| Abstract: | In this paper, we analysed the phylogeography of the Critically Endangered fish Chondrostoma lusitanicum (Cyprinidae) endemic to Portugal. A fragment of the mitochondrial cyt b gene and one from the nuclear beta-actin gene were sequenced. The results support recognition of 3 ESU's distributed as follows:
1) Sado River, 2) the Tagus River basin and 3 independent nearby coastal rivers (collectively named "West") and 3) Lagoa de
Albufeira, a small coastal lagoon between Tagus and Sado basins. |
