A phylogenetic study of the squid family Onychoteuthidae (Cephalopoda: Oegopsida)
Read more of: A phylogenetic study of the squid family Onychoteuthidae (Cephalopoda: Oegopsida)The oegopsid squid family Onychoteuthidae presently comprises six genera (Moroteuthis, Onychoteuthis, Ancistroteuthis, Kondakovia, Onykia and Chaunoteuthis) but the status of some of these is still uncertain. An interdisciplinary study was […]

New seismic data support Cenozoic rifting in George VI Sound, Antarctic Peninsula
Read more of: New seismic data support Cenozoic rifting in George VI Sound, Antarctic PeninsulaNew multifold seismic‐reflection and wide‐angle reflection/refraction data across George VI Sound, Antarctic Peninsula, show the presence of graben and horst structures indicating an extensional origin. The data suggest that rocks […]

Seasonality of polypide recycling and sexual reproduction in some erect Antarctic bryozoans
Read more of: Seasonality of polypide recycling and sexual reproduction in some erect Antarctic bryozoansThe seasonality of polypide cycling has been investigated for three species of erect bryozoans from Antarctica: Isoseculiflustra rubefacta (Kluge, 1914), Nematoflustra flagellata (Waters, 1904) and Himantozoum antarcticum (Calvet, 1905). Approximately […]
