Madre Monte Natural Conservation Area in the Colombian Andes as Model for Preservation of Fungi in Quercus humboldtii Forests [PDF]

open access: diamondBrazilian Archives of Biology and Technology, 2021
Abstract Few conservation studies have been done with Agaricales fungi (mushrooms) of the Andes and conservation areas created in many countries have no priorities in protecting fungi. Small areas can be also very important to preserve rare and unknown fungi species, but evaluations are still needed.

Mating Patterns of a Subdivided Population of the Andean Oak (Quercus humboldtii Bonpl., Fagaceae) [PDF]

open access: bronzeJournal of Heredity, 2005
Mating patterns play a critical role in the maintenance of genetic variation. We analyzed the mating system in a recently fragmented population of the Andean oak (Quercus humboldtii) using four microsatellite loci. Five fragments in northeastern Colombia, South America, were selected consisting of 30.4 trees on average.
