FIG. 4 in Earthworms (Oligochaeta, Clitellata) of the Mitaraka range (French Guiana): commented checklist with description of one genus and eighteen species new to science

FIG. 4. — Earthworm species diversity in the Mitaraka range: A, incidence–based rarefaction and extrapolation curve showing species number accumulation as a function of the number of plots sampled within the study area; B, abundance–based rarefaction and extrapolation curves showing species number accumulation as a function of the number of earthworm individuals sampled within four main types of habitats (Inselberg habitats include rocky savannahs, transition and hilltop forests); B, abundance–based rarefaction and extrapolation curves showing species number accumulation as a function of the number of earthworm individuals sampled within four main types of microhabitats (Litter, litter accumulations on granitic rocks; Roots, root mat of terrestrial bromeliads; Soil, organo-mineral soil and sediments; Trunks, decaying trunks and associated termite mounds); D, box–plots of community-scale species richness for the four main type of habitats (as in B). In A-C, solid curves: rarefaction curves; dotted curves:extrapolation curves. In D, diamond symbol: mean; coloured dots: outliers; grey dots: individual values.
