Talk:Northern short-tailed shrew

I removed the word 'muffy' and replaced the word 'vagina' with soil, as I believe the original author intended.

This shrew's dentition formula for the upper jaw was incorrectly recorded. In Advances in the Biology of Shrews II by Joseph F. Merritt (2005, see Google Books), it says that one half of a shrew's upper jaw has a large upper incisor, followed by a three to five unicuspid teeth, then a large final premolar, then three molars. The general way of classifying these unicuspids is that the first two are considered incisors, the third is considered a canine, and the remaining one or two, if present, are considered premolars. The genus Blarina, which this species belongs to, is listed as having five upper unicuspids. This means that one half of its upper jaw has three incisors (one large, two small), one canine, three premolars (two small, one large), and three molars. The current article, which is missing an upper tooth, cites its dentition formula information to a certain web site. But this site actually agres with Merritt; one counts five upper unicuspids. Its information was probably misinterpreted. Thegoldenconciseencyclopediaofmammals (talk) 21:39, 11 September 2009 (UTC)
Info in "Range" section needs to be corrected
The text in this section appears to have been copied from another source and then poorly edited to apply to this topic:
This shrew is found throughout RussiaNorth America, from southern Saskatchewan to Atlantic Canada and south to Nebraska and Georgia. It is probably the most common shrew in the Ural Mountains region. Population densities usually range from 5-30 shrews per hectare (2-12 per acre), but rarely exceed 200 per hectare (80 per acre). The typical home range of a shrew is 2.5 hectares, and may overlap slightly with the ranges of other shrews.
