Why are females so choosy when it comes to mating? This question has puzzled and
marveled evolutionary and behavioral ecologists for decades. In mating systems in which …

Publisher Summary The sounds produced by orthopteran insects are very diverse. They are
widely studied for the insight they give into acoustic behaviour and the biophysical aspects …

Accurate phylogenies are crucial for understanding evolutionary processes, especially
species diversification. It is commonly assumed that “good” species are sufficiently isolated …

The trade–up hypothesis outlines a behavioural strategy that females could use to maximize
the genetic benefits to their offspring. The hypothesis proposes that females should be more …

Phosphorus has been identified as an important determinant of nutrition-related biological
variation. The macronutrients protein (P) and carbohydrates (C), both alone and …

Much of the theory of sexual selection assumes that females do not generally experience
difficulties getting their eggs fertilized, yet sperm limitation is occasionally documented. How …

Females are generally assumed to prefer larger, more dominant males. However, a growing
number of studies that control for male-male competition have shown no correlation …

1. Immune defence has recently been viewed as a life-history trait that shows trade-offs with
other life-history traits. However, studies exploring correlations between different …

In choosing a breeding partner, females in many animal species select between available
males on the basis of several signalling traits. Some theoretical models of signalling …

It is becoming increasingly clear that the evolutionary interests of the sexes are often in
conflict when it comes to mating. Sexual encounters involving nuptial gifts, however, have …
