Figure 1.

Inter-annual variation in body size of Pardosa glacialis males (black circles), females (white circles) and juveniles (triangles) given as the annual average width of the carapace in mm (±s.e.) and average timing of snowmelt in the trap plots in year_t (solid line) and year_{t −1} (dotted line). For juveniles, the average is based on individuals larger than 1.7 mm. The averages of juvenile carapace widths were added to 0.4 mm to facilitate visual comparison among groups.
