Rebecca K. McKee, Kristen Hart, Spencer Zeitoune, Robert A. McCleery
2025, Journal of Animal Ecology (94) 210-219
1. Invasive predators pose a substantial threat to global biodiversity. Native prey species frequently exhibit naïveté to the cues of invasive predators, and this phenomenon may contribute to the disproportionate impact of invasive predators on prey populations. However, not all species exhibit naïveté, which has led to the generation of...

2025, Book chapter, Tectonics and seismic structure of Alaska and northwestern Canada: EarthScope and beyond
Tectonic tremor is a semicontinuous, low-frequency seismic signal associated with stable fault motion at major plate boundaries worldwide. In subduction zones, tremor often coincides with geodetic transients that indicate discrete slow slip on the subducting plate interface. Because tremor epicenters offer better spatial and temporal resolution than geodetic inversions of...
