Fig. 4 (a, b, c). Plots of species abundance data against estimated warm, distance-weighted temperatures (DC) for
all samples in the four cores. Each plot shows generally two groups of points representing temperature differences
between the Rio Grande Rise cores (18-24 DC) and the tropical cores (26-28 D C). Only species showing a trend
toward cool- or warm-temperature preferences are included.
