To identify the evolution of soils (salinity, water regime and nutrients) and vegetation (cover and species diversity) in the last 10 years, and to relate these changes with human activities (agriculture practices and others) in nearby areas.
To identify the role of the soils in nutrients, metals and pesticides retention (natural filter effect).
The project focus on the evolution of soil and vegetation in two mediterranean salt marshes of SE of Spain. In previous studies (1991-1993) we identified plant zonation and edaphic gradients in these salt marhes. Now, the objectives are as follow: 1.- to identify the evolution of soils (salinity, water regime and nutrients) and vegetation (cover and species diversity) in the last 10 years, and to relate these changes with human activities (agriculture practices and others) in nearby areas. 2.- to identify the actual role of the soils in nutrients, metals and pesticides retention (natural filter effect).
The results obtained will help to use the halophyte plants as bioindicators of changes in soil characteristics due to natural (v.g. climate change) or anthropic (v.g. waste water pollution) causes. Finally, the information obtained will be use to revalue ecological functions of explain the ecosystems at several social levels.
