Diversity patterns in the steppe of Argentinean Southern Patagonia: Environmental drivers and impact of grazing
(NOVA Science Publishers, 2013)The steppe ecosystem, mainly characterised by the presence of tussock, short grasses and shrubs, covers 85% of the total area in Santa Cruz Province and 25% in Tierra del Fuego Island. Most of the land in the Patagonian ... -
Flowering and seeding patterns in primary, secondary and silvopastoral managed Nothofagus antarctica forests in South Patagonia
(Taylor & Francis, 2010-06-11)The success ofthe reproductive process in trees depends on abiotic and biotic factors that determine the final outcome of natural regeneration. Silviculture alters biotic and abiotic factors and results in secondary forest ... -
Influencia de los daños por guanaco y abióticos sobre el crecimiento de la regeneración en bosques cosechados de lenga en Tierra del Fuego
(INTA - CIEFAP, 2016-11-09)Los bosques de lenga (Nothofagus pumilio) son cosechados mediante diferentes propuestas que abren el dosel permitiendo la instalación y el rápido desarrollo de la regeneración natural. En los primeros años pueden ser ... -
Landscape variables influence over active restoration strategies of Nothofagus forests degraded by invasive Castor canadensis in Tierra del Fuego
(MDPI, 2021-07-06)North American beavers (Castor canadensis) are responsible for the major changes in the Tierra del Fuego Archipelago, altering riparian forests for the long-term. Passive restoration of the areas affected was ineffective ... -
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 ... -
Precipitation is the key determinant of topsoil δ15N values in southern Patagonia’s semiarid rangelands
(American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America, 2022-02-11)Nitrogen (N) cycling in rangeland soils could potentially be controlled by water supply, stocking rates, or a range of other variables, such as ecosystem N stocks. To gauge the relative importance and elucidate possible ...
