It remains to be investigated what the trophic consequences of such patterns are in a global warming context. Our study provides evidence that bivoltinism could be a more widespread pattern than expected in Arctic wolf spiders. We argue that information about the embryonic stage can be critical for evaluating evidence of wolf spider populations producing more than one clutch in a season. We also observed significantly larger first than second clutches. hyperborea, we were able to show that both species can produce a second clutch over the active season by using information on the embryonic stages. Whilst a bimodal pattern in the clutch size frequency distribution was only revealed for P. This phenomenon could be widespread in northern latitudes, and here we investigated the voltinism of two other very abundant species of wolf spiders in the Low-Arctic, Pardosa hyperborea (Thorell 1872) and Pardosa furcifera (Thorell 1875), over the period 2015–2017. For instance in arthropods, it was recently shown that females of the spider species Pardosa glacialis (Thorell 1872) (Lycosidae) are able to produce two clutches within one growing season in years when snowmelt occurs particularly early. "These changes in the life history have not been seen earlier and evidence suggests that the phenomenon plays an important role for Arctic insects and spiders.Changing abiotic conditions can affect the phenology of animals and plants with implications for their reproductive output, especially in rapidly changing regions like the Arctic. Høye from the Arctic Research Centre and Department of Bioscience at Aarhus University in a statement. The large amount of data allows us to show how small animals in the Arctic change their life history in response to climate change," said Toke T. "We now have the longest time series of spiders collected in the Arctic. The snow disappears earlier and earlier from the Arctic tundra and climate change therefore entails a longer growth season for Arctic plants and animals. Toke T. It soon became apparent that the spiders captured in the short Arctic summer were carting around two egg sacs, a behavior that’s common in warmer places but had never been seen before in the Arctic. The teams were able to count the number of eggs in the sacs of captured wolf spiders and see how these compared depending on which season they were found. Estimating the clutch counts of wolf spiders is reasonably simple, since they carry their eggs around in a little sac.
