A new study casts doubt as to whether plants will continue to absorb as much carbon dioxide in the future as they have in the past due to declining availability of nitrogen in certain parts of the world.

It’s 5am as we head out onto the outermost pier,  where our trusty vessel awaits. Fog clings to the surface of the water as harbour seals play in the marina’s kelp beds below.

A new way of measuring the relative habitability of freshwater environments for fish and aquatic insects suggests that New Jersey’s water monitoring and treatment standards could use a boost.

Researchers found that when water temperatures heat up for corals, fish ‘tempers’ cool down, providing the first clear evidence of coral bleaching serving as a trigger for rapid change in reef fish behaviour. 

A new U.S. Geological Survey laboratory study of two potentially toxic types of freshwater cyanobacteria, or blue-green algae, found that exposure to salty water can damage the cyanobacteria cells’ walls, causing them to release their toxins into the water.

Scientists studying a valuable, but vulnerable, species of poplar have identified the genetic mechanism responsible for the species’ inability to resist a pervasive and deadly disease. Their finding, published in the Proceedings of the National Academy of Sciences, could lead to more successful hybrid poplar varieties for increased biofuels and forestry production and protect native trees against infection.

With a body the size of a fist and wings that span more than a foot, the big brown bat must gorge on 6,000 to 8,000 bugs a night to maintain its stature.

Ecosystems have a variety of benefits: They provide us with food, water and other resources, as well as recreational space. It is therefore even more important that these systems remain functional and stable – especially in view of climate change or environmental pollution. Ecologists at the University of Zurich and the Swiss Federal Institute of Aquatic Science and Technology (Eawag) have now examined the factors that influence this stability in a unique and comprehensive experiment.

A new analysis of ocean regions around the world shows that bottom trawling, which accounts for a quarter of the world’s seafood harvest and can negatively affect marine ecosystems, occurs on just 14 percent of the seafloor along continental shelves and slopes.

More than 1.5 million Michigan residents and potentially more than hundreds of sites nationwide ­– and counting – have PFAS-tainted water.
