Southern right whale (Eubalaena australis) reproductive success is influenced by krill (Euphausia superba) density and climate
. The number of calves recorded each year varied from 7 to 43 (x = 21.11 ± 11.88). Using cross-correlation ... correlations were found with krill densities (r = 0.69, p = 0.002, lag 0 years), Oceanic Niño Index (r = −0.65 ... , p = 0.03, lag 6 years), Antarctic Oscillation (r = 0.76, p = 0.01, lag 7 years) and Antarctic sea ice area ... (r = −0.68, p = 0.002, lag 0 years). Our results suggest that global climate indices influence southern right ...
