Iberian Shrew
French: Musaraigne ibérique / German: |berische Waldspitzmaus / Spanish: Musarana ibérica
Other common names: Lagranja Shrew
Taxonomy. Sorex araneus granarius G. S. Miller, 1910 View in CoL ,
“ La Granja , Segovia, Spain.”
Evidence from mtDNA and nDNA sequences classifies S. granarius in the araneus group. Monotypic.
Distribution. Endemic to the Iberian Peninsula, where it is found in N Portugal (N of Tagus River) and NW & C Spain (Galicia, W Leon, and NW Zamora provinces, and Central System range). View Figure
Descriptive notes. Head—body 63-72 mm (immatures), tail 38-44 mm, ear 5-3-7-4 mm, hindfoot 11-12-5 mm; weight 4-5-8 g (immatures). The Iberian Shrew is medium-sized. Tail is bicolored (sepia above and dark ocher below), slightly exceeding 50% of head-body length. Pelage is generally tricolored. Back is sepia to dark brown, lighter on flanks, and belly is yellowish gray. Juveniles are paler and lack noticeable contrast between dorsum and flanks. Chromosomal complement has 2n = 36/37 and FN = 38-40. X-chromosomeis large metacentric, Y-chromosome is small acrocentric, Y,chromosome 1s medium-sized acrocentric, and the 34-36 autosomes are acrocentric. The Iberian Shrew is the only species in the araneus group with all acrocentric autosomes.
Habitat. Banks of rivers and creeks in mountains of central Spain from sea level up to elevations of ¢.2000 m. The Iberian Shrew is also found in grassy flatlands on the Atlantic shore. Because such habitats are uncommon in the region, the Iberian Shrew has a sporadic distribution.
Food and Feeding. No information.
Breeding. Two pregnant Iberian Shrew females had four and six embryos (April and June) respectively. In Portugal breeding occurs in spring and summer, gestation lasts 18-21 days, and there are 5-7 embryos/pregnant female. Individuals mature at their second year and rarely survive after their second autumn.
Activity patterns. No information.
Movements, Home range and Social organization. No information.
Status and Conservation. Classified as Least Concern on The IUCN Red Last.
