Molecular evidence on the evolutionary and biogeographical patterns of European cyprinids.

摘要: The phylogenetic relationships of 106 European cyprinid taxa were determined based on the complete nucleotide sequence (1140 bp) mitochondrial cytochrome b gene. molecular phylogeny was used (1) to revise current systematics cyprinids, (2) establish utility traditional morphological characters that are widely in Cyprinidae systematics, and (3) discuss alternative hypotheses biogeography family Europe. age major lineages within cyprinids tentatively estimated with a clock showed full agreement fossil record group. Moreover, results provided unambiguous evidence for close affinity some Caucasian Greek endemic (e.g., B. capito brachycephalus Leuciscus keadicus, Barbus graecus, albanicus, respectively) Iberian North African, but not Central European, cyprinids. existence such unexpected refutes classical hypothesis which assumes dispersal fauna from central Europe southern northern Africa during Miocene (and, hence, predicts relationship all Caucasian, Greek, Iberian, African taxa). Instead, Mediterranean realm independent route seems plausible evidence. It is likely new biogeographical scenario proposed here might apply other primary freshwater animals low abilities, including fish, amphibians, invertebrates.
