Locations of leks within Eureka County, NV, USA. The study area varies across the landscape in both (a) topology and (b) habitat resistance. The habitat resistance surface was derived from the inverse of a sage-grouse nest selection model [73] and included the following variables (and direction of effect): 1) nest site elevation (−); 2) slope (+); 3) slope * elevation (−); 4) amount of habitat classified as sagebrush with 1000 m (+); 5) distance from nearest lek (−); 6) amount of habitat classified as sagebrush * distance to lek (−); 7) amount of habitat classified as pinyon-juniper woodlands (+); 8) amount of habitat classified as pinyon-juniper woodlands² (−); 9) distance from nearest water source (−); and 10) distance from nearest water source² (−). Warm colors are indicative of areas dominated by sagebrush or other shrubs, while cool colors are indicative of playas, pinyon-juniper woodlands, exotic grasslands, and pivot agricultural fields. The legend is ordered from highest to lowest latitude, with the number of individual sage-grouse sampled at each lek listed parenthetically. Leks within the same lek complex share the same color (North Cortez = orange; Cortez = red; Pine Valley = purple; Pony Express = Green; Kobeh Valley = blue)
