What critical variable did a complex modeling study suggest is universally shared and critical for biome distribution predictors, alongside annual averages?

Answer

Mean diurnal range (BIO2)

One complex modeling study found that the mean diurnal range (BIO2)—the average difference between daily maximum and minimum temperatures—was a universally shared, critical variable in predictive models.
