Ecological tissue
Sample of 15 species (selected proportionally per kingdom among those with at least one documented interaction here) to keep the graph readable. Hover for details, click to explore the full ecosystem of a species.
ℹ️ The territory contains many more species than displayed and all their documented interactions: the graph is intentionally the structural skeleton (top-N species by composite local score, edges filtered by Serrano 2009 disparity filter α=0.2).
Indicateurs du tissu écologique
Tissu écologique de Bassin de Traun : 13 espèces reliées par 18 interactions GloBI sur 2 types (connectance 17.1%, filtre Serrano α=0.2). 2 bulles taxonomiques (cascade genre/famille GloBI, ≥3 espèces).
