Breeding status and social environment differentially affect the expression of sex steroid receptor and aromatase mRNA in the brain of female Damaraland mole-rats

Voigt, Cornelia; Gahr, Manfred; Leitner, Stefan; Lutermann, Heike; Bennett, Nigel Charles (BioMed Central, 2014-05-08)

INTRODUCTION: The Damaraland mole-rat (Fukomys damarensis) is a eusocial, subterranean mammal, which exhibits an extreme reproductive skew with a single female (queen) monopolizing reproduction in each colony. Non-reproductive ...
Differential regulation of Kiss1 gene expression by oestradiol in the hypothalamus of the female Damaraland mole-rat, an induced ovulator

Voigt, Cornelia; Gahr, Manfred; Bennett, Nigel Charles (Elsevier, 2023-09)

Kisspeptin, a product of the Kiss1 gene is considered a potent stimulator of gonadotropin release, by interacting with its receptor, the G protein-coupled receptor 54. Kiss1 neurons are known to mediate the positive and ...
Duets recorded in the wild reveal that interindividually coordinated motor control enables cooperative behavior

Hoffmann, Susanne; Trost, Lisa; Voigt, Cornelia; Leitner, Stefan; Lemazina, Alena; Sagunsky, Hannes; Abels, Markus; Kollmansperger, Sandra; Ter Maat, Andries; Gahr, Manfred (Nature Publising Group, 2019)

Many organisms coordinate rhythmic motor actions with those of a partner to generate cooperative social behavior such as duet singing. The neural mechanisms that enable rhythmic interindividual coordination of motor actions ...
Seasonal and diurnal variation of vocal behaviour in duetting White-browed Sparrow Weavers

Voigt, Cornelia; Leitner, Stefan; Gahr, Manfred; Ter Maat, Andries (Springer, 2021-10)

Singing in tropical and Southern hemisphere birds often occurs throughout the year in the form of duetting, which is thought to be associated with year-round territoriality. White-browed Sparrow Weavers (Plocepasser mahali) ...
