| Abstract: | Biometric measurements of horn, body and physiological variables of 35 Alpine ibex, Capra ibex ibex, (14 females and 21 males, age range: 2-15 years) were analysed in relation to gender and area of origin. Moreover, for the first time hair cortisol concentration was evaluated in this species. The ibexes were live-captured in spring in the Maritime Alps Natural Park. All the horn and body morphometric measurements were significantly different between genders and a statistical difference was found between horn and body data considering the area of origin of ibexes, with the exception of horn circumference and height as well of body and hock length. Among the physiological variables, female ibex showed higher heart rate and glycemia, but tended to have lower respiratory rate than male. The mean hair cortisol concentration was 22.40±1.44 pg/mg (±SE). A different distribution was described for the male hair cortisol concentrations compared to that in females. Obtained data indicate that the geographical area where Alpine ibex lives could affect the endurance of an ibex population but further investigations are needed to understand if intra- and inter-specific competition and different environment could be the basis of the HPA axis activation. Hair cortisol evaluation together with biometric values could be an interesting way to obtain information on the adaptation that the animal attempts to reach in relation to environmental factors and pursuing organism homeostasis. This feature could be important in attempting to preserve wildlife biodiversity that also depends from the state of animal welfare. |
