“…e season from spring to autumn prior to rut has greater e ect on the timing of parturition of caribou than conditions at late gestation (Adams & Dale, 1998). ere are comparable ndings in reindeer (Holand et al, 2004). e results suggest that there could be a way to predict the on-set of rutting from the weather statistics and consequently the optimum time for the herders to gather reindeer.…”

e factors causing variation in birth date and birth weight were analysed from the data from an experimental reindeer herd consisting of 1136 calves with parental information. e traits had coe cient of variation of 37 and 14%, respectively. e variation in both traits was a ected by year and sex (male calves heavier) and by management factors, such as the age distribution of females and males. Early calving results from the use of older breeding males and is most apparent in prime age females. In both traits the heritability was moderate (0.23 and 0.24) with a high proportion of maternal genetic variation (0.23) in birth weight. e North Atlantic Oscillation (NAO) indices, summarizing the major weather conditions prior to rut, explained part of the annual variation in the traits. e amount of total genetic variation in relation to trait mean, or the evolvability, was 21% in birth date and 10% in birth weight indicating that selection could successfully be used to improve herd productivity and that the traits have substantial potential for adapting to possible changing environmental conditions. e results on genetic correlations imply that selection on calf 's birth weight leads on one hand to calves being born earlier and on the other hand to dams with later parturition.

“…Our study underlines the fact that ample food provisioning in captivity does not automatically result in homogeneous body condition. Holand et al (2004) found in an experimental herd of reindeer that high-ranking females gained weight during winter, whereas low-ranking ones lost weight. However, free-ranging red deer females did not suffer weight loss from interference competition at artificial feeding sites in winter, and rank and feeding time were correlated only among top-ranking females (Veiberg et al 2004).…”

“…A probable causal pathway is that rank determines maternal weight and fatness during conception and gestation, which for a large part determine the offspring's weight at birth. In addition, high maternal rank may mediate a priority of female access to the bull or earlier postbirth resumption of oestrus and early birthdate (as in reindeer: Holand et al 2004), resulting in a higher offspring weight at weaning. Green & Rothstein (1993) found that for both sexes, early born yearlings ranked higher than their later born peers.…”

“…Current characteristics of an individual, such as age or dominance rank, regardless of genetic, maternal, or other contributions to these traits, also influence fitness components in most species (Abbott et al, 2003;Alberts et al, 2003;Alberts et al, 2006;Clutton-Brock, 1988;Côté and Festa-Bianchet, 2001;Förslund and Pärt, 1995;Holand et al, 2004;Holekamp et al, 1996;von Holst et al, 2002;Packer et al, 2000;Romero, 2004;Sapolsky, 2005). Furthermore, differences in GC levels are also sometimes associated with these current characteristics of an individual (Creel, 2001;Goymann and Wingfield, 2004;Sapolsky and Altmann, 1991).…”

Dominance status and reproductive experience are maternal characteristics that affect offspring traits in diverse taxa, including some cercopithecine primates. Maternal effects of this sort are widespread and are sources of variability in offspring fitness. We tested the hypothesis that maternal dominance rank and reproductive experience as well as a male's own age and dominance rank predicted chronic fecal glucocorticoid (fGC) concentrations in 17 subadult wild male baboons, Papio cynocephalus (median age 6.5 years), in the Amboseli basin, Kenya. Among these variables, maternal dominance rank at a subadult male's conception was the sole significant predictor of the male's fGC and accounted for 42% of fGC variance; sons of lower ranking mothers had higher fGC than did those of high ranking mothers. This result is striking because subadult male baboons are approximately 4-6 years past the period of infant dependence on their mothers, and are larger than and dominant to all adult females. In addition, many males of this age have survived their mothers' death. Consequently, the influence of maternal dominance rank persisted well beyond the stage at which direct maternal influence on sons is likely. Persistence of these major maternal influences from the perinatal period may signal organizational effects of mothers on sons' HPA axis. Although shortterm, acute, elevations in GC are part of adaptive responses to challenges such as predators and other emergencies, chronically elevated GC are often associated with stress-related pathologies and, thereby, adverse effects on fitness components.
