Variación intraespecífica e individual de los pelos de mamíferos del Estado de México: implicaciones en la identificación interespecífica

摘要: This research project determined the variation in dorsal guard hair among members of same specie. Besides, a single member different regions was also assessed. The measured factors were: total length, medulla diameter, as well tonality pattern and type. For Intraspecific 530 hairs were assessed, taken from 53 organisms. In spite length diameter medulla, it possible to carry out successful identification organisms at specific level, using guide for terrestrial mammals –provided by Monroy-Vilchis Rubio-Rodriguez– parting hair; except Canis latrans Liomys irroratus. individual comparison 569 hairs, 14 species, examined. There some differences regarding coloration. only constant factor.
