Summary[edit]

Description
Français : Comparaison entre le nombre de fourrures rapportées par les trappeurs au comptoir de la Baie d'Hudson (série d'environ 90 ans) pour le lynx canadien et le lièvre américain. Ce graphique montre que les deux espèces ont une dynamique cyclique de population. Il montre aussi qu'elles semblent en interactions durables, tout en reflétant aussi des changements locaux, dont météorologiques liés à l'ENSO (El Niño Southern Oscillation)[1]. Source : d'après des archives statistiques collectées par Odum, publiées en 1953. ; Odum EP (1953) Fundamentals of ecology. WB Saunders, Philadephia
