Mating system and sex allocation in the gregarious parasitoid Cotesia glomerata

Article Abstract:

A study was conducted, using the parasitic wasp Cotesia glomerata, to investigate the influences of natal dispersal behavior in the mating system. The result confirms that mating system plays a role in the evolution of natal dispersal behavior in Cotesia glomerata, and suggests that the sex allocation strategy of this species is based on both partial local mate competition in males and inbreeding avoidance in females.

Polymorphic signals of harassed female odonates and the males that learn them support a novel frequency-dependent model

Article Abstract:

The learned mate recognition (LMR) hypothesis assumes that sexual harassment favors signal variation among females. The distribution of color polymorphisms in odonata predicts general conditions favoring variation in sexual signals, and provides a novel frequency-dependent model for speciation via sexual signalling.

Mating behavior in the endangered Sonoran topminnow: Speciation in action

Article Abstract:

The mating behavior and preferences in the two species of the endangered Sonoran topminnow, Poeciliopsis occidetalis and Poeciliopsis sonoriensis, is studied. Results show difference in mating behavior of the two species from no-choice mating observations.
