Plant–floral visitor interaction networks and environmental variables from potato field margins in southeastern Buenos Aires, Argentina

This repository contains the data and derived analytical outputs supporting a study of plant–floral visitor interaction networks in potato field margins in southeastern Buenos Aires, Argentina. Data were collected from 35 independent sampling sites between 2020 and 2023 through standardized transect surveys. A total of 4,371 interactions were recorded between 52 flowering plant taxa and 123 floral visitor morphospecies.

The deposited files include quantitative plant–floral visitor interaction records, local field-margin variables, landscape metrics calculated for three non-overlapping spatial bands (0–500 m, 500–1000 m, and 1000–2000 m), observed network metrics, and standardized effect sizes (SES) for network-level specialization (H2′), weighted nestedness (WNODF), and modularity. The repository also contains network metrics and SES recalculated after excluding Apis mellifera, comparisons between complete networks and networks without this species, model-selection outputs, coefficient tables, residual diagnostics, spatial-autocorrelation tests, a variable dictionary, metadata, and quality-control summaries.

Local environmental variables include field-margin width, flowering plant richness, floral unit abundance, grass cover, and bare-soil cover. Landscape variables include the proportion of semi-natural habitat, Shannon landscape diversity, and edge density. The landscape variables were calculated separately for the three spatial bands.

The files are temporarily under restricted access while the associated manuscript is being prepared or evaluated. They are intended to be made openly available following acceptance or publication of the associated article. The analytical R code is not included in the current version of the repository.
