Changes in expression of appetite-regulating hormones in the cunner (Tautogolabrus adspersus) during short-term fasting and winter torpor

Feeding in vertebrates is controlled by a number of appetite stimulating (orexigenic, e.g. orexin and neuropeptide Y, NPY) and appetite suppressing (anorexigenic, e.g. cholecystokinin, CCK and cocaine- and amphetamine-regulated transcript, CART) hormones. Cunners (Tautogolabrus adspersus) survive the winter in shallow coastal waters by entering a torpor-like state, during which they forgo feeding. In order to […]

Physiological and behavioural responses of a small heterothermic mammal to fire stimuli

The predicted increase of the frequency and intensity of wildfires as a result of climate change could have a devastating impact on many species and ecosystems. However, the particular physiological and behavioural adaptions of animals to survive fires are poorly understood. We aimed to provide the first quantitative data on physiological and behavioural mechanisms used […]
