The influence of ozone on insect herbivore growth and population development was investigated. Fumigation of both pea (Pisum sativum L.) and dock (Rumex obtusifolius L.) at a range of O(3) concentrations between 21-206 nl litre(-1) produced changes i

The first measurements of spin-rotation in meson-baryon scattering in the resonance region are presented. These measurements, for the reaction π − p → K 0 Λ , confirm the main predictions of a previous partial-wave analysis. Comments are made o

Using simple laboratory systems, an attempt was made to assess the importance of selective collembolan (Onychiurus subtenuis Folsom) grazing on the colonization of L layer leaf litter from a cool temperate deciduous forest by two common litter fungi

Pea aphids feeding from birth to maturity on pea plants ( Pisum sativum ) exposed to SO 2 concentrations of 50 nl litre −1 or 80 nl litre −1 showed a significant 19% increase in the rate of nymph production during the reproductive period, compare

An attempt was made to assess the effect of grazing by Onychiurus subtenuis Folsom on nutrient release from and respiration of a sterile dark fungus using simple microcosms held under controlled laboratory conditions. The results showed that the fung

Sitka spruce trees, with and without the aphid Elatobium abietinum and/or drought treatment, were subjected to 25 nl litre−1 of sulphur dioxide over a 2-month period. Aphids became three times as abundant on the fumigated trees if they were well wa
