Abstract
As part of the wildlife monitoring activities of the El Cerrejón mine, the abundance of the Marmosa xerophila and Marmosa robinsoni species was evaluated in three different sectors (secondary dry forest of the La Estrella area, riparian forest operated on the Tabaco stream and bushes restored in the Rehabilitation – Spring area) by capture with Sherman traps. Capture success was considered as a descriptor of abundance. Marmosa xerophila was not very abundant (n = 2) and restricted to the area of restored shrubs, while the Marmosa robinsoni species was found with greater abundance (n = 21) with presence in all sampled areas. Marmosa robinsoni is considered to be an abundant species because it can occupy transformed habitats such as those present in the study area and that Marmosa xerophila is at a disadvantage due to habitat transformation.
