Introducing untb, an R Package For Simulating Ecological Drift Under the Unified Neutral Theory of Biodiversity [PDF]

open access: yes
The distribution of abundance amongst species with similar ways of life is a classical problem in ecology. The unified neutral theory of biodiversity, due to Hubbell, states that observed population dynamics may be explained on the assumption of per ...
