Data and Code from: Evolutionary Origins Override Contemporary Environmental Filtering in Shaping Terrestrial Algae Diversity
Year: 2025
Type: article
Abstract: This study incorporates 96 unpublished metabarcoding datasets of terrestrial, phyllosphere algae collected from 16 sites located across China. Each dataset consists of a site-tree leaf sample. Each sample comprised three or more leaves (or tissues of varying leaf sizes) gathered from trees at heights ranging from 0.5 to 2.0 m aboveground. The full-length 18S rDNA gene was amplified in a 50 mL reaction mixture using eukaryotic universal primers, Euk18SA and Euk18SB.We developed a modeling framework that separates the effects of the interplay between contemporary filtering and evolutionary history in shaping empirical biodiversity. The species-distribution model has two modules that describe the observational and underlying processes that reflect contemporary filtering and phylogenetic history. With Bayesian estimation of model parameters, we fitted our species-distribution model using the frequency of species occurrence. This model fitting was done with the Bayesian framework “Stan” and its R interface “cmdstanr”.
