Stand development stages and recruitment patterns influence fine-scale spatial genetic structure in two Patagonian Nothofagus species
Sola, Georgina Giselle; Marchelli, Paula; Gallo, Leonardo Ariel; Chauchard, Luis Mario; El Mujtar, Veronica Andrea (Springer, 2022-05)Key message: Nothofagus alpina (Poepp. et Endl.) Oerst. and Nothofagus obliqua (Mirb.) Oerst forests have strong fine-scale spatial genetic structures. The intensity of genetic structure patterns differed according to ... -
Staying close: short local dispersal distances on a managed forest of two Patagonian Nothofagus species
Sola, Georgina Giselle; El Mujtar, Veronica Andrea; Gallo, Leonardo Ariel; Vendramin, Giovanni Giuseppe; Marchelli, Paula (Oxford University Press, 2020-05)Understanding the impact of management on the dispersal potential of forest tree species is pivotal in the context of global change, given the implications of gene flow on species evolution. We aimed to determine the effect ... -
Supplementary data to "Genetic variation of leaf pigment content in a southern beech" ( Trees, structure and function 36 : 1823–1836, 2022) [Conjunto de datos]
Arias Rios, Jorge Andrés; El Mujtar, Veronica Andrea; Pastorino, Mario Juan; Marchelli, Paula (2022)Datos primarios de concentraciones de pigmentos determinados para 400 individuos de raulí en dos años sucesivos (2018-2019) en el ensayo de ambiente común y la referencia a su cuenca lacustre, población y familia y también ... -
Temperate Subantarctic Forests: A Huge Natural Laboratory
Marchelli, Paula; Pastorino, Mario Juan; Gallo, Leonardo Ariel (Springer, 2021)In the southern tip of South America, temperate subantarctic forests develop on both sides of the Andes mountain range. Known in Argentina as Andean-Patagonian forests, these ecosystems cover a narrow but long latitudinal ... -
Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
Sekely, Jill; Marchelli, Paula; Arana, María Veronica; Dauphin, Benjamin; Mattera, Maria Gabriela; Pastorino, Mario Juan; Scotti, Ivan; Soliani, Carolina; Heer, Katrin; Opgenoorth, Lars (BioRxiv, 2023-04-29)Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ... -
The effects of Quaternary glaciations in Patagonia as evidenced by chloroplast DNA phylogeography of Southern beech Nothofagus obliqua
Azpilicueta, Maria Marta; Marchelli, Paula; Gallo, Leonardo Ariel (Springer, 2009-03)Climatic oscillations during the Quaternary strongly affected the distribution of warm-temperate tree species, which experienced local restrictions into ice-free areas and posterior expansions. To evaluate the impact of ... -
Transcriptomic responses to drought stress in the Patagonian southern beech Nothofagus alpina
Lopez Laphitz, Rita Maria; Arana, María Veronica; Varela, Santiago Agustin; Becker, Leandro Aníbal; Soliani, Carolina; Azpilicueta, Maria Marta; Marchelli, Paula; Bellora, Nicolás (Springer Open, 2024-05)Background: Deciphering the genetic architecture of drought tolerance could allow the candidate genes identification responding to water stress. In the Andean Patagonian forest, the genus Nothofagus represents an ecologically ... -
Understanding introduction history: Genetic structure and diversity of the edible ectomycorrhizal fungus, Suillus luteus, in Patagonia (Argentina)
Pildain, Maria Belen; Marchelli, Paula; Azpilicueta, Maria Marta; Starik, Cristian; Barroetaveña, Carolina (Taylor & Francis, 2021-06)Suillus luteus is a common ectomycorrhizal (EM) fungus associated with several Pinus species. It is distributed throughout the Northern Hemisphere and has been introduced into South America and New Zealand. We examined the ... -
Variabilidad genética en Raulí (Nothofagus nervosa (Phil.) Dim. et Mil. su relación con procesos evolutivos y su importancia en la conservación y utilización de sus recursos genéticos
Marchelli, Paula (Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, 2001-06)El Raulí, Nothofagus nervosa (Phil.) Dim. et Mil., es una de las especies arbóreas de los bosques Andino-patagónicos de importancia ecológica y económica. Su distribución en Argentina es muy reducida y relativamente ... -
Variación genética y ecofisiológica de Festuca pallescens (St. Yves) en relación a un gradiente pluviométrico en Patagonia Norte
Lopez, Aldana (2018)Los ambientes heterogéneos presentan características climáticas, topográficas y edáficas que varían en tiempo y espacio favoreciendo la formación de gradientes clinales. Estos generan presiones de selección diferenciales ... -
Water-mediated changes in plant–plant and biological soil crust–plant interactions in a temperate forest ecosystem
Pissolito, Clara; Garibotti, Irene Adriana; Varela, Santiago Agustin; Arana, María Veronica; Gonzalez Polo, Marina; Marchelli, Paula; Bruzzone, Octavio Augusto (Copernicus Publications, 2019-04-09)In the quest to understand how biotic interactions respond to climate change, one area that remains poorly explored is how interactions involving organisms other than vascular plants will respond. However the interactions ... -
Yeast and yeast‐like fungi associated with dry indehiscent fruits of Nothofagus nervosa in Patagonia, Argentina
Fernandez, Natalia Verónica; Mestre, María Cecilia; Marchelli, Paula; Fontenla, Sonia Beatriz (Oxford Academic Press, 2012-04)Nothofagus nervosa (Raulí) is a native tree species that yields valuable timber. It was overexploited in the past and is currently included in domestication and conservation programs. Several research programs have focused ... -
