Imperiled, some freshwater mussels endure. How?

Freshwater mussels are among the most imperiled animals in North America, yet some colonies have managed to persevere despite habitat loss, pollution and other threats.

Greenhouse gas 'feedback loop' discovered in freshwater lakes

A new study of chemical reactions that occur when organic matter decomposes in freshwater lakes has revealed that the debris from trees suppresses production of methane—while debris from plants found in reed beds actually ...

New tool for the early detection of blue-green algae

Algae and/or cyanobacteria blooms are increasingly invading Quebec's waters, with some 500 bodies of water affected in the past 10 years. Methods for tracking these microorganisms are costly and labour-intensive, but satellite ...

Researchers discover neurotoxin in Lake Winnipeg

A new study from UBC's Okanagan campus has found that BMAA—a toxin linked to several neurodegenerative diseases—is present in high concentrations during cyanobacteria blooms in Lake Winnipeg.

Tracking the viral parasites of giant viruses over time

In freshwater lakes, microbes regulate the flow of carbon and determine if the bodies of water serve as carbon sinks or carbon sources. Algae and cyanobacteria in particular can trap and use carbon, but their capacity to ...
