Fig. 2: Relationship of survival and reproductive rates and Chinook Index.
From: Warning sign of an accelerating decline in critically endangered killer whales (Orcinus orca)
Annual survival rates (Fig. 2a) and reproductive rates (the proportion of breeding age females producing a calf) (Fig. 2b) for SRKW of different age-sex classes (Table 1) predicted from logistic regressions against the Chinook salmon prey abundance. Calf survival is in yellow, post-reproductive female is in red, older male is in green, older female is in orange, subadult survival is in dark blue, young female is in light blue, and young male is in blue.
