    Breeding for anthocyanin colors in Rosa (1983)
    Springer
    Euphytica 32 (1983), S. 205-216

    Notes: Summary In breeding for color and winter hardiness in Rosa, more than 1200 progeny from 47 families were analyzed for anthocyanin pigments. Cyanin, peonin and pelargonin were found in 99%, 52% and 31% respectively, of the seedlings. Each pigment was highly heritable from seed or pollen parents or both. All showed quantitative inheritance, particularly cyanin and peonin. A system is proposed to explain most of the synthetic pathways and controls for anthocyanin production in roses.

    Biogenic silica and phosphorus accumulation in sediments as indices of eutrophication in the Laurentian Great Lakes (1986)
    Springer
    Hydrobiologia 143 (1986), S. 79-86

    Notes: Abstract Biogenic silica (BSi), total phosphorus (TP), and biologically available phosphorus (AVP) were measured in short cores from Lake Michigan, Lake Erie, and Lake Ontario. Peaks in BSi concentration and peaks in BSi:TP or BSi:AVP ratios provided stratigraphic signals of water column silica (Si) depletion as a response of increased diatom production to P enrichment and decreased diatom production resulting from silica depletion. By contrast the stratigraphic record of P accumulation provided very weak signals of the historical nutrient enrichment in the water column. These results indicate that system P recycling has a higher rate constant than Si recycling and, as a consequence, that relatively small levels of P enrichment can increase diatom production and sedimentation eventually causing Si depletion and Si-limited diatom production in the water mass.
