    Effects on microflora of using naphthalene or X-rays to reduce arthropod populations in the field (1987)
    Springer
    Biology and fertility of soils 3 (1987), S. 11-13

    Notes: Summary Naphthalene or X-rays are often used to test the effect on soil processes of reducing or eliminating arthropods. Naphthalene, however, is shown here to reduce radial growth significantly in eight out of nine basidiomycete fungi tested. X-ray treatment, which killed only 24% of Onychiurus latus Gisin (Collembola), significantly reduced the radial growth rate of one of two fungi tested. These techniques are likely to affect the composition of microbial communities and therefore should be used only with extreme caution in field manipulation experiments involving fauna-microflora interactions.

    The effects of chrysomelid beetle grazing and plant competition on the growth of Rumex obtusifolius (1986)
    Springer
    Oecologia 70 (1986), S. 452-456 
    Details
    ISSN: 1432-1939
    Keywords: Grazing ; Plant competition ; Growth ; Gastrophysa ; Rumex
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The interaction between grazing by Gastrophysa viridula and interspecific plant competition was investigated for Rumex obtusifolius growing in the field. During an eight-month growing season non-competing R. obtusifolius grew larger than competing plants although herbivore loads (beetle productivity per unit leaf area) were similar for competing and non-competing plants. However, grazing significantly reduced the growth of R. obtusifolius only in competing plants thus demonstrating a synergism between plant competition and invertebrate herbivory. The relevance of these findings for the distribution of plant species is discussed.

    The diet and food preferences of Onychiurus procampatus (Collembola) from upland grassland soils (1993)
    Springer
    Biology and fertility of soils 16 (1993), S. 296-298 
    Details
    ISSN: 1432-0789
    Keywords: Collembola ; Food preferences ; Grassland ; Fungi ; Gut contents
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Geosciences , Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Specimens of Onychiurus procampatus (Collembola) observed grazing on fungal mycelia were collected from the surface soil of three differently manged upland grasslands. A general trend of an increasing proportion of Collembola with a full gut was found along a gradient of reduced sheep management intensity, which was correlated with increased fungal biomass. In the laboratory, this collembolan showed a consistent order of preference for the mycelium of seven common fungal species isolated from the field sites.

    Nutritional therapy of hospitalized patients with inflammatory bowel disease (1987)
    Springer
    Digestive diseases and sciences 32 (1987), S. S89

    Topics: Medicine
    Notes: Abstract The use of total parenteral nutrition and enteral nutrition in inflammatory bowel disease has become commonplace. Except for well-documented improvements in nutritional parameters, the efficacy of these treatments for primary therapy or for complications remains largely unproven.
