Fig. 10 in Two new species of mud dragons (Scalidophora: Kinorhyncha) inhabiting a human-impacted mangrove from Mayotte (Southwestern Indian Ocean)

Fig. 10. Kinorhynch richness (A) as number of species, density (B) as number of individuals per 10 cm 2 and community composition at the two studied sites ("impacted" vs. "control") (C). Boxplots represent the mean value (thick horizontal line within the box), the distributions of 50% of the data (the box), and the highest and lowest values within 95% of the distribution (the whisker). Contribution of each kinorhynch species to the total community is expressed in percentage in relation to the total abundance.
