“…Most conceptions occur in a relatively short period of time (2-4 weeks in temperate populations- Marchinton and Hirth 1984). The overall spatial dispersion of females within populations combined with temporal synchro- ny of estrus would limit the number of estrous females an individual male can locate and breed, allowing more males access to mating opportunities (e.g., Say et al 2001). Finally, there is evidence for female promiscuity in white-tailed deer (DeYoung et al 2002(DeYoung et al , 2006Sorin 2004), which may further enhance chances of successful mating by males of all age classes (e.g., Pemberton et al 1999).…”

We used genetic-based paternity assignments from 3 diverse populations of white-tailed deer (Odocoileus virginianus) to evaluate the long-held assumption that male reproductive success in this species is highly skewed toward a small number of mature, dominant individuals. The study populations represented a range of adult sex ratios and male age structures. Male reproductive success was distributed among a large number of males in all populations, with no evidence for highly skewed access to mating for any individual male. Surprisingly, physically immature males (1.5 and 2.5 years of age) collectively fathered 30-33% of offspring in all populations, even where mature males were present. Ecological and behavioral variables appear to constrain the ability of individual males to monopolize access to females, resulting in a wider distribution of reproductive success than expected based on previous ecological and behavioral studies of white-tailed deer. Qualitative differences in the distribution of male reproductive success among study sites suggested that demographic attributes such as adult sex ratio and male age structure might influence the degree of competition for mates. Further study incorporating known-age cohorts or integrating movements and behavior is necessary for understanding the effects of population demographics as well as the physical and behavioral attributes that confer reproductive success in diverse populations of white-tailed deer.

“…Finally, the marked breeding synchrony that necessary results from these time constraints presumably limits the number of partners that a male may fertilize (Say et al 2001). As a result, choosing a sister would jeopardize other mating opportunities, thereby suppressing the potential benefits of inbreeding.…”

Inbreeding in the Greater White-Toothed Shrew, Crocidura Russula

et al. 2003

Abstract. We combined mark-and-recapture studies with genetic techniques of parentage assignment to evaluate the interactions between mating, dispersal, and inbreeding, in a free-ranging population of Crocidura russula. We found a pattern of limited and female-biased dispersal, followed by random mating within individual neighborhoods. This results in significant inbreeding at the population level: mating among relatives occurs more often than random, and F IT analyses reveal significant deficits in heterozygotes. However, related mating partners were not less fecund, and inbred offspring had no lower lifetime reproductive output. Power analyses show these negative results to be quite robust. Absence of phenotypic evidence of inbreeding depression might result from a history of purging: local populations are small and undergo disequilibrium gene dynamics. Dispersal is likely caused by local saturation and (re)colonization of empty breeding sites, rather than inbreeding avoidance. Because natural populations are finite in size, mating sometimes occurs among relatives, even when partners meet at random. Offspring born from such matings are said to be inbred, and they often display phenotypic abnormalities resulting in a loss of fitness through lower viability or fertility. This inbreeding depression has been repeatedly documented in a number of natural populations, including invertebrates

Sexual selection in wild baboons: from mating opportunities to paternity success

2006

In mammals, high dominance rank among males is often associated with mating success. However, mating opportunities do not automatically translate into offspring production; observed mating success may be discordant with offspring production, for three reasons.(1) Observed mating may be nonrepresentative of actual mating if some mating is surreptitious (decreasing the chance that it will be observed), (2) mating may be nonrandom if some males allocate more mating effort to females with high fertility (i.e. if some males differentially invest in higher fertility mating) and (3) conception success may be nonrandom if sperm competition or sperm selection play a role in conception. We performed a genetic analysis of paternity in the well-studied savannah baboon, Papio cynocephalus, population in the Amboseli basin, eastern Africa, in order to measure the concordance between observed mating success and actual offspring production. We found that observed mating success was generally a good predictor of paternity success, that high-ranking males had higher paternity success than lower-ranking males, and that male density and male rank stability contributed to variance in male paternity success. We found little evidence for successful surreptitious mating (although subadult males did occasionally produce offspring, apparently using this strategy), and no clear evidence for differential sperm success or sperm depletion (although we could not rule them out). However, we found clear evidence that high-ranking males showed mate choice, concentrating their mating efforts on females experiencing conceptive rather than nonconceptive cycles.
