This issue is to keep track of decisions regarding whether to include a polynomial term in models for individual climate variables.
MAT: ANPP shows a polynomial term; however deltaAIC for this model + linear model is <2, so no strong support for polynomial. I suggest we run all MAT models as a linear term.
TempSeasonality/TempRangeAnnual: several fluxes fit to a polynomial term; where models are polynomial there is strong support for this. I suggest we keep the polynomial term in these models where applicable.
latitude: ANPP + R_root fit to polynomial terms, but there is no strong support for this based on the AIC values (deltaAIC <2). GPP also fits - there is slightly stronger support (deltaAIC = 2.46, but unless we have a strong reason to want to present this, I suggest we run all models as linear.
We have good reason to include a polynomial term in models for precipitation.
