Populations of Peromyscus polionotus, the oldfield mouse, are organized into family groups which are characterized by a high degree of monogamy. There is no evidence that females of this species ever mate with more than one male for each litter. Females that are collected in the field with males have the same mate for consecutive litters (the frequency of mate switching for these females does not differ significantly from zero). In addition, the male that is collected with the female is usually… 

Extra pair copulation in the Eurasian beaver (Castor fiber)

Based on the genetic data it appears that the Eurasian beaver is a strict genetically monogamous species, in concordance with the observational data.


Using 3 different criteria allowed a greater number of male paternity assignments to be inferred than would have been possible when using software program CERVUS alone, and increased confidence in these results.

Mating tactics and paternity in a socially monogamous canid, the bat-eared fox (Otocyon megalotis)

It is suggested that the relatively low level of EPP in the bat-eared fox may be influenced partly by diet and foraging behavior, which makes it easy for males to maintain close proximity to partners and costly for either sex to roam in search of extrapair mates.

Studies of sperm competition in two species of muroid rodents

Results suggest that effects of mating order are highly species-specific and must be evaluated for each species before speculations are made regarding the effects of multiple matings, and females of the brown-recessive genotype mated with one male are only slightly less likely to become pregnant than wild-type females.

Mating System and Reproductive Success in a Free-Living Population of the Bank Vole, Clethrionomys Glareolus

The mating system in a free-living population of the bank vole (Clethrionomys glareolus) was examined by mark-recapture and electrophoretic techniques and Reproductively successful males were not distinguishable from all available males by age, mass, or body size.


The results suggest that female prairie voles that are not mate-guarded will mate with multiple partners, and social preference was a good predictor of sexual preference.

Mating system of the meadow vole, Microtus pennsylvanicus

It is argued that the presence of promiscuity, rather than polygyny, in M. pennsylvanicus is the result of two factors: first, overwintered breeding males are similar in age and size, resulting in small variation in competitive ability among males, and the habitat structure of the meadow vole makes it difficult for a male to detect other males nearby.

Mating system and reproductive success in a spring population of the red-backed vole, Clethrionomys rufocanus bedfordiae

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.

Mechanisms of sexual fidelity in the monogamous California mouse, Peromyscus californicus

Results indicate that monogamy in P. californicus is maintained by a strong attraction and preference of pairmates for each other and by self-restraint from mating with others.

This paper is a report of direct evidence of frequent multiple male parentage within single litters in natural populations of deer mice (Peromyscus maniculatus), suggesting that in these populations the social units must be large enough to include two, or probably more, breeding males.

Detailed analyses of multiple captures of Reithrodontomys megalotis using live trapping indicate that individuals of this species frequently travel in pairs. Female-male combinations were the most

Maximum-likelihood estimation of the proportion of nonpaternity.

THE USE OF GENETIC DATA to estimate the proportion of nonpaternity or extramarital illegitimacy has been discussed in recent writings (Li, 1961, p. 35; NIacCluer and Schull, 1963). We will use the

In diagnosis of paternity by means of polymorphic markers, the proportion of men excluded on the basis of the phenotypes of the mother and child is the best index for controlling information. Its
