Key Points

To examine how variation across a natural dissolved oxygen gradient influences the thermal tolerance and behavioral stress thresholds of an East African fish species.
Monitored fish behavioral responses and thermal agitation thresholds across aquatic environments with varying dissolved oxygen levels.
Evaluated physiological tolerance limits within natural stream and swamp habitats prone to seasonal dry periods and hypoxia.
Fish exposed to lower dissolved oxygen conditions became agitated and exhibited signs of thermal stress at significantly lower water temperatures.
Hypoxic conditions reduced the overall thermal safety margin of the fish, highlighting vulnerability to population decline during dry-season hypoxic events.

Implication

Ecological study reveals reduced thermal tolerance under hypoxia in East African fish, suggesting heightened extinction risk during seasonal dry periods.
