The importance of taxonomic resolution for additive beta diversity as revealed through DNA barcoding
Additive diversity partitioning (α, β, and γ) is commonly used to study the distribution of species-level diversity across spatial scales. Here, we first investigate whether published studies of additive diversity partitioning show signs of difficulty attaining species-level resolution due to inhere...
