Description

Detailed methods are presented in Sasaki et al. 2019 (DOI: 10.1098/rsos.182115). Copepods were collected from two locations across the Northwest Atlantic (recorded in the Pop column). Populations were maintained at the UConn Avery Point campus for over three generations at 18oC, with a 12:12 light:dark cycle and a diet of Tetrasemis sp., Thalassiosira weissflogii, and Rhodomonas salina.

Methods & Sampling

At the beginning of the experiment, eggs were collected and split into two groups, which developed at either 18oC or 22oC (recorded in the Dev column). Once mature, body size measurements were made for healthy males and females (recorded in the Sex column) from the laboratory cultures. Individuals were isolated in a drop of filtered seawater and photographed using a camera attached to an inverted microscope after the water had been removed.

Data Processing Description

Body lengths were measured from images as the length of the prosome using Image-J (https://imagej.nih.gov/ij/). All subsequent analyses were performed in R version 3.0.

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
