Description

Phytoplankton thermal traits were estimated for diatoms (n=135), dinoflagellates (n=46), coccolithophores (n=30), and cyanobacteria (n=32). This dataset contains estimated traits and parameters presented in Thomas et al (2012) as well as those for 59 additional strains (Anderson et al, in review). Study selection followed the criteria outlined in Thomas et al (2012) and Anderson et al (in review).

Methods & Sampling

Thermal reaction norms were used to describe phytoplankton thermal responses following the equation presented in Thomas et al. (2012). For strains compiled previously, parameters for thermal reaction norms were provided (Thomas et al 2012 & 2016). For added strains, parameters were estimated using the thermal growth rates found in the related dataset, https://www.bco-dmo.org/dataset/839696, and the maximum likelihood approach described in Thomas et al. (2012) and the bbmle package in R 3.6.1 (2019).

Traits were then estimated for each strain using their respective thermal reaction norms, as outlined previously (Thomas et al. 2012 & 2016; Anderson and Rynearson, 2020). This included the thermal optima (Topt), thermal maxima (Tmax) and thermal niche width. The thermal maxima were quality controlled according to Thomas et al. (2016) to ensure validity.

Data Processing Description

BCO-DMO Processing:
- replaced "NA" with "nd" as missing data value;
- renamed fields (replaced periods with underscores);
- removed commas from "study" and "source" columns;
- replaced commas with semi-colons in the "name", "strain", and "clone" columns;
- replaced comments with codes due to length and generated file "derived_traits_comment_codes.csv";
- replaced/removed un-renderable characters from the "source" column.

Definitions/descriptions for "comment_code" columns:
Note 1 = Latitude approximate. Based on information from Jacques (1983), Fiala & Oriol (1984), & Fiala & Oriol (1990), there are 5 possible isolation locations, all along the same longitude: 48S, 54S, 58S, 60S, and 65S. In the absence of further information from the authors, I have used the median location.

Note 2= Growth rates estimated from nonlinear fitting. One value presented was measured in previous study.

Note 3 = location approximate
