AIC Table for Steller's Eider Population Models on the Arctic Coastal Plain

Model selection statistics for spatio-temporal generalized additive models fitted to Steller's eider survey data. The dataset, authored by Erik E. Osnas, was last updated on April 30, 2026. It supports analysis of population fluctuations and density mapping for this threatened Alaska-breeding bird species.

Use Cases

• Compare model fits for Steller's eider population estimates based on AIC values.
• Assess the precision of model-based versus design-based population estimates as described in the study.
• Investigate the reported 6.53-year population cycle and its confidence intervals.
• Support spatial density mapping for conservation planning in the Arctic Coastal Plain and Utqiagvik Triangle areas.

Strengths

• Model outputs are associated with a detailed ecological study published on figshare.
• The dataset is licensed under CC-BY-4.0, permitting open sharing and adaptation.
• File size is 5.5 KB, indicating a focused and manageable data table.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a small, 5.5 KB model output table, not the primary survey data.
