Extended Data Fig. 4: Sea surface temperature (SST) anomalies with domoic acid (DA) concentrations.
From: Bowhead whale faeces link increasing algal toxins in the Arctic to ocean warming
Spearman rank correlation results comparing domoic acid (DA) concentrations in bowhead feces (ng/g; n = 205) with July sea surface temperature (SST) anomalies. DA concentrations in feces were the most strongly correlated with July summer SST anomalies (rho = 0.35, P = 2.9 e-07, Figure below). DA was also positively and significantly correlated with June (rho = 0.17, P = 0.016), August (rho=0.28, P = 6.2 e-05), and September (rho = 0.25, P = 2.7 e-4) SST anomalies. Saxitoxin (STX) concentrations in bowhead feces were not significantly correlated with SST anomalies (June; rho = 0.13, P = 0.071, July; rho = 0.11, P = 0.13, August; rho = 0.08, P = 0.24, and September; rho = 0.04, P = 0.58).
