Rhachotropis (Eusiroidea, Amphipoda) from the North East Atlantic

Rhachotropis (Eusiroidea, Amphipoda) from the North East Atlantic

The genus Rhachotropis has the widest geographic and bathymetric distribution of all amphipod genera worldwide. Molecular and morphological investigations of specimens sampled around Iceland and off the Norwegian coast allow the first insights into the relationships of North East Atlantic Rhachotropis. The 31 cytochrome oxidase subunit I (COI) sequences generated for this study were assigned 13...

An enigmatic Rhachotropis (Crustacea: Amphipoda: Eusiridae) from New Zealand.

The eusirid genus Rhachotropis S.I. Smith, 1883 has a worldwide distribution and the largest bathymetric range known from any amphipod genus. A large, charismatic, colourful species was collected below 800 m at two sites 1000 km apart on the southern Kermadec Ridge and on the Chatham Rise in the south-western Pacific off eastern New Zealand. The new species, Rhachotropis oweni is described, inc...

Mapping of C4 plant input from North West Africa into North East Atlantic sediments

Mapping the abundance of C in leaf-wax components in surface sediments recovered from the seafloor off northwest Africa (0–35°N) reveals a clear pattern of dC distribution, indicating systematic changes in the proportions of terrestrial C3 and C4 plant input. At 20°N latitude, we find that isotopically enriched products characteristic of C4 plants account for more than 50% of the terrigenous in...
