Asking the Wrong Question in Explaining Tropical Diversity

Enhancement of plant diversity via the Janzen-Connell mechanism is often measured relative to neutral models that ignore species’ competitive differences. Recent modelling indicates this mechanism is ineffective when included in models incorporating species’ demographic variations. This suggests we...

Zusammenfassung:Enhancement of plant diversity via the Janzen-Connell mechanism is often measured relative to neutral models that ignore species’ competitive differences. Recent modelling indicates this mechanism is ineffective when included in models incorporating species’ demographic variations. This suggests we have been asking the wrong questions when measuring the effectiveness of diversity-enhancing mechanisms.
