The Seasonal Contribution of C"3 and C"4 Plant Species to Primary Production in a Mixed Prairie

Ode, David J., Tieszen, Larry L., Lerman, Juan Carlos·1980·Ecology

Abstract

A Mixed Prairie in the Northern Great Plains (South Dakota, USA) was studied to determine the floristic composition, according to C 3 and C 4 types, of the seasonal contribution to aboveground production. Twenty—seven of the 305 species present in the Ordway Prairia possessed Kranz anatomy and are assumed to be C 4. Thirty—six percent (19) of the grasses were C 4 whereas <2% (4) of dicots were C 4. Dicots were often weedy and fugitive or introduced species. C 3 plants possessed a mean °13 C value of —26.7%, C 4 plants a value of —12.9%. The biomass of lowland and upland communities possessed low °13 C values in spring. These values increased significantly in the upland community in midsummer to —20.0% indicating a shift to C 4 activity. In fall the biomass °13 C values were again low in both communities indicating a return to C 3 activity. These data show a clear seasonal displacement in production activity of C 3 and C 4 grasses in the Mixed Prairie. A general discussion of the evolution and significance of photosynthetic pathways is included.

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.
