The seasonal and annual variation in the litter fall of epiphytic lichens and tree litter was studied over a period of 2 to 3 years at two forested hills in the eastern part of central Sweden. Litter fall was measured using traps and for one species, Usnea longissima, by collecting specimens present on the ground. Total litter fall amounted to 2.5 and 2.8 tons ha−1 year−1 of which lichens constituted 4.6 and 5.7% at the two sites. Lichen litter fall was highest during the period from late autumn to the beginning of summer. Both the lichens and the tree litter showed significant between-year differences. Usnea longissima had an annual turnover of 7.0 and 10.0% of the standing crop at the two sites. The thallus length distribution of U. longissima was positively skewed. It is concluded that dispersal of thallus fragments by wind evidently plays an important role for many of the filamentous lichens studied. It is suggested that U. longissima disperses over a much shorter distance than Alectoria sarmentosa and Bryoria spp. within a forest stand.

Seventeen isolates of the aphid-borne barley yellow dwarf virus (BYDV), collected in southern Manitoba in 1966, were transmitted from oats to oats most efficiently by Rhopalosiphum padi. They were transmitted also by Macrosiphum avenae and all but two were transmitted by Schizaphis graminum and Acyrthosiphon dirhodum. Most of these isolates were not transmitted by R. maidis.Only 3 of 25 isolates collected in 1967 were transmitted by the five species of aphids in a pattern similar to that of the isolates collected in 1966. Twenty of the remainder were transmitted with a moderate to high degree of specificity by R. maidis, R. padi, or S. graminum. Two of the latter isolates were transmitted only by S. graminum. When the transmissibility of one of the isolates, for which S. graminum was the most efficient vector, was examined more critically, both the relative and the specific efficiency of the three vectors varied with the age of the infection in the source plants, though S. graminum was always the most efficient vector.
