Defensive responses of Brandt’s voles (Lasiopodomys brandtii) to stored cat feces
Predator odors are non-intrusive natural stressors of high ethological relevance. Animals are daily challenged with stressors of varying intensity and it is essential for their survival to respond to a wide range of threats. Behavioral and hormonal responses and changes in the level of medial hypothalamic c-fos mRNA were examined in Brandt’s voles (Lasiopodomys brandtii) […]
Defensive responses of Brandt’s voles (Lasiopodomys brandtii) to chronic predatory stress
Predator odors are non-intrusive natural stressors of high ethological relevance. The objective of this study was to investigate the processing of a chronic, life-threatening stimulus during repeated prolonged presentation to Brandt’s voles. One hundred and twenty voles were tested by repeated presentation of cat feces in a defensive withdrawal apparatus. Voles exposed to feces for […]
