Elevational ranges of pioneer marsh species on the back-barrier island Spiekeroog, Germany

Steinigeweg, Charlotte S.; Siebeneicher, Ole ; Schröder, Boris ; Löbel, Swantje

The dataset includes the collected field data concerning the elevation-mediated pioneer plant species composition in salt marshes. The data were addressed and analysed in the paper “Biotic interactions and site characteristics mediate species-specific elevational niches in salt marsh foremost zones”. The species data (occurence: presence/absence; composition: cover in %) were collected in 2022 in the NW salt marshes on the back-barrier island Spiekeroog, Germany to test if species have different elevational niches, which are shaped by local abiotic conditions and interspecific interactions. Salt marsh species occurrences and covers were measured along 65 seaward-landward transects at two study sites differing in successional age. Elevations were extracted from a digital terrain model.. This data publication contains the original data set containing all relevant data that are needed to reproduce the results and figures of the named publication.

Data Origin:: Experiment and Measurements In October 2022, species composition at both study sites was recorded in 1 m^2 plots along neighbouring seaward-landward transects with a distance of one meter between centroids. Transect points were mapped with a Leica GG04 dGPS and later on matched with site elevations extracted from a digital terrain model (DTM). A photo was taken at every point from 1.50 m height with a cell phone’s camera, from which species cover (%) and occurrence (presence-absence) was estimated for each species by visual inspection.
Used Software:: Editing R (4.2.1, R Core Team 2022)
Description of Data Processing:: We used hierarchical Bayesian models with a zero-augmented beta distribution to analyze the relationships between elevation and cover of individual salt marsh species and total plant cover. Models were fitted using Stan (version 2.26.1 Stan Development Team 2021), run through R (version 4.2.1, R Core Team 2022) using the package brms (version 2.19.0, Bürkner 2017). This package provides an interface that allows coding Stan models in conventional R-syntax.
