Males of many species use courtship behavior to attract mates. However, by doing so males may face the associated costs of increased energetic expenditure, reduced foraging time, and elevated predation risk. We investigated the costs of display in le

The causal basis of optimal prey-size selection was investigated experimentally using Three-spined Sticklebacks (Gasterosteus aculeatus) as predators and two size classes of Daphnia magna as prey. When offered a choice between a large and a small dap

The spectacular social courtship displays of lekking birds are thought to evolve via sexual selection, but this view does not easily explain the participation of many males that apparently fail to mate. One of several proposed solutions to this ‘le

We investigated whether male greater sage grouse, Centrocercus urophasianus, select lek locations on the basis of topographic features that affect their visibility to both conspecific females and a major avian predator, the golden eagle, Aquila chrys

We used microsatellite DNA markers to genotype chicks in 10 broods of lek-breeding sage grouse, Centrocercus urophasianus , whose mothers’ behaviour was studied by radiotracking and observing leks. Previous behavioural studies suggested that almost

Animals often make choices based on cues that provide uncertain information about the value of alternative options. To examine how this uncertainty affects sampling behaviour, western scrub-jays were studied in the field during selection of single fo

To test the hypothesis that female choice has been subject to direct selection by predators, it was investigated whether female guppies would switch their choice of mate from more to less conspicuous males after observing a potential predator. Social

Recent analyses of avian leks have come to conflicting conclusions concerning the role of male settlement on female traffic hotspots. This issue was re-examined in the sage grouse,Centrocercus urophasianus, using data on pre-nesting movements of radi
