Behavioral and physiological responses to fruit availability of spider monkeys ranging in a small forest fragment.
Bottom Line: This might result in behavioral and dietary adjustments, especially because fruit availability is frequently reduced in fragments.Food scarcity can result in elevated physiological stress levels, and chronic stress often has detrimental effects on individuals.The atypical grouping pattern of the study groups seems to be less effective at mitigating contest competition over food resources than more typical fission-fusion patterns.

Mentions: Overall, the full model (Model 1) estimating the influence of fruit availability on FGCM levels differed significantly from the model (X2 = 141.07, df = 7, P < 0.0001, N = 366 fecal samples). More specifically, fruit availability had a positive effect on FGCM levels (LMM: Estimate ± SE: 0.22 ± 0.03, T = 5.82, PMCMC = 0.0001; Table4, Fig. 3). The full model (Model 2) investigating the influence of aggression rate on FGCM levels did not differ from the model (X2 = 3.34, df = 3, P = 0.34, N = 97 fecal samples).
