Figure 2. Mean developmental rate for embryos on exposure to stressors.

Effects of temperature, pH, and spectral treatments on developmental rate of a) Bembicium nanum (n = 8) and b) Dolabrifera brazieri (n = 6). Developmental stages were classified as (1) nonciliated (pre-trochophore or undeveloped eggs), (2) ciliated with no shell (trochophore/early veliger), (3) partial shell (veliger), and (4) full shell (late veliger/larva). Error bars are standard error of mean.
