Animals may fall into what are called evolutionary and ecological traps when they make poor decisions using seemingly reliable environmental cues. For example, animals may select habitats to occupy based on food availability, but mortality may be highest in habitats with the highest food availability. A new Mammal Review article examines how the brown (grizzly) bear can fall into such traps in human-modified landscapes, which may contribute to decreases in brown bear populations.
