The king penguin Aptenodytes patagonicus is a sub-Antarctic species that feeds primarily on mesopelagic fish and cephalopods in the vicinity of the Antarctic Polar Front (APF). We examined the cephalopod […]
Artificial selection pressures imposed by fisheries can impact population structure in the short term and drive evolution of life-history traits in the long term. In exploited squid populations the short […]
Squid are among the fastest-growing short-lived commercial species and, as opposed to most finfish resources worldwide, their contribution to the total world fish production has been increasing at a high […]
Chiroteuthis veranyi (Férussac, 1835) (Cephalopoda: Chiroteuthidae) from South Georgia is described from material collected during the British Antarctic Survey’s Offshore Biological Programme. The material closely resembles C. veranyi from elsewhere […]
The coleoid cephalopods (cuttlefish, squid and octopus) arose from their shelled ancestors during the late Devonian; they diversified in the Jurassic but did not radiate substantially until the Tertiary. Since […]
Historically, the term polar patch was used to describe isolated regions of enhanced 630 nm emission observed in the polar cap. In recent years, signatures from other instruments, such as […]
Whilst it is well-accepted that short-duration changes to the Interplanetary Magnetic Field (IMF) and solar wind cause high-latitude ionospheric transients observed by magnetic, optical and radar techniques, a coherent explanation […]
The Lagrelius Point Formation from its type area in north-west James Ross Island, Antarctica has yielded dinoflagellate cysts indicative of an earliest Aptian age. Reworked palynomorphs presumed to be from […]
A discriminant function using simple carapace measurements corretly determined the sex of 87% of male and 89% of female Antarctic krill Euphausia superba. This facilitated the use of sex-specific regression […]
