Give three hypotheses for explaining why tropics show greatest levels of species
There are three different hypotheses proposed by scientists for explaining
species richness in the tropics.
latitudes receive more solar energy than temperate regions, which leads to high
productivity and high species diversity.
regions have less seasonal variations and have a more or less constant
environment. This promotes the niche specialization and thus, high species
regions were subjected to glaciations during the ice age, while tropical regions
remained undisturbed which led to an increase in the species diversity in this
