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 ... -
Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs
(Nature Research, 2019)Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental ... -
Leaf wettability, anatomy and ultra-structure of Nothofagus antarctica and N. betuloides grown under a CO2 enriched atmosphere
(Elsevier, 2023-01)Increasing CO2 air concentration may affect wettability, anatomy and ultra-structure of leaves of Patagonian forest species, evergreen and deciduous plants potentially responding differently to such CO2 increases. In this ... -
Linking changes in species composition and biomass in a globally distributed grassland experiment
(Wiley, 2022-11-24)Global change drivers, such as anthropogenic nutrient inputs, are increasing globally. Nutrient deposition simultaneously alters plant biodiversity, species composition and ecosystem processes like aboveground biomass ... -
Linking potential biodiversity and three ecosystem services in silvopastoral managed forest landscapes of Tierra del Fuego, Argentina
(Taylor & Francis, 2017-04)Several studies confirm that biodiversity loss endangers ecosystem services (ES) supply and human well-being. A better understanding of biodiversity–ES relationships and effects of biodiversity loss on ES supply is needed. ... -
Linking species distribution and territorial planning to the management of the endangered Gonopterodendron sarmientoi in native forests of the Chaco region, Argentina
(Elsevier, 2022-06-11)For management and conservation strategies in the long term is necessary to know the species distribution and main biophysical aspects that determine the structure and dynamics of the forest. The aim of this work was to ... -
Litter decomposition and nutrients dynamics in Nothofagus antarctica forests under silvopastoral use in Southern Patagonia.
(Springer, 2012-01-24)The role of environmental variables on litter decomposition and its nutrient release in Nothofagus antarctica forest in Patagonia is poorly understood. Moreover, in these forests under silvopastoral use there are few ... -
Litterfall and nutrients return in Nothofagus antarctica forests growing in a site quality gradient with different management uses in Southern Patagonia
(2015-01)We evaluated the annual litterfall and nutrients return in primary forests of Nothofagus antarctica growing at three different site classes (SC) (III, IV and V) and compared two of these forests with adjacent stands under ... -
Long-term monitoring of thinning for silvopastoral purposes in Nothofagus antarctica forests of Tierra del Fuego, Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2018)Aim of the study: To analyse the effectiveness of thinning on tree growth, forest structure and microclimatic variables along seven years after cuttings in a secondary Nothofagus antarctica forest in Southern Patagonia. Area ... -
Manejo de Bosques con Ganadería Integrada (MBGI) en Argentina
(INIA (Uruguay), 2022-01)La mayor parte de los bosques nativos en Argentina cuentan con ganadería. En este contexto, en 2015 se firma el Convenio Marco Interinstitucional entre los actuales Ministerios de Agroindustria y el de Ambiente y Desarrollo ... -
Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(2017-09-15)Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ... -
MASTREE+: Time-series of plant reproductive effort from six continents
(Wiley, 2022-04-01)Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such ... -
Microbial processing of plant remains is co‐limited by multiple nutrients in global grasslands
(Wiley, 2020-06)Microbial processing of aggregate‐unprotected organic matter inputs is key for soil fertility, long‐term ecosystem carbon and nutrient sequestration and sustainable agriculture. We investigated the effects of adding multiple ... -
Microclimatic conditions restrict the radial growth of Nothofagus antarctica regeneration based on the type of forest environment in Tierra del Fuego
(MDPI, 2023-05-27)Regeneration is crucial for forest continuity in natural and managed stands. Analyzing intra-annual dynamics can improve the understanding between growth and climate, identifying regeneration survival thresholds. The ... -
Microorganismos del suelo en bosques de ñire en Patagonia Sur: resultados preliminares.
(Instituto Forestal (INFOR), 2017-08)Nothofagus antarctica (ñire) es una especie nativa del bosque andino-patagónico que se extiende desde los 36º 30’ hasta los 56º 00’ LS. Es la segunda especie en importancia de la provincia de Santa Cruz, Argentina. En estos ... -
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 ... -
Mineral fertilization impacts microbial activity and endophytic fungi but not microbial biomass in semiarid grasslands
(Elsevier, 2024-01)Applications of mineral fertilizer to grasslands have become more frequent in recent decades to increase forage production. However, the impacts of mineral fertilizer on the soil microbiome is poorly understood in cold ... -
Mistletoes and epiphytic lichens contribute to litter input in Nothofagus antarctica forests
(Elsevier, 2015-10)Litter input is one of the key components that define nutrient cycling in forests and the majority of studies only consider the tree components of litterfall. However, epiphytic species can play a crucial role in litter ... -
Modeling of potential habitat suitability of Hippocamelus bisulcus: effectiveness of a protected areas network in Southern Patagonia
(Springer, 2017)Introduction Huemul (Hippocamelus bisulcus Molina) is the most threatened flag species of Southern Patagonia, where conservation efforts were not effective to avoid the retraction of its distribution area. Habitat quality ... -
