The article discusses the concept of biodiversity and raises important questions about how to measure and estimate it. It explores whether biodiversity is just about the number of species in an area, how to measure it beyond species count, and if all species are equally important. The researchers also consider including genetic variance within species, the contribution of different species to overall biodiversity, and indicators of high biodiversity areas. They also discuss estimating biodiversity in different taxonomic groups. The modern idea of biological diversity is credited to Elliot R. Norse and his colleagues.
