Ondatra zibethicus

description: Ondatra zibethicus (Linnaeus 1766)
[Castor] zibethicus Linnaeus 1766, Syst. Nat., 12th ed., Vol. 1: 79.
Type Locality: E Canada.
Vernacular Names: Common Muskrat.
Synonyms: Ondatra albus (Sabine 1823); Ondatra americana Tiedemann 1808; Ondatra aquilonius (Bangs 1899); Ondatra bernardi Goldman 1932; Ondatra cinnamominus (Hollister 1910); Ondatra hudsonius (Preble 1902); Ondatra goldmani Huey 1938; Ondatra maculosa (Richardson 1829); Ondatra macrodon (Merriam 1897); Ondatra mergens (Hollister 1910); Ondatra niger (Fitzinger 1867); Ondatra niger (Brass 1911); Ondatra nigra (Richardson 1829); Ondatra obscurus (Bangs 1894); Ondatra occipitalis (Elliot 1903); Ondatra osoyoosensis (Lord 1863); Ondatra pallidus (Mearns 1890); Ondatra ripensis (Bailey 1902); Ondatra rivalicius (Bangs 1895); Ondatra spatulatus (Osgood 1900); Ondatra varius (Fitzinger 1867).
Distribution: North America, north to the treeline, including Newfoundland; south to the Gulf of México, Rio Grande and lower Colorado River valleys. Introduced to Czech Republic in 1905 and now widespread in the Palearctic, including C and N Europe, most of Ukraine, Russia, and Siberia, adjacent parts of Mongolia and scattered throughout China, NE Korea, and Honshu Isl, Japan (Gromov and Erbajeva, 1995, for Eurasian range; Mitchell-Jones et al., 1999, for European range); also into southernmost Argentina (Galliari et al., 1996; Olrog and Lucero, 1981).
Conservation: IUCN – Data Deficient as O. z. ripensis, otherwise Lower Risk (lc).
Discussion: Subspecific classification revised, under the name Fiber, by Hollister (1911); Whitaker and Hamilton (1998) regarded macrodon as inseparable from O. z. zibethicus. Comprehensive summaries of systematics, ecology, population biology, and economic status provided by Pietsch (1982), Perry (1982), and Sokolov and Lavrov (1993). Correlation between masticatory muscles and cranial architecture monographed by Vendeloo (1953). Viriot et al. (1993) used digital imaging to analyze molar ontogeny and wear effects in extant samples; the technique may quantitatively refine the evolutionary chronocline as traced in the stratigraphic record (e.g., Chaline et al., 1999; R. A. Martin, 1996).
History of introductions, mostly for fur farming, and early population spread in Eurasia and USA reviewed by Storer (1937) and Willner (1984). Recent faunal studies—including records of introduction, distribution, and population expansion—collectively underscore the muskrat’s pervasive exploitation of Eurasian aquatic habitats: Netherlands (Hoeve and Wijlaars, 1992); Sumava Mtn region, SW Bohemia (Andĕra and Červený, 1994); Switzerland (Hausser, 1995); Italy (Amori et al., 1999; Andreotti et al., 2001); Slovakia (Mošanský, 1994; Stanko and Mošanský, 2000); Czech Republic (Šmaha, 1996); Serbia and Montenegro (Petrov, 1992); Slovenia (Kryštufek, 1991); E Baltic region (Miljutin, 1997, 1998; Timm et al., 1998); Korea (Won and Smith, 1999); Svjatoj Nos peninsula and isthmus in Lake Baikal (Reiter et al., 1995); Kamchatka region (Nikanorov, 2000); Russia and adjacent regions (Gromov and Erbajeva, 1995); China (Zhang et al., 1997); and Japan (Kaneko, 1994).
