Climate change has led to sightings of species like the European adder, spiders, and herons beyond their typical range in the Russian Arctic.
Common garter snakes are no longer rare in southwestern Newfoundland, and researchers are conducting genetic work to determine their origin.
The earliest I have ever seen the cormorant snake has been around the first week of April. I could never imagine meeting snakes in January.
Participants in the expedition of the institutes of the Russian Academy of Sciences “Clean Arctic - East - 77” reported the appearance of more southern species of spiders and birds in the Arctic Circle. The unevenness of their appearance at the same geographic latitude showed that the northern border of their ranges did not shift along the entire length, but formed several protrusions in the northern direction in the form of petals. "Petal thawing” referrs to the emergence of zones with a width of 50 to 200 kilometers at the southern base where permafrost is thawing.
