Predators affect prey by killing them directly (lethal effects) and by inducing costly
antipredator behaviours in living prey (risk effects). Risk effects can strongly influence prey …

Partial migration, a phenomenon wherein only some individuals within a population migrate,
is taxonomically widespread. While well-studied in birds and fish, partial migration in large …

Great leaps forward in scientific understanding are often spurred by innovations in
technology. The explosion of miniature sensors that are driving the boom in consumer …

Sea otters (Enhydra lutris) and wolves (Canis lupus) are two apex predators with strong and
cascading effects on ecosystem structure and function. After decades of recovery from near …

Each spring, migratory herbivores around the world track or 'surf'green waves of newly
emergent vegetation to distant summer or wet‐season ranges. This foraging tactic may help …

Migratory animals are predicted to enhance lifetime fitness by obtaining higher quality
forage and/or reducing predation risk compared to non‐migratory conspecifics. Despite …

The migratory movements of wild animals can promote abundance and support ecosystem
functioning. For large herbivores, mounting evidence suggests that migratory behaviour is …

Migratory ungulates are thought to be declining globally because their dependence on large
landscapes renders them highly vulnerable to environmental change. Yet recent studies …

Decomposing variation in juvenile recruitment is a key component of understanding
population dynamics for partially migratory ungulates. We investigated reproductive …

Although ungulates are the main prey of wolves (Canis lupus) throughout their range,
substantial dietary diversity may allow wolves to persist even when ungulates are declining …
