Anthropogenic Impacts Allowed for the Invasion of Understory Species, Affecting the Sustainability of Management Practices in Southern Patagonia
(MDPI, 2024-01-16)Forest management aims to preserve integrity and ecosystem resilience. Conservation and species invasion patterns must be determined in managed landscapes. The objectives of this study were to identify proxies that allowed ... -
Biophysical and socioeconomic factors influencing soil carbon stocks: a global assessment
(Springer, 2020-07-24)Soil is the most important terrestrial carbon (C) reservoir but is greatly impacted by land use change (LUC). Previous analyses of LUC impacts on soil C have focused on biophysical variables, leaving aside the influence ... -
Carbon footprint of lamb and Wool production at farm gate and the regional sale in southern Patagonia
(MDPI, 2020-04-11)Natural steppe grasslands are the principal food resource for sheep in the Patagonia region, reared for meat and wool. However, there is currently a concern about the relationship between ruminant livestock and climate ... -
Evaluación de indicadores de degradación y biomasa radical en mallines de una cuenca hídrica del sur de Santa Cruz
(Asociación Argentina de Ecología, 2020)Se planteó un estudio con el objetivo de analizar la asociación entre indicadores de deterioro del suelo y la vegetación, evaluar los cambios de esas variables entre sectores y condiciones de degradación, y monitorear ... -
Evaluación de la calidad nutricional en pasturas de gramíneas perennes relacionada con el estado fenológico y el ambiente en el Sur de Santa Cruz
(Universidad Nacional de la Patagonia Austral, 2022-09-30)En la Patagonia Austral la introducción de pasturas destinadas al uso estratégico en las áreas de mayor potencial representa una alternativa de manejo que permitiría aumentar la productividadde los sistemas ganaderos ... -
General destabilizing effects of eutrophication on grassland productivity at multiple spatial scales
(Springer Nature, 2020-10-23)Eutrophication is a widespread environmental change that usually reduces the stabilizing effect of plant diversity on productivity in local communities. Whether this effect is scale dependent remains to be elucidated. Here, ... -
Human appropriation of net primary production related to livestock provisioning ecosystem services in Southern Patagonia
(MDPI, 2022-06-22)Human appropriation of net primary productivity (HANPP) integrates ecological and socioeconomic perspectives on land use by quantifying the amount of net primary production (NPP) appropriated by society through biomass ... -
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 ... -
Neochelanops michaelseni (Pseudoscorpiones: Chernetidae) as potential bioindicator in managed and unmanaged Nothofagus forests of Tierra del Fuego
(BioOne, 2015-11-01)Bioindicators could act as early warning indicators of environmental changes, ecosystem stress or taxonomic diversity. Pseudoscorpions have rarely been used as bioindicators, due to lack of information about their ecology, ... -
Nitrogen but not phosphorus addition affects symbiotic N2 fixation by legumes in natural and semi‑natural grasslands located on four continents
(Springer Nature, 2022-09)The amount of nitrogen (N) derived from symbiotic N2 fixation by legumes in grasslands might be affected by anthropogenic N and phosphorus (P) inputs, but the underlying mechanisms are not known. Methods We evaluated ... -
Opposing community assembly patterns for dominant and non-dominant plant species in herbaceous ecosystems globally
(Wiley Ecology and evolution, 2021-11-22)Biotic and abiotic factors interact with dominant plants—the locally most frequent or with the largest coverage—and nondominant plants differently, partially because dominant plants modify the environment where nondominant ... -
Pasture and grassland productivity and foliar elongation of wheatgrass in Southern Patagonia = Productividad de pastura y pastizal y elongación foliar de agropiros en la Patagonia austral = Produtividade pastagem e pasto natural e alongamento foliar de agropyros no Sul da Patagônia
(INIA Uruguay y Facultad de Agronomía, Universidad de la República, 2023-07-28)The aim of this work was to show the relationship of the productivity of a pasture and grassland, the living and dead material, and the foliar elongation of wheatgrass with the soil moisture and the thermal sum in Southern ... -
Productividad y calidad nutricional de especies forrajeras típicas en mallines de la Patagonia Austral (Argentina) = Productivity and nutritional quality of typical forage species of Austral Patagonian Meadows (Argentina)
(Asociación Argentina de Producción Animal, 2017-12)Se planteó un estudio con el objetivo de evaluar la productividad y la calidad nutricional de las principales especies forrajeras nativas con aptitud de corte en mallines del SO de Santa Cruz. En este contexto, en clausuras ... -
Respuesta de la vegetación al manejo por corte en fajas en un arbustal de Mulguraea tridens en Patagonia sur
(2016-12)En Santa Cruz, aproximadamente 2.83 millones de hectáreas conforman el matorral de mata negra, una estepa arbustiva dominada por el arbusto Mulguraea tridens, donde la ganadería ovina extensiva es la principal actividad ... -
Restauración por recolonización de especies nativas en pasturas sembradas en ambientes semiáridos en Patagonia
(Facultad de Agronomía, Universidad Nacional de La Pampa, 2023-06-05)En Patagonia austral el sobrepastoreo provoca cambios irreversibles en los pastizales. La sucesión secundaria en pasturas comerciales podría promover parcialmente la recuperación de especies nativas. Se estudiaron lotes ... -
Sistemas silvopastoriles en bosques de Nothofagus antárctica: Revisión del conocimiento actual en Patagonia Sur, Argentina.
(INFOR (Chile), 2011-08)Los sistemas silvopastoriles, que combinan en una misma unidad de superficie árboles con pasturas o pastizales bajo pastoreo con ganado, son una alternativa productiva en la región Patagónica, y podrían constituir una ... -
Soil respiration in Patagonian semiarid grasslands under contrasting environmental and use conditions
