    Sulfate assimilation in Rhodopseudomonas globiformis (1981)
    Springer
    In:  Archives of Microbiology, 130 (3). pp. 234-237.
    Details
    Publication Date: 2016-01-21
    Description: Rhodopseudomonas globiformis is able to grow on sulfate as sole source of sulfur, but only at concentrations below 1 mM. Good growth was observed with thiosulfate, cysteine or methionine as sulfur sources. Tetrathionate supported slow growth. Sulfide and sulfite were growth inhibitory. Growth inhibition by higher sulfate concentrations was overcome by the addition of O-acetylserine, which is known as derepressor of sulfate-assimilating enzymes, and by reduced glutathione. All enzymes of the sulfate assimilation pathway. ATP-sulfurylase, adenylylphosphate-sulfotransferase, thiosulfonate reductase and O-acetylserine sulfhydrylase are present in R. globiformis. Sulfate was taken up by the cells and the sulfur incorporated into the amino acids cysteine, methionine and homocysteine. It is concluded, that the failure of R. globiformis to grow on higher concentrations of sulfate is caused by disregulation of the sulfate assimilation pathway. Some preliminary evidence for this view is given in comparing the activities of some of the involved enzymes after growth on different sulfur sources and by examining the effect of O-acetylserine on these activities.

    Cephalopod remains in regurgitations of black-browed and grey-headed albatrosses at South Georia (1981)
    British Antarctic Survey
    In:  British Antarctic Survey Butlletin, 54 . pp. 1-7.
    Details
    Publication Date: 2020-06-15
    Description: 122 regurgitations by adults and chicks of the small grey-headed and black-browed albatrosses (mollymauks) included, besides flesh remains, 421 upper beaks (mandibles) and 422 lower beaks of cephalopods. The lower beaks and some flesh remains were identified, their lower rostral lengths were measured and the wet weight of squids represented by beaks was estimated. Nine species of squid and one octopod were identified. In both species of albatross, the muscular ommastrephid squid Todarodes is the principal squid in the diet, contributing 88% of the beaks and an estimated 91% of the weight of cephalopods represented by beaks in grey-headed albatrosses and 68% of the beaks and 76% of the weight in black-browed albatrosses. Second in importance in the diet is a cranchiid Mesonychoteuthis sp. A, which contributes 8% and 25% by number and 4% and 12% by weight to the diet of grey-headed and blackbrowed albatrosses, respectively. The eight remaining species are each represented by either one or two lower beaks. These samples are compared with samples from sperm whale stomachs and wandering albatrosses also collected near South Georgia.

    Cephalopod remains in regurgitations of the wandering albatross diomedea exulans L. at south georgia (1981)
    British Antarctic Survey
    In:  British Antarctic Survey Butlletin, 54 . pp. 9-21.
    Details
    Publication Date: 2020-06-15
    Description: Regurgitations of the chicks of wandering albatrosses near their nests included 762 upper beaks (mandibles) and 532 lower beaks of cephalopods. Twenty-five species of cephalopod are present in the diet. Analysis of the complete samples shows the three most important species in the diet to be Kondakovia longimana (40.0% by number), Taonius pavo (16.9%) and Histioteuthis(?) eltaninae (8.7%). While the large Taningia danae only comprises 1.3% by number, it may contribute over 5% by weight. The species and size ranges of beaks are compared with those occurring in the stomachs of sperm whales killed by whalers in the Southern Hemisphere (Clarke, 1980). The ten complete samples contain an average of 44 beaks which probably represents about 200 days' accumulation. Both Antarctic and warm-water cephalopods are present in the diet. These albatrosses possibly scavenge some of thei food from vomit of sperm whales.

    Biology of Octopus vulgaris off the east coast of South Africa (1981)
    Springer
    In:  Marine Biology, 65 (1). pp. 1-12.
    Details
    Publication Date: 2021-05-05
    Description: The biology of Octopus vulgaris Cuvier inhabiting subtropical littoral reefs off the east coast of South Africa was investigated. Analyses of stomach contents and lair middens revealed that the mussel Perna perna was the dominant food organism. Growth rate of captive individuals was higher than has previously been recorded but food conversion was lower. Females became sexually mature at 900 g which is estimated to be attained in 3.6 months. Males became sexually mature at 400 g, which is estimated to be attained after 3 months. Results indicate that females live for 9–12 months and have the potential to reach 4 000 g in 240 d while males live for about 12–15 months and have the potential to achieve 4 000 g in 290 d. Mating and breeding occurred throughout the year although evidence for the seasonal migration of females is presented and discussed in relation to breeding and feeding behaviour.
