calculate_de {ectotemp}

Calculate thermal quality of the habitat

Description

This function calculates the thermal quality of the habitat (de) from the perspective of the focal species or population as described by Hertz et al. (1993). Descriptive statistics are automatically computed as well.

Usage

calculate_de(te, tset_low, tset_up)

Arguments

te

A vector containing operative temperatures.

tset_low

Lower boundary of a species or population set-point range that was determined through thermal preference trials in a temperature gradient.

tset_up

Upper boundary of the set-point range.

Value

Thermal quality of the habitat (de) and associated descriptive statistics.
