Discussion

Observational analysis reveals marine resources strengthen predation in tundra ecosystems, suggesting vulnerabilities due to climate change.

Marine resources enhance predator populations, increasing predation on Canada goose nests by Arctic foxes during low rodent abundance.
Arctic fox abundance is tied to polar bear body condition, revealing multiple ecosystem linkages across tundra and sea ice.
Environmental conditions, particularly snow persistence, significantly impact rodent numbers, affecting predator dynamics in tundra ecosystems.
Trends indicate a phenological mismatch for Canada geese, emphasizing the effects of climate change on reproductive success correlated with predator dynamics.

Johnson‐Bice et al. (2025) studied this question.
