    Notes: [Auszug] THE study of selective feeding... of soil protozoa, especially amœbæ on a large number of bacterial strains, led to the development of an improved method6 of counting soil Protozoa. In the past, dilution methods7 of estimating Protozoa numbers have suffered, first ...

    Factors Contributing to the Bacteriolytic Effect of Species of Myxococci upon Viable Eubacteria (1946)

    Notes: [Auszug] ALTHOUGH the lytic effect of certain myxobacteria upon the true bacteria (eubacteria) has been known for some years1–4, the mechanism of the process is imperfectly understood, and no one seems hitherto to have studied the possible production of antibiotic substances by the ...

    Notes: [Auszug] ALTHOUGH the genera Dictyostelium and Polysphondylium were created by Brefeld1,2 in 1869 and 1884, no study has been made in Britain of that interesting group, the Acrasieæ, to which they belong. The occurrence of Dictyostelium in Polish and American soils has been recorded by ...

    Notes: [Auszug] EIGHTY-SEVEN strains of very varied bacteria, t_j comprising common and rare strains from soil, pigmented and non-pigmented 'miscellaneous' strains, and a number of plant pathogens, were tested on eight micro-predators belonging to four different groups commonly found in soil. The methods used and ...

    Selection for high and low pupation height inDrosophila ananassae (1993)
    Springer
    Behavior genetics 23 (1993), S. 239-243 
    Details
    ISSN: 1573-3297
    Keywords: Drosophila ananassae ; selection ; high and low pupation height ; polygenes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Psychology
    Notes: Abstract Selection for high and low pupation height inDrosophila ananassae was carried out for 10 generations. Response to selection resulted in rapid divergence in pupation height in replicates of both high and low lines. There was a significant difference in mean pupation height among high, low, and control lines. Regression coefficients for both high and low lines were significantly different from zero. The realized heritability over 10 generations was 45–49 for the high lines and 26–29 for the low lines. The F1 hybrids produced by making reciprocal crosses between high and low lines showed intermediate pupation height. These findings suggest that pupation height inD. ananassae is under polygenic control, with a substantial amount of additive genetic variation.

    Chromosome inversions in Indian Drosophila melanogaster (1990)
    Springer
    Genetica 81 (1990), S. 85-88 
    Details
    ISSN: 1573-6857
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Ten laboratory stocks of Drosophila melanogaster initiated from females collected in different localities in India were analysed for chromosome inversions. Six inversions were found to be present, three in 2L, one in 2R, one in 3L and one in 3R. Out of these six inversions, three are new and are being reported for the first time. Furthermore, this is the first report of inversion polymorphism in Indian D. melanogaster. The persistence of inversion polymorphism in our laboratory stocks of D. melanogaster which were maintained for more than one year under laboratory conditions, suggests some heterotic advantage of inversion heterozygotes.
