An improved nonparametric lower bound of species richness via a modified good-turing frequency formula.
Chiu CH, Wang YT, Walther BA, Chao A. Chiu CH, et al. Among authors: chao a. Biometrics. 2014 Sep;70(3):671-82. doi: 10.1111/biom.12200. Epub 2014 Jun 19. Biometrics. 2014. PMID: 24945937
Applying a modified Good-Turing frequency formula, we derive an approximate formula for the first-order bias of this traditional lower bound. ...The proposed lower bound is nonparametric in the sense that it is universally valid for any species abundance distribution. A

Hill-Chao numbers allow decomposing gamma multifunctionality into alpha and beta components.
Chao A, Chiu CH, Hu KH, van der Plas F, Cadotte MW, Mitesser O, Thorn S, Mori AS, Scherer-Lorenzen M, Eisenhauer N, Bässler C, Delory BM, Feldhaar H, Fichtner A, Hothorn T, Peters MK, Pierick K, von Oheimb G, Müller J. Chao A, et al. Ecol Lett. 2024 Jan;27(1):e14336. doi: 10.1111/ele.14336. Epub 2023 Dec 10. Ecol Lett. 2024. PMID: 38073071
This research has provided knowledge gained mainly at the local alpha scale (i.e. within ecosystems), but the increasing homogenization of landscapes in the Anthropocene has raised the potential that declining biodiversity at the beta (across ecosystems) and gamma scales is likel …
