Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Elsevier, 2010-01)We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ... -
Cartografía de un nuevo Modelo de Estados y Transiciones de la Estepa Magallánica Seca en la Patagonia argentina
(Asociación Argentina de Ecología, 2021-08)Analizamos 103 censos de vegetación de la Estepa Magallánica Seca, un área de 12000 km2 de estepas graminosas semiáridas en el SE de la Patagonia. Los objetivos del presente trabajo fueron ampliar el relevamiento de ... -
The effects of land management (grazing intensity) vs. the effects of topography, soil properties, vegetation type, and climate on soil carbon concentration in Southern Patagonia
(Elsevier, 2016-11)Grazing is an economically important activity in Southern Patagonia’s steppe and woodland ecosystems. In the past, emphasis has been on maximizing the provisioning capacity of these ecosystems with little concern for the ... -
Improving the knowledge of plant potential biodiversity-ecosystem services links using maps at the regional level in Southern Patagonia.
(Springer, 2021-07-22)Background: Biodiversity supports multiple ecosystem services, whereas species loss endangers the provision of many services and affects ecosystem resilience and resistance capacity. The increase of remote sensing techniques ... -
Mineral elements in grasses growing in contrasting environmental conditions in southern Patagonia
(2016)The importance of grasses and graminoids for sheep nutrition in Argentinean Patagonia is widely recognized. Focusing on sheep nutrition, we assessed the concentration of mineral elements in grasses growing in three ecological ... -
Photosynthetic response to different light intensities, water status and leaf age of two Berberis species (Berberidaceae) of Patagonia steppe, Argentina.
(Elsevier, 2011-11)Net photosynthetic rate (A) and stomatal conductance (gs) from leaves of Berberis buxifolia and Berberis heterophylla saplings were measured under different conditions of radiation and water availability and for leaves of ... -
Photosynthetic response to water stress of the main grass species of southern patagonian steppe, Argentina
(Elsevier, 2024-10)Comparative studies of basic physiological performance are needed to give insight of how grass species survive and grow under current and more severe drought predicted in the framework of climate change in arid steppe ... -
Relación entre índices de sequía usando datos meteorológicos y satelitales, en la estepa magallánica seca (Patagonia)
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-04)Los efectos de la sequía impactan en el sector productivo de las distintas regiones, incidiendo en la vegetación, la disponibilidad de agua y las consecuencias que ello ocasiona, por lo que resulta de interés el estudio ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
(Elsevier, 2015-08)Grasslands comprise 85% of Southern Patagonia land area and play a critical role in the global carbon cycle. We evaluated seasonal dynamics to identify differences in soil respiration rates between contrasting grasslands ...
