Defoliation frequency affects morphophysiological traits in the bunchgrass Poa ligularis = La frecuencia de defoliación afecta las carcacterísticas morfofisiológicas en la gramínea perenne Poa ligularis
(Fundacion Romulo Raggio, 2010-11)Poa ligularis is an important forage in Patagonian rangelands. Populations of this perennial bunchgrass have been severely affected by overgrazing. We propose that increased defoliation frequencies will decrease (1) aerial- ... -
Evidence on the response of Patagonian forage grasses to the mulching effect of recent tephra deposits in Argentina
(Taylor & Francis, 2017-08-31)In Patagonia, arid and semiarid lands are being affected both by inappropriate management practices, which are leading to degradation, and by volcanic activity, whose effects are still unclear. This study aimed to test ... -
Relationship between NDVI of Patches and Cover Area of Grasses, Shrubs and Bare Soil Components of a Semi-Arid Steppe from North-West Patagonia, Argentina
(MDPI, 2023-02)Distinguishing the contributions of different vegetation cover such as shrubs and grasses components into the primary production in arid and semi-arid rangelands is a key step to understanding changes at a landscape scale. ... -
Seasonal diet of Lama guanicoe (Camelidae: Artiodactyla) in a heterogeneous landscape of South Patagonia = Dieta estacional de Lama guanicoe (Camelidae: Artiodactyla) en un paisaje heterogéneo de Patagonia Sur
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2013)Large diversity of habitat types, plant species assemblages, and silvopastoral activities in Nothofagus spp. forests condition the food availability for native herbivores. This work evaluates the seasonal diet of Lama ... -
The sign and magnitude of tree–grass interaction along a global environmental gradient
(2016-12)Aim: The ecological literature posits that positive interactions are preponderant in stressful environments; however, the net balance between positive and negative interactions at the community level is still under debate. ...
