A few species of large trees in the Amazon are responsible for half of the carbon storage and productivity of the Amazon rainforest, according to new research. The authors analysed more than 200,000 trees across 530 forest plots in the Amazon rainforest. They found that half of the carbon stock is controlled by only 150 […]

For a tree out west it’s all about the competition
A study of forests in Western Canada has revealed the forces shaping and changing the make up of a forest over time, are primarily competition among trees, with climate playing a secondary role. Researchers studied data collected between 1958 and 2009 in 1,680 forest plots from British Columbia to Manitoba. They found that competition […]
The Emerald ash borer can attack other tree species
New research shows that the emerald ash borer, an invasive beetle from Asia which has killed millions of ash trees in Canada, can also attack the white fringetree (Chionanthus virginicus). This small shrub, while native to the southeastern United States, is planted ornamentally in Ontario and Quebec. Researchers have found that white fringetrees in three […]
No extra growth in tropical trees due to increased atmospheric CO2 levels
The assumption that increased atmospheric CO2 levels contribute to increased tree growth is being called into question by this study published in Nature Geoscience. Predicting the response of tropical forests is important in the modeling of future climate scenarios. Extra CO2 in the atmosphere is expected to increase tree growth, by improving the trees rate of […]
How will climate change affect sugar maples?
A changing climate means trees will grow in new places, but an experiment with sugar maples shows that other factors – such as soil conditions or seed predation – need to be taken into account as well. Researchers grew maple seedlings on the slopes of a Quebec mountain where climate conditions are more favourable for […]
