Seeing the wood despite the trees: Exploring human disturbance impact on plant diversity, community structure, and standing biomass in fragmented high Andean forests. [PDF]

Ecol Evol, 2021
High Andean forests play a key role in providing ecosystem services for neighboring urban settlements. Here, we aimed to identify and understand the effects of anthropogenic perturbations on diversity, composition, and structure of plant communities, as well as aboveground biomass in high Andean forest remnants in the hinterland of Bogotá.

New records of tardigrades from Colombia (Guatavita, Cundinamarca Department)

Turkish Journal of Zoology, 2015
The water bears (Tardigrada) from Colombia are rather poorly known; thus, the aim of this research was to study the composition of tardigrade fauna inhabiting epiphytic and rock mosses in a high Andean forest in Guatavita. A 25-m2 plot was delimited and 6 randomly chosen trees with epiphytic mosses were sampled. Twelve samples of epiphytic mosses and 6
