Fishing, climate change not double trouble for corals
Do fishing and climate change act synergistically on coral reef ecosystems, meaning the combined impact is greater than the sum of each acting individually? Conservation practitioners have expressed this concern, but synergism in ecosystems has been challenging to prove scientifically...

A new study on mercury levels in prairie reservoirs finds exceedingly high concentrations in northern pike residing in a newly constructed reservoir in Alberta. In addition, the study suggests the reservoir’s food web is extremely simplified, a factor that could be further exacerbating the elevated levels of mercury...
