(Elsevier, 2018-01)
In many mammal species, androgen levels in males are elevated during periods of mating activity, often to facilitate aggressive behavior between males over access to fertile females. However, this pattern might be less ...

Medger, Katarina; Bennett, Nigel Charles; Ganswindt, Stefanie Birgit; Ganswindt, Andre; Hart, Daniel William
(Springer, 2019-05)
Colonies of naked mole-rats (Heterocephalus glaber, NMRs) are characterised by an extreme skew in lifetime reproductive success with only one female and one to three male consorts in a colony. The rest of the individuals ...

(Royal Society, 2019-02)
The phenotype of parents can have long-lasting effects on the development of offspring as well as on their behaviour, physiology and morphology as adults. In some cases, these changes may increase offspring fitness but, ...

(Elsevier, 2020-09)
The social environment of animals can have profound implications on their behaviour and physiology. Naked mole-rats (Heterocephalus glaber) are highly social with complex dominance hierarchies that influence both stress- ...

(Wiley, 2021-03)
The southern ground‐hornbill (SGH) is a cooperatively breeding bird endemic to eastern and southern Africa, but is endangered in its southern distributional range. The national conservation restoration program harvests ...

(The Royal Society, 2018-05)
Elevated prolactin (PRL) has been associated with the expression of social and cooperative behaviours in a number of vertebrate species, as well as suppression of reproduction. As social mole-rats exhibit both of these ...

Scheun, Juan; Nowack, Julia; Bennett, Nigel Charles; Ganswindt, Andre
(Springer, 2016-02)
Steroid hormones play an important role in
female reproductive physiology and behaviour and are
often used to monitor important female reproductive events.
However, such studies are often attempted on captive ...

(Springer, 2015-10)
Urbanisation has become a severe threat to pristine natural areas, causing habitat loss and affecting indigenous animals. Species occurring within an urban fragmented landscape must cope with changes in vegetation type as ...

(Elsevier, 2018-01)
One of the primary sources of perceived stress is the social environment of an animal and the interactions with conspecifics. An essential component of the response to a stressor is the activation of the hypothalamic–pit ...

De Bruin, Ruan; Ganswindt, Andre; Bennett, Nigel Charles; Medger, Katarina
(Elsevier, 2018-05)
Photoperiod and food availability often interact in the regulation of reproductive development in seasonal environments. We tested the effects of a 10% food restriction and short- (SD) and long-day (LD) photoperiods on ...

(The Royal Society, 2017-09)
In cooperative breeders, aggression from dominant breeders directed at subordinates may raise subordinate stress hormone (glucocorticoid) concentrations. This may benefit dominants by suppressing subordinate reproduction ...

(Nature Publising Group, 2018-10-02)
An intricate network of crevices adorns the skin surface of the African bush elephant,
Loxodonta africana. These micrometre-wide channels enhance the effectiveness of thermal
regulation (by water retention) as well as ...

Medger, Katarina; Bennett, Nigel Charles; Lutermann, Heike; Ganswindt, Andre
(Elsevier, 2018-09)
Dominant females of cooperative breeding species often use aggression to suppress reproduction of subordinate females, resulting in subordinates experiencing stress-related increases in glucocorticoid levels, which may ...

Scheun, Juan; Bennett, Nigel Charles; Nowack, J.; Laver, Peter N.; Ganswindt, Andre
(NRC Research Press, 2017-07)
In seasonal breeders, periods of reproductive activity often coincide with high levels of glucocorticoids. We studied seven male and seven female African lesser bushbabies (Galago moholi A. Smith, 1836) over two mating ...

(Wiley, 2018-06)
Fission‐fusion social societies allow animals to respond in a flexible manner to environmental changes by adapting the size and composition of a group. Although group members change frequently in these systems, associations ...

(Elsevier, 2020-07)
Non-invasive methods for measuring glucocorticoids and their metabolites are frequently used in ecological, behavioural and physiological studies of mammals. Using faeces, urine and other matrices for such a measurement ...
