Females nested close to their parents and sisters, but settling of males conformed to a random pattern. The apparent preference for breeding close to kin in females could be a by-product of extreme philopatry to the natal nest site. However, sisters also nested close to each other when settling on a different island than the one where their parents bred, pointing at a genuine preference for breeding close to kin. Females only nested close to sisters born in the same year (i.e., sisters that they had been in close contact with). This suggests that the clustering of female kin in barnacle geese does not result from phenotype matching. We did not detect any direct benefits of settling close to birth site or kin, but the analyses lacked power to detect small benefits of proximity to kin given the many other factors that may influence breeding success. Colonially breeding birds share characteristics that are generally believed to promote the evolution of cooperation, yet kin clustering and kin selection have been little studied in this group. Future research should be directed to studying the possible roles of kin clustering and kin selection in the evolution of coloniality.</p>

Also, it allows a more adequate and rapid response to rapidly changing environments. When individuals break with their migratory traditions, new population structures can emerge that may affect gene flow. Recently, the migratory traditions of the Barnacle Goose Branta leucopsis changed, and new populations differing in migratory distance emerged. Here, we investigate the population genetic structure of the Barnacle Goose to evaluate the consequences of altered migratory traditions. We used a set of 358 single nucleotide polymorphism (SNP) markers to genotype 418 individuals from breeding populations in Greenland, Spitsbergen, Russia, Sweden and the Netherlands, the latter two being newly emerged populations. We used discriminant analysis of principal components, FST, linkage disequilibrium and a comparison of geneflow models using migrate-n to show that there is significant population structure, but that relatively many pairs of SNPs are in linkage disequilibrium, suggesting recent admixture between these populations. Despite the assumed traditions of migration within populations, we also show that genetic exchange occurs between all populations. The newly established nonmigratory population in the Netherlands is characterized by high emigration into other populations, which suggests more exploratory behaviour, possibly as a result of shortened parental care. These results suggest that migratory traditions in populations are subject to change in geese and that such changes have population genetic consequences. We argue that the emergence of nonmigration probably resulted from developmental plasticity.</p>
