Alaska's wolves unpredictably devoured all the deer, performing an unprecedented act.
In 2013, a new chapter began on Pleasant Island, Alaska, as wolves colonized the previously uninhabited land. This marked the start of a significant shift in the island's ecosystem, particularly in the predator-prey dynamics between wolves and sea otters.
Initially, wolves relied on large terrestrial prey such as deer. However, a rapid decline in the deer population followed the wolves' arrival, leading to a change in the wolves' dietary habits. By 2015, sea otters became a dominant part of the wolves' diet, making up over 80% of their food intake.
This change in diet is noteworthy as sea otters are a top predator in the near-shore ecosystem, while wolves are an apex predator in the terrestrial area. The shift is attributed to the vulnerability of sea otters during low tide when they rest on land or in shallow waters, making them easy targets for wolves.
The interaction between sea otters and terrestrial predators like wolves has had profound effects on Pleasant Island's ecosystem. Studies conducted by the Alaska Department of Fish and Game and Oregon State University researchers have confirmed this shift and its consequences.
The predation pressure by wolves on sea otters has raised important ecological questions, especially as sea otters have been recovering due to conservation efforts. However, this new dynamic has also added a factor influencing sea otter populations locally on Pleasant Island.
Moreover, studies have revealed high mercury levels in wolves feeding on sea otters, suggesting bioaccumulation of toxins through the marine food chain. This has implications for wolf health and ecosystem contamination pathways.
The pattern held through to 2020, when the study ended. As the wolves continue to thrive on Pleasant Island, researchers are investigating the impact of terrestrial predators on sea otters and how sea otters may be an abundant marine prey to terrestrial predators.
