    Distribution of airborne pollen and spores and their long distance transport (1978)
    Springer
    Pure and applied geophysics 116 (1978), S. 309-315 
    Details
    ISSN: 1420-9136
    Keywords: Pollen ; Spores ; Transport ; Vertical distribution
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract The atmosphere near the ground contains a mixed population of pollen and spores in the 1 to 90 μm diameter range. Continuous sampling at Rothamsted Experimental Station at 2 m above ground level indicated concentrations averaging 12,000 m−3 over 5 summer months, but 1 million m−3 can occur for short periods. Concentrations change rapidly with locality, season, time of day or night and weather. Normally concentration in the troposphere decreases logarithmically with height. The occurrence of long distance transport of pollen and spores by wind is demonstrated by sampling from aircraft, and supported by much circumstantial evidence. Possible effects of this air spora on the atmosphere may be sought in alterations to: opacity, ionization, condensation nuclei, and sinks for minor gases.

    Development of Fuseaux, Aleuriospores, and Spirals on detached Hairs infected by Ringworm Fungi (1933)
    [s.l.] : Nature Publishing Group
    Nature 131 (1933), S. 836-837 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] So long as hairs infected with Microsporon audouini, Trichophyton gypseum, and other ringworm fungi remain attached to the body, the fungi attacking them consist only of hyphæ and small round spores. These spores arise by the rounding-off and disarticulation of the cells of the hyphæ and may be ...

    Notes: [Auszug] After a dozen tests made during 1954 and 1955 on naturally occurring specimens growing on trees, I can confirm the existence of such charges on the basidiospores of Ganoderma applanatam. Further, in this species most spores carry a positive charge. Tests were made by allowing spores to fall in an ...

    Notes: [Auszug] In studies concerned primarily with fungi pathogenic on crop plants we sampled the air at the height of 2 m. above a potato plot continuously from June 1 to September 30, 1951, using an automatic volumetric spore trap described by Hirst3. In this apparatus, which is based on the cascade impactor of ...

    Notes: [Auszug] In quantitative studies of the air spora, we have observed the regular occurrence of a blue-green alga identifiable microscopically as belonging to the Chroococcaceae, probably Gloeocapsa (Fig. 1). This is a minute unicellular alga forming loose colonies on moist surfaces, either inland or on the ...

    Notes: [Auszug] A KNOWLEDGE of the composition of the spore flora of the air is important to agriculture because it includes crop pathogens, and to medicine because of the occurrence of respiratory allergens. Yet its composition and concentration remain undetermined because there has been no suitable quantitative ...

    Notes: [Auszug] When a plate or cylinder is placed with axis at right-angles to the wind, Sell1, working with droplets, has shown that as the size of the trap is increased an increasing proportion of the air stream is deflected by the streamlines and fails to strike the trap. The percentage of particles deposited ...
