SPECIES RICHNESS AND INDICES OF ABUNDANCE OF MEDIUM-SIZED MAMMALS IN ANDEAN FOREST AND REFORESTATIONS WITH ANDEAN ALDER: A PRELIMINARY ANALYSIS
We studied the species richness and two indices of abundance of medium-sized<br />mammals in areas with Andean forest and Andean alder (Alnus acuminata)<br />reforestations in a reserve at the Central Andes of Colombia. Since reforested areas<br />have a less complex habitat struct...

| description | We studied the species richness and two indices of abundance of medium-sized<br />mammals in areas with Andean forest and Andean alder (Alnus acuminata)<br />reforestations in a reserve at the Central Andes of Colombia. Since reforested areas<br />have a less complex habitat structure and lower plant diversity than native forests, we<br />predicted that they have lower richness of mammals than areas with Andean forest.<br />We obtained the indices of abundance from direct contacts in transects and from the<br />use of track stations. Our results suggest that, indeed, areas with Andean forest had<br />a higher richness of mammals than reforestations, but this pattern may be modified<br />by anthropogenic factors. We found no differences between the indices of abundance<br />of the squirrel, Sciurus granatensis, in the two forest types. In contrast, the coatis<br />were recorded more frequently in the reforestations than in areas with Andean forest<br />at the reserve. |
