Webb4 juni 2024 · In M. thoracata the dominant parasite was G. genarchella, and this host species was also infected by Gorytocephalus spectabilis which did not infect C. callichthys. The parasite communities were dominated by endoparasites, and species richness of parasites, Shannon diversity index and evenness were similar for both hosts. WebbIn ecology, the Simpson's Diversity Index is used to measure the level of biodiversity in a given area. Specifically, it is concerned with the diversity of species present. In order to determine this, the Simpson’s Diversity Index looks at two factors - richness and evenness.
