Hypothesis
High-human activity was displacing predators and thus indirectly creating spatial refuge for prey species.
Conclusion
High-human activity displaces predators, allowing prey species to thrive in areas with more human presence.
Supporting Evidence
- Prey species were three times more abundant on roads and trails with more than 32 humans per day.
- Predators were less abundant on roads and trails that exceeded 18 humans per day.
- Humans co-occurred with prey species more than with predator species at camera sites.
Takeaway
When there are a lot of people around, predators stay away, which helps prey animals feel safer and live better.
Methodology
The study used camera traps to measure the occurrence of large mammals and analyzed species co-occurrence and the influence of human activity on predator and prey counts.
Potential Biases
The sampling method may have missed areas with particularly high or low predator or prey densities.
Limitations
The study only measured species occurrence during the summer and did not account for potential changes in behavior during winter.
Participant Demographics
The study focused on large mammal species in southwest Alberta, Canada.
