Scientists discover new bat species in West Africa
Posted on 3 September 2013
The team, which also included researchers from the Czech University of Life Sciences and the Academy of Sciences, Charles University in the Czech Republic, discovered a wealth of unexpected diversity among Vesper bats in Senegal.
During seven expeditions to the Niokolo-Koba National Park in south-eastern Senegal, and subsequent genetic analysis, the scientists discovered that five species of bats looked similar to other populations in Africa, but differed significantly genetically from them.
Taxonomists are now working on describing formally these new species – Vesper bats (Vespertilionidae) are already the largest family of bats with more than 400 known species. The research is published in Frontiers in Zoology.
The researchers studied 213 vespertilionid bats from Senegal and identified ten species, five of which were significantly genetically different from their nominate species – Pipistrellus hesperidus, Nycticeinops schlieffenii, Scotoecus hirundo, Neoromicia nana and Neoromicia somalica.
One of the research team, Nancy Irwin, of the Department of Biology at York, says: “The fact that these Senegalese bats are unrelated and are different to their cousins in other parts of Africa, suggests that West Africa may have been isolated in the past and formed a refugium, where populations gradually diverged and even acquired new chromosomal configurations.
“This exciting finding confirms that West Africa may represent an underestimated bio-geographic hotspot with many more species to discover.”
