Reproducibility of bio volumetric parameters in community reconstruction



Reproducibility of bio volumetric parameters in community reconstruction



Ohio Journal of Science 84(3): 98-102



Criticisms have been raised about the inadequacies of methods in community paleoecological analysis. Until recently, most paleoecological studies were done by specialists in individual taxonomic groups. Because of this specialization, most data collected favored certain groups. Other fossils were either ignored, discounted or lossely labeled qualitatively under descriptive terms as: rare, occasional or abundantly present. Ausich (1981) and Boucot (1981) have independently proposed methods of community analysis whereby the biovolume (shelly biomass) of all taxa present are quantified. To date, little has been done to substantiate the reproducibility of data obtained in this manner for level, soft-bottom, Paleozoic communities. A level, soft-bottom, Middle Devonian animals community is analyzed using the sampling model proposed by Ausich (1981). Trends in the comparisons of biovolume to minimum number counts are reproducible as are trends in each of these catagories within individual horizontally continuous beds. Informational loss and quantitative reproducibility for this new method is an improvement over prior methodology.
