Oxygen radical formation was directly dependent on temperature-controlled respiration rates in states 3 and 4 and inversely related to mitochondrial coupling (RCR+) in state 4 and is therefore involved in cellular heat stress in this eurythermal marine ectotherm.

Data suggest that PPARs and UCPs are involved in the alterations observed in zebrafish brain after exposure to 18°C, and stimulation of the PPAR-UCP axis may help to prevent oxidative damage and to maintain metabolic balance and cellular homeostasis in the brains of ectothermic zebra fish upon cold exposure.

There is a consistent positive correlation between rates of ROS formation and antioxidant levels among most animals examined so far for these traits, and the consensus of these studies is that ROS and antioxidants levels are inversely related to MLSP.
Climate change and glacier retreat drive shifts in an Antarctic benthic ecosystem
A marked shift in an Antarctic benthic community that can be linked to ongoing climate change is reported, and the resulting increased sediment runoff, triggered by glacier retreat, is highlighted as the potential causal factor.

In a recovery-time series, heat-induced hypoxia and subsequent reoxygenation upon return of the fishes to 12°C led to increased protein oxidation and chemiluminescence rates within the first 12 h of recovery, resembling ischemia/reperfusion injury in mammals.

The comparison between mitochondria from oxyregulating and oxyconforming organisms supports the existence of an alternative oxidase in addition to the classical cytochrome c oxidase, thought to be adaptive in confined, usually hypoxic environments.
