    The mating behavior of individuals ofDrosophila pseudoobscura from New Zealand (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 950-952

    Keywords: Drosophila pseudoobscura ; mating behavior ; divergence ; sterility

    Topics: Biology , Medicine
    Notes: Summary Recently discovered individuals in New Zealand of the North American speciesDrosophila pseudoobscura were analyzed for any divergence in mating behavior. Cultures collected from five localities in North American were mated with a stock from Rotorua, New Zealand. No significant divergence was obtained in any of the within North Americ, and more importantly, between North American and New Zealand mating experiments. Further analyses also showed no development of sterility between recently caught New Zealand and North American flies. We discuss our results in relation to others of this type.

    The sensitive period for yellow phenocopy induction inDrosophila melanogaster (1988)
    Springer
    Cellular and molecular life sciences 44 (1988), S. 618-621 
    Details
    ISSN: 1420-9071
    Keywords: Sensitive period ; phenocopy ; yellow ; survivorship ; Drosophila melanogaster
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Yellow phenocopies ofDrosophila melanogaster were produced by raising larvae on α-DMT contaminated media. Using a survivorship test, the sensitive period for phenocopy induction was found to occur during the third larval instar of development, with increased survivorship at 1% α-DMT compared with lower concentrations. It was also found that treatment with α-DMT significantly slowed development. These findings are related to the relevant morphological and behavioral developmental pathways and to phenocopy induction.

    Comparative electron microscopic study of clear cells in Epidermodysplasia verruciformis and flat warts (1978)

    Description / Table of Contents: Zusammenfassung Bei der Beantwortung der Fragen, ob die Epidermodysplasia verruciformis (E. V.) und die disseminierten Warzen verschiedene Erkrankungen sind, wurde eine vergleichende ultrastrukturelle Studie der epidermalen Klarzellen von zwei Fällen von E.V. und 4 Warzen von 4 Patienten, bei denen 3 unter immunsuppressiver Therapie standen, vorgenommen. Bei der E.V. wurde eine Reduktion der Tonofilamente und des Keratohyalins und bei den flachen Warzen ein zentrifugales Ödem und eine Vakuolisierung festgestellt. Die Zahl der Ribosomen war beim E.V. erhöht und vermindert bei den flachen Warzen. Somit können diese beiden Erkrankungen untereinander differenziert werden und weisen auf eine unterschiedliche Gast-Virus-Beziehung hin.
    Notes: Summary Are Epidermodysplasia verruciformis (E. V.) and disseminated flat warts different diseases? Are there any diagnostic criteria between them? In order to attempt answering these 2 questions, fundamental for prognosis and nosology, a comparative ultrastructural study was made of epidermal clear cells of 2 cases of E. V. and 4 flat warts from 4 patients of whom 3 were under immunosuppression drugs. The reason of cytoplasmic electron translucency was mainly a reduction in tonofilaments and keratohyalin amounts in E. V. and a centrifugal edema and vacuolization in flat warts. On the other hand, the number of ribosomes was raised in E. V. and reduced in flat warts. These findings allow differentiation between the 2 diseases and suggest a possible different host-virus relationship.

    Notes: [Auszug] SIR-In an interesting and provocative article, Halstead1 rejected the anti-darwinian views of the Japanese biologist Imanishi. His rejection is apparently based on his negative impressions of Japanese society. Halstead remarked that: "the ordinary Japanese [is] condemned... to the rigid ...

    Description / Table of Contents: Zusammenfassung Um die Wirkungsweise einer Infektion und die Pathogenität vonMycoplasma-pneumoniae-Infektionen weiter zu erforschen, wurden tierexperimentelle Untersuchungen mit Hamstern und Meerschweinchen durchgeführt. Diese Tiere wurden auf Grund früherer Erfahrungen ausgewählt. Die lokale Antikörperreaktion wurde neben dem Wachstumsverhalten des Erregers gründlich untersucht. Zur Bestimmung der auftretenden pathologischen Veränderungen wurden histologische Untersuchungen vorgenommen. In dem Referat wird die Bedeutung dieser Befunde diskutiert.
    Abstract: Résumé Dans le but de mieux définir le mécanisme d'infection et la pathogénicité deM. pneumoniae, le hamster et le cochon d'Inde ont été utilisés comme modèles expérimentaux. Ces animaux ont été choisis en fonction de l'expérience passée. La réponse locale aux anticorps a été examinée en détail, de même que les modes de croissance des micro-organismes. L'examen histologique a eu pour but de déterminer la nature des lésions constatées. L'importance de ces constatations fait l'objet d'une discussion.
    Notes: Summary In an effort to further delineate the mechanism of infection and pathogenicity ofMycoplasma pneumoniae infections, the hamster and guinea pigs were used as experimental models. These animals were chosen because of previous experience. The local antibody response in addition to organism growth patterns were examined in detail. Histological examination was carried out to determine the pathological lesions which occur. The significance of these findings is discussed.

    Laboratory-induced changes in the mate recognition system ofDrosophila pseudoobscura (1986)
    Springer

    Notes: Abstract Drosophila pseudoobscura stocks maintained in laboratory culture for some time had altered mate recognition systems compared with recently collected control stocks. Three showed a significant deviation from random mating; in one, a tendency toward homogametic mating was recorded. Such deviations are in marked contrast to results from populations which have been recently collected from the field. Asymmetrical mating was observed in two of the crosses in the direction predicted by the Kaneshiro model.

    The stability of the specific-mate recognition system ofDrosophila melanogaster (1986)
    Springer
    Behavior genetics 16 (1986), S. 369-373

    Keywords: specific-mate recognition systems,Drosophila melanogaster ; evolution, mating behavior
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract The present data illustrate an important characteristic of the mate recognition system of individuals ofDrosophila melanogaster. This system showed a high degree of stability, and the stability occurred even though the populations under investigation were divergent in other characteristics. We review the results of other studies of this type, discuss our results in terms of the general characteristics of specific-mate recognition systems, and account for its stability in terms of the structure of the communication system.
