Changes in soil organic matter associated with afforestation affect erosion processes: the case of erodible volcanic soils from Patagonia
La Manna, Ludmila; Tarabini, Manuela; Gomez, Federico Antonio; Rostagno, Cesar Mario (Elsevier, 2021-06-17)Large areas of the Patagonian Andean Region with high potential for planting fast-growing exotic conifers, based on the volcanic nature of its soils, are affected by erosion processes. This study aimed to analyse the effects ... -
Mapping soil organic carbon content in Patagonian forests based on climate, topography and vegetation metrics from satellite imagery
Martínez Pastur, Guillermo José; Aravena Acuña, Marie Claire; Silveira, Eduarda M.O.; Von Müller, Axel; La Manna, Ludmila; González Polo, Marina; Chaves, Jimena Elizabeth; Cellini, Juan Manuel; Lencinas, María Vanessa; Radeloff, Volker C.; Pidgeon, Anna Michle; Peri, Pablo Luis (Multidisciplinary Digital Publishing Institute (MDPI), 2022-11-11)Soil organic carbon (SOC) content supports several ecosystem services. Quantifying SOC requires: (i) accurate C estimates of forest components, and (ii) soil estimates. However, SOC is difficult to measure, so predictive ... -
Phytophthora austrocedri in Argentina and co-Inhabiting phytophthoras: roles of anthropogenic and abiotic factors in species distribution and diversity
Vélez, María Laura; La Manna, Ludmila; Tarabini, Manuela; Gomez, Federico Antonio; Elliott, Matt; Hedley, Pete E.; Cock, Peter; Greslebin, Alina (MDPI, 2020-11-20)This work reports the first survey of Phytophthora diversity in the forests soils of Andean Patagonia. It also discusses the role of anthropogenic impact on Phytophthora distribution inferred from the findings on Phytophthora ... -
Resilient andisols under silvopastoral systems
Gomez, Federico Antonio; Von Müller, Axel; Tarabini, Manuela; La Manna, Ludmila (Elsevier, 2022-03-20)Livestock can affect physical and chemical soil properties, depending on both stocking rates, and intrinsic soil properties. This study aimed to analyze changes in physicochemical properties in volcanic soils under ... -
Role of abiotic factors in nothofagus pumilio forest mortality: the sensitivity of ecotones
Tarabini, Manuela; Gomez, Federico Antonio; Calderón, Miguel Ángel; La Manna, Ludmila (Elsevier, 2021-04-24)The world's forests are being affected by a changing climate. Recently, patches of dead trees have been found in forests of the Patagonian endemic species Nothofagus pumilio, which could not be related to insects or ...
