Genetic information is used extensively to reconstruct the evolutionary and demographic
history of organisms. Recently, it has been suggested that genetic information from some …

Background Female sex pheromones attracting mating partners over long distances are a
major determinant of reproductive isolation and speciation in Lepidoptera. Males can also …

Although dispersal distance plays a major role in determining whether organisms will reach
new habitats, empirical data on the environmental factors that affect dispersal distance are …

… Competition between the two groups of 20 perfumed males for matings with 20 3- to 5-day-old
virgin stock females was performed in a 3 × 3 × 3 m net-covered, wood-framed cage …

The co-evolution between hosts and parasites has long been recognized as a fundamental
driver of macro-evolutionary patterns of diversification. The effect of co-differentiation on …

Selection can facilitate diversification by inducing character displacement in mate choice
traits that reduce the probability of maladaptive mating between lineages. Although …

Inbreeding depression results from mating among genetically related individuals and impairs
reproductive success. The decrease in male mating success is usually attributed to an …

We review experimental and theoretical evidence that learning in insects and spiders affects
the expression of mate preferences and of sexual signals, the evolution of both traits, and …

Numerous cases of evolutionary trait loss and regain have been reported over the years. Here,
we argue that such reverse evolution can also become apparent when trait expression is …

Chemical communication in insects' sexual interactions is well-known to involve olfaction of
volatile compounds called sex pheromones. In theory, sexual chemical communication may …
