrient requirements, as well as under- and over-nutrition during pregnancy. Finally, it addressed the question of whether a distinct diet during pregnancy could reduce food allergy in the progeny. This book is a valuable and complete source of knowledge for all professionals involved in pediatrics, nutrition policy, womens health, immunology, epidemiology and public health.

All organisms live in clusters, but such fractured local populations, or demes, nonetheless maintain connectivity with one another by some amount of gene flow between them. Most such metapopulations occur naturally, like clusters of amphibians in vernal ponds or baboon troops spread across the African veldt. Others have been created as human activities fragment natural landscapes, as in stands of trees separated by roads. As landscape change has accelerated, understanding how these metapopulations function—and specifically how they adapt—has become crucial to ecology and to our very understanding of evolution itself. With Adaptation in Metapopulations, Michael J. Wade explores a key component of this new understanding of evolution: interaction. Synthesizing decades of work in the lab and in the field in a book both empirically grounded and underpinned by a strong conceptual framework, Wade looks at the role of interaction across scales from gene selection to selection at the level of individuals, kin, and groups. In so doing, he integrates molecular and organismal biology to reveal the true complexities of evolutionary dynamics from genes to metapopulations.

Evolutionary maternal effects occur whenever a mother’s phenotypic traits directly affect her offspring’s phenotype, independent of the offspring’s genotype. Some of the phenotypic traits that result in maternal effects have a genetic basis, whereas others are environmentally determined. For example, the size of a litter produced by a mammalian mother—a trait with a strong genetic basis—can affect the growth rate of her offspring, while a mother’s dominance rank—an environmentally determined trait—can affect the dominance rank of her offspring. The first volume published on the subject in more than a decade, Maternal Effects in Mammals reflects advances in genomic, ecological, and behavioral research, as well new understandings of the evolutionary interplay between mothers and their offspring. Dario Maestripieri and Jill M. Mateo bring together a learned group of contributors to synthesize the vast literature on a range of species, highlight evolutionary processes that were previously overlooked, and propose new avenues of research. Maternal Effects in Mammals will serve as the most comprehensive compendium on and stimulus for interdisciplinary treatments of mammalian maternal effects.

Since the very early stages of life, we all experience some form of stress. Stressors can be mild to severe and can range from unsuccessfully longing for maternal milk in infancy, to recklessly wiggling on a motorbike to be on time to watch the NBA finals on TV, to breaking up a relationship. All those events that we call “stress” have the capability of perturbing a given state of psychological and physiological equilibrium and moving it to a different level. The transition from crawling to walking has to be considered a form of stress as much as losing a job. It is through a continuous cross-talk between environmental stressors and individual adaptations that we build our personalities and our ways to cope with daily hassles. External challenges should not necessarily be regarded as “bad”, but instead seen as constructive forces forming our ability to navigate a changing world. What is stress good for? What is stress bad for? When and why do we need to be “stressed”? Should we worry about stress? When does stress equate to “normality”? When does it turn into pathology? We hope with this book to provide some answers to these fundamental questions.

Fitness and adaptation are fundamental characteristics of plant and animal species, enabling them to survive in their environment and to adapt to the inevitable changes in this environment. This is true for both the genetic resources of natural ecosystems as well as those used in agricultural production. Extensive genetic variation exists between varieties/breeds in a species and amongst individuals within breeds. This variation has developed over very long periods of time. A major ongoing challenge is how to best utilize this variation to meet short-term demands whilst also conserving it for longer-term possible use. Many animal breeding programs have led to increased performance for production traits but this has often been accompanied by reduced fitness. In addition, the global use of genetic resources prompts the question whether introduced genotypes are adapted to local production systems. Understanding the genetic nature of fitness and adaptation will enable us to better manage genetic resources allowing us to make efficient and sustainable decisions for the improvement or breeding of these resources. This book had an ambitious goal in bringing together a sample of the world’s leading scientists in animal breeding and evolutionary genetics to exchange knowledge to advance our understanding of these vital issues.

Clonality is widespread in plant species, and clonal plants often have a broad geographic range and long lifespan. Clonality can maintain high fitness in the short term, but vegetative reproduction is commonly considered to preclude adaptation to changing conditions. However, an increasing body of empirical and theoretical evidence suggests that epigenetic modifications such as DNA methylation can provide an alternative to gene-driven evolution through natural selection and allow clonal plants to maintain fitness in the long term. To deepen our understanding of clonal ecology, this collection of research papers and reviews focuses on how epigenetic regulation can encode phenotypic plasticity and contribute to the rapid adaptation of clonal plants to accelerating global and regional environmental changes.

Physiological Adaptations for Breeding in Birds is the most current and comprehensive account of research on avian reproduction. It develops two unique themes: the consideration of female avian reproductive physiology and ecology, and an emphasis on individual variation in life-history traits. Tony Williams investigates the physiological, metabolic, energetic, and hormonal mechanisms that underpin individual variation in the key female-specific reproductive traits and the trade-offs between these traits that determine variation in fitness. The core of the book deals with the avian reproductive cycle, from seasonal gonadal development, through egg laying and incubation, to chick rearing. Reproduction is considered in the context of the annual cycle and through an individual's entire life history. The book focuses on timing of breeding, clutch size, egg size and egg quality, and parental care. It also provides a primer on female reproductive physiology and considers trade-offs and carryover effects between reproduction and other life-history stages. In each chapter, Williams describes individual variation in the trait of interest and the evolutionary context for trait variation. He argues that there is only a rudimentary, and in some cases nonexistent, understanding of the physiological mechanisms that underpin individual variation in the major reproductive life-history traits, and that research efforts should refocus on these key unresolved problems by incorporating detailed physiological studies into existing long-term population studies, generating a new synthesis of physiology, ecology, and evolutionary biology.

Provides a broad snapshot of recent findings showing how the environment and genes influence behavior The great debate of nature versus nurture rages on — but our understanding of the genetic basis of many behaviors has expanded over the last decade, and there is now very good evidence showing that seemingly complex behaviours can have relatively simple genetic underpinnings, but also that most behaviours have very complicated genetic and environmental architecture. Studies have also clearly shown that behaviors, and other traits, are influenced not just by genes and the environment, but also by the statistical interaction between the two. This book aims to end the nature versus nurture argument by showing that behaviors are nature and nurture and the interaction between the two, and by illustrating how single genes can explain some of the variation in behaviors even when they are seemingly complex. Genes and Behaviour: Beyond Nature-Nurture puts to rest the nature versus nurture dichotomy, providing an up-to-date synopsis of where we are, how far we've come and where we are headed. It considers the effects of a dual-inheritance of genes and culture, and genes and social environment, and highlights how indirect genetic effects can affect the evolution of behavior. It also examines the effect of non-self genes on the behavior of hosts, shines a light on the nature and nurturing of animal minds and invites us to embrace all the complexity nature and nurture generates, and more. Explores exciting new findings about behavior and where we go from here Features contributions by top scholars of the subject Seeks to end the nature versus nurture debate forever Genes and Behaviour: Beyond Nature-Nurture is a unique, and eye-opening read that will appeal to Ph.D. Students, post-doctoral fellows, and researchers in evolution and behavior. Additionally, the book will also be of interest to geneticists, sociologists and philosophers.
