The Common

A diversity of all-female fishes of the genus Poeciliopsis coexists with their sexual ancestor species in streams of western Mexico. All-females are hybrids that depend on the sperm of paternal species to reproduce. Rare-female advantage is one of several hypotheses that attempt to explain how the diversity of all-female biotypes is maintained within the Poeciliopsis reproductive complexes. According to this hypothesis, the uncommon all-female biotype has a mating advantage over the common ones and has been maintained by a dynamic equilibrium process. In the P. monacha reproductive complex at Arroyo de los Platanos the density of two all-female biotypes (P. 2monacha-lucida I and II) varies across pools. The objective of this study was to analyse fecundity and mating success of females from this arroyo to test the hypothesis. Female mating success was inversely correlated to their density, supporting this hypothesis.

Paratrechalea Ornata

In the spider Paratrechalea ornata, males have two gift-giving mating tactics, offering either a nutritive (prey) or a worthless (prey leftovers) silk wrapped gift to females. Both gift types confer similar mating success and duration and afford males a higher success rate than when they offer no gift. If this lack of difference in the reproductive benefits is true, we would expect all males to offer a gift but some males to offer a worthless gift even if prey are available. To test this, we allowed 18 males to court multiple females over five consecutive trials. In each trial, a male was able to produce a nutritive gift (a live housefly) or a worthless gift (mealworm exuviae). We found that, in line with our predictions, 20% of the males produced worthless gifts even when they had the opportunity to produce a nutritive one. However, rather than worthless gifts being a cheap tactic, they were related to a higher investment in silk wrapping. This latter result was replicated for worthless gifts produced in both the presence and absence of a live prey item. We propose that variation in gift-giving tactics likely evolved initially as a conditional strategy related to prey availability and male condition in P. ornata. Selection may then have favoured silk wrapping as a trait involved in female attraction, leading worthless gift-giving to invade.

Aggressive Interference

Male long-billed marsh wrens prefer to sing from the tops of cattails, but red-winged blackbirds force wrens to sing from lower perches on cattails. The response of marsh wrens to redwing aggression declines with increasing distance from redwings. Marsh wrens that are frequently exposed to redwing aggression respond less strongly to redwings at intermediate redwing–wren distances than wrens that rarely encounter redwings. This is probably because marsh wrens habituate to redwings and learn to respond only to those situations when redwings present an immediate threat.Marsh wrens responded strongly to redwings but little or not at all to nine other species that approached them. This species-specific response is most likely associated with redwing–wren aggressive interference. It is proposed that by suppressing marsh wren singing activities redwings might depress the mating success of male marsh wrens that defend territories near redwing breeding areas.
