Description: |
The prevalence of hypoxic (low oxygen) areas in coastal waters is predicted to increase in the future, both in terms of their scale and duration. And while the adults of many estuarine invertebrates can cope with short periods of hypoxia, it has previously been unclear whether that ability is present if animals are bred and reared under chronic hypoxia. A new study shows that exposure to even moderate hypoxia can have markedly different effects on metabolic performance, depending on whether adults are exposed to short-term hypoxia or undergo the whole of their development under hypoxic conditions.[Source: University of Plymouth]
