Niche Size and Faunal Diversity

Klopfer, P. H., MacArthur, R. H.·1960·The American Naturalist

Abstract

1. As one proceeds from North Temperate regions towards the Tropics, the proportion of non-passerines in the avifauna increases. 2. The number of individuals per species for a given area decreases towards the tropics for the passerines but not for the non-passerines. 3. At all latitudes, however, non-passerines are less abundant than passerines. This is interpreted as support for the notion that the phylogenetically older non-passerines species are insufficiently plastic in their niche requirements to colonize temperate areas, tropical niches being smaller and less subject to change.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
