Energy cost of contraction in fast and slow muscle fibres isolated from an elasmobranch and an Antarctic teleost fish
Read more of: Energy cost of contraction in fast and slow muscle fibres isolated from an elasmobranch and an Antarctic teleost fish1. Single fast and small bundles of slow fibres were isolated from the muscles of an elasmobranch (dogfish, Scyliorhinus canicula) and an Antarctic teleost (Notothenia neglecta). A third fibre type […]

Evolutionary adaptation to temperature in fish muscle cross bridge mechanisms: tension and ATP turnover
Read more of: Evolutionary adaptation to temperature in fish muscle cross bridge mechanisms: tension and ATP turnover1. Force and ATPase activity were measured in skinned, fast muscle fibres isolated from the myotomes of Antarctic, temperate and tropical fish. 2. Maximum isometric tension was inversely related to […]

Geomagnetic storms in the Antarctic F-region. I. Diurnal and seasonal patterns for main phase effects
Read more of: Geomagnetic storms in the Antarctic F-region. I. Diurnal and seasonal patterns for main phase effectsNew analysis procedures are used to show that the main phase mid-latitude storm effects conform to consistent patterns in local time when suitable selection rules are applied, with averaging over […]

The reproductive biology of Euchaeta antarctica Giesbrecht (Copepoda: Calanoida) at South Georgia
Read more of: The reproductive biology of Euchaeta antarctica Giesbrecht (Copepoda: Calanoida) at South GeorgiaThe reproductive biology of the predatory calanoid copepod Euchaeta antarctica Giesbrecht was investigated in two interconnected fjord systems at South Georgia. Counts of the number of spermatophores attached to adult […]
