Spatial Heterogeneity in Response of Male Greater Sage-Grouse Lek Attendance to Energy Development
Landscape modification due to rapidly expanding energy development, in particular oil and gas, in the westernUSA, have prompted concerns over how such developments may impact wildlife. One species of conservation concern across much of the Intermountain West is the greater sage-grouse (Centrocercusurophasianus). Sage-grouse have been petitioned for listing under provisions of the Endangered Spe...
متن کاملDisturbance Factors Influencing Greater Sage-Grouse Lek Abandonment in North-Central Wyoming
Detecting the disappearance of active leks is the most efficient way to determine large declines in greater sage-grouse (Centrocercus urophasianus) populations; thus, understanding factors that influence lek abandonment is critical. We evaluated factors that may have influenced the probability of sage-grouse lek abandonment in the Bighorn Basin (BHB) of north-central Wyoming from 1980 to 2009. ...
متن کاملLek Organization in Sage Grouse: Variations on a Territorial Theme
-During a 5-year study of Sage Grouse (Centrocercus urophasianus) in eastern California, displaying males abandoned territoriality throughout one breeding season and did so intermittently in three others. Abandonment followed a severe winter and was correlated with a change from location-dependent to hierarchical dominance relationships between males. Intermittent territorial breakdowns occurre...
متن کاملWest Nile virus and greater sage-grouse: estimating infection rate in a wild bird population.
Understanding impacts of disease on wild bird populations requires knowing not only mortality rate following infection, but also the proportion of the population that is infected. Greater sage-grouse (Centrocercus urophasianus) in western North America are known to have a high mortality rate following infection with West Nile virus (WNv), but actual infection rates in wild populations remain un...
متن کاملSage-Grouse and Indirect Interactions: Potential Implications of Coyote Control on Sage-Grouse Populations
Coyotes (Canis latrans) are lethally controlled throughout the range of Greater Sage-Grouse (Centrocercus urophasianus) and it has been suggested that such control may benefit sage-grouse. However, the perceived benefits of control are based on the direct effects of coyotes on sage-grouse and largely ignore potential indirect interactions. Here, we summarize some of the evidence for direct effe...
