Figure 4From: Oceanic dispersal barriers, adaptation and larval retention: an interdisciplinary assessment of potential factors maintaining a phylogeographic break between sister lineages of an African prawnSurvival of Upogebia africana larvae. Cumulative survival (mean + SD) for successive zoeal stages of U. africana larvae of the subtropical and temperate lineages as a function of temperature. Asterisks denote a significant difference in survival of larvae from different lineages (based on a Student t-test).Back to article page
