Genetic similarity and the nonrandom distribution of paternity in a genetically highly polyandrous shorebird
Article Abstract:
The potential for cryptic sperm selection in the polyandrous, lek-breeding, ruff, Philomachus pugnax is investigated. The findings have implications for the extent to which birds can adaptively optimize outbreeding, even in the absence of the behavioral ability to discriminate genetic similarity and have broad implications for sexual selection in birds, a taxon in which high levels of genetic polyandry are the norm.

Multiple nuptial flights, sperm transfer and the evolution of extreme polyandry in honeybee queens
Article Abstract:
The paternity of worker offspring of naturally mated honeybee queens was analyzed with the help of eight DNA microsatellite loci, to understand the evolution of extreme polyandry. Queens that were restricted to one nuptial flight had significantly fewer matings than queens that started oviposition after a single nuptial flight.

Male mate choice, male availabilty and egg production as limitations on polyandry in the red-necked phalarope
Article Abstract:
The factors that might affect the proportion of female red-necked phalaropes obtaining multiple mates are examined. The availability of females to produce eggs, the availability of males and male mate choice are the three factors that limit the occurrence of polyandry.
