* Corresponding author. Abstract – The semi-arid Sahel zone of Africa has suffered several periods of severe drought since about 1950. We have analyzed AVHRR Normalized Difference Vegetation Index (NDVI) over the Sahel for the period 1982-2002, and found extensive areas of increasing NDVI. To verify these changes we have analyzed Landsat TM and ETM+ scenes from 1984-1986 and 1999-2001 for areas...

Genetic variability is an important component in the ability of populations to adapt in the face of environmental change. Here we report the first description of nuclear genetic variability in the only remaining sizable colony of the Mediterranean monk seal (Monachus monachus), located at Cap Blanc (Western Sahara, Mauritania), whose estimated size during the study period (1994-May 1997) was ab...

Abstract. Eastern boundary upwelling ecosystems (EBUEs) are among the most productive marine regions in world's oceans. Understanding degree of interannual to decadal variability Mauritania system is crucial for prediction future changes primary productivity and carbon sequestration Canary Current EBUE as well similar environments. A multiyear sediment trap experiment was conducted at mooring s...
