Fig. 7. Hill plot of hemoglobin for tadpole shrimp reared under normoxic
(1921 kPa O2; open circles), moderately hypoxic (1013
kPa O2; gray circles) or severe hypoxic (13 kPa
O2; black circles) conditions. Maximal slope for each rearing group
represented by regression line. Cooperativities (nH) for
each group are given in Table
1. Values are means ± s.e.m. (N
7). In some
cases, the error bars were smaller than the symbols.
