“…Interestingly, the genetic data revealed that two subadults (one male and one female) living in two different family groups were not the offspring of the breeders in those groups. Radespiel et al (2002) investigated the mating system of a captive population of seven groups of grey mouse lemurs (Microcebus murinus) using 13 microsatellite marker loci and found no relationship between male dominance rank and reproductive success within groups. Finally, used seven microsatellite markers to determine paternity in multimale groups of red-fronted lemurs (Eulemur fulvus rufus) and found that socially dominant, central males fathered 9 of the 12 offspring born into four social groups over a 2-year period.…”

In the past several decades, the development of novel molecular techniques and the advent of noninvasive DNA sampling, coupled with the ease and speed with which molecular analyses can now be performed, have made it possible for primatologists to directly examine the fitness effects of individual behavior and to explore how variation in behavior and social systems influences primate population genetic structure. This review describes the theoretical connections between individual behavior and primate social systems on the one hand and population genetic structure on the other, discusses the kinds of molecular markers typically employed in genetic studies of primates, and summarizes what primatologists have learned from molecular studies over the past few decades about dispersal patterns, mating systems, reproductive strategies, and the influence of kinship on social behavior. Several important conclusions can be drawn from this overview. First, genetic data confirm that, in many species, male dominance rank and fitness are positively related, at least over the short term, though this relationship need not simply be a reflection of malemale contest competition over mates. More importantly, genetic research reveals the significance of female choice in determining male reproductive success, and documents the efficacy of alternative mating tactics among males. Second, genetic data suggest that the presumed importance of kinship in structuring primate social relationships needs to be evaluated further, at least for some taxa such as chimpanzees in which demographic factors may be more important than relatedness. I conclude this paper by offering several suggestions of additional ways in which molecular techniques might be employed in behavioral and ecological studies of primates (e.g., for conducting "molecular censuses" of unhabituated populations, for studying disease and host-parasite interactions, or for tracking seed fate in studies of seed dispersal) and by providing a brief introduction to the burgeoning field of nonhuman primate behavioral genetics.

“…In recent years, however, new technological breakthroughs such as nightscopes and radiotelemetry, among others, have allowed scientists to observe these primates using systematic sampling techniques [Gursky, 1998[Gursky, , 2003Atsalis, 2000;Nekaris, 2001Nekaris, , 2003Pullen et al, 2000;Radespiel, 2000;Sterling et al, 2000;Bearder et al, 2003;Radespiel et al, 2002]. These recent studies are also due to the tremendous perseverance among this new group of scientists who have renewed the initial view that it is important to study the variation present in the nocturnal prosimian primates if we are to ever make broad correlations concerning ecology and behaviour.…”

“…Heteropaternity in polytocous species is a consequence of multiple mating by females whose ova, released in a single estrus cycle, are fertilized by sperm from different males [7][8][9][10]. Sperm of different males compete for fertilization while they are stored and mixed within the female oviduct after multiple matings.…”

Male tigers (Panthera tigris altaica) in captivity copulate alternatively with an estrous female, suggesting a potential for heteropaternity as an effective reproductive strategy to maximize genetic diversity of offspring. We analyzed microsatellites to test and compare the genetic output of multiple male mating (simultaneous polyandry) and single male mating (monogamy) with a female in a captive population. Simultaneous polyandry resulted in heteropaternity in 66.7% observed litters. No significant differences between parental populations and between offspring populations were detected in the number of alleles (A), expected heterozygosity (H e ), number of effective alleles (N e ) per locus and standard individual heterozygosity (SH) (P>0.05 for all 4 indexes). Comparisons showed no significant reduction of A, H o , H e and SH from parental population to offspring population for the two mating modes (P>0.05) except for SH in polyandrous families (P=0.029). However, such reduction was equivalent to single mating families when the influence of relatedness was eliminated using effective SH (E SH ) (P>0.05). These results highlight an alternative strategy for managing captive populations of tiger and other wild felids in which animals are combined at one location allowing for copulation by multiple males to encourage heteropaternity in favor of maintained genetic diversity among offspring.
