AFLPs resolve phylogeny and reveal mitochondrial introgression within a species flock of African electric fish (Mormyroidea: Teleostei).
Estimating species phylogeny from a single gene tree can be especially problematic for studies of species flocks in which diversification has been rapid. Here we compare a phylogenetic hypothesis derived from cytochrome b (cyt b) sequences with another based on amplified fragment length polymorphisms (AFLP) for 60 specimens of a monophyletic riverine species flock of mormyrid electric fishes co...
متن کاملDiscovery and phylogenetic analysis of a riverine species flock of African electric fishes (Mormyridae: Teleostei).
The evolution of species-specific mate recognition signals is of particular interest within speciose monophyletic groups with restricted distributions (known as "species flocks"). However, the explosive nature of speciation in these clades makes difficult the reconstruction of their phylogenetic history. Here we describe a species flock of riverine mormyrid fishes from west-central Africa in wh...
متن کاملMolecular systematics of the African electric fishes (Mormyroidea: teleostei) and a model for the evolution of their electric organs.
We present a new molecular phylogeny for 41 species of African mormyroid electric fishes derived from the 12S, 16S and cytochrome b genes and the nuclear RAG2 gene. From this, we reconstruct the evolution of the complex electric organs of these fishes. Phylogenetic results are generally concordant with earlier preliminary molecular studies of a smaller group of species and with the osteology-ba...
متن کاملDevario in Bangladesh: Species diversity, sibling species, and introgression within danionin cyprinids (Teleostei: Cyprinidae: Danioninae)
Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D. coxi, new species, and D. devario. Devario aequipinnatus has a wide distribution in northern India and Bangladesh. Devario coxi, from southeastern Bangladesh near Cox's Bazar, differs from D. aequipinnatus in mtDNA (COI, p-distance 1.8%), colouration, proportional measurements, and meristics. The minor morph...
متن کاملA morphological study on species of African Mormyrus (Teleostei: Mormyridae) and their electric organ discharges
African Journal of Aquatic Science is co-published by NISC (Pty) Ltd and Taylor & Francis To the best of our knowledge, all the c. 200 known mormyrid fish species of Africa, including the Mormyrus species of the present study, possess electric organs for communication and electrolocation (reviews by Kramer 1990, Moller 1995, Kramer 1996, Bullock et al. 2005). These organs are located in the cau...
