A sex-structured delayed recruitment model
Mathematical Biosciences, 1996A delay-difference model for a sex-structured population with delayed recruitment is presented. Constant-effort harvesting is introduced for examining the model's sensitivity to harvesting. Linear analyses about the steady states are performed under various parameter choices.

Structural and Functional Sex Differences in the Human Hypothalamus
Hormones and Behavior, 2001Sex differences in the brain may be the basis not only for sex differences in reproduction, gender identity (the feeling of being male or female), and sexual orientation (heterosexuality vs homosexuality), but also for the sex difference in prevalence of psychiatric and neurological diseases ( Swaab and Hofman, 1995 ).

Sex ratios in geographically structured populations
Trends in Ecology & Evolution, 1986In his book on sexual selection (1), Darwin documented evidence that the primary sex ratio (the proportion of males at conception) is about 1/2 in a wide variety of species. Otherwise, he explained, a newly conceived member of the rare sex will, on average, have more offspring than one of the common sex, since each offspring has one mother and one ...

Agonistic Structure Differentiated by Sex
2012The organization of characters into eight sets forms an implicit empirical hypothesis—the hypothesis that agonistic structure, differentiated by sex, is a fundamental shaping feature in the organization of characters in the novels. We predicted (1) that each of the eight character sets would be sharply defined by a distinct and integrated array of ...

Genome structure and the benefit of sex.
Evolution; international journal of organic evolution, 2011We examine the behavior of sexual and asexual populations in modular multipeaked fitness landscapes and show that sexuals can systematically reach different, higher fitness adaptive peaks than asexuals. Whereas asexuals must move against selection to escape local optima, sexuals reach higher fitness peaks reliably because they create specific genetic ...
