EFECTO DE BORDE EN LA DIVERSIDAD Y COLONIZACIÓN DE ECTOMICORRIZAS DE Quercus humboldtii (FAGACEAE) EN ARCABUCO- BOYACÁ-COLOMBIA

Acta Biológica Colombiana, 2022
Los robledales en Colombia están dominados por la especie Quercus humboldtii Bonpl. Esta especie se encuentra en categoría de vulnerable debido a la deforestación para generar cultivos, zonas ganaderas y plantaciones de especies exóticas, ocasionando la

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range. [PDF]

New Phytol
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

The Mechanisms Through Which Fire Drives Population Change in Terrestrial Biota. [PDF]

Glob Chang Biol
Understanding the mechanisms through which fire influences populations is necessary to protect species from fire regime change. We develop a cross‐taxa framework that identifies mechanisms through which fire regimes influence terrestrial species populations, including for amphibians, birds, fungi, insects, mammals, plants, and reptiles.

Nuclear and chloroplast DNA phylogeography reveals high genetic diversity and postglacial range expansion in Quercus mexicana

American Journal of Botany, Volume 110, Issue 12, December 2023., 2023
Abstract Premise Phylogeographical studies are fundamental for understanding factors that influence the spatial distribution of genetic lineages within species. Population expansions and contractions, distribution shifts, and climate changes are among the most important factors shaping the genetic compositions of populations.

Demographic and spatially explicit landscape genomic analyses in a tropical oak reveal the impacts of late Quaternary climate change on Andean montane forests

Molecular Ecology, Volume 32, Issue 12, Page 3182-3199, June 2023., 2023
Abstract The tropical Andes are one of the most important biodiversity hotspots on Earth, yet our understanding of how their biotas have responded to Quaternary climatic oscillations is extraordinarily limited and the alternative models proposed to explain their demographic dynamics have been seldom formally evaluated. Here, we test the hypothesis that

Role of litter turnover in soil quality in tropical degraded lands of Colombia. [PDF]

ScientificWorldJournal, 2014
Land degradation is the result of soil mismanagement that reduces soil productivity and environmental services. An alternative to improve degraded soils through reactivation of biogeochemical nutrient cycles (via litter production and decomposition) is the establishment of active restoration models using new forestry plantations, agroforestry, and ...

[Vertical stratification of epiphytic bryophytes found on Quercus humboldtii (Fagaceae) from boyacá, Colombia].

Revista de biologia tropical, 2014
Los bosques de roble representan una formación vegetal de importancia ecológica, debido a la cantidad de plantas epífitas que pueden llegar a albergar; estas han sido muy poco estudiadas en Colombia, especialmente las no vasculares. Para el país, uno de los robledales de mayor extensión es el Parque Natural Municipal “Robledaes de Tipacoque” (PNMRT ...
