Description

Detailed methods are presented in Sasaki & Dam 2019 (DOI: 10.1111/gcb.14811). Copepods were collected from ten locations across the Northwest Atlantic (recorded in the Population column). Populations were maintained at the UConn Avery Point campus for three generations at 18oC, with a 12:12 light:dark cycle and a diet of Tetrasemis sp., Thalassiosira weissflogii, and Rhodomonas salina.

Methods & Sampling

F3 generation eggs were collected and split into two groups, which developed at either 18oC or 22oC (recorded in the Dev_temp column). Once mature, healthy females were exposed to a 24-hour acute heat shock, after which individual survivorship was recorded using a dissection microscope (recorded in the Survivorship column). Each female experienced only a single temperature during the heat shock (recorded in the Stress_temp column).

Data Processing Description

Data was not processed before analyses. All analyses were performed with the raw data in R version 3.0. Survivorship curves were estimated using a logistic regression (glm function from the stats package). Thermal tolerance was estimated from the survivorship curves with the dose.p function (MASS package). Correlations were performed using linear regressions (lm function from the stats package).

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- added Latitude, Longitude, and Collection_Date columns
