Core Reorganization in Food Webs Buffers Ecosystems Against Warming

Icelandic stream ecosystems provide data on food web structure and function across a natural temperature gradient. The dataset, created by Pablo Augusto Poleto Antiqueira and last updated in May 2026, likely contains metrics on species abundance, energy flux, and robustness to secondary extinctions. It supports analysis of how core-periphery organization in food webs mediates ecosystem responses to warming.

Use Cases

• Modeling ecosystem robustness to species loss based on food web connectance data
• Analyzing energy flux dynamics in response to temperature changes
• Studying turnover in core species abundance and identity across a thermal gradient
• Simulating secondary extinction cascades using dynamic food web models

Strengths

• Data is derived from a natural stream temperature gradient in Iceland, providing a real-world climate analog.
• Includes multiple file formats (TXT, JPEG, R, CSV, RHISTORY) for different analysis approaches.
• Released under a permissive CC-BY-4.0 license for broad reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
