Darwin's theory of sexual selection fundamentally changed how we think about sex and
evolution. The struggle over mating and fertilization is a powerful driver of diversification …

Rapid divergence and speciation can occur between populations with or without ecological
differences under selection for success in intraspecific social competition-competition in …

Abstract In this book, Eric Charnov uses ideas about symmetry, invariance, and scaling laws
to explore aspects of population dynamics and the evolution of male and female life …

Sex is as fascinating to scientists as it is to the rest of us. A vast pool of knowledge, therefore,
has been gleaned from research into the nature of sex, from the contentious problem of why …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

Social behavior holds a special position among natural phenomena in relation to the
Darwinian theory of organic evolution. When individuals of the same species live in close …

This paper is a review of the effects of stress on reproduction in fishes. I hope to further the
development of the concepts of allostasis and hormesis as relevant to understanding …

Organisms compete for various resources in the course of sexual reproduction. First, there is
intrasexual competition for obtaining mates. Then, there is the need to exclude reproductive …

We develop a natural selection model for sex ratio control in a spatially variable
environment. Predictions of sex ratio alteration as a function of environmental change are …

Among vertebrates, fish show by far the greatest variability of alternative reproductive tactics
(ARTs). Usually, males attempting to monopolize access to females or fertilizations are …
