No evidence for inbreeding avoidance through active mate choice in red-billed gulls

Inbreeding avoidance through mate choice

Evolution of Inbreeding Avoidance and Inbreeding Preference through Mate Choice among Interacting Relatives.

While extensive population genetic theory predicts conditions favoring evolution of self-fertilization versus outcrossing, there is no analogous theory that predicts conditions favoring evolution of inbreeding avoidance or inbreeding preference enacted through mate choice given obligate biparental reproduction. Multiple interacting processes complicate the dynamics of alleles underlying such in...

No evidence for postcopulatory inbreeding avoidance in Drosophila melanogaster.

Selection to avoid inbreeding is predicted to vary across species due to differences in population structure and reproductive biology. Over the past decade, there have been numerous investigations of postcopulatory inbreeding avoidance, a phenomenon that first requires discrimination of mate (or sperm) relatedness and then requires mechanisms of male ejaculate tailoring and/or cryptic female ch...

Mate choice for optimal (k)inbreeding.

Mating between related individuals results in inbreeding depression, and this has been thought to select against incestuous matings. However, theory predicts that inbreeding can also be adaptive if it increases the representation of genes identical by descent in future generations. Here, I recapitulate the theory of inclusive fitness benefits of incest, and extend the existing theory by derivin...

Fredensborg et al.—Gut helminths from red-billed gulls

Eight species of gastrointestinal helminths were obtained from the red-billed gull (Larus novaehollandiae scopulinus Forster, 1844) from Otago Peninsula, of which six were new host records. One of these, Maritrema novaezelandensis (Trematoda), was a species new to science which is being described elsewhere; the other five were Curtuteria australis (Trematoda), Echinoparyphium recurvatum (Tremat...
