title: A molecular phylogenetic study of the freshwater talitrid amphipod Orchestia cavimana (Crustacea).
abstract: In this paper we performed a molecular phylogenetic study of Orchestia cavimana, the sole talitrid amphipod inhabiting beaches of European freshwater lakes and rivers. For that purpose, we have PCR amplified and sequenced regions of the mitochondrial cytochrome oxidase subunit I (COI) gene, basing our analysis on both nucleotide and amino acid sequences and considering also structural classes of the COI enzyme. Phylogenetic analyses were conducted by neighbour-joining (NJ) and maximum-parsimony (MP) methods comparing homologous sequences of talitrids and other Crustacea. In both NJ and MP trees, O. cavimana shows a basal placement with respect to other talitrid amphipods.
