A Lemna effect study data set with multiple treatment levels

Description

Data was collected from Schmitt et al. (2013). The study observed the number of Lemna fronds during the study period of 14 days. The organisms were exposed to multiple concentrations of the sulfonyl urea herbicide metsulfuron-methyl.

Usage

schmitt2013

Format

An object of class data.frame with 56 rows and 4 columns.

Details

The number of Lemna fronds was recorded at the beginning of the experiment (t=0) and after 3, 5, 7, 10, 12, and 14 days. The exposure to metsulfuron-methyl was only present during the first seven days, which was followed by a recovery period of another seven days without exposure to the substance.

The tabular dataset consists of four columns:

• First column: time (days)

• Second column: observed number of fronds (-)

• Third column: trial id (-)

• Fourth column: metsulfuron-methyl concentration (ug/L)

An example scenario with parameters fitted to the experimental data set as conducted by Schmitt et al. is available as metsulfuron.
