Patterns of behaviour, group structure and reproductive status predict levels of glucocorticoid metabolites in zoo-housed ring-tailed lemurs, Lemur catta. Koninklijke Maatschappij voor Dierkunde van Antwerpen
In ring-tailed lemurs, Lemur catta , the factors modulating hypothalamic-pituitaryadrenal (HPA) activity differ between wild and semi-free-ranging populations. Here we assess factors modulating HPA activity in ring-tailed lemurs housed in a third environment: the zoo. First we validate an enzyme immunoassay to quantify levels of glucocorticoid (GC) metabolites in the faeces of L. catta . We determine the nature of the female-female dominance ...
