From the abstract:
A new species of the genus Pacificabathynella Schminke and Noodt, 1988 is described from groundwaters of Alaska (USA). This is the first record of Bathynellacea Chappuis, 1915 from the far north of America.
These were from the Kwethluk River (60.34520N, 161.089146W) on the Yukon Delta National Wildlife Refuge.

Global climate models from Germany (green), Canada (red) and USA (black) scaled to the Kenai predict that post-2030 mean summer temperatures will always be above the threshold for spruce bark beetle outbreaks. Observed temperatures are from the Homer airport since 1932. Lower bar graph shows annual beetle-kill for southern Kenai since aerial surveys began in 1971 (US Forest Service). Ed Berg graphic.
