Freshwater ecosystems in Canada and around the world are under siege. Lakes, rivers, ponds and wetlands face many environmental threats, but one that is changing them most rapidly is the spread of ...

Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes ...

Highly stable and easily diffused through wind or ocean currents, microplastics have quickly become ubiquitous in nature, as a consequence of multiple anthropogenic activities. Their accumulations in ...

Most people assume that wildfire harms aquatic ecosystems and fisheries. But such assumptions are being challenged by new research. There is no doubt that under some conditions, especially immediately ...

(Beyond Pesticides, May 6, 2025) A study in Ecology Letters finds “severe degradation of ecosystem functioning in the form of loss of organic matter consumption and dramatic shifts in primary ...

Methane emissions from aquatic ecosystems are potentially a larger source of methane than direct anthropogenic methane sources, such as agriculture or fossil fuel combustion. Aquatic ecosystems and ...

Amid an unusual September heat wave, several major wildfires are raging simultaneously out West. As climate change fuels more severe infernos, a fairly new field of study has emerged to investigate ...

Litter decomposition in aquatic ecosystems is a fundamental process driving nutrient cycling, energy flow and carbon sequestration. Terrestrial plant material that falls into streams, rivers and lakes ...

Methane — a greenhouse gas far more potent than carbon dioxide — plays a major role in controlling the Earth’s climate. But methane concentrations in the atmosphere today are 150% higher than before ...

A man in glasses looks into a fish tank in which fish of many colors are swimming. Ecotoxicologist Bob Wong studies how fish change when exposed to the antidepressant medication fluoxetine. Credit: ...

In devasting cases dotting the globe in recent years, climate warming has led to an increase in the number and severity of destructive wildfires. Climate change projections indicate that environmental ...
