Cytogenetic characterisation of the razor shells "Ensis directus" (Conrad, 1843) and "E. minor" (Chenu, 1843) (Mollusca: Bivalvia)

González-Tizón, Ana M.; Rojo Oróns, Verónica; Vierna Fernández, Joaquín; Jensen, K. Thomas; Egea, Emilie; Martínez-Lage, Andrés (Springer Nature, 2012-04-26)

[Abstract] The European razor shell Ensis minor (Chenu 1843) and the American E. directus (Conrad 1843) have a diploid chromosome number of 38 and remarkable differences in their karyotypes: E. minor has four metacentric, ...
Population genetic analysis of "Ensis directus" unveils high genetic variation in the introduced range and reveals a new species from the NW Atlantic

Vierna Fernández, Joaquín; Jensen, K. Thomas; González-Tizón, Ana M.; Martínez-Lage, Andrés (Springer Nature, 2012-07-31)

[Abstract] We report current genetic variation of populations of the razor shell Ensis directus (Conrad 1843) (Mollusca: Bivalvia: Pharidae) in native (North American) and introduced (European) ranges using nuclear and ...
The linked units of 5S rDNA and U1 snDNA of razor shells (Mollusca: Bivalvia: Pharidae)

Vierna Fernández, Joaquín; Jensen, K. Thomas; Martínez-Lage, Andrés; González-Tizón, Ana M. (Nature, 2011-08)

[Abstract] The linkage between 5S ribosomal DNA and other multigene families has been detected in many eukaryote lineages, but whether it provides any selective advantage remains unclear. In this work, we report the ...
