Predicted distribution of July larval COG estimates (dots coded by decade) and corresponding kernel density quantiles (a and c), and the relationship between mean July SST (°C) and July COG northings (latitudinal coordinates in km; b and d) for BSB Paralabrax nebulifer (top) and KB P. clathratus (bottom) in southern California, USA, 1963–2016. The shaded line in (d) depicts the positive linear relationship between larval KB July predicted COG northings and mean July SST, with temperature explaining 26% of the variability (glm: β = 12.061 ± 3.878 SE, R² = 0.26, P = .004).
