... design and may be poor predictors of animal survival during heat events in the field. In intertidal mussels, cardiac thermal performance (CTP) tests have been widely used as indicators of animals' acclimation or acclimatization state, providing two indices of thermal responses: critical temperature ( T...

.... For example, suppose that two mussels with different critical temperatures (e.g. 33 versus 39°C) but the same T flat (41°C), reach a sublethal temperature of 38°C during an afternoon low tide. The mussel with a T crit of 33°C will spend considerably more time with a lower HR (and presumably lower oxygen...

... in the ribbed mussel, Mytilus californianus , comparing populations from high and low sites in the intertidal zone where emersion duration leads to different mean daily heating rates. Two temperature-related cardiac variables were examined: (1) the critical temperature ( T crit ) at which heart rate (HR...

... that oxygen safety margins set thermal limits in air-breathing invertebrates. Bombyx mori Thermolimit respirometry Critical temperature Supply and demand Oxygen- and capacity-limited thermal tolerance The mechanisms underlying thermal tolerance are central to predicting climate change...

..., and hemolymph lactate, we show that oxygen transport capacity is maintained up to the critical maximum temperature around 41°C. In M. rosenbergii heart rate and gill ventilation rate increases exponentially until immediately below critical temperatures and at 38°C animals still retained more than 76% of aerobic...
