lamprey_time: Lethal time data for seasonal exposure to TFM for larval sea lamprey

Description

This dataset contains the amount of responding/dead lamprey from 1 to 12 h of exposure to the piscicide, 3-trifluoromethyl-4-nitrophenol (TFM), for the calculated LC50s at each month for the 2011 seasonal larval sea lamprey TFM toxicity data.

Usage

lamprey_time

Arguments

Format

A tibble containing 44 rows and 7 columns.

nominal.dose

nominal TFM dose(mg/L)

dose

averaged measured TFM dose (mg/L) over 12 h of exposures

month

month in which toxicity test occurred

hour

duration of exposure in hours

response

number of lamprey that responded over 12 h exposure to TFM

survive

number of lamprey that survived over 12 h exposure to TFM

total

total number of lamprey that were exposed to TFM over 12 h

Details

For each month, new lamprey were collected from the deer creek, MI, and were randomly assigned to a tank for exposure to the piscicide, 3-trifluoromethyl-4-nitrophenol (TFM). The LC50 at each month was then calculated and the amount of responding/dead lamprey from 1 to 12 h was recorded.
