Fig. 1. Lethal time to 50% mortality (LT50) for embryos of A.
limnaeus exposed to anoxic conditions at 25°C. Filled bars represent
early development through diapause II (days post-fertilization; d.p.f.). Open
bars represent post-diapause II development (days post-diapause II; d.p.d.).
Values are means ± s.e.m. (N=3). Bars with different letters
are statistically different (StudentNeumanKeul's
post-hoc test, P<0.05).
