To determine the effect of introduced noise on lek attendance and strutting behavior, I played back recorded continuous and intermittent anthropogenic sounds associated with natural gas drilling and roads at leks of Greater Sage-Grouse (). For 3 breeding seasons, I monitored sage-grouse abundance ...
For instance, a quadratic relationship between lek attendance (but not fighting rate or distance to the center of the lek) and age has been reported in male black grouse37, while a concave relationship between song consistency (but not repertoire size) and age has been observed in a free-liv...

We explored the influence of predation on lek dynamics using a stochastic dynamic game model...

To examine the possible mechanism of DW production, we dissected two male and female sage-grouse; the syrinx in both sexes differed noticeably from that of the domestic fowl, and notably had two sound sources where the bronchi join the syrinx. Additionally, we found males possess a region of...
