Highly venomous spiders native to Chile remain a worry for workers at a firm in Sandviken, near Gävle, several years after they were first discovered.
Spiders possibly wolf spiders of family (Lycosidae) numbering some 75 to 100 were seen on top of snow along Boulder Creek road and lagoon.
Warmer temperatures in the Arctic may lead to more, and larger, wolf spiders. But this might be good for the region, according to a new study released in the journal Proceeding of the National Academy of Sciences.
Climate change leads to longer growing seasons in the Arctic. A new study shows that predators like wolf spiders respond to the changing conditions and have been able to produce two clutches of offspring during the short Arctic summer. The greater number of spiders may influence the food chains in Greenland.
