    Rate-compensated synaptic events in antarctic fish: Consequences of homeoviscous cold-adaptation (1986)
    Springer
    Cellular and molecular life sciences 42 (1986), S. 806-808 
    Details
    ISSN: 1420-9071
    Keywords: Antarctic fish ; synaptic currents ; decay rates ; cold adaptation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary At ambient sub-zero temperatures, muscles from antarctic fish produce spontaneous postsynaptic currents (MEPCs) of significantly shorter duration than those of temperate fishes. Fast decay of antarctic MEPCs is a predictable consequence of the increased membrane fluidity attributable to fatty acid unsaturation in cold-adapted animals.

    Antarctic fishes survive exposure to carbon monoxide (1992)
    Springer
    Cellular and molecular life sciences 48 (1992), S. 473-475 
    Details
    ISSN: 1420-9071
    Keywords: Antarctic fish ; oxygen transport ; haemoglobin ; carbon monoxide
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract The extensive in vivo conversion of haemoglobin to the carbon monoxide derivative has no discernible effect on the survival of the red-blooded Antarctic fishPagothenia bernacchii. Analysis of caudally sampled blood of cannulated specimens revealed that reconversion of carbon-monoxy haemoglobin to oxyhaemoglobin was complete within 48 hours. Thus, under stress-free conditions, haemoglobin is not necessary for survival ofP. bernacchii. Red-blooded Antarctic fishes can carry oxygen necessary for routine delivery dissolved in plasma, in a similar way to the haemoglobinless Channichthyidae, although they lack the morphological and physiological adaptations which allow the latter to prosper without any haemoglobin.
