“…In Townsend's voles (M. townsendii ), inbreeding avoidance influenced the dispersal of males but not females (Lambin 1994). Prairie voles (M. pennsylvanicus) introduced to experimental plots with siblings were more likely to disperse than were those released with nonrelatives (Bollinger et al 1993).…”

Abstract. We investigated factors influencing natal dispersal in 231 female yearling yellow-bellied marmots (Marmota flaviventris) using comprehensive analysis of 10 years (1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992)(1993) of radiotelemetry and 37 years of capture-mark-recapture data. Only individuals whose dispersal status was verified, primarily by radiotelemetry, were considered. Univariate analyses revealed that six of the 24 variables we studied significantly influenced dispersal: dispersal was less likely when the mother was present, amicable behavior with the mother and play behavior were more frequent, and spatial overlap was greater with the mother, with matriline females, and with other yearling females. Using both univariate and multivariate analyses, we tested several hypotheses proposed as proximate causes of dispersal. We rejected inbreeding avoidance, population density, body size, social intolerance, and kin competition as factors influencing dispersal. Instead, our results indicate that kin cooperation, expressed via cohesive behaviors and with a focus on the mother, influenced dispersal by promoting philopatry. Kin cooperation may be an underappreciated factor influencing dispersal in both social and nonsocial species.

“…In many bird and mammal species, dispersal of individuals away from their natal groups or sites, especially those of just 1 sex, separates close relatives and thus prevents inbreeding (Hoogland 1992, Bollinger et al 1993, Pusey & Wolf 1996, Daniels & Walters 2000. On the other hand, species with low dispersal ability often inbreed routinely (Riechert & Roeloffs 1993, Clarke & Faulkes 1999, Bilde et al 2005.…”

“…Indeed, the evidence for kin-competition-based dispersal is starting to accumulate. Kin-mediated dispersal has been suggested to exist in gray jays (19), mice (20), and red foxes (21) and has been demonstrated in voles (22), insects (23), and lizards (24). Kinbased habitat choice also has been demonstrated in a crow (25) and in a lizard (15).…”

Colonization is the crucial process underlying range expansions, biological invasions, and metapopulation dynamics. Which individuals leave their natal population to colonize empty habitats is a crucial question and is presently unresolved. Dispersal is the first step in colonization. However, not all dispersing individuals are necessarily good colonizers. Indeed, in some species, the phenotype of dispersers differs depending on the selective pressures that induce dispersal. In particular, kin-based interactions, a factor driving social evolution, should induce different social response profiles in nondispersing and dispersing individuals. Kin competition (defined here as between the mother and offspring) has been proven to produce dispersers with a particular phenotype that may enhance their colonizing ability. By using the common lizard (Lacerta vivipara), we conducted a multipopulation experiment to study the effect of kin competition on dispersal and colonization success. We manipulated mother-offspring interactions, which are the most important component of kin competition in the studied species, at the family and population levels and measured the consequences on colonization success. We demonstrate that mother-offspring competition at the population level significantly influences colonization success. Increased competition at the population level enhanced the colonization rate of the largest juveniles as well as the growth and survival of the colonizers. Based on these results, we calculated that kin-induced colonization halves the extinction probability of a newly initiated population. Because interactions between relatives are likely to affect the ability of a species to track habitat modifications, kin-based dispersal should be considered in the study of invasion dynamics and metapopulation functioning.common lizard ͉ dispersal ͉ kin interactions
