This study reports movement patterns and home range estimates of an Andean fox ( Lycalopex culpaeus ) in Cotopaxi National Park in Ecuador, representing the first GPS-tagging of the species. The GPS functioned well during the 197-day tracking period. Home range sizes ranged between 4.9 and 8.1 km ² , depending on the estimation method. Movement spe...

Glyphonycteris is a poorly known genus of bats that inhabit lowlands and forested mountains of Central and South America. This genus comprises three nominal species, with G. sylvestris being the most widely distributed species in South America. The karyological data previously available for this genus are restricted to those resulting from conventi...

We present a novel report of Tapirus pinchaque, widening its range of distribution to southwestern Ecuador.

Animals moving through landscapes need to strike a balance between finding sufficient resources to grow and reproduce while minimizing encounters with predators. Because encounter rates are determined by the average distance over which directed motion persists, this trade-off should be apparent in individuals’ movement. Using GPS data from 1,396 in...

Here we report movement patterns and home range estimates of an Andean fox ( Lycalopex culpaeus ) in Cotopaxi National Park, representing the first GPS-tagging of the species. The GPS functioned well during the 197-day tracking period. Home range sizes ranged between 4.9 - 8.1 km ² , depending on the estimation method. Movement speeds averaged 0.17...
