    The age, growth and diet of a freshwater population of the flounder, Platichthys flesus (L.), in southern England (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 25 (1984), S. 0 
    Details
    ISSN: 1095-8649
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Biologie
    Notizen: Otoliths from 640 flounders from the River Frome, a chalk river in southern England, were used for age and growth studies together with length-frequency data. Mean lengths at ages I–V were 89, 151, 225, 304 and 323 mm respectively; these are higher than have been reported for marine populations. All flounders caught were immature and, on reaching the sea, both sexes probably became sexually mature a year older than did the marine populations. Flounder diets in freshwater comprised largely aquatic insects, Mollusca and Crustacea but there were differences between large and small fish; seasonal changes in diet largely reflected prey availability. It is suggested that competition for food and space in estuaries between 0 group flounders have given rise to the migration into fresh water.

    The growth and reproductive strategy of the gudgeon, Gobio gobio (L.), in two hard-water rivers in southern England (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 17 (1980), S. 0 
    Details
    ISSN: 1095-8649

    Thema: Biologie
    Notizen: Scales from 682 gudgeon from the River Frome and 504 from the River Stour were used for age determinations. Growth in length was confined to the period May to October, but some weight increase occurred during the winter because of gonad development. Growth rates in the two rivers were the same, and were higher than most of those reported from other European rivers. Wide fluctuations, up to 12-fold, occurred in the year-class strengths of Frome gudgeon, caused by variations in the survival of juvenile gudgeon in their first year of life. Density-independent factors, particularly water temperature, were major influences. Female gudgeon grew marginally slower than the males, but they matured earlier and at a smaller size. They were fractional spawners but their total reproductive effort each season was high. Both sexes had low survival rates and their reproductive life spans were rarely more than three years. These life history traits support the premise that these gudgeon populations are r-selected.

    Beschreibung / Inhaltsverzeichnis: Zusammenfassung Bei Tatauierungen lassen sich elektronenmikroskopisch in den ersten 27 Tagen morphologische Zeichen einer Fremdkörperreaktion nachweisen. In der akuten leukocytären Phase und der anschließenden histiocytär-makrophagischen Phase werden die chemischen Zusatzstoffe der Tusche beseitigt. Nach 14 Tagen lagern sich Makrophagen aneinander und konfluieren allmählich zu Riesenzellen.
    Notizen: Summary Electron-microscopic evidence of morphological signs of foreign body reactions can be seen in the first 27 days after tattooing. The chemical additives of china ink are eliminated in the acute leukocyte phase and the following histiocytic-macrophagic phase. The macrophagic cells move together and gradually confluence to form giant cells within 14 days.

    L-shell vacancy production in Ag, Ta and Au for incident ionsZ 1≦10 in the energy range of 0.125–4 MeV/amu (1981)

    Notizen: Abstract Absolute Ag, Ta and AuL-shell X-ray cross sections were measured using protons,4He,14N as well as20Ne ions in the energy range of 0.125–4 MeV/amu. By means of single-hole fluorescence yields experimental ionization cross sections were deduced and compared with calculations according to the corrected PWBA model — PWBA(BPCR). With decreasing asymmetry of the collision system the experimental cross sections exceed the predictions of the direct ionization theory. This is caused by an increasing contribution of a competing KL charge exchange mechanism which was investigated in detail for Ne+Ag. The Lapicki and Losonsky capture model was found to fail at energiesE〈1 MeV/amu because adiabatic relaxation effects in the projectileK-shell become important. An estimation by means of the Nikitin model led to more physically comprehensible results at the lowest ion velocities investigated.

    Collision broadening in MO-electron spectra in Kr-Kr and Kr-Ar collisions (1981)
    Springer
    The European physical journal 302 (1981), S. 191-193 
    Details

    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract The energy spectrum of MO Auger electrons produced in ion-atom collisions is determined by the behaviour of the energyE(R) and the autoionizing widthΓ A (R) of a quasimolecular level as a function of the internuclear distanceR and by the collisional broadening mechanism. The collisional broadening (cb) of a MO-electron spectrum is caused by the nuclear motion and mainly concerns transitions between the quasimolecular autoionizing state and the continuum. In the present work the dependences of cb on the projectile velocityv p and on the united atomic numberZ of the projectile-target systems are studied.
