Additionally, predator-prey relationships in birds have been modified around loud well pads with compressors and greater sage grouse Centrocercus
urophasianus males were found in lower abundances at lek sites exposed to chronic and intermittent noise disturbances associated with natural gas production than elsewhere (Francis et al.
Phenotypic divergence of secondary sexual traits among sage grouse, Centrocercus
Butterflies are of conservation interest as bioindicators (Hammond and McCorkle 1984, New 1997), pollinators (Ehrlich 2003), prey for other species (Guppy and Shepard 2001) including Greater Sage-Grouse, Centrocercus
urophasianus (Bonaparte), (Gregg 2006), and as charismatic conservation taxa.
