rTPC (version 1.0.4)

chlorella_tpc: Example metabolic thermal performance curves

Description

A dataset containing example data of rates of photosynthesis and respiration of the phytoplankton Chlorella vulgaris. Instantaneous rates of metabolism were made across a range of assay temperatures to incorporate the entire thermal performance of the populations. The dataset is the cleaned version so some datapoints have been omitted.

Usage

data("chlorella_tpc")

Format

A data frame with 649 rows and 7 variables:

curve_id

a unique value for each separate curve

growth_temp

the growth temperature that the culture was maintained at before measurements were taken (degrees centigrade)

process

whether the cultures had been kept for a long time at their growth temperature (adaptation/~100 generations) or a short time (a measure of acclimation/~10 generations)

flux

whether the curve depicts respiration or gross photosynthesis

temp

the assay temperature at which the metabolic rate was measured (degrees centigrade)

rate

the metabolic rate measured (micro mol O2 micro gram C-1 hr-1)
