Figure 2 in Systematic taxonomy of the Trilobatus sacculifer plexus and descendant Globigerinoidesella fistulosa (planktonic foraminifera)

Figure 2. Hypothetical visualization of morphology in a single dimension. Trait morphology is normally distributed, whereby the mean morphology (solid vertical arrow) should form the type specimen. Morphospecies with high intraspecific variation may be represented by the dot-dashed distribution curve. Conversely, morphospecies with moderate and low intraspecific variation are represented by the dashed and dotted distribution curves, respectively. Finer taxonomic splitting results in more morphospecies with a narrow (dotted line) distribution curve. SD: standard deviation.

Figure 20 in Systematic taxonomy of the Trilobatus sacculifer plexus and descendant Globigerinoidesella fistulosa (planktonic foraminifera)

Figure 20. Example of circularity and curvature values for Globigerinoidesella fistulosa specimens. More lobate values are those in blue, those less lobate are red. Specimens 1 and 2 are more elongate and possess the lowest circularity values, but have a low perimeter length compared to test area and thus also generate low curvature values. Conversely, specimens 3 and 4 have high curvature values due to the protuberances increasing the perimeter length, but also relatively high circularity values because of the large area compared to test diameter (see Material and methods). Scale bar = 200 Lm.

Figure 22. Exponential relationship between maximum test size and test surface area in morphospecies of the Trilobatus sacculifer plexus, and to a lesser extent in Globigerinoidesella fistulosa. The T. sacculifer plexus morphospecies all show comparable relationships, whereas data for G. fistulosa show more scatter.

Figure 21 in Systematic taxonomy of the Trilobatus sacculifer plexus and descendant Globigerinoidesella fistulosa (planktonic foraminifera)

Figure 21. Lobateness of Trilobatus sacculifer plexus morphospecies and Globigerinoidesella fistulosa determined through a combination of circularity and curvature values; A, demonstrates the large variability, but consistently high lobateness values for Globigerinoidesella fistulosa compared to T. sacculifer plexus morphospecies (which have comparatively high circularity and low curvature). Although the T. sacculifer plexus morphospecies appear to form a tight cluster, the lower plot, B, demonstrates the variability in lobateness values (see text for discussion).
