Allometric relations for biomass partitioning of Nothofagus antarctica trees of different crown classes over a site quality gradient
(Elsevier, 2010-03)Data on tree biomass are essential for understanding the forest carbon cycle and plant adaptations to the environment. We determined biomass accumulation and allometric relationships in the partitioning of biomass between ... -
BAAD: A biomass and allometry database for woody plants.
(Ecological Society of America, 2015-05-01)Understanding how plants are constructed—i.e., how key size dimensions and the amount of mass invested in different tissues varies among individuals—is essential for modeling plant growth, carbon stocks, and energy fluxes ... -
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Elsevier, 2010-01)We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ... -
Changes in nutrient and fibre tissue contents in Nothofagus pumilio trees growing at site quality and crown class gradients
(Elsevier, 2022-02-01)Estimation of biomass and nutrient contents in tree components are essential for evaluating the impact of harvesting on carbon fixation capacity, bio-element recycling, and long-term effect on the balance that influence ... -
Desarrollo de un modelo para asignación variable de carga animal (MAVC) en Patagonia Sur
(Fundación CIPAV, 2016-11)El ajuste de la carga animal es un aspecto clave en el manejo del pastoreo extensivo y en Santa Cruz, Argentina se realiza tradicionalmente utilizando una asignación fija de forraje (AFF) por animal, indistintamente si un ... -
Environmental heterogeneity modulates the effect of plant diversity on the spatial variability of grassland biomass
(Springer Nature, 2023-03-31)Plant productivity varies due to environmental heterogeneity, and theory suggests that plant diversity can reduce this variation. While there is strong evidence of diversity effects on temporal variability of productivity, ... -
Establecimiento y producción de forraje de cereales de invierno en la patagonia austral
(Asociación Argentina de Producción Animal, 2020-12)Se realizó un ensayo con el objetivo de evaluar el establecimiento y la producción de forraje para henificación de una variedad y líneas de triticale (X Triticosecale Wittmack), variedades de trigo pan (Triticum aestivum ... -
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 ... -
Foliar N⁄ P ratio and nutrient limitation to vegetation growth on Keerqin sandy grassland of North-east China.
(Wiley, 2011-02-01)To examine whether the critical leaf N ⁄ P ratios (of 14, 16) are valid to test nutrient limitation in the context of semi-arid sandy grasslands, an experiment was conducted on a Keerqin sandy grassland in North-east China ... -
Herbivores safeguard plant diversity by reducing variability in dominance
(2018-01)Reductions in community evenness can lead to local extinctions as dominant species exclude subordinate species; however, herbivores can prevent competitive exclusion by consuming otherwise dominant plant species, thus ... -
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 ... -
Producción de lechuga (Lactuca sativa) en hidroponía en sistema Indoor con luces artificiales = Lettuce (Lactuca sativa) production in hydroponics indoor system with artificial lights
(Universidad Nacional de la Patagonia Austral, 2023-12-21)En la localidad de Río Gallegos, el fotoperiodo disminuye en época invernal y lo torna limitante para la producción de hortícolas. Motivo por el cual, para obtener cultivos todo el año en esta zona, es necesario realizar ... -
Producción y calidad de gramíneas en un gradiente de calidades de sitio y coberturas en bosques de Nothofagus antarctica (G. Forster) Oerst. en Patagonia
(Asociación Argentina de Ecología, 2012-04-01)El presente estudio tuvo como objetivo cuantificar la producción y calidad de forraje de las gramíneas que conforman el sotobosque de bosques de Nothofagus antarctica (ñire) sometidos a aprovechamiento silvopastoril, que ... -
Suitable conditions for natural regeneration in variable retention harvesting of southern Patagonian Nothofagus pumilio forests
(SpringerOpen, 2019-06)Background: Variable retention (aggregated and dispersed retention) harvesting proposed for Nothofagus pumilio was designed for timber purposes and biodiversity conservation. Harvesting by opening canopy generates different ...
