Please cite this article in press as: Makowicz (2013), http://dx.doi.org/10.1016/j.anbehav.2 Sexual conflict can lead to individuals evolving behaviours to circumvent preferences of the opposite sex. For example, females have been shown to adjust their behaviours depending on the risk of sexual harassment. In the present study we investigated the effects of sexual harassment in sailfin mollies,...

Male sailfin mollies Poecilia latipinna were tested in five different treatments that varied in the relative frequency of heterospecific gynogens (Amazon molly Poecilia formosa) to conspecific females to determine whether social interactions among males within a population causes some males to mate with heterospecific females. Male P. latipinna inseminated a significantly higher proportion of c...

Fluctuating asymmetry is defined as random deviation from perfect bilateral symmetry in otherwise symmetrical morphological traits and originates from developmental errors during ontogeny. It is thought to reflect the inability of a genotype to buffer itself effectively against environmental perturbations, thus providing an honest phenotypic indicator of genetic quality. It has been proposed th...

The ocean surgeonfish Acanthurus bahianus, an abundant small herbivore on reefs throughout the tropical west and central Atlantic, is a significant component of Caribbean trapfishery catches. To assess effects of fishing on this species we compared its longevity, survivorship, size and abundance at localities throughout its range that have differing intensities and targets of fishing. Temperatu...
