Cells: quantitative information, interaction frequency values

Scripts Overview

1. script-metanetwork-plot.txt Constructs and plots a meta-network of species interactions across sampling sites. Uses bipartite networks to visualize site-species linkage.

2. script-centrality.txt Calculates and visualizes species-level centrality metrics (degree, betweenness) from the meta-network. Includes plots by domain (Chaco/Paraná).

3. script-cz-values-interactions-paranatable.txt Calculates c and z values (within-module and among-module connectivity) and generates tables distinguishing interaction roles within Paraná sites.

4. script-czvalues-vs-status-lifeform.txt Analyzes the relationship between c–z values and species traits (bird status and plant life forms). Outputs comparative boxplots.

5. script-heatmap-plot.txt Creates heatmaps representing the beta diversity across sites or modules.

6. script-null-models.txt Generates null models to assess whether observed network metrics (e.g., connectance) differ from expectations using "r2dtable" and "vaznull" randomization. Outputs Z-scores and p-values.

7. script-upset-plot.txt Creates upset plots to visualize shared and unique interactions/bird species/plant species across sites. Includes domain-specific color schemes and classification by group.

8. script-beta-harvesine-pearsontest-manteltest.txt Performs beta diversity analysis of interaction composition across sites. Calculates Jaccard or Sørensen dissimilarity, applies the Haversine formula to compute distances, and conducts Mantel tests.
