Minimum AMBI as a linear function of salinity

Source: R/utils.R
AMBI_sal.Rd

Used by DKI2(), adjusting the AMBI index to account for decreasing species diversity with decreasing salinity.

Usage

AMBI_sal(psal, intercept = 3.083, slope = -0.111)

Arguments

psal

numeric, salinity

intercept

numeric, default 3.083

slope

numeric, default -0.111

Value

a numeric value AMBI_min

Details

AMBI_sal() and H_sal() are named, respectively, AMBI_min and H_max in the DKI documentation (Carstensen et al., 2014). They are renamed in ambiR to reflect the fact that they are functions of salinity and not minimum or maximum values from data being used.

Examples

AMBI_sal(20.1)
