Fig 3
Body size distribution pattern.
Autumn and spring body size distribution in the Sandågrotta Cave, and the surface populations of Lake Lille Lauarvann and Lake Ulvenvann. The color codes are as follows; white bars = immature individuals, ligth green bars = females and dark green = males. The vertical scale denotes the probability of finding different size-classes within these population. The sample size for each site and temporal comparison is given within each of the six figures.
