Dans ce script, nous décrivons les décisions prises pour ajuster des modèles d'équations structurelles afin de suivre le flux des nutriments dans les réseaux trophiques des îles. Nous trouvons la multicolinéarité dans notre approche initiale (à l'aide du fichier « ibt-sem-data-2021.csv ») et finissons par prendre des valeurs moyennes de δ15N et δ13C de tous les échantillons de plantes sur chaque île pour une seule valeur δ15N et δ13C de plante à l'échelle de l'île pour l'analyse (dans « ibt-sem-data-2021-plants-combined.csv »).\n\nObrist DS, Ernst CE, Fitzpatrick OT,
