Host-parasite relatedness has been suggested to promote the evolution of conspecific brood parasitism, an alternative reproductive tactic pursued by females in several animal taxa. An essential prerequisite for relatedness to promote brood parasitism is accurate kin recognition, including the recognition of related hosts by parasites. I performed a field experiment to address the accuracy of host recognition by parasites in the common goldeneye (Bucephala clangula), a cavity-nesting duck. I studied whether parasites discriminate between experimental nests that did not have a host (i.e., new nest boxes that contained chicken eggs dyed to mimic the colour of common goldeneye eggs) and real nests that did have a host (i.e., active nests that progressed to incubation). Parasitic egg laying in the experimental nests was not constrained by the lack of contemporarily available nests that had a host; it was also not constrained by the lack of suitable and empty nest sites. There was no difference in the start of parasitic laying between the experimental and real nests. The experimental nests and real nests were equally parasitized. The findings suggest that host recognition by parasites is not sophisticated in the common goldeneye, questioning the possible function of accurate kin recognition in brood parasitism in this species.

Necessary And Sufficient

Using a series of chimeric and truncated N-acetylglucosaminyltransferase I (NAGT I) molecules we have shown that part of the lumenal stalk region is both necessary and sufficient for kin recognition of mannosidase II and retention in the Golgi stack. The membrane-spanning domain was not required for retention, but replacing part or all of this domain with leucine residues did have a dramatic effect on Golgi morphology. In stable cell lines, stacked cisternae were replaced by tubulo-vesicular clusters containing the mutated NAGT I. The loss of stacked cisternae was proportional to the number of leucines used to replace the membrane-spanning domain.

Abstract While the importance of kin discrimination, that is, kin recognition and subsequent differential treatment of kin and nonkin, is well established for kin-directed cooperation or altruism, the role of kin discrimination in the context of kin competition and kin avoidance is largely unexplored. Theory predicts that individuals avoiding competition with kin should be favored by natural selection due to indirect fitness benefits. Using an experimental approach, we investigated whether the presence of same-sex kin affects avoidance and explorative behavior in subadult Pelvicachromis taeniatus, a West African cichlid fish with strong intrasexual competition in both sexes. Pelvicachromis taeniatus is capable of recognizing kin using phenotype matching and shows kin discrimination in diverse contexts. When exposed to a same-sex conspecific, both males and females tended to interact less with the related opponent. Moreover, individuals explored a novel environment faster after exposure to kin than to nonkin. This effect was more pronounced in females. Individuals avoiding the proximity of same-sex relatives may reduce kin competition over resources such as mating partners or food.
