The article discusses a new way to measure how evenly different species are distributed in a community. By comparing the actual distribution of species to an ideal even distribution, researchers can calculate a measure of evenness. This measure is based on the diversity of species present and can be visualized as a continuous profile. The researchers also found that the diversity of species in different communities can be linked to how similar or different they are from each other. This new approach helps to better understand the relationships between diversity, evenness, and similarity in ecological communities.
