Hello,

The reasons for high diversity in Tropical regions are :

• These regions receive more sunlight than any other regions, this helps in more productivity.
• These regions have less distortions or variations in seasons and have a nearly constant environment.

Best Wishes.

Hello ,

Reasons for high diversity in tropical regions :

• Frequent Glaciation is common in Temperate Regions , this type of disturbance was absent in tropical regions and therefore species continued to flourish and evolve undisturbed for millions of years and thus had a long evolutionary time for species diversification.
• Absence of unfavourable seasons in tropical regions , these regions are less seasonal, more constant and predictable.It helps to gain more niche specialisation and species diversity.
• Environmental Stability
• Species Area relationship : Species richness increased with the increase in explored area .
