Salmon are disappearing on the Yukon and Kuskokwim. Here’s what to know about the crisis this summer.
Chinook (king) and chum are the major salmon species on the Yukon and Kuskokwim. They’ve been at historically low numbers in both rivers for years. The coho (silver) returns have also dropped.This will be the fourth year subsistence fishing has been closed or severely restricted on both rivers. The region is bracing for another dismal subsistence harvest.

Ancient Indigenous 'clam gardens' could be modern-day climate solution
For close to four millennia, "clam gardens" on beaches on the west coast of B.C. have provided First Nations with a supply of not just clams but other types of seafood. Scientific experimentation by researchers from Simon Fraser University, in collaboration with Coastal Salish First Nations, indicates clam gardens help sea life stay cooler. The research aims to show how ancient Indigenous practices offer a modern-day solution to coping with climate change.

Millions breathing hazardous air as smoke from Canadian wildfires streams south over US
The air quality index, a U.S. Environmental Protection Agency metric for air pollution, exceeded a staggering 400 at times in Syracuse, New York City and Pennsylvania’s Lehigh Valley. A level of 50 or under is considered good; anything over 300 is considered “hazardous,” when even healthy people are advised to curtail outdoor physical activity.

A large fish that fills freezers in Northwest Alaska could be in danger
Following a thaw slump, the water becomes cloudy and full of sediment, potentially suffocating the eggs of spawning sheefish. Scientists are concerned that permafrost thaw could lead to declines in the sheefish population, a staple food for many Alaskans.

Tiny but tenacious: arctic-alpine plants are engineers and warning bells
When most people consider the arctic, or high-altitude mountain landscapes, they think of endless snow, ice and bare rock. But pastel-coloured flowers, sometimes just a few millimetres wide, bloom in these dramatic places too. The miniature flowers not only weather some of the toughest habitats on Earth, but can also help engineer the landscape for other species.

As Arctic warms, female arctic ground squirrels end hibernation before males – a mismatch with consequences
As Alaskan permafrost warms, hibernating arctic ground squirrels generate less heat, causing females to emerge from hibernation up to 10 days before their male counterparts – a mismatch that could have large, cascading ecological impacts. While reduced thermogenesis due to warming temperatures could allow the squirrels to conserve energy and, thus, increase winter survival, a shortened hibernation season could also increase the exposure of the animals to hungry predators, altering mortality rates, particularly for earlier emerging female squirrels. The phenological mismatch between the sexes may also disrupt reproductive rates. And over longer time scales, continued warming in the Arctic may lead to changes in male squirrel seasonal behaviors, say the authors.

Orcas have sunk 3 boats in Europe and appear to be teaching others to do the same. But why?
Scientists think a traumatized orca initiated the assault on boats after a "critical moment of agony" and that the behavior is spreading among the population through social learning.
