    Notizen: Abstract Adult male mice from the substrains DBA/2JNmg and DBA/2J were individually placed into a novel environment and compared for nine behavioral components. The substrains differed in three vertically oriented exploratory acts, the latter showing the highest rates. On the basis of the breeding history of strain DBA/2, it is concluded that over the past years one or more mutations with an effect on behavior have occurred in at least these sublines of an old and widely used inbred mouse strain.

    Acid fog and ozone: Their possible role in birch deterioration around the Bay of Fundy, Canada (1989)
    Springer
    Water, air & soil pollution 48 (1989), S. 263-276 
    Details
    ISSN: 1573-2932
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Energietechnik
    Notizen: Abstract The area of deterioration in white birch stands adjacent to the Bay of Fundy overlaps with the area intercepting the often acidic “Fundy Fog” (mean pH 3.6 April to October). The fogs deposit substantial, and previously undetected, amounts of acidity (0.1 – 0.5 keq ha−1) which rival and may exceed the input by rain to the stands. Preliminary data (1987) suggest a relationship between fog acidity, nitrate levels (P〈0.01 and P〈0.05 respectively), and foliar browning occurring at each site. Acidity tends to increase inland, which may indicate rapid conversion of dissolved SO2 in fog droplets to SO4. The relationship with O2 was not significant at the 0.05 level. Browning is more extensive on older leaves, suggesting cumulative damage and increasing susceptibility to secondary attack by leaf spot fungus. Although the direct effect of ozone on browning is unresolved, its role in controlling fog chemistry warrants further investigation.
