These contact calls are acoustically distinctive and variable in rate across individuals, yet, information on which factors influence close calling behavior is missing. During foraging, individuals emit close calls that help maintain group cohesion. Our findings suggest that meerkat close calling behavior conveys information regarding the sex and social category of the caller, but shows no association with fGCM concentrations. Windy conditions were associated with significantly higher call rates during the non-reproductive season. However, the association between physiological parameters, particularly stress hormone levels, and vocal behavior is still not well understood. To disentangle the effects of these factors on vocal behavior, we analyzed sound recordings and assessed fGCM concentrations in 64 wild but habituated meerkats from 9 groups during the reproductive and non-reproductive seasons.
Meerkat close calling patterns are linked to sex.
g.Among immature dugongs, the prevalence of tusk injury was greatest among small solitary calves, suggesting that young dugongs without maternal protection are more vulnerable to male aggression.e.The assessment of physiological parameters associated with stress is imperative for an understanding of the health and reproduction of wildlife populations ( Boonstra, 2005; Reeder and Kramer, 2005 ), particularly for a vulnerable species, such as the dugong.Extensive tusk rake wounds on the dorsum of both sexes present physical evidence of injurious conflicts.Climatic factors and food availability have both been reported to affect glucocorticoid output in a variety of species ( Muller and Wrangham, 2004; Weingrill et al., 2004 ), and this response is generally most pronounced during cold seasons in response to energy demand ( St Aubin et al. A Journal of the Reign of Queen Victoria.

But he was loathed as an invader from the north who burned heretics and acquired their property in equal measure.In 1271 Guy and Simon arrived in Viterbo, where a papal election was in process.The brothers were disowned, with the younger Simon dying later that year, but Guy got off with no more than house arrest.The next year Edward escaped his captors, raised an army, and was determined not to repeat his stupidity at Lewes.Deserted by the conceited and xenophobic earl of Gloucester, Simon found himself trapped at Evesham in August 1265.This seems to have been based on his father?s reputation, however, because Simon himself had no record of major engagements before coming to England.Henry III was by nature cosmopolitan and pursued a continental policy to maintain English influence across the Channel.
