WebbEvenness in an Ecosystem Species evenness refers to the relative population size of each species present in an ecosystem. Measuring evenness is important because an ecosystem that is overwhelmingly dominated by a single or a small number of species has far less diversity than one that is more evenly partitioned between many different species. WebbIn this study, the murine gut microbiome was used as a model system, and changes in microbiome diversity, richness, and evenness over the progression of the cancer and treatment were analyzed. Mice were categorized into four diet cohorts, combinations of either high or low sucrose and high or low omega-3 fatty acids, and two treatment …
