Résumé

Environmental heterogeneity involves the overall variance of sites within an area, and the way in which the variance between sites changes with the distance separating them. In explant studies, plants are grown in samples of the environment under controlled conditions. Explant studies give conservative estimates of heterogeneity. This paper describes explant trials within a 50 × 50 m area of undisturbed Fagus grandifolia-Acer saccharum forest near Montreal, Quebec. Trials were conducted using Arabidopsis thaliana and another using Hordeum vulgare. Plants were sown into soil cores in the glasshouse, and several characters scored on each, including dry mass at harvest, which is closely related to reproductive success. Random sampling gave substantial and significant estimates of environmental variance for most characters, including all measures of dry mass in both species. (See also 92L/07963 and 08004). -from Authors
