Structure and Composition of Colombian Montane Oak Forests

Plastome of Quercus xanthoclada and comparison of genomic diversity amongst selected Quercus species using genome skimming

“…In the family, Quercus is the largest genus, with ±500–550 accepted species of broad-leaved, deciduous or evergreen trees and shrubs (Denk et al 2017; Nixon 2006). Although best known from Europe and North America, it extends well into Central and South America, as well as the Asian tropical regions (Indo-China, Malesia) with large numbers of species (Soepadmo and Steenis 1972; Pulido et al 2006; Phengklai 2008). South America appears to one of the most recent areas to be colonized by the genus, with Q. humboldtii occurring as far south as Colombia (Pulido et al 2006).…”

South America appears to one of the most recent areas to be colonized by the genus, with Q. humboldtii occurring as far south as Colombia (Pulido et al 2006). Until recently, the genus was divided in five subgenera and sections, based on molecular (Oh and Manos 2008), pollen morphology (Denk and Grimm 2009), morphological (Luo and Zhou 2002) and historical treatments (Camus 1936–1954).…”

Conservación y uso sostenible de los bosques de roble en el corredor de conservación guantiva - la Rusia - Iguaque, departamentos de santander y Boyacá, Colombia

“…Las condiciones de humedad y sombra generadas por las densas copas de estos bosques permiten la presencia de un gran número de especies de brióitos, líquenes, bromelias, orquídeas y helechos. De acuerdo con Pulido et al (2006) al interior de los robledales existe una rica biodiversidad de lora que supera las 550 especies de plantas vasculares, entre las cuales sobresalen familias como Melastomataceae, Rubiaceae, Clusiaceae, Lauraceae, Orchidaceae; además esta gran diversidad de plantas que se encuentran en los bosques de roble mantiene una abundante oferta alimenticia de frutos y semillas para aves y mamíferos. Los estudios ecológicos de robledales en Colombia realizados por Rangel & Lozano (1989), Rangel et al (2005), Rangel et al (2008), Rangel et al (2009) y Van der Hammen (2008) y los realizados en el corredor de conservación por Barrera & Díaz (2006), Galindo et al (2006), Devia & Arenas (1997), Van der Hammen et al (2008), Avella et al (2009) y Ángel & Avila (2009), han podido identiicar varios tipos de robledales los cuales tienen considerables diferencias en términos de estructura y composición lorística.…”

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

“…(1805) (section Lobatae )—the only South American oak and the southernmost representative of the genus—is a characteristic species of the montane forest from the Colombian Cordilleras (Hooghiemstra et al, 2022; Torres et al, 2013). It occurs in the Lower and Upper Montane Forest belts (780–3600 m; Hooghiemstra et al, 2022; Zorrilla‐Azcué et al, 2021), occupying a wide spectrum of climatological conditions and forming multiple phytosociological associations (Hooghiemstra et al, 2022; Hooghiemstra & Flantua, 2019; Pulido et al, 2006; Rangel & Avella, 2011). The broad ecological range of the species has been hypothesized to facilitate its southward expansion through the Panamanian Isthmus and the colonization of the three northern Andean Cordilleras (Hooghiemstra et al, 2022; Rangel & Avella, 2011).…”
