Finally, body size and clutch size were strongly correlated in both species, but clutch size was not affected by habitat or elevation. prey availability or snowmelt timing) are more important in explaining body size variations. furcifera, a species likely more cold adapted, we found no body size difference between elevations, suggesting that local conditions (e.g. hyperborea, a species that has a southern distribution in Greenland, and we identified season length as a major driver of the development in this species. ![]() Secondly, we found smaller body sizes at high elevation in P. hyperborea, which was more associated with drier habitats, like shrubs. furcifera, which dominated wet habitats, like fens, and P. Using generalised linear models, we firstly showed a habitat partitioning between P. Over three consecutive years, we analysed the interacting effect of two environmental factors, habitat and elevation, on the abundance, body size, and clutch size in two common Low-Arctic invertebrate predators (Lycosidae, Araneae), Pardosa furcifera (Thorell 1875) and Pardosa hyperborea (Thorell 1872). Variation in functional traits along such gradients provide insights into the drivers of species abundance and distribution and are particularly valuable in this region currently experiencing strong climate warming. The Arctic tundra is characterised by harsh conditions and environmental gradients are especially pronounced.
