    Notes: Abstract The intertidal polychaete Euzonus mucronata (Treadwell) is found in great numbers within beach sands that undergo periodic anoxia. Short-term exposures (2 to 4 h) to anaerobicity are withstood through the use of a supply of oxyhemoglobin to support continued aerobic metabolism. Longer periods of environmental anoxia activate an anaerobic metabolism capable of sustaining life for up to 20 days, and characterized by the excretion of succinate and propionate. These two mechanisms appear to be adaptations to the variations in occurrence and duration of anoxia within the intertidal sands inhabited by E. mucronata.

    Chromosome distribution in neuroblast metaphase cells of Locusta migratoria L. (1975)

    Notes: Abstract Chromosome distribution has been investigated at metaphase and C-metaphase in neuroblast cells of Locusta migratoria embryos. There is no evidence for generalised somatic association of homologues or nucleolus organising chromosomes at either stage. Homologous chromosomes 9 are found closer together than expected in C-metaphase but this seems to be due to their tendency to lie in the centre of the C-metaphase squash. (Summary see p. 332.)
