Historical and experimental learned predator recognition in free-living New Zealand robins

Article Abstract:

New Zealand birds do not have a genetically evolved set of response options to mammals, as they were introduced to mammals only in the 18th century. The responses of naive and experienced robins in New Zealand were observed and compared. The experienced mainland robins reacted strongly to the introduced mammal, while the naive island robins had a weak response. The response learning took place after just one exposure. Predator training is an important addition to any endangered species reintroduction program.

Female weight predicts the timing of forced copulation attempts in stitchbirds, Notiomystis cincta

Article Abstract:

A correlational approach is used to examine which behavioral cues are closely linked with the fertile status of the female stitchbirds, as well as which cues account for patterns of extrapair male behavior. Increasing female weight appears to be the primary fertility indicator in this species and it is likely that males evaluate this through changes in her flight behavior.

Physiological dependence on copulation in parthenogenetic females can reduce the cost of sex

Article Abstract:

Parthenogenetic dependence on copulatory stimuli in parthenogenetic females is discussed. This mechanism provides a short-term advantage to sexual reproduction and thus, facilitates the maintenance of sex in a mixed population following the invasion of an asexual competitor.
