Sex-related climate sensitivity of Araucaria araucana Patagonian forest-steppe ecotone
(Elsevier Science, 2016-02)
Dioecious species offers the possibility to discern plant development in relation to sex. However, there is little information of the incidence of sex on tree-growth sensitivity to seasonal variations in climate. In this ...
Migración asistida de Araucaria araucana
(FAO, MINAGRI, 2021)
Con el presente trabajo se busca proporcionar a los silvicultores y a las personas que trabajan en manejo y conservación de recursos genéticos un marco de conocimientos básicos sobre los efectos actuales y potenciales del ...
Climatic cues for secondary growth and cone production are sex-dependent in the long-lived dioecious conifer Araucaria araucana
(Elsevier B.V., 2019)
Trees’ growth responses to climate may depend on tree age and site conditions. In dioecious species, sex adds an extra level of complexity due to differential reproductive effort between the sexes and potentially sex-related ...
Ecología de vertebrados que anidan en cavidades de árboles en bosques de Pino Paraná (Araucaria angustifolia) y Pehuén (Araucaria araucana): uso de árboles-nido y redes interespecíficas
(2016)
Comparar la ecología de fauna de localidades distantes puede ayudar en la búsqueda de patrones generales sobre cómo las especies seleccionan los recursos y cómo las interacciones interespecíficas estructuran a las comunidades. ...
Morphology and tructure of the pollen cone and pollen grain of the Araucaria species from Argentina
(Instituto de Histología y Embriología, 2008-12)
The pollen cone and the pollen grain of the two Argentinean species of Araucaria are described with LM, SEM and TEM. Primordia of pollen cones are formed in April and May and reach maturity by mid-October in A. angustifolia ...
Efecto del clima en los anillos de crecimiento de Araucaria araucana en el norte de la Patagonia Argentina
(Asociación Española de Ecología Terrestre, 2014-12)
Araucaria araucana (Molina) K. Koch (Pehuén), es una conífera dioica, endémica de los bosques templados del centro-sur de Argentina y Chile, distribuida entre 900 y 1800 m de altitud y entre los 37° 20’ y 40° 20’ de latitud ...
Pine invasion impacts on plant diversity in Patagonia: invader size and invaded habitat matter
(Springer, 2016-12)
Conifers, which are widely planted as fast growing tree crops, are invading forested and treeless environments across the globe, causing importantchanges in biodiversity. However, how small-scale impacts on plant diversity ...
Evaluation of the health status of Araucaria araucana trees using hyperspectral images
(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2018)
The Araucaria araucana is an endemic species from Chile and Argentina, which has a high biological, scientific and cultural value and since 2016 has shown a severe affection of leaf damage in some individuals, causing in ...
Aboveground tree biomass of Araucaria araucana in southern Chile: measurements and multi-objective optimization of biomass models
(SISEF-Soc Italiana Selvicoltura Ecol Forestale, 2021)
Estimating carbon stocks in wooded systems is crucial to quantify national
greenhouse gas balance estimates. However, inaccurate estimates are likely
due to the divergent architecture of many species. The monkey puzzle ...
