Impact of heating rate on cardiac thermal tolerance in the California mussel, Mytilus californianus

Description of this data

In this study we sought to determine whether heating rate affects cardiac thermal tolerance in the
often-studied and ecologically important mussel M. californianus. We compared mussels living at high and low intertidal heights to determine whether heating rate differentially affected cardiac thermal tolerance in animals acclimatized to different exposure conditions.

The three csv files comprise the data needed to replicate the study findings (figures and statistical analyses). The morphometric, Tcrit, and FLT data are in one file; the HR vs. mussel body temperature data for the time series analysis are in another file (for each 15 minutes of HR and temperature data recorded throughout trials)- and the slopes of the HR vs. temperature data (up until Tcrit) can be calculated for each individual from these data; last, the HR Summary Data file contains the HR data (minimum, maximum, Q10, total change in HR, and baseline HR data).

The mussel ID column is the unique mussel ID we gave mussels. The air heating rate is our notation for one of the three trials mussels were tested at: 3 = slow heating rate; 5 = moderate heating rate; and 8 = fast heating rate. Zone indicates the zone that the mussel came from (high or low zone). Last, the "Mussel Heating Rate" is the individually calculated mussel heating rate. Note that for some analyses all mussels (n = 70) are included, and for other analyses (when comparing heating rate trials), 4 animals are excluded (n = 66 total). See Statistical Analyses section for further details.
