Modern and early Holocene mollusc fauna of the Ounianga lakes (northern Chad): implications for the palaeohydrology of the central Sahara doi Spatial
The fresh and saline lakes of Ounianga Kebir and Serir in northeastern Chad are among the very few permanent aquatic
ecosystems currently existing in the hyper-arid core of the Sahara desert. The confirmed modern fauna of aquatic molluscs at
Ounianga comprises three widespread species (Melanoides tuberculata, Biomphalaria pfeifferi and Lymnaea natalensis), of which
only the first appears to maintain a thriving population. We recovered seven more species of gastropods, among which one is new to
science...

Climatic change recorded in the sediments of the Chew Bahir basin, southern Ethiopia, during the last 45,000 years Spatial
East African paleoenvironments are highly variable, marked by extreme fluctuations in moisture
availability, which has far-reaching implications for the origin, evolution and dispersal of Homo sapiens
in and beyond the region. This paper presents results from a pilot core from the Chew Bahir basin in
southern Ethiopia that records the climatic history of the past 45 ka, with emphasis on the African
Humid Period (AHP, w15e5 ka calBP). Geochemical, physical and biological indicators show that Chew
Bahir...

This paper presents results from a pilot core from the Chew Bahir basin in southern Ethiopia that records the climatic history of the past 45 ka, with emphasis on the African Humid Period (AHP, ∼15–5 ka calBP).
