Snapshot: Rodent round-up

[摘要] Crocidura russula, white-toothed shrew, was discovered in Ireland and it is the large rodent-well, larger than its native Irish cousins such as the pygmy shrew-probably arrived on the island as a stowaway on a ship from North Africa or continental Europe, where it is usually found. A dwarf cloud rat was reported this week in the Philippines and they are one of the most spectacular cases of adaptive radiation by mammals anywhere in the world.
