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 ... -
Modeling soil nitrogen content in South Patagonia across a climate gradient, vegetation type, and grazing
(MDPI, 2019-05)Soil total nitrogen (N) stock in rangelands, shrublands, and forests support key ecological functions such as the capacity of the land to sustain plant and animal productivity and ecosystem services. The objective of this ... -
Modelling soil carbon content in south Patagonia and evaluating changes according to climate, vegetation, desertification and grazing
(2018)In Southern Patagonia, a long-term monitoring network has been established to assess bio-indicators as an early warning of environmental changes due to climate change and human activities. Soil organic carbon (SOC) content ... -
Modelo de simulación de producción de materia seca y concentración de proteína bruta de gramíneas creciendo en bosques de Nothofagus antarctica (G. Forster) Oerst. bajo uso silvopastoril
(2014)Nothofagus antarctica (ñire) ocupa una importante fracción de los bosques de la Patagonia Austral y suele ser usado en sistemas silvopastoriles. Se carece, sin embargo de información que permita hacer un uso óptimo y ... -
Modelos forzados y no forzados para el cálculo del índice de sitio en bosques de Nothofagus antarctica en Patagonia Sur = Constrained and non-constrained models for site index estimation in Nothofagus antarcticaforests of South Patagonia
(Facultad de Ciencias Forestales y Recursos Naturales, Universidad Austral de Chile, 2011)El potencial de producción de un rodal puede definirse a través de la calidad de sitio. Una forma de medir dicha calidad es a través de ecuaciones de índice de sitio, existiendo distintos tipos de ecuaciones (forzadas y ... -
