Most ecosystems have multiple predator species that not only compete for shared prey, but
also pose direct threats to each other. These intraguild interactions are key drivers of …

Predators may influence their prey populations not only through direct lethal effects, but also
through indirect behavioral changes. Here, we combined spatiotemporal fine‐scale data …
