Effects of male‐biased dispersal on inbreeding avoidance were investigated in a semi‐natural population of Myodes (formerly Clethrionomys) rufocanus using a large outdoor enclosure (3 ha). Parentage of 918 voles weaned from 215 litters and relatedness of mates were analysed using microsatellite loci, and dispersal distances were obtained from mark–recapture live‐trapping data. Natal and breeding male‐biased dispersal was observed. There remained, however, chances that incestuous mating could… Expand
Male-biased dispersal causes intersexual differences in the subpopulation structure of the gray-sided vole.
TLDR
The findings indicate that the extent of subpopulations within which individuals interact differs between sexes, and the observed genetic structure in males could be generated by modifying the observed haplotype distribution of females by adding the effects of local male dispersal. Expand
Consequences of natal philopatry for reproductive success and mate choice in an Alpine rodent
TLDR
The results show how quantification of SGS within populations can provide insights into individual dispersal behavior and its fitness consequences, and into the ways in which social and genetic structure interacts to shape the evolution of free-living populations. Expand
Estimation of multiple male mating frequency using paternity skew: An example from a grey‐sided vole (Myodes rufocanus) population
TLDR
A method to estimate MMM frequency using an individual‐based model with three variables (MP frequency, LS and FPS), which incorporated observed paternity skew data to infer a possible range of FPS that cannot be measured in free‐living populations and tested the validity of the method using data set from a grey‐sided vole population and from hypothetical populations.

Patterns and processes of dispersal behaviour in arvicoline rodents
TLDR
It is suggested that costs and benefits experienced during transience and settlement are prime determinants of condition dependence, except for a widespread association between an exploration/activity syndrome and natal dispersal. Expand
Sexual maturation and age-related dynamics of corticosterone in Clethrionomys rutilus and Cl. rufocanus voles (Rodentia, Cricetidae) under experimental conditions
TLDR
Differences in the mechanisms regulating reproduction between the northern red- backed vole and large-toothed red-backed vole have been revealed under vivarium conditions and no definite relationship between sexual maturation and the level of adrenocortical activity has been revealed in Cl. rutilus. Expand
Role of individual dispersal in genetic resilience in fluctuating populations of the gray‐sided vole Myodes rufocanus
TLDR
It is suggested that, in gray‐sided vole populations, genetic diversity varies with density largely at the local scale; in contrast, genetic variation in a metapopulation is well‐preserved at the regional scale due to the density‐dependent dispersal behaviors of individuals. Expand
Preference for Outbreeding in Inbred Littledale’s Whistling Rats Parotomys littledalei
TLDR
It is proposed that the choice to inbreed or outbreed in female whistling rats depends on their inbreeding status and the genetic relatedness of available mates, with outbreeding more likely to occur unless unrelated mates are not available. Expand
Cytochrome b gene (cytb) sequence diversity in a Microtus oeconomus population from Bialowieza Primeval Forest
TLDR
A more complete haplotype network for root voles in Europe was constructed by combining the newly identified haplotypes with the 45 previously described haplotypes, and two of the haplotypes detected in this study occupy key positions in this network: PLB5, as the closest link to the North European group, and PLB8, as an ancestor to many other Central European haplotypes.

Serial sampling bridges a gap between ecological and genetical definitions of immigrant: an empirical test in a grey-sided vole population
The assignment test is believed to have the potential to estimate the contemporary rate of immigration and is considered as an alternative to ecological methods (e.g., mark-recapture and radio/GPSExpand
Kinship, Social Structure, and the Ecological Bases for Sociality in Torch-Tail Spiny Rats, Trinomys yonenagae (Rodentia: Echimyidae): Evidence from Field and Molecular Data
TLDR
The torch-tail spiny rat (Trinomys yonenagae) is a South American hystricognath rodent endemic to semiarid sand dunes in northeastern Brazil and field studies with molecular genetic analyses were combined to characterize the social organization and kin structure and identify the primary ecological factors influencing sociality in this species.

Effect of Local Density of Males on the Occurrence of Multimale Mating in Gray-sided Voles (Myodes rufocanus)
TLDR
The results suggest that multimale mating occurs because dominant males cannot deter subordinates from access to their mates when local density of males is high. Expand

TLDR
It is concluded that inbreeding avoidance influenced natal philopatry in males and that competition for resources influenced nata philop atry in females. Expand

TLDR
The estimation of frequency of multiple paternity indicated that multiple paternity was rare in this population, and strong evidence for mate selection in these six male traits could not be found, although some differences in the means of flank gland size and seminal vesicle weight between 10 successful males and the population were observed.

It is demonstrated that inbreeding depression significantly elevated extinction risk in red-cockaded woodpecker populations, and lowering interterritorial distances can be viewed as a valuable conservation tool. Expand
No Evidence for Inbreeding Avoidance in a Natural Population of Song Sparrows (Melospiza melodia)
TLDR
A simple model is presented to suggest that variation in inbreeding avoidance behaviors in birds may arise from differences in survival rates: in species with low survival rates, the costs of forfeiting matings to avoid inbreeding may exceed the cost of inbreeding. Expand
Inbreeding depression along a life‐history continuum in the great tit
TLDR
Analysis of the effects of close inbreeding, based on observations of mating between relatives, in a large, free‐living noninsular great tit (Parus major) population monitored over 41’years, shows that inbreeding depression acts independently at each life‐history stage in this population, and suggests that estimates of the fitness costs of inbreeding must focus on the entire life cycle.

Asymmetrical incest avoidance in the choice of social and genetic mates
TLDR
A model of asymmetrical incest avoidance is supported, which predicts differences in the likelihood of incestuous matings as a function of sex, age and relationship, even when coefficients of inbreeding are identical. Expand

The impact of habitat alteration (deforestation) on inbreeding in the rock‐dwelling Australian lizard Egernia cunninghami was reported on and outbreeding was maintained in the face of increased accumulation of relatives. Expand

It appears that inbreeding avoidance can influence dispersal movements of the meadow vole and may be partially responsible for patterns of male—biased dispersal in at least some mammals. Expand
No evidence for inbreeding avoidance in a great reed warbler population
TLDR
It is suggested that dispersal is a sufficient inbreeding avoidance mechanism in most situations, although the lack of kin discriminative mate choice has negative consequences for some females, because they end up mating with closely related males that lowers their fitness. Expand
