O Primary productivity is higher in the tropics, which increases population sizes and carrying capacities.
O Larger and more thermally stable areas should decrease extinction rates by increasing the size of populations and geographic ranges.
O None of the answers provided.
O The tropics are more climatically stable over time, which provides more time for evolutionary lineages to diversify.
O Primary productivity is lower in the poles, which leads to increased competition and therefore decreases extinction rates.
