Global Climate Connectivity Projections for Terrestrial Vertebrates Under Warming

Functional effectiveness of climate connectivity (FECC) metric quantifies how climate corridors link suitable habitats for biological communities under global warming. Projections show 77.9% of global land area may experience declining FECC with warming exceeding 4°C during 2061–2080, restricting species' accessible ranges. The dataset was created by Zhaoning Wu and published in April 2026.

Use Cases

• Identify regions vulnerable to connectivity erosion by mapping projected FECC decline values across the global land area.
• Model potential ecological isolation risks by analyzing the relationship between FECC metrics and warming scenarios exceeding 4°C.
• Prioritize conservation corridors by assessing FECC contributions for linking discrete suitable habitats for specific biological communities.
• Forecast accessible range shifts for terrestrial vertebrates using FECC projections for the 2061–2080 period.

Strengths

• Covers 77.9% of global land area in its analysis of connectivity decline.
• Provides projections for a specific future time period (2061–2080).
• Dataset size of 127.4 MB indicates detailed spatial data.

Limitations

• Underlying species occurrence or community data used to derive FECC metric is not included.
• Projections are model-dependent and subject to uncertainties in climate and ecological modeling.
• Actual row/column counts and granularity of spatial data are unknown.
