Seedling drought stress susceptibility in two deciduous Nothofagus species of NW Patagonia
Varela, Santiago Agustin; Gyenge, Javier Enrique; Fernandez, María Elena; Schlichter, Tomas Miguel (2010-06)The physiological capacities of seedlings to cope with drought may be subject to strong selective pressure in the context of future climate scenarios, threatening the regeneration and sustainability of forests. Characterization ... -
Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America
Gyenge, Javier; Fernandez, María Elena; Varela, Santiago Agustin (2012-12)Trees drought responses could be developed in the short- or in the long-term, aiming at sustaining carbon fixation and water use efficiency (WUE). The objective of this study was to examine short- and long-term adjustments ... -
Uso de compost en la producción de plantines de especies forestales
Varela, Santiago Agustin; Basil, Juan Gustavo (EEA Bariloche, INTA, 2011-03)La re-utilización de residuos de origen vegetal, animal y humano para recuperar o incrementar la fertilidad del suelo es una actividad que se conoce hace 2000 años. A lo largo de la historia de la agricultura, el hombre ... -
Uso del compost de biosólidos en la formulación de sustratos para la producción industrial de plantas de Nothofagus alpina = Evaluation of an alternative substrate and a differential nutritional dose on the production and final quality of seedlings of Nothofagus alpina in NW Patagonia
Varela, Santiago Agustin; Martinez, Abel Hector Maria (Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2013)Uno de los principales problemas para producir plantas forestales industrialmente es disponer de sustrato de buena calidad en cantidad suficiente. El objetivo de este estudio fue evaluar la factibilidad biológica del uso ... -
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 ...
