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 ... -
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 ... -
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 ... -
Partición diferencial de nutrientes en arboles de Nothofagus antarctica creciendo en un gradiente de calidades de sitio en Patagonia Sur = Different nutrient allocation in Nothofagus antarctica trees growing over a site quality gradient in South Patagonia
(2013)Nothofagus antarctica (ñire) es una especie nativa caducifolia que crece al sur de Argentina y Chile. Estudiar la distribución de nutrientes en árboles es importante como base para el entendimiento de la dinámica de los ... -
