Domain-specific¶
- Allen's Rule
- is the ecogeographic generalization that endothermic vertebrates — birds and mammals — from colder climates tend to have shorter and more compact peripheral appendages relative to body size than conspecifics or close relatives from warmer climates
This sourceStates Allen's rule as smaller endotherm appendages relative to body size in colder climates for heat conservation, and reports clinal support across 214 bird species.

Verification¶
Does it exist? Not checked yet. This work's DOI is recorded above but has not been resolved against an external catalogue, so nothing here confirms the work exists.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
