Abstract
Internal plant nutrient transport was studied in a beech, F. sylvatica L., stand during 1971-1973. Defoliation performed by the larvae of the pale tussock moth, D. pudibunda L. (Lepidoptera), occurred in 1972-1973. Leaf litter fall was 3.01 .+-. 0.13, 2.58 .+-. 0.13 and 0.79 .+-. 0.04 ton/ha per yr during 1971, 1972 and 1973, respectively. Precipitation was enriched about 3 times with respect to N, P and K in 1973, compared to 1971. Significant differences between the annual fluxes of P, S, Cu, Mn, Ca, Mg, Na, K and N in total litter fall were found in several cases. Annual stem growth was measured on felled logs. Growth reductions were attributed to leaf consumption. Population ecology of the pale tussock moth is surveyed.This publication has 5 references indexed in Scilit:
