  • Star-Nosed Mole, Condylura Cristata
    The Journal the Elisha Mitchell Scien USE OF AN UPLAND PINE FOREST BY THE STAR-NOSED MOLE, CONDYLURA CRISTATA TIMOTHY S. MCCAY’ Museum of Natural History, Institute of Ecology University of Georgia, Athens, GA 30602 MARK J. KOMOROSKI Savannah River Ecology Laboratory Drawer E, Aiken, SC 29802 WILLIAM M. FORD USDA Forest Service, Femow Experimental Forest Box 404, Parsons, WV 26287 Key Words: Star-nosed mole; Condylura cristata; pine forests; dispersal. The star-nosed mole (Condylura cristata) is a semi-aquatic insectivore, corn- manly found near marshy areas and streams (Hamilton, 1931; Petersen and Yates, 1980; Webster et al., 1985). We report two captures of star-nosed moles from a xeric, upland pine forest more than 500 m from the nearest persistent source of water. Both captures occurred during rainy nights, suggesting that star-nosed moles use rain events as opportunities for dispersal through upland habitats. We captured star-nosed moles on 22 April and 17 July 1998 in a loblolly-pine (Pinus taeda) plantation at the Savannah River Site National Environmental Re- search Park (SRS; 33”20’N, 81”31’W) in the Upper Coastal Plain Province of South Carolina. The forest in which the moles were captured was approximately 45 yr old, with sparse mid- and under-story vegetative cover. Both natural and planted pine forests dominated the upland habitats at the SRS (Workman and McLeod, 1990). Soils were sandy and well-drained; leaf-litter consisted exclu- sively of pine leaves. Moles were captured with arrays of drift-fences and pitfall traps that were monitored daily over the periods 3 April to 9 May and 3 to 17.

The diversity of parks and their resources are reflected in their designations as national parks, seashores, historic sites, recreation areas, military parks, memorials, and rivers and trails. Biological, physical, and social science research results, natural resource inventory and monitoring data, scientific literature reviews, bibliographies, and proceedings of technical workshops and conferences related to these park units are disseminated through the NPS/NER Technical Report (NRTR) and Natural Resources Report (NRR) series. The reports are a continuation of series with previous acronyms of NPS/PHSO, NPS/MAR, NPS/BSO-RNR, and NPS/NERBOST. Individual parks may also disseminate information through their own report series. Natural Resources Reports are the designated medium for information on technologies and resource management methods; "how to" resource management papers; proceedings of resource management workshops or conferences; and natural resource program descriptions and resource action plans.

  • Crawford's Desert Shrew
    Notiosorex crawfordi (Coues, 1877) DESH Joshua Laerm and W. Mark Ford CONTENT AND TAXONOMIC COMMENTS Notiosorex is a monotypic genus. The Crawford’s desert shrew (Notiosorex crawfordi)hastwosubspecies; one (N. c. crawfordi) occurs in the South. The litera- ture on Crawford’s desert shrew was reviewed by Armstrong and Jones (1972). DISTINGUISHING CHARACTERISTICS Crawford’s desert shrew is a small, short-tailed soricid with small but conspicuous ears. Similar to most shrews, the tiny eyes are concealed although Crawford’s desert shrews can see well (Sealander and Heidt 1990). Measurements are: total length, 77–98 mm; tail, 22–30 mm; hind foot, 9–13 mm; weight, 3–6 g. The snout is long and pointed. The pelage is silver-gray to brownish gray dorsally and pale gray to silver-gray ventrally, with a well-haired and indistinctly bicolored tail. In addition to its mouse-like appearance, the Crawford’s desert shrew can be distinguished by dental comparison from three sympatric short-tailed shrews, Elliot’s short-tailed shrew (Blarina hylophaga), the least shrew (Cryptotis parva) and the southeastern shrew (Sorex longirostris). The Crawford’s desert shrew has 3 pairs of unicuspids whereas there are 4 in the least shrew and 5 in Elliot’s short-tailed shrew and the southeast- ern shrew. The dental formula is: I 3/1, C 1/1, P 1/1, M 3/3 = 28 (Figure 1). See keys for additional details. CONSERVATION STATUS The Crawford’s desert shrew has a global rank of Secure (NatureServe 2007). It is considered Appar- ently Secure in Texas, Vulnerable in Oklahoma, and Critically Imperiled in Arkansas.

  • Proceedings of the Indiana Academy of Science
    Dental Anomalies in Three Species of Shrews from Indiana Thomas W. French* Department of Life Sciences Indiana State University Terre Haute, Indiana 47809 Introduction Dental anomalies in shrews are not common. Hall (1940) found no cases of miss- ing or extra teeth in 1,837 specimens of North American shrews and Jackson (1928) reported only 5 specimens (0.05%) with dental anomalies out of 10,431 Sorex and Microsorex examined. Information on dental anomalies in shrews has been best sum- marized by Choate (1968). Most reported dental anomalies result from a reduction in the number of upper, and to a lesser extent, lower unicuspid teeth (12, 13, C, P2, P3, 13, and c of Choate 1968). No case of genetically deleted molariforms or first incisors has been reported in shrews. Subnumerary dentitions have been reported from Sorex araneus (Reinwaldt 1961), S. cinereus ohionensis (Bole and Moulthrop 1942), 5. minutus (Reinwaldt 1961), S. obscurus longicauda (Jackson 1928), S. tundrensis (Pruitt 1957), Blarina brevicauda and B. b. carolinensis (= B. carolinensis) (Choate 1968), B. adamsi (from the upper Pliocene— Hibbard 1953), Cryptotis goodwini, C. mexicana, C. nigrescens, and C. parva (Choate 1970), and Microsorex hoyi (Jackson 1928). Supernumerary dental formulas have resulted most often from extra upper unicuspids and have been reported from 1 Sorex o. obscurus (Jackson 1928), 1 S. s. saussurei (Hooper 1946), 3 Blarina carolinensis (Choate 1968), 1 Crocidura cyanea, 2 C. hirta (Meester 1953), and 3 C. marquensis (Dippenaar 1978). Extra unicuspids in the lower jaw have been reported only from Blarina brevicauda (Hibbard 1953). Supernumerary molariform teeth in shrews are especially scarce.
