Figure 2. A in Biodiversity of marine tardigrades from the northern coast of Portugal (Iberian Peninsula)

Figure 2. A, observed species accumulation curve (Sobs) and Chao2 species richness estimate for all samples. B, number of species, species restricted to a single habitat (unique) and singletons for each of the three studied habitats. C, nMDS ordinations for each of the sampled localities (note that two shallow subtidal localities are overlapped due to their high similarity).
