Ecologist has proposed following explanation to lead biodiversity at tropic.

a) Higher productivity in the tropics allows for more species

b)  Environments are more stable and predictable in the tropics, with fairly constant temperatures and rainfall levels year-round

c) Predators and pathogens limit competition in the tropics, which allows more species to coexist

d) High evolutionary speed at tropic than temperate
