Sizes and Shapes of Liane Leaves

Givnish, Thomas J., Vermeij, Geerat J.·1976·The American Naturalist

Abstract

We have developed evolutionary models to account for ecological patterns in the size and shape of vine leaves. Leaf size is predicted via an economical model in which photosynthetic gains due to enhanced gas exchange are balanced with the metabolic losses incurred in replacing the concomitant water loss. Mechanical efficiency and appropriate orientation in a light field form the basis of our model for leaf shape. Data from montane rain forest in Venezuela and from varied habitats in Costa Rica illustrate the predicted trends along vertical and horizontal microclimatic gradients. Large, cordate-based leaves with long petioles are favored in sunny situations, while small, narrow-based leaves with short petioles are favored in more shady environments. Compound or deeply lobed leaves of the smallest effective size are expected in the most exposed positions.

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.
