Why do females mate multiply? A review of the genetic benefits

Article Abstract:

The potential benefits gained by females from mating more than once during a single reproductive cycle are examined. Multiple mating can enhance offspring fitness by increasing numbers of potential sires that compete. It is concluded that post-copulatory mechanism are a reliable way of selecting a genetically compatible mate, compared to pre-copulatory mate choice.

Potential mechanisms of avian sex manipulation

Article Abstract:

The potential mechanisms that the birds use to manipulate the sex of their progeny and the role played by maternal hormones are explained. The occurrence of sex manipulation and the potential factors promoting sex manipulation are discussed.

Seeing in the dark: molecular approaches to the study of bat populations

Article Abstract:

Research into the behaviour of bat populations using molecular genetics is presented. Molecular studies of migratory and sedentary bat species are reviewed, offering insights into bats' mating behaviour, social organisation and ecology.
