The Asian house shrew (Suncus murinus) is a shrew species native to South and Southeast Asia that has been listed as Least Concern on the IUCN Red List since 2008 because of its large population and wide distribution.

The introduced shrew, Suncus murinus, was discovered on Guam in May 1953. Its spread was rapid and probably facilitated by the transport of goods. The shrew was discovered on Saipan in August 1962 and spread from an area of about four square miles around the harbor to cover the rest of the island in about 18 months.

The large musk shrew, Suncus murinus (Linnaeus), was first taken on Guam in May, 1953 by the author. This is the first record, to his knowledge, of the species from an oceanic island.

Jan 1, 2004 · In the 1960s, a group of musk shrews was trapped in Guam and brought to the United States by Dr. Gil Dryden. He established a colony and accomplished much of the initial characterization of their physiological and reproductive characteristics.

length up to 8cm (Baker, 2005). A study comparing shrew populations from Guam and Madagascar showed some significant differences in appearance, body weight and length, with female shrews from Madagascar being heavier than female.

Apr 6, 2006 · A study comparing shrew populations from Guam and Madagascar showed some significant differences in appearance, body weight and length, with female shrews from Madagascar being heavier than females from Guam (Hasler et al. 1977).

Although both species entered Guam via the port, the snake was the first colonist of the port and southern areas of the island, whereas the shrew was the first colonist of the northern end of Guam.

ABSTRACT.-Breeding colonies of musk shrews (Suncus murinus) from the islands of Guam (G) and Madagascar (M) were maintained. Physical, physiological, and behav- ioral differences were observed between M, G, and "hybrid" (H, an offspring of a G/M mating) shrews. The shrews differed in appearance, body weight, and length.

The shrew has had no observable impact on ground-nesting birds. A marked decline in trap success for Mus muscu/us on Guam from 1958 to 1969 is the only measured change in the vertebrate fauna that can be attributed to the shrew, al­ though changes in …
