Loss of water availability and stream biodiversity under land abandonment and climate change in a Mediterranean catchment (Olzinelles, NE Spain).
12 páginas, 7 figuras, 1 tabla. In the north rim of the Mediterranean region, where forest cover is increasing as a result of landabandonment and temperatures are rising as a result of climatechange, there is increasing interest for the effects of such changes on the runoff of water courses.

In the north rim of the Mediterranean region, where forest cover is increasing as a result of landabandonment and temperatures are rising as a result of climatechange, there is increasing interest for the effects of such changes on the runoff of water courses.
