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 effects in a simplified food web including coyotes and sage-grouse. There is very little evidence to suggest that coyotes have much of a direct negative effect on sage-grouse, but there is considerable evidence supporting direct interactions that would lead to positive indirect effects between coyotes and sage-grouse. The three...
Wolf, Canis lupus, recolonization of the Greater Yellowstone Ecosystem provides a rare opportunity to identify behaviours facilitating coexistence between sympatric canids. We investigated interactions between coyotes, Canis latrans, and recolonizing wolves at ungulate carcasses in Montana's Madison Range. We used a field-experimental study design consisting of a two-level carcass treatment (wolf presence, wolf absence) to assess factors influencing coyote risk assessment, carrion consumption and aggressive encounters with wolves. Socially dominant coyotes (alphas and betas) responded to wolf presence by increasing the proportion of time spent vigilant while scavenging. Vigilance behaviour was more pronounced when...
SiMPL Wildlife Magnet Project is a project within the AMMonitor community, which features projects that monitor wildlife and ecosystems with remotely deployed monitoring devices. Devices that capture media typically include trail cameras (photos, video) and/or autonomous recording units (audio). As with all AMMonitor projects, SiMPL Wildlife Magnet Project utilizes an AMMonitor SQLite database to track wildlife monitoring data in a standardized format, permitting cross-project collaboration. The monitoring data are released to the public in "volumes". Releases include the raw media files and their metadata, including the date, time, and location of media capture. Additional attachments at the volume level include...
