Columns: bird species names. Rows: study sites Cells: qualitative information (presence/absence) (0/1) #data-plants.xlsx Description: Qualitative list (presence/absence) of plant species and their corresponding study site. Columns: plant species names. Cells: qualitative information (presence/absence) (0/1) #data-cz-values-interactions-parana.xlsx Description: c-z connectivity values for species in the Paraná metanetwork, based on the framework. Columns: interactions: birs-plant interaction names. c: among-module connectivity z: within-module connectivity status: bird status, R = resident, M = migratory sform: life form of plants, AH = Annual herb, CP = Climbing plant, PB = Parasite bush, S = Shrub, S/H = Shrub/Tree, T = Tree, NN = Unidentified species. #data-METANETWORKS-QC.xlsx Description: Qualitative interaction matrix of bird-plant interactions from six sampling sites within the Chaco and Paraná Domains. Rows: sampling sites (6) Columns: interacting species pairs Cells: qualitative information (presence/absence) (0/1) #data-METANETWORKS-QS.xlsx Description: Quantitative interaction matrix of plant–bird interactions from six sampling sites within the Paranaense domain. Rows: sampling sites (6) Columns: interacting species pairs 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.
