Socially monogamous male birds are predicted to maximise their reproductive success by pursuing extra-pair copulations (EPCs) while engaging in anti-cuckoldry behaviour such as mate guarding. In the stitchbird, Notiomystis cincta, high levels of forced EPCs and a high proportion of nestlings resulting from extrapair fertilisations lead to the prediction that males of this species should exhibit...

The human fungal pathogen Candida albicans can reversibly switch between two cell types named "white" and "opaque," each of which is stable through many cell divisions. These two cell types differ in their ability to mate, their metabolic preferences and their interactions with the mammalian innate immune system. A highly interconnected network of eight transcriptional regulators has been shown...

In cooperatively breeding birds multiple maternity and paternity of broods is not uncommon, reproduction often being shared among group members as well as with extragroup members. We investigated the extent of extrapair paternity and intraspecific brood parasitism in a population of cooperatively breeding long-tailed tits. Our aim was to determine the frequency and cause of mixed parentage and ...

the internet along with many advantages has some disadvantages, and the lack of a complete understanding of cyberspace can cause damage in terms of mate selection method. this article attempts to address some of the disadvantages and threats that virtual spaces create in mate selection method and tries to introduce some strategies to prevent and reduce these emerging injuries. this study was co...

In sequentially polyandrous birds, a female’s second mate faces a substantial risk of cuckoldry due to rapid mate switching and stored sperm. Secondary males are potentially available to females because males arrive asynchronously and/or are recycled into the breeding pool following nest predation. In a study of red-necked phalaropes, Phalaropus lobatus, a sex-role reversed shorebird, we tested...
