Fish evolve by playing it safe

New research supports the creation of more marine reserves in the world’s oceans because, the authors say, fish can evolve to be more cautious and stay away from fishing nets. The research suggests that by creating additional “no-take” areas, some fish will stay within marine reserves

Researchers collaborate on climate change as cause of wetland die-off

Researchers from Nipissing University’s Geography department are part of a study published in the journal Marine and Freshwater Research that points a finger at climate change as the cause of a massive wetland die-off in Australia. Geography professor Dr. John Kovacs and his summer re

Under the Dead Sea, Warnings of Dire Drought

Nearly 1,000 feet below the bed of the Dead Sea, scientists have found evidence that during past warm periods, the Mideast has suffered drought on scales never recorded by humans—a possible warning for current times. Thick layers of crystalline salt show that rainfall plummeted to as

Salmon with side effects

Tasty, versatile, and rich in essential omega-3 fatty acids: salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms which can pollute rivers, lakes and oceans. Just how big is the problem? German a

Boulder scientist teams on study probing implications of ice sheet's demise

Flying over the remote during research at the Barnes Ice Cap on Baffin Island in 2009, a Boulder scientist saw dark where there should have been white. Closer inspection revealed that what Gifford Miller spotted was the remnants of a 1963 geological camp that had been buried for decad

2017 U.S. Wildfire Season Off to an Intense Start

Wildfires have consumed more than 2 million acres of U.S. land so far this year, nearly 10 times the long-term average and a punishing start to this year’s wildfire season, according to data from the National Interagency Fire Center (NIFC). Massive grass-fed fires across Kansas, Oklah

The foundation of aquatic life can rapidly adapt to global warming, new research suggests

Important microscopic creatures which produce half of the oxygen in the atmosphere can rapidly adapt to global warming, new research suggests. Phytoplankton, which also act as an essential food supply for fish, can increase the rate at which they take in carbon dioxide and release oxy

Changing Temperatures and Precipitation May Affect Living Skin of Drylands

Arid and semiarid ecosystems are expected to experience significant changes in temperature and precipitation patterns, which may affect soil organisms in ways that cause surfaces to become lighter in color and thus reflect more sunlight, according to a new U.S. Geological Survey study

Parasitic Fish Offer Evolutionary Insights

Lamprey are slimy, parasitic eel-like fish, one of only two existing species of vertebrates that have no jaw. While many would be repulsed by these creatures, lamprey are exciting to biologists because they are so primitive, retaining many characteristics similar to their ancient ance

Dead Zones May Threaten Coral Reefs Worldwide

Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study by Smithsonian scientists published in the Proceedings of the National Academy of Sciences. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspect
