Biology:Dallia
Dallia (Blackfish) is a genus of mudminnows native to Russia and Alaska. Molecular data indicates the genus is more closely related to Esox and Novumbra than Umbra.[1][2] Dallia diverged from Novumbra + Esox approximately 66 million years ago.[2] The genus was named after American naturalist William Healey Dall.[3]
Species
Three species in this genus are recognized:[4]
- Dallia admirabilis Chereshnev, 1980 (Amguema blackfish)
- Dallia delicatissima Smitt, 1881 (Pilkhykay blackfish)
- Dallia pectoralis T. H. Bean, 1880 (Alaska blackfish)
Mitochondrial sequence data was examined from D. pectoralis and D. admirabilis and did not indicate that speciation within the genus in Russia; however, genetic isolation within Alaska for populations of D. pectoralis could be high and associated with karyotype differences.[5][6][7][8]
Fossil remains of Dallia are known from the Late Miocene near Homer, Alaska, suggesting they were found further south in the past. Pleistocene-aged fossil remains also suggest they ranged significantly more west in Siberia as well.[9]
