- 摘要：
- gy is 28-46% less than flying between patches. We suggest such alternative movement strategies are habitat-specific, but likely to be far more widespread tha

- 摘要：
- in southern California where predatory sea otters have been extirpated, top-down control of sea urchins by alternative predators has been hypothesized but rarely teste

- 摘要：
- on strengthens top-down control on urchins, affecting the resilience of alternative reef states by reinforcing kelp forests and eroding urchin barrens. We reveal
