briere2_99: Briere et al equation 2 of development rate as a function of temperature.
Description
Briere, J.F., Pracros, P., le Roux, A.Y. and Pierre, S. (1999) A novel rate model of
temperature-dependent development for arthropods. Environmental Entomology, 28, 22-29.
Equation:
rT ~ aa * T * (T - Tmin) * (Tmax - T)^(1 / bb)
where rT is the development rate, T the temperature, Tmin the low
temperature developmental threshold, Tmax the lethal temperature, and aa and
bb empirical constants.
