Earlier springs enable High-Arctic wolf spiders to produce a second clutch - supplementary data

Toke T. Høye, Jean-Claude Kresse, Amanda M. Koltz & Joseph J. Bowden
Spiders at southern latitudes commonly produce multiple clutches, but this has not been observed at high latitudes where activity seasons are much shorter. Yet the timing of snowmelt is advancing in the Arctic, which may allow some species to produce an additional clutch. To determine if this is already happening, we used specimens of the wolf spider Pardosa glacialis caught by pitfall traps from the long-term (1996-2014) monitoring program at Zackenberg, Northeast Greenland. We dissected...
