From: Climate-driven reproductive decline in Southern right whales
Cross-correlation between mean apparent calving interval (CI) of southern right whales and environmental variables at multiple time lags. Bar plots show the strength and direction of correlation between CI and six environmental indices: Antarctic Oscillation (AAO), Oceanic Niño Index (ONI), Antarctic sea ice concentration anomaly (SIC (high), mid-latitude sea surface temperature (SST [mid]), and cumulative summer Chl concentration at mid and high latitudes (Chl [mid] and Chl [high]). Dashed orange lines represent approximate 95% confidence bounds.
