Abstract: = 0.479) was almost entirely attributable to between-area covariance and approached zero after area adjustment, whereas selected nicotine-carbohydrate and phytol-glycosidic relationships contained larger area × position contributions. The framework therefore provides source-aware interpretation of pooled multimodal correlations; its principal limitations are dependence on structured sampling, tentative compound annotation from archived total-ion-current data and limited transfer to unseen geographic origins.
