Male-biased parasite loads, which are common in vertebrates, could be a consequence of
sexual selection, and for species that group, the costs of parasites could vary with group size …

Parasites can be detrimental to the health, longevity, and reproduction of their hosts, but these
costs are rarely quantified in nature. We removed ectoparasites and endoparasites from …

The Cape ground squirrel (Xerus inauris) of southern Africa is a tropical species that does
not hibernate. Field observations using scan and all‐occurrence sampling revealed that this …

Ecologists often rely on unique natural markings to identify individual free-ranging animals
without disturbing them. We developed a computer-aided photo-identification system for …

The Cape ground squirrel,Xerus inauris, is a social species of ground squirrel inhabiting the
arid areas of southern Africa. The high degree of sociality in this species is due to the …

The doubly labelled water (DLW) technique and indirect calorimetry measurement enable
measurement of the daily energy expenditure (DEE, kJ/day), resting metabolic rate (RMR, kJ/d…

The Cape ground squirrel is a highly social, tropical ground squirrel that does not hibernate,
suggesting that female receptivity could be scattered throughout the year. Males in this …

Hibernating ground squirrels rely on a short active period for breeding and mass accrual, and
are thus vulnerable to extreme climate events that affect key periods in their annual cycle. …

Female Cape ground squirrels Xerus inauris live in matrilineal kin groups in which the number
of reproductive positions is limited to three females. Field observations on a population in …

To examine the effects of climate and hibernation on reproductive patterns, I compared tropical
and temperate species of ground and tree squirrels. I studied the reproductive biology of …
