Taxonomy and evolution
Sorex samniticus was described in 1926 by Altobello. It was previously considered a subspecies of S. araneus, but separated from it in 1979.[2][3] S. samniticus has a subspecies, S. samniticus garganicus, which is smaller than the standard nominate subspecies S. s. samniticus.[4]
A genetic analysis estimated that the Apenine shrew diverged from other shrews in the genus Sorex approximately 2.7 million years, further in time than the other species of the araneus group.[5][4]
Description
The Apennine shrew is very similar in appearance to the common shrew (Sorex araneus), but it can be distinguished by the upper incisors.[4]
It has 52 pairs of chromosomes, unlike other morphologically similar shrews such as the common shrew.[6]
Habitat, range, and conservation status
The Apennine shrew is endemic to Italy. It has been found from 300 metres (980 ft) to 1,160 metres (3,810 ft) above sea level. It prefers shrubland.[1] A 2007 study found that its population decreased as the amount of Quercus cerris (a species of oak) and Castanea sativa (sweet chestnu) trees increased.[7]
It is listed as a species of least concern by the IUCN due to its wide range and lack of known threats.[1]
