Caracterización de la situación sanitaria de un rodal de Nothofagus pumilio afectado por notophorina sp.
Tarabini, Manuela; Gomez, Federico Antonio; La Manna, Ludmila; Gomez, Cecilia (Asociación Argentina de Ecología, 2023-12)En un bosque de lenga (Nothofagus pumilio) en el norte de Chubut, detectamos un rodal afectado por Notophorina sp. (Hemiptera, Psyllidae) con sintomatología foliar destacada. Asumimos que se trata de un pico poblacional ... -
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 ... -
Effects of livestock on the quality of the riparian forest, soil and water in Nothofagus silvopastoral systems
Gomez, Federico Antonio; Tarabini, Manuela Mabel; La Manna, Ludmila Andrea; Von Müller, Axel (Springer Nature, 2024-04-03)Controversial aspects of production vs.conservation were profusely discussed globally by considering climate change and its impact on ecosystem services provision. However, previous meticulous livestock planning and short ... -
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.

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 ...
