Tissu écologique
Échantillon de 38 espèces (sélectionnées proportionnellement par règne parmi celles ayant au moins une interaction documentée ici) pour garder le graphe lisible. Survolez pour les détails, cliquez pour explorer l'écosystème complet d'une espèce.
ℹ️ Le territoire contient bien plus d'espèces que celles affichées et toutes leurs interactions documentées : le graphe est volontairement le squelette structurel du tissu (espèces top-N par score composite local, arêtes filtrées par disparity filter Serrano 2009 α=0.2).
