Beta Function Thermal Performance Curve

The function constructs a thermal performance curve based on a beta function (Asbury and Angilletta 2010) .

TPC_beta(T_b, shift = -1, breadth = 0.1, aran = 0, tolerance = 43, skew = 0.7)

Arguments

T_b

numeric temperature (C).

shift

numeric mode of the thermal performance curve.

breadth

numeric breadth of the thermal performance curve.

aran

numeric scale performance value. If 0, no scaling; if 1, include a thermodynamic effect on mean performance.

tolerance

numeric maximal breath (C) of the thermal performance curve.

skew

numeric skewness of the thermal performance curve (0-1).

Value

numeric performance.
