- Abstract
This study aimed at contributing to the phenotypic characterization of Cephalophus monticola (blue duiker) in 3agroecological zones of the Southern Cameroon region. A total of 22 morphological data were collected on 180 adult blue duikers and 15 cranial measurements on 60 skulls using the opportunistic approach. Data analyses were performed using the descriptive statistics through the software SPSS version 21.0 and XLSTAT-Pro version 7.5.2. From the findings, it appears that the biometric characteristics of the head were not influenced by the agro ecological factor. However, horn width (HW) presents a large variation in zone V (CV=113.27%) which the female having an CV=96.55%. Concerning the trunk, the Body length (BL) expresses a large dispersion with the respective values (in cm): (71.78 ± 12.46); (69.13 ± 13.66) and (66.53 ± 15.54) respectively to agroecological zones III, IV and V. Three traits, tail length (TL) and fore leg girth (FLG) showed significant differences (P<0.05). The principal component analysis (PCA) displays the level of genetic variability of blue duiker through biometric characters. Then, it was observed two levels of genetic of variability according to the axes F1 (46,94%) and F2 (10,81%). The biometric traits tended to discriminate blue duikers in the three agroecological zones. This could be interesting for further investigations involving molecular tools for population genetics.
