Climate change may reduce vulnerable salmon populations

April 07, 2016

New research in north-central Mongolia illuminates the effects of global climate change on certain vulnerable species of salmon.

Air temperature records demonstrate that in the last 40 years, Northern Mongolia's rate of warming has been 3-times greater than the northern hemisphere average. Streamside measurements indicate that salmon metabolism has increased exponentially with temperature, and the fish are now experiencing temperatures near their upper levels for growth during summer.

"Because of the remote location of many Northern Mongolian rivers, the fish populations are generally in great shape. However, many of the salmonid species in Mongolia are already living near the limits of their ability to withstand warm water," said Dr. Kyle Hartman, co-author of the Ecology of Freshwater Fish study. "As the climate here continues to warm, these species could be pushed out of one of their last refuges in the world," added co-author Dr. Olaf Jensen.

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
