El deterioro del hábitat es una de las principales amenazas que afectan
negativamente a numerosas especies como los mamíferos medianos y grandes
que son sensibles a dichos cambios. En el presente trabajo se compara la
diversidad de mamíferos medianos y grandes en dos sitios con distinto grado
de conservación en La Venta, Juchitán, Oaxaca, México, para ello se
recorrieron cuatro transectos lineales de 4.5 km de longitud, dos en cada sitio
(conservado y perturbado) en donde se realizó la búsqueda de rastros. PALABRAS CLAVE: Mamíferos medianos y grandes, Diversidad, Conservación,
Perturbación, La Venta.
Habitat degradation is one of the main threats that negatively affect many
species like the medium and large mammals that are sensitive to such changes.
In this work we compare the biological diversity of medium and large mammals
in two sites with different degrees of conservation in La Venta, Juchitan,
Oaxaca, Mexico, for it toured four linear transects of 4.5 km of length, two in
each site (conserved and desturbed) that performed the search of signs of
tracks. 167 records of 18 species of medium and large mammals were obtained.
Seven species was found in some category of risk according to national and
international standards. KEY WORDS: Medium and large mammals, Diversity, Conservation, Disturbance,
La Venta.
