    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.

    Ultrastructure of exocrine prothoracic gland ofDatana ministra (Drury) (Lepidoptera: Notodontidae) and the nature of its secretion (1986)
    Springer
    Journal of chemical ecology 12 (1986), S. 2039-2050 
    Details
    ISSN: 1573-1561
    Keywords: Datana ministra ; Lepidoptera ; Notodontidae ; exocrine prothoracic gland ; ultrastructure ; dispersal pheromone ; dodecanol ; dodecyl acetate ; dodecyl formate
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Datana ministra larvae possess a gland situated in the ventral anterior portion of the prothorax. The gland consists of a single sac and is only charged with secretion in the last instar. Its orifice, a simple slit, opens into a transverse invagination of the integument in the cervical margin of the prosternite. The components of the gland have been identified by GC and GCMS and have been shown to be dodecanol, dodecyl acetate, and dodecyl formate. The morphology of the gland and the chemistry of the secretion are discussed in relation to other notodontid larvae which have been investigated. It is conjectured that the secretion is not defensive in nature but may function as a dispersal pheromone.

    Morphology of the prothoracic defensive gland ofSchizura concinna (J.E. Smith) (Lepidoptera:Notodontidae) and the nature of its secretion (1979)
    Springer
    Journal of chemical ecology 5 (1979), S. 165-177 
    Details
    ISSN: 1573-1561
    Keywords: Schizura concinna ; Lepidoptera ; Notodontidae ; prothoracic ; defensive gland ; allomone ; defensive secretion ; decyl acetate ; dodecyl acetate ; 2-tridecanone
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The larval defensive gland ofSchizura concinna (J.E. Smith) is situated in the thorax and consists of two sacs joined by an interglandular neck. Its orifice opens into a transverse invagination of the integument at the cervical margin of the prosternite. The major component of the defensive secretion, formic acid, was identified as itsp-bromophenacyl ester. Ancillary components decyl acetate, dodecyl acetate, and 2-tridecanone from the anterior portion of the gland were identified by GLC and GS-MS.
