Afforestations and wetlands, are they a good combination? Study of water fluxes in two cases of Patagonian wetlands
Weigandt, Mariana Noemi; Gyenge, Javier; Fernandez, María Elena; Varela, Santiago Agustin; Schlichter, Tomas Miguel (Wiley, 2015-04)Wetlands are ecosystems that play a key role in maintaining biodiversity and associated economies (e.g. agriculture and livestock) because they are reservoirs of water and carbon. Globally, these environments have been ... -
Does competition management improve the ecophysiological response to water shortage of mixed woodland species of North Patagonia?
Varela, Santiago Agustin; Diez, Juan Pablo; Letourneau, Federico Jorge; Bianchi, Emilio; Weigandt, Mariana Noemi; Porté, A.J.; Sergent, Anne Sophie; Nacif, Marcos E.; Garibaldi, Lucas Alejandro; Fernandez, María Elena (Elsevier, 2023-08)Globally, the increasing forests vulnerability and drought-induced forest mortality events, extended to a larger scale, may have the potential to rapidly alter forest functioning and the provision of ecosystem services. ... -
Growth response of Pinus contorta to the synergy of stress factors: successive extreme drought events and a population outbreak of Sirex noctilio in NW Patagonia
Weigandt, Mariana Noemi; Villacide, Jose Maria; Bianchi, Emilio; Varela, Santiago Agustin (Springer, 2022-02)The synergy of biotic and abiotic stress factors influences the response in growth, resistance, recovery and resilience of forest systems. This study used a dendrochronological approach to analyze the annual radial increase ... -
Is forage productivity of meadows influenced by the afforestation of upstream hillsides? A study in NW Patagonia
Weigandt, Mariana Noemi; Gyenge, Javier Enrique; Fernandez, María Elena; Varela, Santiago Agustin; Schlichter, Tomas Miguel (2011)Meadows are important reserves of water, with a key role in the maintenance of the biodiversity and productivity of ecosystems. In Patagonia, Argentina, afforestation with fast-growing exotic conifers has slowly but ... -
Is forage productivity of meadows influenced by the afforestation of upstream hillsides? A study in NW Patagonia = Afecta la presencia de forestaciones ubicadas en las laderas aguas arriba de mallines su productividad forrajera? Un estudio en el Noroeste Patagónico
Weigandt, Mariana Noemi; Gyenge, Javier; Fernandez, María Elena; Varela, Santiago Agustin; Schlichter, Tomas Miguel (Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), (España), 2011-04-13)Meadows are important reserves of water, with a key role in the maintenance of the biodiversity and productivity of ecosystems. In Patagonia, Argentina, afforestation with fast-growing exotic conifers has slowly but ... -
Physiological status of conifer seedlings treated with radiation, drought and frost stress mitigation techniques: a laboratory assessment
Varela, Santiago Agustin; Weigandt, Mariana Noemi; Willems, Priscila Mabel; Bianchi, Emilio; Diez, Juan Pablo; Gyenge, Javier Enrique (2016)En la región oriental del noroeste de la Patagonia, se levanta del rápido crecimiento de coníferas exóticas Pinus ponderosa (pino ponderosa) y Pseudotsuga menziesii (Abeto de Douglas) se están estableciendo en lugares que ... -
Uso del agua y productividad de los bosques nativos e implantados en el NO de la Patagonia : aproximaciones desde la ecohidrología y la ecofisiología
Gyenge, Javier Enrique; Fernandez, María Elena; Licata, Julián Andrés; Weigandt, Mariana Noemi; Bond, Barbara J.; Schlichter, Tomas Miguel (2011-12)Existe preocupación por el posible uso excesivo de agua de las forestaciones con especies exóticas de rápido crecimiento en comparación con las especies nativas a las cuales reemplazan en la región NO de la Patagonia. ...
