Biodiversity is more in tropical latitudes than in temperate ones. The reasons are:

Speciation is a function of time. The temperate regions were subjected to frequent glaciation in the past, while the tropics have remained undisturbed and so had longer time to evolve more species diversity.
More solar radiation is available in tropical region. This leads directly to more productivity and indirectly to greater species diversity.
The environment of tropics is less seasonal and relatively more constant and predictable, which encourages niche specialisation and species diversity.
