Dehesas are Mediterranean agro-sylvo-pastoral systems sensitive to climate change. Extreme climate conditions forecasted for Mediterranean areas may change soil C turnover, which is of relevance for soil biogeochemistry modeling. The effect of climate change on soil organic matter (SOM) is investigated in a field experiment mimicking...

Background and aims: Forecasted climate change and overgrazing are threatening the sustainability of dehesas, human-managed ecosystems where pastures, livestock and scattered trees coexist. Pasture quality is particularly sensitive to these global-change drivers, but there are still many gaps to broaden knowledge about the interactive effects...

Increasing air temperatures and decreasing rainfall can alter Mediterranean ecosystems, where summer heat and drought already limit plant regeneration. Manipulative field studies can help to understand and anticipate community responses to climate changes. In a Mediterranean oak wooded pasture, we have investigated the effects of warming (W,...

Se estudian, desde una perspectiva multivariante, las relaciones entre la composición química de hojas vivas, desfronde, hojarasca y suelo subyacente, en 20 individuos de Quercus canariensis y Q. suber del Parque Natural 'Los Alcornocales' (Cádiz-Málaga). En todos los materiales analizados se detecta una tendencia principal de variación de la...
