Web12 mei 2024 · 1. Introduction. The latitudinal diversity gradient (LDG) refers to the increase of species richness from the poles to the Equator. Terrestrial organisms usually have peak diversities near the Equator [1–3], whereas bimodal diversity patterns with a dip at the Equator are more common in the oceans [4–11].Numerous hypotheses have been put … WebFinally, the finding that the steepest latitudinal gradients occur in the geologically youngest clades of bivalves (50, 53) is also consistent with a dynamic involving preferential … Webhypothesis that this pattern is related to the productivity gradient in the food-starved deep North Atlantic.
