Phenolic and volatile compounds in Quercus humboldtii Bonpl. wood: effect of toasting with respect to oaks traditionally used in cooperage [PDF]

Journal of the Science of Food and Agriculture, 2018
AbstractBACKGROUNDThe most frequent renewal of barrels of different origins and species is a current trend, but this demand does not match the current availability of wood. An alternative could be the use of Quercus humboldtii wood. However, there is little information about its composition.

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

Brazilian 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.

Post-fire responses of Quercus humboldtii mediated by some functional traits in the forests of the tropical Andes

Global Ecology and Conservation, 2020
The Andean forest is a high diversity ecosystem. These forests are negatively affected by anthropogenic pressures that have greatly increased wildfires. Wildfires may increase species susceptibility to other disturbances like insect pests. Little is known of these ecosystems, their responses to wildfires, or their interactions with other disturbances ...

Bee pollen as non-wood forest product in the eastern Andean highlands of Colombia

Colombia Forestal, 2013
The Andean forests of the Eastern Andean high-lands of Colombia have a high conservation priority given the vulnerable condition of species such as Quercus humboldtii (Fagaceae) that inhabit these ecosystems.

SOBREVIVENCIA Y CRECIMIENTO DE PLÁNTULAS DE TRES ESPECIES ARBÓREAS EN ÁREAS DE BOSQUE MONTANO ANDINO DEGRADADAS POR GANADERÍA EN COLOMBIA

Acta Biológica Colombiana, 2015
En la Región Lechera del centro de Antioquia el paisaje ha sido ampliamente transformado de bosques montanos a pastizales para pastoreo de ganado vacuno, siendo la restauración del paisaje en esta zona una acción primordial que debe ser incorporada en el

Effects of Light Intensity and Fertilization on the Growth of Andean Oak Seedlings at Nursery

Acta Biológica Colombiana, 2014
Quercus humboldtii is a native plant species of great importance in Colombia for use in reforestation and restoration of degraded Andean highlands. The species is highly threatened and it is necessary to establish programs of propagation and planting ...

Characterization of odour-active volatiles and sensory analyses of roasted oak (Quercus humboldtii Bonpl.) acorns, a coffee substitute

Revista Vitae, 2019
Antecedentes: las bellotas de roble se tuestan y se muelen para producir un polvo que se utiliza para preparar una bebida sustituta del café. Objetivos: Identificar los volátiles con olor activo del polvo derivado de las bellotas tostadas de Quercus humboldtii y realizar un análisis cuantitativo descriptivo (QDA) de su aspecto, olor y sabor.

Death caps (Amanita phalloides) frequently establish from sexual spores, but individuals can grow large and live for more than a decade in invaded forests

New Phytologist, Volume 242, Issue 4, Page 1753-1770, May 2024.
Summary Global change is reshaping Earth's biodiversity, but the changing distributions of nonpathogenic fungi remain largely undocumented, as do mechanisms enabling invasions. The ectomycorrhizal Amanita phalloides is native to Europe and invasive in North America.

Variable thermal plasticity of leaf functional traits in Andean tropical montane forests

Plant, Cell &Environment, Volume 47, Issue 3, Page 731-750, March 2024.
Abstract Tropical montane forests (TMFs) are biodiversity hotspots and provide vital ecosystem services, but they are disproportionately vulnerable to climate warming. In the Andes, cold‐affiliated species from high elevations are being displaced at the hot end of their thermal distributions by warm‐affiliated species migrating upwards from lower ...

Initial development of andean oak in response to management in nursery and at planting

Colombia Forestal, 2017
The establishment of plantations of Quercus humboldtii is required for the development of oak restoration programs and for commercial reforestation. In this work the effect of nursery management (relative lighting and fertilization), the characteristics ...
