MEDINA TORRES, Salvador Martín et al. Factores que influyen en el uso del hábitat por el venado cola blanca (Odocoileus virginianus couesi) en la Sierra del Laurel, Aguascalientes, México. Acta Zool. Mex [online]. 2008, vol.24, n.3, pp.191-212. ISSN 2448-8445.

Habitat use by the Coues white tailed deer (Odocoileus virginianus couesi) was documented during the dry season of 2006, in the Sierra del Laurel, Aguascalientes, Mexico. Based on logistic regression analyses, the objective of this study was to determine which floristic-structural and topographical features influence the probability of habitat use by the Coues deer. Vegetation, slope, altitude and distance to water were significant (p < 0.01) in the probability of habitat use. The thresholds for slope, altitude and distance were estimated for a high probability of use p (y≥0.5) and varied due to vegetation type. Sites on subtropical vegetation with 50 trees of Ipomoea murucoides Roem. & Schult by hectare and 350 shrubs of Eysenhardtia polystachya Ortega Sarg., and mean height of the shrub layer over the 2.0 meters, had a probability of use greater than 50 percent. However this vegetation type is scarce and threatened by agricultural development in the Sierra del Laurel. The results of this research clearly point out the need to promote management and conservation strategies of this type of vegetation since it is the preferred habitat of the Coues deer, which in turn should be considered as an asset by the state holders and an option to derive additional income from hunting fees and other economic activities pertaining to a multiple use of the land.
