COS 1-3: CANCELLED-From long-term prediction to spatial modeling of annual grassland response to climate change Academic Article uri icon

abstract

  • Ecosystems dominated by herbaceous vegetation can highlight plant-soil-water relationship and its effect on production processes. Therefore, one of the challenges in ecology is to quantify climate change effects on primary production of annuals. Results/Conclusions:We use field data and a recently published spatio-temporally explicit model to study factors affecting long-term variation in annuals production in two water-restricted ecosystems: semi- arid and mediterranean. Both ecosystems are dominated by annual vegetation. The model was operated in both patch and landscape scales and was executed along 30 years (1979- 2008) at the semi-arid site and along 21 years (1986-1990; 1993-2008) at the mediterranean site. Model predictions were validated against harvested samples that were taken from each site at the end of the growing season, in 15 seasons (1994-2008) at the …
