Figure 6 in Harbor seal use of glacier ice and terrestrial haul-outs in the Kenai Fjords, Alaska

Figure 6. Proportion of harbor seal pups counted during pupping relative to total seals (including pups) during pupping (Panel A) and during the subsequent molt (Panel B) at glacial ice (blue) and terrestrial (brown) haul-outs among different locations and time periods. The box (bounded by 13%–23%) represents range of the percent of pups to total seals counted at terrestrial haul-outs outside of Alaska (Venables and Venables 1955, Boulva 1975, Boulva and McLaren 1979, Brown and Mate 1983, Calambokidis et al. 1987). The vertical bar within the box represents the proportion of pups born into an increasing population in British Columbia (Bigg 1969). * designates proportions derived from mean values adjusted for standardized environmental conditions.
