Canadians are no strangers to cold winters, when everything in nature appears to be frozen solid. However, under the ice cover of lakes, many animals remain active during the winter.

At first glance, duckweed may seem innocuous and even a little too common to be of any interest. But it’s an excellent source of protein.
Some plant plankton engage in predatory behaviour and consume bacteria. This can contribute to climate change as these plankton stop photosynthesis in warmer temperatures.
In winter 2023-24, the Great Lakes’ ice cover was near record lows, peaking at just 16%. Researchers explain how diminishing ice could have consequences for fisheries, and how species are evolving.
Trees are supposed to grow faster as a result of increased CO₂ in the atmosphere - but this research suggests there are many exceptions to the rule.
Trees – and all plants – harvest sunlight to gain the energy they need to live and grow.
Plants aren’t always as good at photosynthesis as you might think. Our research project wants to help them.
Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.
An unusual lake with distinct layers of low-oxygen and high-iron water lets researchers investigate conditions like those in the early Earth’s oceans.
Many beloved wildflowers bloom in early spring, while trees are still bare and the flowers have access to sunlight. Climate change is throwing trees and wildflowers out of sync.
In the deep, dark ocean, sunlight-deprived bacteria turn to different sources of energy: dissolved hydrogen and carbon monoxide.
Plants have evolved several ways to deal with heavy metals that might otherwise poison or kill them.
People wouldn’t last long without the countless other species we depend on for survival.
Plants lose huge amounts of water to catch the carbon dioxide they need for photosynthesis – but a new discovery may make them more efficient.
Thanks to their high concentrations of phytoplankton, African lakes emit less CO2 than their boreal counterparts, with important consequences for climate modelling.
More carbon dioxide in the air doesn’t necessarily mean more growth for trees, and the increasing risk of wildfires and drought has major consequences, as an interactive map shows.
Rising carbon dioxide in the atmosphere may be a boon for maize crops in tropical growing regions like those found in much of Africa.
Variegated plants can be more expensive than their all-green counterparts. But there are ways to protect your investment.
New research shows that coast redwood trees have a surprising adaptation that helps them thrive in both wet and dry environments.
The growing season on the tundra is starting earlier as the planet warms, but the plants aren’t sequestering more carbon, a new study finds.
