Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Projected impacts depend on habitat associations and limited dispersal assumptions; range shifts may alleviate some climate impacts while land-use threats remain critical.
Evidence for the claim as stated.

Study at a glance
- Design
- Computational / modelling — Stationary-range exposure of breeding bird maps to Millennium Ecosystem Assessment land-cover scenarios
- N
- N=8750 · 8,750 land-bird species of 9,713 total; marine/pelagic taxa excluded
- Population
- Global breeding distributions of land birds
- Outcome
- Combined climate and land-use change projects substantial range-area loss; land-use remains a major threat even if climate-driven shifts occur

These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
What two global change drivers are integrated?
climate and land-use change through the combined effects of these drivers on global land cover and explored the resulting reductions in range size and possible extinctions within the world's 8,750 terrestrial bird species.
Through what common currency are exposures combined?
combined effects of these drivers on global land cover and explored the resulting reductions in range size and possible extinctions within the world's 8,750 terrestrial bird species.
Key findings
Projected impacts depend on habitat associations and limited dispersal assumptions; range shifts may alleviate some climate impacts while land-use threats remain critical.
Methodology
Evaluated species’ exposure to climate and land-use change through combined effects on global land cover and bird habitat associations.
Limitations
Assumes persistent habitat associations and limited dispersal; finer habitat specialization may be missed by coarse land-cover classes.
