Can faecal glucocorticoid metabolites be used to monitor body condition in wild Upland geese Chloephaga picta leucoptera?

Autor: Petra Quillfeldt, Alexandra Kuchar, David Joachim Gladbach, Anja Gladbach, Martina Koch, Erich Möstl

Publikováno v: Behavioral Ecology and Sociobiology

The measurement of faecal glucocorticoid metabolites is used as a non-invasive technique to study stress in animal populations. They have been used most widely in mammals, and mammalian studies have also treated issues such as sample stability and st

Measurement of cortisol in dog hair: a noninvasive tool for the diagnosis of hypercortisolism

Autor: Alexandra Kuchar, Erich Möstl, Claudia Ouschan

Publikováno v: Veterinary dermatology. 24(4)

Background The clinical signs of hyperadrenocorticism (hypercortisolism) in dogs are known to be caused by chronic overexposure to glucocorticoids. The quantification of cortisol in serum, saliva or urine reflects the cortisol concentration at the ti

In the field as well as in the laboratory, human-generated stress responses are reduced in adult animals previously habituated to humans in comparison to non-habituated individuals. In birds, yolk steroid levels vary with maternal environment and con

Effect of giving birth on the cortisol level in a bonobo groups' (Pan paniscus) saliva

Autor: Dieter Selzer, Verena Behringer, Alexandra Kuchar, Katja Hachenburger, Wolfgang Clauss, Erich Möstl

Publikováno v: Primates; journal of primatology. 50(2)

This study documents the cortisol levels in the saliva of a bonobo group, especially that of a bonobo female which had given birth for the first time. During a long study in Zoological Garden Frankfurt, Germany, a bonobo baby was born on 3 August 200

Corticosterone metabolites in blue tit and pied flycatcher droppings: Effects of brood size, ectoparasites and temperature

Autor: Alexandra Kuchar, José Luis Osorno, Juan Moreno, Erich Möstl, Judith Morales, Josué Martínez de la Puente, Gustavo Tomás, Elisa Lobato, Santiago Merino

Publikováno v: Hormones and Behavior, 53(1), 295-305. Academic Press

The hypothalamic-pituitary-adrenal (HPA) axis of birds induces the secretion of corticosterone (CORT) as a response to different ecological variables. In this study we tested experimentally if manipulations of brood size or ectoparasitism led to subs
