Fig. 8. Changes in O2 consumption/transport ratio with
PO2 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. Values are means ± s.e.m.
(N
7). Significance is assumed at the level of P<0.05:
asignificant difference from control animals at same
PO2; bsignificant difference from
the same animal at preceding PO2;
csignificant difference from the same animals at 20 kPa
O2.
