Sexual selection theory predicts competitive males and choosy females. Nevertheless, since molecular marker‐based studies, paternity outside the expected mating patterns has increasingly been described. Even in highly polygynous systems, where paternity is expected to be strongly skewed towards large, dominant males, alternative mating tactics have been suggested. We examined reproductive success in the polygynous Galápagos sea lion (Zalophus wollebaeki). Semiaquatic territoriality allows… 
Paternity in eastern grey kangaroos: moderate skew despite strong sexual dimorphism
Assessment of the distribution of paternities and quantified skew in male reproductive success in 2 populations of a marsupial with strong sexual dimorphism, the eastern grey kangaroos over 5 years suggests an unexpectedly low reproductive skew.
Activity Predicts Male Reproductive Success in a Polygynous Lizard
It is suggested that the most successful male strategy is a form of endurance rivalry in which active mate searching and interactions with females have the greatest fitness benefits.
The Cost of Male Aggression and Polygyny in California Sea Lions (Zalophus californianus)
It is shown that both male and female reproductive behavior during the breeding season (June–August) affect female fecundity, a vital rate that is an important determinant of population growth rate and viability.
Weak Polygyny in California Sea Lions and the Potential for Alternative Mating Tactics
Overall, considerably lower variation in male reproductive success than expected is found in a species that exhibits behavior associated with strongly polygynous mating, which may result from heightened mobility among receptive females in the Gulf of California, which reduces the ability of males to monopolize groups of females.

    Ethology and Behavioral Ecology of Otariids and the Odobenid
  • 2021
Testing the literature on paternity for otariids found that size of harem did correlate with paternity by territorial males but the slope was significantly lower than expected from behavioural estimations; differences in paternity between territorial and satellites males were not statistically significant in most studies.
Behaviour and characteristics of mating polar bears (Ursus maritimus) in the Beaufort Sea, Canada
Paired females had significantly higher labial development than lone females, suggesting that labial swelling is heightened during mating, and observed characteristics suggest a polygynous mating system in polar bears, providing further insight into potential mating system variation across their range.
How Attractive Is the Girl Next Door? An Assessment of Spatial Mate Acquisition and Paternity in the Solitary Cape Dune Mole-Rat, Bathyergus suillus
It is suggested that above-ground movement should not be ignored in the consideration of mate acquisition behaviour of subterranean mammals, and high levels of multiple paternity have not been found in other solitary mole-rat species.
Being on time: size-dependent attendance patterns affect male reproductive success
Tide line versus internal pools: mating system and breeding success of South American sea lion males
This is the first study showing the first evidence in otariids for the coexistence of two distinct mating systems in an otariid rookery related to breeding location, and it is shown that close kin males were only present at the tide line, suggesting a fine scale kin structure in the study area.


Paternity analysis shows experience, not age, enhances mating success in an aquatically mating pinniped, the Weddell seal (Leptonychotes weddellii)
Weddell seals at Turtle Rock show a modest degree of polygyny with the greatest number of pups sired by any individual male in a single season equalling 5 or ∼10% of the pups born, and aquatic mating reduces the ability of males to monopolize females, and thereby increases equity in mating success.
Analysis of male reproductive success in the Antarctic fur seal Arctocephalus gazella, an otariid described behaviorally as being highly polygynous, by combining a microsatellite paternity analysis spanning seven consecutive breeding seasons with detailed behavioral data on both sexes found no evidence of alternative male reproductive tactics such as aquatic or sneaky terrestrial mating.
Seasonal changes of vocal rates and their relation to territorial status in male galapagos sea lions (Zalophus wollebaeki)
The results suggest that vocalizations are important in male–male interactions, are relevant in territorial disputes and are used as a proxy for females to assess a male’s quality.
Male mating success and paternity in the grey seal, Halichoerus grypus: a study using DNA fingerprinting
Overall, DNA typed males were more dominant, maintained positions amongst the females for longer, and accounted for disproportionately more paternities than untyped males, however, the reproductive success of the typed males is not as great as their behavioural domination of copulatory opportunities would suggest.
The mating systems of pinnipeds and marine iguanas : convergent evolution of polygyny
It is hypothesize that marginal males, through continuous sexual harassment of females that stay outside territories, have exerted pressure towards the evolution of female gregariousness.
Effectiveness of territorial polygyny and alternative mating strategies in northern fur seals, Callorhinus ursinus
The results indicate that terrestrial resource-defense polygyny is the major mating system in this species and that nonassociated paternity occurs mostly as a result of alternative mating strategies of less successful males.
A multivariate analysis of phenotype and paternity in male harbor seals, Phoca vitulina, at Sable Island, Nova Scotia
Understanding the links between phenotype and reproductive success is critical to the study of the evolution of mating systems and life-history patterns. We examined the relationship between
Extreme polygyny among southern elephant seals on Sea Lion Island, Falkland Islands
A comparatively high variance in resource holding potential among males, differences in male social behavior, and a small tidal cycle limiting peripheral male access during female departure from the harem at this colony may be important factors leading to the comparativelyhigh variance in male reproductive success at Sea Lion Island.
Social Dominance and Male Breeding Success in Captive White-Tailed Deer
The relationship between social dominance and male breeding success may be more complex than previously thought and should account for considerable individual heterogeneity among males in their ability to sire offspring.
Males in the shade: habitat use and sexual segregation in the Galápagos sea lion (Zalophus californianus wollebaeki)
This work investigated terrestrial habitat use and sexual segregation in a tropical otariid, the Galápagos sea lion (Zalophus californianus wollebaeki), where most of the hypotheses can be ruled out a priori.
