The distribution, biomass and density of various beds of P. australis have been determined for Botany Bay (N.S.W.). Comparisons have been made with sites at Broken Bay, Port Hacking and Jervis Bay and these include observations of other seagrass beds (Zostera capricorni, Heterozostera tasmanica, Halophila ovalis and Halophila decipiens). The P. australis plants observed were all of the broad-leaved (1.0-1.2 cm) variety. The length of leaves appears to be correlated with depth and with degree of exposure to wave action. The distribution of P. australis in Botany Bay is almost entirely restricted to the southern side and is limited to a maximum depth of −3 m compared with −7 to −9 m at other sites. The growth of plants in well-established beds seems to be as vigorous in Botany Bay as elsewhere but flowering is poor and infrequent and the overgrowth of epiphytes is very great at certain seasons. Clearing experiments in Botany Bay indicate that recolonization by surrounding plants or seedlings is extremely slow. Transplant experiments indicate that mature plants will survive transplanting to cleared sites on both the northern and southern sides of the Bay. Evidence for a much more extensive distribution of P. australis in Botany Bay in times past and the possible effects of pollution are discussed. © 1976 ASEG.

The hypothesis that ATP and reductant generated in photosynthetic partial reactions can be used in vivo for energy-requiring reactions other than the photosynthetic carbon reduction cycle is supported by much experimental evidence. When such direct use of photo-produced cofactors occurs, it might be expected that the alternative source of ATP and reductant, i.e. 'dark' respiration, occurs to a smaller extent than in heterotrophic cells. This paper uses data from the literature to compute the CO2/C ratio (CO2 produced in 'dark' respiration processes per C incorporated into cell material) for photolithotrophic and heterotrophic growth of a range of unicellular algae and angiosperms. The minimum CO2/C value observed for heterotrophic growth is similar to, but rather higher than, that calculated using the stoichiometry of known respiratory, biosynthetic and transport reactions for the conversion of carbohydrate and the supplied minerals into a plant of the appropriate composition. However, for unicellular algae the CO2/C for photolithotrophic growth is much lower than either of these values for the heterotrophic CO2/C value, and strongly supports the view that the direct use of photo-produced cofactors for processes other than the photosynthetic carbon reduction cycle is an important aspect of energy metabolism in these organisms. The minimum CO2/C observed is similar to that predicted when dark respiratory reactions serve only to produce essential C skeletons. For angiosperms, the evidence is more equivocal, but is consistent with some direct use of photo-produced cofactors for processes other than CO2 fixation. The spatial separation of energy-requiring processes from chloroplasts could partly account for this smaller emphasis on nonrespiratory energy supply to processes other than CO2 fixation in angiosperms compared with unicellular algae. © 1976 Annals of Botany Company.
