    • Plankton production in the Bay of Villefranche was relatively constant during March and April 1986 but the particle size at which the production occurred was more variable. At the beginning of the study, production was dominated by the larger (ca. 6 mum) flagellates but towards the end it was more or less equally divided between the nano- and picoplankton. There were considerable differences in the estimates of population growth rates, depending on the methods used, but on average the population doubling times were close to 12 hours for autotrophs and 24 hours for heterotrophs. As autotrophs do not grow during the night, each population was therefore doubling once per day. It seemed that each of the nano- or picoplankton populations could adversely affect the growth of the others. This could be either by simple predation or by some form of inhibition. Although nutrient levels in the bay were uniformly low, the addition of nutrients did not always stimulate algal growth. The plankton populations seemed to be both in a state of equilibrium and intense ecological competition.

  • A radiographic analysis of constriction locations for vowels
  • 1991

  • Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
    • Vocal tract area functions estimated from 38 sets of X-rayed vowel articulations collected from the literature and from new X-ray motion films of English and Arabic speech reveal four constriction locations: along the hard palate, along the soft palate, in the upper pharynx and in the lower larynx. Each location is appropriate for a definable class of vowel qualities, confirming the quantal nature of at least this aspect of vowel articulation. The acoustical, physiological and phonological implications are discussed. In a given phonotactic environment the precision of the constricting tongue manoeuvre was good. The only truly language specific difference was a preference for either the midpalatal or prepalatal location for palatal constrictions. The tongue muscles are found to be admirably situated for creating constrictions at the four locations.
