The effects of familiarity and reproductive status on olfactory discrimination by female Cape ground squirrels (Xerus inauris)
The ability to differentiate among conspecifics on the basis of genetic relatedness can be advantageous in kin and mate selection. Selection of mates that are of an intermediate degree of relatedness maximizes the propagation ...
Anti-snake behaviour in a facultative cooperative breeder, the Cape ground squirrel
(Brill Publishers, 2014-10)
Predator harassment is an anti-predator behaviour that may increase an individual’s risk of predation, as individuals approach, threaten and harass a potential predator, yet this behaviour is still not well understood. The ...
Both familiarity and kinship influence odour discrimination by females in a highly social African ground squirrel
Kin recognition can be important in species where inbreeding avoidance or nepotism (favouritism towards kin) rely on identifying kin, particularly in species with alloparental care. The mechanisms that facilitate kin ...
Trade-offs between immunity and testosterone in male African ground squirrels.
(The Company of Biologists, 2018-08-23)
The immunocompetence handicap hypothesis (ICHH) proposes that testosterone has both beneficial effects on male reproductive potential and negative effects by suppressing the immune system. However, support for the ICHH ...
Cape ground squirrels as ecosystem engineers: modifying habitat for plants, small mammals, and beetles in the Namib Desert
Burrowing and foraging of semi-fossorial rodents can affect species distribution and composition. Ground squirrels dig large burrow systems for refuge from predators and temperature extremes. Burrowing and foraging around ...
'Failure to launch': Is there a reproductive cost to males living at home?
(Oxford Academic, 2015-03-27)
Differential reproductive success commonly reflects variations in reproductive physiology, behavior, and morphology. In some species, competition among males results in the evolution of alternative reproductive tactics ...
