Sets of variables considered as predictors in models.

N-mixture models included explanatory variables estimating initial abundance (Λ) were lek specific and related to 1995 (except Λ for Never1996 was related to 1996). Models with density-dependent dynamics (Gompertz or Ricker models) included time-varying variables predicting instantaneous growth rate (r) and equilibrium abundance (K). Whereas, models with exponential growth dynamics included time-varying variables predicting maximum per capita rate of increase (lambda [λ]). Explanatory variables were spatially explicit to each sage-grouse lek with time-varying variables aligned temporally as near to data acquisition date as possible, 1990–2013.
