Soil quality evaluation following the implementation of permanent cover crops in semi-arid vineyards. Organic matter, physical and biological soil properties
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2012)
Artículo / Artikulua,
El establecimiento de cubiertas vegetales permanentes (PGC) en viñedos de zonas semiáridas, con manejo tradicional de suelo desnudo mediante laboreo y aplicación de herbicidas, es controvertido, porque tiene ventajas ...
Long-term mannitol-induced osmotic stress leads to stomatal closure, carbohydrate accumulation and changes in leaf elasticity in Phaselous vulgaris leaves
(Academic Journals, 2010)
Artículo / Artikulua,
The effect of long-term osmotic stress was investigated in leaves of two common bean lines, with contrasting tolerance: Flamingo (tolerant) and coco blanc (sensitive). Water relations, organic solute, ion accumulation ...
Land use change effects on carbon and nitrogen stocks in the Pyrenees during the last 150 years: a modelling approach
(Elsevier, 2015)
Artículo / Artikulua,
In the southern Pyrenees, human population and therefore land uses have changed from forests to pastures, then crops, and back to pastures and secondary forests during the last two centuries. To understand what such rapid ...
Multiple pathway succession in coastal Tsuga heterophylla, Thuja plicata and Abies amabilis forests on northeastern Vancouver Island, British Columbia
(NRC Research Press, 2014)
Artículo / Artikulua,
Sustainable forest practices are often designed to mimic natural disturbance and successional processes, yet succession is poorly understood in many ecosystems. On northeastern Vancouver Island, the ‘disturbance hypothesis’ ...
Importancia de la caracterización de la biomasa de raíces en la simulación de ecosistemas forestales
(Asociación Española de Ecología Terrestre, 2013)
Artículo / Artikulua,
Los análisis de sensibilidad son una herramienta importante para comprender el funcionamiento de los modelos ecológicos, así como para identificar
los parámetros más importantes en su funcionamiento. Además, los análisis ...
Modelos ecológicos: descripción, explicación y predición
(Asociación Española de Ecología Terrestre, 2013)
Artículo / Artikulua,
Los ecosistemas son, por definición, complejos sistemas en los que factores biológicos, climáticos y geológicos se combinan con factores sociales, políticos y económicos para producir una serie de procesos ambientales que ...
Evaluation of the effects of forest management strategies on carbon sequestration in evergreen broad-leaved (Phoebe bournei) plantation forests using FORECAST ecosystem model
(Elsevier, 2013)
Artículo / Artikulua,
In the context of global climate change, it is critical to study how different forest management
practices affect forest carbon sequestration. This is especially important for forest managers
and policy makers who will ...
Impacts of enhanced nitrogen deposition and soil acidification on biomass production and nitrogen leaching in Chinese fir plantations
(NRC Research Press, 2012)
Artículo / Artikulua,
Atmospheric pollution levels in China are increasing quickly. Experience from other polluted regions shows that tree growth could be affected, but long-term effects of N deposition and soil acidification on Chinese forests ...
Pedogenic, mineralogical and land-use controls on organic carbon stabilization in two contrasting soils
(Agricultural Institute of Canada, 2010)
Artículo / Artikulua,
Organo-mineral complexation in soils is strongly controlled by pedogenesis, but the mechanisms controlling it and its interaction with cultivation are not yet well understood. We compared the mineralogy and quality of ...
Protein kinase GCN2 mediates responses to glyphosate in Arabidopsis
(BioMed Central, 2015)
info:eu-repo/semantics/article,
Background: The increased selection pressure of the herbicide glyphosate has played a role in the evolution of glyphosate-resistance in weedy species, an issue that is becoming a threat to global agriculture. The molecular ...
