In environments with higher pathogen load, the immune system should experience greater challenges and, therefore, investment in maintaining it should be higher. The biomarker neopterin allows monitoring of innate immune responses, and is therefore an ideal tool to investigate the effects of ecological variables on the immune system. Here, we compared urinary neopterin levels of apparently healthy chimpanzees without acute symptoms of sickness across two environments: in captivity (22 zoos) and in the wild (two populations). %K Ecoimmunology; Immune respons; Energy allocatio; Costs; Captive and wild living %J BMC Zoology %V 4 %] 2 %I Springer %C Berlin %@ 2056-3132
