Herbicide phytotoxicity dataset from Jones & Kerswell (2003).

Format

An object of class data.frame with 580 rows and 3 columns.

Details

The response data (Fv/Fm) Chlorophyll fluorescence measurements of symbiotic dinoflagellates still in the host tissue of the coral (in hospite or in vivo) were measured using a DIVING-PAM chlorophyll fluorometer (Walz) on vertical planes of tissue 2 to 3 cm above the base of the corals, using either a 6 mm (Acropora formosa) or 2 mm (Seriatopora hystrix) fibre-optic probe. Parameters measured were the maximum potential quantum yield (Fv/Fm).

Additional information on each of the herbicides included is available from the original publication Jones & Kerswell (2003).

The columns are as follows:

herbicide

The herbicide (chr).

concentration

The treatment concentration in µg / L (dbl).

fvfm

Maximum effective quantum yield (dbl).
