“…The results from this study contrast with those from Friesen et al (1996a) at the Norway colony in the degree of structuring. The observed differences may be partly explained by effects of sampling, the markers employed, or the age and size of the colonies.…”

“…Although both Hornøya and Coats Island colonies may have been undergoing population growth at the time of sampling, the Norway colony has remained overall small and was recovering from a population reduction, while the Canadian colony has remained large, may be growing at a faster rate and may not yet be in genetic equilibrium. Assuming a generation time of 8.8 years (Southern et al 1965, Friesen et al 1996a), less than 285 generations have elapsed since founding. The age of establishment of the ledges at these colonies is not well documented, but at least some ledges within Coats Island may have been established too recently to have reached genetic equilibrium (e.g.…”

Many seabirds exhibit high natal philopatry despite their extreme dispersal ability and delayed reproduction, and some exhibit phenotypic clustering in colonies and fostering or adoption of neighbouring chicks. Previous investigations of kinship in a small thick-billed murre colony Uria lomvia (Alcidae) in Norway revealed high relatedness among breeders on cliff ledges. To investigate the presence of kin groups and within-colony genetic sub-structuring elsewhere, we investigated kinship within a larger murre colony on Coats Island, Nunavut, Canada. Morphological (five characters) and genetic data (five microsatellite loci and a fragment of the mitochondrial cytochrome b gene) were analysed. Strong morphological differentiation was found among ledges. Genetic structuring was overall weak but significant at the coarse scale for males among ledges and on the east vs. the west side of the colony. Global spatial autocorrelation analyses did not detect consistent, widespread spatial patterns, although local 2D analyses provided some evidence of a tendency for larger neighbourhood sizes for females and a broad range of small to large neighbourhoods for males. Average withinledge relatedness was low overall, but ranged widely from slightly unrelated to greater than the level of cousins in both sexes. Kin-level relationships occurred on ledges more frequently for same-sex groups than expected by chance, suggesting that recruiting breeders (especially females) avoid or are unable to settle directly adjacent to relatives particularly of the opposite sex. Behavioural studies of natal dispersal of murres at Coats I. indicating that both sexes are highly philopatric, but that up to one-fifth of females may disperse, are concordant with this study. Overall, structuring was weaker than in Norway, and may be explained in part by genetic marker and sampling artifacts, and by the lack of genetic equilibrium suspected in the much larger Canadian Arctic colony. Natal philopatry may be an important factor driving the diversification of seabirds and kin groups in other colonies and species and may be more widespread than is currently acknowledged.

“…At Columbretes, the site with the lowest area of breeding habitat and the lowest mean breeding success and population densities, fidelity of resident breeders was much lower than in the other sites, confirming previous studies showing that habitat quality influences transience and fidelity to the patch (Serrano et al 2001, Hoover 2003, Cam et al 2004. At the remaining study sites, fidelity was much higher or remained high for most of the study years, probably because individuals with breeding experience in a given site are generally reluctant to disperse due to the benefits of a better knowledge of the local environment (Friesen et al 1996, Forero et al 1999. The association between fidelity to the breeding Table 2).…”

When to stay, when to disperse and where to go: survival and dispersal patterns in a spatially structured seabird population

Dispersal is a key process for the population dynamics of spatially structured populations (at local and metapopulation levels), so the understanding of the mechanisms underlying the movement of individuals in space and time is important for evolutionary and ecological studies. Here we analyzed, for the first time, a long‐term (1992–2009) multi‐site capture– recapture database collected at four local populations of a long‐lived seabird, the Audouin’s gull Larus audouinii, covering 90% of its total world population. Those local populations show different ecological and demographic features that allow us to assess the influence of several key factors involved in breeding dispersal patterns at large spatio‐temporal scales. A recently developed analytical tool in mark–recapture modelling, the multi‐event approach, allowed us to obtain separate departure and settlement probabilities and test different biological hypotheses for each step of the dispersal process. Our results revealed that site fidelity was the most common strategy among breeders, and dispersal was only high from the site with the lowest population size and habitat quality. However, departures from the two largest local populations increased over the study period in response to severe ecological perturbations. Dispersers chose different settlement patches depending on their site of origin, with settlement choices determined by the population size of the destination colony rather than by the local reproductive performance, foraging area (a proxy of food availability) or distance to the destination site. Our results indicate that a breeding site is not abandoned by breeders unless a series of cumulative perturbations occur; once dispersing, settlement is directed towards densely populated sites, with dispersers using population size to rapidly assess the quality of the breeding patch.

“…Fine-scale population genetic structure has been measured for a larger number of species that are not regarded as cooperative breeders and it is notable that many of these exhibit significant kin structure, e.g. pilot whales Globicephala melas (Amos et al 1991); Brunnich's guillemots Uria lomvia (Friesen et al 1996); tilapia Sarotherodon melanotheron (Pouyaud et al 1999); manakins Manacus manacus (Shorey et al 2000); black grouse Tetrao tetrix (Hö glund et al 1999); Soay sheep Ovis aries (Coltman et al 2003); tuco-tuco Ctenomys talarum (Cutrera et al 2005); blue tits Cyanistes caeruleus (Foerster et al 2006); dolphins Stenella coeruleoalba (Gaspari et al 2007); woodrats Neotoma fuscipes (McEachern et al 2007); red grouse Lagopus lagopus (Piertney et al 2008); Galapagos sea lion Zalophus wollebaeki (Wolf & Trillmich 2008); vinous-throated parrotbills Paradoxornis webbianus (Lee et al 2009); beaver Castor canadensis (Crawford et al 2009); and woodchuck Marmota monax (Maher 2009). Thus, even if this is not a representative sample, it is clear that fine-scale genetic structure is a widespread phenomenon in populations of non-cooperative species as well as cooperative ones.…”

Cryptic Kin Selection: Kin Structure in Vertebrate Populations and Opportunities for Kin‐Directed Cooperation

2010

Animal societies of varying complexity have been the favoured testing ground for inclusive fitness theory, and there is now abundant evidence that kin selection has played a critical role in the evolution of cooperative behaviour. One of the key theoretical and empirical findings underlying this conclusion is that cooperative systems have a degree of kin structure, often the product of delayed dispersal, that facilitates interactions with relatives. However, recent population genetic studies have revealed that many non‐cooperative animals also have kin‐structured populations, providing more cryptic opportunities for kin selection to operate. In this article, I first review the evidence that kin structure is widespread among non‐cooperative vertebrates, and then consider the various contexts in which kin selection may occur in such taxa, including: leks, brood parasitism, crèches, breeding associations, territoriality and population dynamics, foraging and predator deterrence. I describe the evidence that kin‐selected benefits arise from interacting with kin in each of these contexts, notwithstanding the potential costs of kin competition and inbreeding. I conclude that as the tools required to determine population genetic structure are readily available, measurement of kin structure and the potential for kin selection on a routine basis is likely to reveal that this process has been an important driver of evolutionary adaptation in many non‐cooperative as well as cooperative species.
