Explanation:

Species richness is generally lower in the Arctic than at lower latitudes, and richness also tends to decline from the low to high Arctic. Many hypotheses have been advanced to explain the overall decline of biodiversity with increasing latitude, although there is still no consensus about a mechanistic explanation. Abiotic factors include lower available energy and area at high latitudes, and the relatively young age of Arctic ecosystems. Among biotic factors, latitudinal differences in rates of diversification have been suggested, but empirical evidence for this as a general principle is lacking.
