In polygynous mammals, the status of many males does not allow them to have a high social rank and theory predicts selection for alternative mating tactics. Alternative tactics were suggested to explain discrepancies between mating and paternity successes in several pinniped species. However, information on alternative tactics in fur seals is limited. Here, we focus on the polygynous New Zealand fur seal, Arctocephalus forsteri, predicting that competition for females is likely to cause a diversification of male mating tactics and that non-territorial tactics can yield reproductive success. We describe the behaviour of 38 males in a medium to large colony. Paternity success was assessed using CERVUS and PASOS, from a pool of 82 pups sampled at the study site and at neighbouring breeding areas. To see whether size is correlated with mating tactic, the length of 17 males was estimated using photogrammetry. Cluster analysis identified three male behavioural profiles: one corresponding to large territorial males and two illustrating alternative tactics employed by smaller non-territorial males. Of the 13 pups born at the study site that were assigned a father, eight were sired by three territorial males and five were sired by non-territorial males. Our study highlights that holding a territory is not a necessary condition for reproductive success in all otariids.

The Relationship

AbstractThe macaques have been a central focus of research designed to illuminate the interrelationship of behaviour and patterns of genetic transmission in non-human primates. Due to unique aspects of the socio-sexual behaviour and reproductive biology of stumptailed macaques (Macaca arctoides), we hypothesized a stronger relationship between male status and reproductive success than has been documented in other macaque species. The relationship between male social rank and success in siring offspring was examined for a sequence of 27 infants born over an 8-year period (1984-1992) in a large captive social group. Paternity of 25 of the 27 infants (all those still living at the time of testing) was confirmed with the use of "DNA profile tests" using mini-satellite, multi-locus probes in collaboration with Drs. CASNA and GERGITS of Therion Corp. Results showed that each of three consecutive alpha males was effective in achieving a virtual monopoly in siring offspring during his tenure, with one exception possibly related to inbreeding avoidance. Although patterns of sexual behaviour are not emphasized in this report, behavioural observations over the past six years support the findings of other researchers regarding the

Space Lab 3 (SL-3) was flown on Shuttle Challenger providing an opportunity to measure the effect of spaceflight on rat testes. Cannon developed the idea that organisms react to unfavorable conditions with highly integrated metabolic activities. Selye summarized the manifestations of physiological response to nonspecific stress and he pointed out that atrophy of the gonads always occurred. Many papers have been published showing the effects of social interaction, crowding, peck order and confinement. Flickinger showed delayed testicular development in subordinate roosters influenced by group numbers, social rank and social status. Christian reported increasing population size in mice resulted in adrenal hypertrophy, inhibition of reproductive maturation and loss of reproductive function in adults. Sex organ weights also declined. Two male dogs were flown on Cosmos 110 for 22 days. Fedorova reported an increase of 30 to 70% atypical spermatozoa consisting of tail curling and/or the absence of a tail.
