Across the edge: Spatial segregation drives community structure in tri-trophic multilayer networks at a forest-grassland edge

This dataset accompanies a study investigating species interactions across
forest–grassland edges in southern Brazil, focusing on a tri-trophic
antagonistic system (prey–consumer–parasitoid) within fire-prone mosaics
of Atlantic Forest and Pampa Grassland. The data support analyses of
multitrophic network structure and connectivity across habitat boundaries.
The dataset includes: (i) a node table containing species-level
information (taxonomy and trophic level); (ii) two extended edge lists,
representing intralayer (within-layer links) and interlayer
(across-layer links) interactions in a multilayer network format; and
(iii) bipartite interaction matrices for each habitat layer, enabling
layer-specific analyses. All files are provided in CSV format for
straightforward reuse. These data allow for replicating the published
multilayer and bipartite network analyses, but they can also be repurposed
for alternative approaches, such as network centrality, modularity, or
species turnover studies. Additionally, the bipartite representations can
be integrated into broader meta-analyses of ecological networks. No legal
or ethical restrictions apply, as all species records stem from ecological
field sampling of invertebrates without involving protected or endangered
species. These data provide a valuable resource for advancing
network-based approaches to edge ecology, trophic dynamics, and habitat
connectivity in fire-prone ecosystems.
