Global ice loss increases at record rate

(University of Leeds) The rate at which ice is disappearing across the planet is speeding up, according to new research. And the findings also reveal that the Earth lost 28 trillion tonnes of ice between 1994 and 2017 – equivalent to a sheet of ice 100 metres thick covering the whole of the UK.

Shift in caribou movements may be tied to human activity

(University of Cincinnati) Human activities might have shifted the movement of caribou in and near the Arctic National Wildlife Refuge, according to scientists who tracked them using isotopic analysis from shed antlers. The study is timely given the auction this year of oil and gas leases in the Arctic National Wildlife Refuge. Indigenous Alaskans opposed the leases, arguing development could disrupt the migration of caribou they depend on for sustenance.

Researchers prove fish-friendly detection method more sensitive than electrofishing

Delivering a minor electric shock into a stream to reveal any fish lurking nearby may be the gold standard for detecting fish populations, but it’s not much fun for the trout. Scientists have found that sampling stream water for evidence of the presence of various species using environmental DNA, known as eDNA, can be more accurate than electrofishing, without disrupting the fish.

California harbor porpoises rebound after coastal gillnetting stopped

Harbor porpoises have rebounded in a big way off California. Their populations have recovered dramatically since the end of state set-gillnet fisheries that years ago entangled and killed them in the nearshore waters they frequent. These coastal set-gillnet fisheries are distinct from federally-managed offshore drift-gillnet fisheries. They have been prohibited in inshore state waters for more than a decade. The new research indicates that the coastal set gillnets had taken a greater toll on harbor porpoise than previously realized.
