Essay --

In the terra firma of animals, those at the top of a sureness pecking order are much beneficial than low-ranking animals1. However, the costs associated with being at the top of a hierarchy remain controversial1. Different studies reported confounding findings on whether dominant or subordinate animals experienced greater attempt levels2-3. Furthermore, Sapolsky4-5 suggested that hierarchy stability could potentially influence the stress levels experienced by high-ranking olive baboons. wedded the results from previous literatures, Gesquiere et al.1 created a research disbelief asking how do potent savannah baboons (Papio cynocephalus) respond to rank-related stress during permanent and precarious hierarchy? They hypothesized that high-ranking males would acquaint higher levels of analyzeosterone and glucocorticoid completely when a hierarchy was unstable1. From this hypothesis, they predicted that during the month with unstable hierarchy, the high-ranking male savan nah baboons would exhibit greater faecal testosterone (fT) and fecal glucocorticoid (fGC) levels than other males within the hierarchy however, much(prenominal) phenomenon would not be sight during the month with a stable hierarchy1. To test this prediction, they conducted a long-term work on wild savannah baboons in Amboseli, Kenya1. Over a 9-year period, ecological, behavioural and physiological data including fT and fGC were still monthly from 125 self-aggrandising males1. General linear mixed models (GLMMs) were utilize to predict the dependent variables, fT and fGC, based on predictor variables including individual(a) rank, hierarchy stability, and an interaction mingled with the two1. Gesquiere et al.1 defined a stable hierarchy as the month when the males with the highest 3 ranking were the same as those in the p... ...nction9. However, a bloodsucking stretch in an individual was not only associated the individual resistive matter but also with how likely it is subject to the infectious agents9. Hence, parasitic gist would not be an accurate indication of individual immune function9. In contrast, leukocyte count, which was used in another(prenominal) translate to investigate immune function, could deal as a better index number than parasitic load10. In conclusion, sacking beyond the study conducted by Gesquiere et al., the proposed sample is significant because it can supply more insights into whether or not suppress immune function is another potential cost for being at the top of the dominance hierarchy. Also, victimization leukocyte count as an indicator of immune function instead of parasitic load, the proposed experiment can further realise the contradicting findings reported by different literatures. Essay -- In the world of animals, those at the top of a dominance hierarchy are more beneficial than low-ranking animals1. However, the costs associated with being at the top of a hierarchy remain controversial 1. Different studies reported contradictory findings on whether dominant or subordinate animals experienced greater stress levels2-3. Furthermore, Sapolsky4-5 suggested that hierarchy stability could potentially influence the stress levels experienced by high-ranking olive baboons. Given the results from previous literatures, Gesquiere et al.1 created a research question asking how do male savannah baboons (Papio cynocephalus) respond to rank-related stress during stable and unstable hierarchy? They hypothesized that high-ranking males would exhibit higher levels of testosterone and glucocorticoid only when a hierarchy was unstable1. From this hypothesis, they predicted that during the month with unstable hierarchy, the high-ranking male savannah baboons would exhibit greater fecal testosterone (fT) and fecal glucocorticoid (fGC) levels than other males within the hierarchy however, such phenomenon would not be observed during the month with a stable hierarchy1. To test this predic tion, they conducted a long-term study on wild savannah baboons in Amboseli, Kenya1. Over a 9-year period, ecological, behavioral and physiological data including fT and fGC were collected monthly from 125 adult males1. General linear mixed models (GLMMs) were used to predict the dependent variables, fT and fGC, based on predictor variables including individual rank, hierarchy stability, and an interaction between the two1.

However, a parasitic load in an individual was not only associated the individual immune function but also with how likely it is exposed to the infectious agents9. Hence, parasitic load would not be an accurate indicator of individual immune function9. In contrast, leukocyte count, which was used in another study to investigate immune function, could serve as a better indicator than parasitic load10. In conclusion, go ing beyond the study conducted by Gesquiere et al., the proposed experiment is significant because it can provide more insights into whether or not suppressed immune function is another potential cost for being at the top of the dominance hierarchy. Also, using leukocyte count as an indicator of immune function instead of parasitic load, the proposed experiment can further elucidate the contradicting findings reported by different literatures.
