Biodiversity of North American Mammals
Science Center Objects
The Challenge: Despite more than a century and a half of study, accurate understanding of the diversity North American mammalian species and the distribution of those species remains unrefined. Yet this understanding is essential for determining the conservation status of species, for mapping out potential disease reservoirs, and for understanding the response of species to habitat perturbation and climate change.
The Science: Systematic and taxonomic study of species and subspecies documents morphological, genetic, and geographical aspects of species limits. Study of historical records and type localities provides insight into genetic and distributional shifts that have already occurred.
The Future: Comprehensive study of mammalian species and species limits contributes to a better understanding of what aspects of the environment control species interactions, population abundances, and community diversity.
Three new species of small-eared shrews, genus Cryptotis, from El Salvador and Guatemala (Mammalia: Eulipotyphla: Soricidae)
The Cryptotis goldmani group of small-eared shrews (Eulipotyphla: Soricidae: Cryptotis Pomel, 1848) is a clade of semifossorially adapted species discontinuously distributed in moist highlands from central Mexico to western Panama. Inspection of a recent collection of small mammals resulting from field work in Guatemala provided the impetus for a...
Woodman, Neal Shrews (Eulipotyphla, Soricidae) of Guatemala /Musarañas (Eulipotyphla, Soricidae) de Guatemala
Shrews (Soricidae) are the only members of the mammalian order Eulipotyphla that occur in Central and South America. In Guatemala, 15 species have been recorded belonging to the genera Cryptotis and Sorex, three of which are new and undescribed. Two additional species are expected to be discovered in the country based on their known distributions...
Matson, John O.; Woodman, Neal Identification and distribution of the Olympic Shrew (Eulipotyphla: Soricidae), Sorex rohweri Rausch et al., 2007 in Oregon and Washington, based on USNM specimens
Review of specimens of long-tailed shrews (Mammalia, Soricidae, Sorex) from the northwestern United States in the National Museum of Natural History (USNM), Washington, DC, has revealed the presence of the Olympic Shrew, Sorex rohweri Rausch et al., 2007, in the Coastal Range west of the Willamette Valley in Oregon. This determination nearly...
Woodman, Neal; Fisher, Robert D. Who invented the mule deer (Odocoileus hemionus)? On the authorship of the fraudulent 1812 journal of Charles Le Raye
The captivity journal of Charles Le Raye was first published in 1812 as a chapter in A topographical description of the state of Ohio, Indiana Territory, and Louisiana, a volume authored anonymously by a late officer in the U. S. Army. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had travelled across...
Woodman, Neal Shippingport, Kentucky, is the type locality for the white-footed mouse, Peromyscus leucopus (Rafinesque, 1818) (Mammalia: Rodentia: Cricetidae)
The white-footed mouse, Musculus leucopus Rafinesque, 1818 (= Peromyscus leucopus), is a common small mammal that is widespread in the eastern and central United States. Its abundance in many habitats renders it ecologically important, and its status as a reservoir for hantavirus and Lyme disease gives the species medical and economic significance...
Woodman, Neal A new species of small-eared shrew (Mammalia, Eulipotyphla, Cryptotis) from the Lacandona rain forest, Mexico
The diversity and distribution of mammals in the American tropics remain incompletely known. We describe a new species of small-eared shrew (Soricidae, Cryptotis) from the Lacandona rain forest, Chiapas, southern Mexico. The new species is distinguished from other species of Cryptotis on the basis of a unique combination of pelage coloration, size...
Guevara, Lázaro; Sánchez-Cordero, Víctor; León-Paniagua, Livia; Woodman, Neal Small mammals from the Chelemhá Cloud Forest Reserve, Alta Verapaz, Guatemala
We surveyed the small mammals of remnant mixed hardwood-coniferous cloud forest at elevations ranging from 2,100–2,300 m in the Chelemhá Cloud Forest Reserve, Alta Verapaz, Guatemala. Removal-trapping using a combination of live traps, snap traps, and pitfall traps for 6 days in January 2007 resulted in 175 captures of 15 species of...
Matson, Jason O.; Ordóñez-Garza, Nicté; Woodman, Neal; Bulmer, Walter; Eckerlin, Ralph P.; Hanson, J. Delton The type localities of the mule deer, Odocoileus hemionus (Rafinesque, 1817), and the Kansas white-tailed deer, Odocoileus virginianus macrourus (Rafinesque, 1817), are not where we thought they were
Among the iconic mammals of the North American West is the mule deer (Odocoileus hemionus). This species and a western subspecies of the white-tailed deer (Odocoileus virginianus macrourus) were two of seven mammals originally named and described as new species in 1817 by Constantine S. Rafinesque. Rafinesque never saw the animals that he named....
Woodman, Neal The identity of the enigmatic "Black Shrew" (Sorex niger Ord, 1815)
The scientific name Sorex niger Ord, 1815 (Mammalia, Soricidae) was originally applied to a North American species that George Ord called the “Black Shrew.” The origin of the name “Black Shrew,” however, was obscure, and Samuel Rhoads subsequently wrote that the species represented by this name could not be determined. The names Sorex niger Ord...
Woodman, Neal This shrew is a jumping mouse (Mammalia, Dipodidae): Sorex dichrurus Rafinesque 1833 is a synonym of Zapus hudsonius (Zimmermann 1780)
Constantine S. Rafinesque described Sorex dichrurus as a shrew in 1833, based on a specimen he found in a proprietary museum near Niagara Falls on the New York/Ontario border. The name subsequently has been ignored by the scientific community. By describing this specimen as a shrew and ascribing it to the genus Sorex, Rafinesque clearly indicated...
Carleton, Michael D.; Woodman, Neal Distributional records of shrews (Mammalia, Soricomorpha, Soricidae) from Northern Central America with the first record of Sorex from Honduras
Short term surveys for small mammals in Guatemala and Honduras during 1992–2009 provided important new records for 12 taxa of shrews from 24 localities. These locality records expand the known geographic distributions for five species and for the genus Sorex Linnaeus, 1758: the geographic range of Cryptotis goodwini Jackson,...
Woodman, Neal; Matson, John O.; McCarthy, Timothy J.; Eckerlin, Ralph P.; Bulmer, Walter; Ordonez-Garza, Nicte Taxonomic status and relationships of Sorex obscurus parvidens Jackson, 1921, from California
The San Bernardino shrew, Sorex obscurus parvidens Jackson, 1921, is a population inhabiting the San Bernardino and San Gabriel mountains of southern California. For the past 9 decades, this population has been considered either a subspecies of S. obscurus Merriam, 1895, S. vagrans Baird, 1857, or S. monticola Merriam, 1890; or an undifferentiated...
