Overview

Brief Summary

Species Abstract

Surdisorex polulus is a Vulnerable species of Mole Shrews that occurs only in the East African montane moorlands, an ecoregion with acidic soils occurring above 3000 metres in elevation in equatorial Africa. The climate is harsh, with frost occurring nightly and hot, high solar intensity daytime temperatures.

There are a number of endemic species to the montane moorlands that are associates of S. polulus.

There are a number of endemic small mammals to the East African montane moorlands. One endemic mammal to the ecoregion is the Mount Kenya Mole Shrew (Surdisorex polulus), which is found only at the higher elevations of Mount Kenya; moreover, this rodent is classified as a Vulnerable species. Another endemic mammal is the Aberdare Mole Shrew (Surdisorex norae), which is known only to the higher elevations of the Aberdare Mountain Range in Kenya. The King Mole Rat (Tachyoryctes rex) is another endemic rodent that is known only to the higher elevations of Mount Kenya within the ecoregion. The Vulnerable East African Highland Shrew (Crocidura allex) is a near endemic to the ecoregion, that is also found in upper elevation portions of the adjacent East African montane forests ecoregion. Another imputed endemic mammal is Peter's Musk Shrew (Crocidura gracilipes) - See more at: http://www.eoearth.org/article/East_African_montane_moorlands?topic=49597#sthash.shCQvtJr.dpuf

The Mt. Kenya Mole Shrew (Surdisorex polulus) is a species of mammal in the Soricidae family. It is endemic to Mount Kenya in Kenya. Its natural habitat is tropical high-altitude bamboo and grassland.

Taxonomy[edit source | edit]

The taxonomy of the Mt. Kenya Mole Shrew is as follows:

  • Kingdom-Animalia
  • Phylum-Chordata
  • Class-Mammalia
  • Order-Eulipotyphla
  • Family-Soricidae[1]

Biology[edit source | edit]

The Mt. Kenya Mole Shrew is listed as vulnerable to become endangered because it is known to only be found in a single location that is the highlands of Mount Kenya. The habitat loss that is resulting from climate change represents a reasonable future threat. This species is found in a terrestrial environment, and the species inhabits dense montane grassland.
