Table 2.
Morphometric data on Keronopsis schminkei. Data based on mounted, protargol-impregnated (Foissner 1991, protocol A; Stieve’s fixative strengthened by some ml 2% osmic acid because specimens are fragile), and randomly selected specimens from a non-flooded Petri dish culture. Measurements in μm. CV – coefficient of variation in %, M – median, Max – maximum, Min – minimum, n – number of individuals investigated, SD – standard deviation, SE – standard error of arithmetic mean, – arithmetic mean.
