Whale entanglements disentangled through the lens of cumulative habitat compression
Fig 4
Correlations between reported whale entanglements and habitat compression.
(A) Spearman correlations between monthly cumulative HCI (cHCI) and the annual humpback whale entanglement record (detrended). (B) Spearman correlations between monthly cHCI and residuals derived from the entanglement and population abundance time series (see Fig 2). Negative correlations indicate more entanglements during periods of low cHCI. All correlations are significant, p < 0.001 (see S1 and S2 Tables and S1 Text and S2 Text for bootstrapping results). See Fig 1 for regional biogeographic boundaries.
