We investigated scent marking behaviour in the yellow mongoose Cynictis penicillata, focusing on a low-density population where all offspring dispersed upon reaching sexual maturity. Dominant males…
Differences in alarm vocalizations of sympatric populations of the whistling rats, Parotomys brantsii and P. littledalei (Rodentia: Muridae)
- A. L. Roux, T. P. Jackson, M. Cherry
- Biology
- 1 June 2002
The data support the acoustic adaptation hypothesis in that P. littledalei, which inhabits a more closed habitat, has calls which are lower in frequency than P. brantsii calls, but contrary to the hypothesis, P.brantii calls do not show greater frequency modulation.
The vocal repertoire in a solitary foraging carnivore, Cynictis penicillata, may reflect facultative sociality

This study of the vocal repertoire of the yellow mongoose is, to the authors' knowledge, the most complete to have been conducted on a facultatively social species in its natural habitat.
Human observers impact habituated samango monkeys’ perceived landscape of fear.

The results suggest that human observers lower monkeys’ perceived risk of terrestrial predators and, thereby, affect their foraging decisions at or near ground level, which has significant implications for future studies of responses to predation risk based on habituation and observational methods.
Vigilance behaviour and fitness consequences: comparing a solitary foraging and an obligate group-foraging mammal

It is suggested that foraging group size in herpestids is constrained by species-distinct vigilance patterns, in addition to habitat and prey preference.

This review examines the current — highly constrained — state of knowledge about the endocrine basis of carnivore paternal investment and attempts to link changes in androgen and glucocorticoid levels with variation in direct and indirect paternal care behaviour making specific predictions regarding the way forward.
