This paper presents a synthesis of experiments conducted in a tropical tree plantation established in 2001 and consisting of 22 plots of 45 m × 45 m with either one, three or six native tree species. We examined the changes in carbon (C) pools (tree

Mixed plantations might contribute to sus- tainable land use because of complementary nutrient use. Our objective was to assess the nutrient economy of five native tree species and their response to different neighbor trees in an experimental plantat

We examined photosynthetic characteristics of 21 tree species from a Panamanian forest differing in successional status. We hypothesized that functional guilds of species, grouped by successional status, would differ in photosynthetic performance and

This study is part of a research program examining the effects of elevated atmospheric carbon dioxide on a pasture. It was designed to examine (i) the interaction between disturbance and the atmospheric CO2 concentration at the community level, and (

We investigated the effects of nitrogen availability and present versus future atmospheric environments (i.e., climate) on the seedling performance of 16 open-pollinated maternal families of Piceamariana (Mill.) B.S.P. over two simulated growing seas

To clarify the physiological basis of maternal inheritance we examined the effect of the thermal environment of mother plants of Echinochloa crus-galli on subsequent seed mass, content and quality. The same plants were grown in a warm and a cold envi

To examine the influence of weather patterns on the flowering of a C4 plant, 11 transplant gardens were sown with seeds of Echinochloa crus-galli var. crus-galli within and beyond the species range. Both the isolated effect of climate and the joint e

We investigated biomass allocation and root architecture of eight tropical species with different successional status, as classified from the literature, along a size gradient up to 5 m. We focused on belowground development, which has received less

Despite the sophistication of contemporary growth chambers, growing conditions cannot be uniformly controlled during experiments. Uniformity trials with bean (Phaseolus vulgaris cv. Spartan) and maize (Zea mays cv. Golden Bantam) in the McGill Univer
