Tree Communities, Microhabitat Characteristics, and Small Mammals Associated with the Endangered Rock Vole, Microtus Chrotorrhinus, in Virginia
2003SOUTHEASTERN NATURALIST 2(4):547–558 TREE COMMUNITIES, MICROHABITAT CHARACTERISTICS, AND SMALL MAMMALS ASSOCIATED WITH THE ENDANGERED ROCK VOLE, MICROTUS CHROTORRHINUS, IN VIRGINIA 1,2,* 1 JOHN L. ORROCK AND JOHN F. PAGELS ABSTRACT - We located the endangered rock vole, Microtus chrotorrhinus, at 3 of 59 sites in mixed mesophytic forests in the southern Appalachians. Rock voles were always found within mixed mesophytic habitats characterized by yellow birch, Betula alleghaniensis, rather than mixed mesophytic habitats dominated by other tree species. We compared the tree communities, microhabi- tat features, and small mammals found within three groups of habitats: sites where M. chrotorrhinus was found, yellow birch habitats where M. chrotorrhinus was not found, and other mixed mesophytic habitats where M. chrotorrhinus was not found. Sites occupied by M. chrotorrhinus had greater amounts of large, rocky substrate, greater incidence of moss, and a more north- west aspect than yellow birch and other mixed mesophytic sites without M. chrotorrhinus. Moreover, sites with rock voles had larger trees and were signifi- cantly older than sites without M. chrotorrhinus. Red-backed voles, Clethrionomys gapperi, are readily sampled by live-trap methods and were significantly more abundant at sites with M. chrotorrhinus, and may thus be a promising indicator species. Our results suggest that mixed mesophytic forests, especially older stands dominated by yellow birch and rocky substrate, should be managed with care to preserve M. chrotorrhinus habitat. INTRODUCTION The rock vole, Microtus chrotorrhinus, is an endangered species in Virginia (Roble 2001). Microtus chrotorrhinus is a boreal rodent whose geographic distribution extends from eastern Canada south along the Appalachians to North Carolina and Tennessee (Kirkland and Jannett 1982). -
Woodland Vole Microtus Pinetorum
woodland vole Microtus pinetorum Kingdom: Animalia FEATURES Phylum: Chordata The woodland vole has red-brown body fur with Class: Mammalia light red-brown fur on the belly. The head-body Order: Rodentia length is about three to four inches. The claws on the front feet are larger than the ones on the back Family: Cricetidae feet. The tail is very short, and the eyes are tiny. ILLINOIS STATUS common, native BEHAVIORS The woodland vole may be found statewide in Illinois. This rodent lives on the forest floor in dry woods with oaks, hickories and maples. It also lives in roadside vegetation, orchards, pastures and weedy fields. The woodland vole eats berries, roots, nuts, seeds, wild onions and a variety of green vegetation. It is active day and night. This vole uses burrows under the soil that it digs or that were dug by other small mammals. It digs with the front feet, using the hind feet to push the loose soil behind it. representative specimen The head is used to push loose dirt out of the burrow. The nest is built in a burrow or under an object on the ground that can be reached by a branch of the burrow. Several woodland voles may use the same nest. Two mating seasons occur in a year with young born from March through April and August through November. A litter contains two or three young. Young are helpless at birth but develop rapidly, living on their own at about three weeks of ILLINOIS RANGE age. Sexual maturity is attained between two and three months of age. -

Moles, Shrews, Mice, and More
Moles, RESEARCHERS FOCUS IN ON Shrews, NEW HAMPSHIRE’S MANY SMALL Mice MAMMALS and more 8 NovemberSeptember / / December October 2016 2016 by ELLEN SNYDER mall mammals – those weighing less than six ounces – are a surprisingly diverse group. In New England, they include mice, voles, bog lemmings, flying squir- Srels, chipmunks, moles and shrews. Researchers study small mammals because they are common, widespread, diverse, easily handled and reproduce often. My father, Dana Snyder, was one of those researchers. In the 1960s, when I was just four years old, he began a long-term study of the ecology of the eastern chipmunk in the Green Mountains of southern Vermont. Our summer camping trips to his study site infused me with a fondness for small mammals, especially chipmunks. Chipmunks are one of those small mammals that both entertain and annoy. Colorful in their brown and white stripes, they are lively and active during the day. When star- tled, they emit a high-pitched “chip” before darting off to a hideout; their low chuck, chuck, chuck is a common summer sound in our woods. They can stuff huge numbers of seeds into their cheek pouches. Despite their prevalence, chipmunks live solitary lives and are highly territorial. In winter, they take a long nap, waking occasionally to eat stored seeds or emerge above ground on a warm winter day. When I was in elementary school, my dad brought home an orphaned flying squirrel. We were enthralled with its large, dark eyes and soft fur. It would curl up in my shirt pocket, and I took it to school for show-and-tell. -

Peer and Partner Comments Received for SGCN: Mammals
Peer and Partner Comments Received for SGCN: Mammals Compiled October 2014 MDIFW’s responses (in blue) to peer and partner comments were provided by Wally Jakubas, Research and Assessment Section, and were reviewed by the respective species specialists and section supervisor. For comments related to the general process for designating species of greatest conservation need, please see the presentations ‘SGCN Process’ from the July 8, 2014 meeting and ‘Revised SGCN Process’ from the September 30, 2014 meeting on Maine’s Wildlife Action Plan revision website (http://www.maine.gov/ifw/wildlife/reports/MWAP2015.html). Please direct any questions to [email protected]. 1. Email from Mac Hunter (7/7/14) I might have listed some other bats based on Criterion 6 --like the three long distant migrants--given the dearth of information. See response to Comment 2 below. 2. Comments from July 8, 2014 break-out group Tree bats are conspicuously absent from the list. There are concerns over the impacts of wind power on these species. All of Maine’s tree bats have been labelled Special Concern (traditionally implying potential ET candidate species) since 1994. MDIFW agrees that all bat species should receive greater attention than they have in the past. Currently, MDIFW is planning to participate in the North American Bat Monitoring program, whose goal is to monitor bat population trends at local, state, regional, and continental levels. This program includes the monitoring of tree bats. The need for monitoring alone does not drive the SGCN ranking process. Given that monitoring will occur for our cave bats, which are proposed for SGCN ranking, we feel that concerns over the population trends of tree bats (i.e., hoary bat [Lasiurus cinereus], silver-haired bat [Lasionycteris noctivagans], and eastern red bat [Lasiurus borealis]), will be met by our overall bat monitoring efforts. -

Small Mammal Survey of the Nulhegan Basin Division of the Silvio 0
Small Mammal Survey of the Nulhegan Basin Division of the Silvio 0. Conte NFWR and the State of Vermont's West Mountain Wildlife Management Area, Essex County Vermont • Final Report March 15, 2001 C. William Kilpatrick Department of Biology University of Vermont Burlington, Vermont 05405-0086 A total of 19 species of small mammals were documented from the Nulhegan Basin Division of the Silvio 0. Conte National Fish and Wildlife Refuge (NFWR) and the West Mountain Wildlife Management Area Seventeen of these species had previously been documented from Essex County, but specimens of the little brown bat (Jr{yotis lucifugu.s) and the northern long-eared bat (M septentrionalis) represent new records for this county. Although no threatened or endangered species were found in this survey, specimens of two rare species were captured including a water shrew (Sorex palustris) and yellow-nosed voles (Microtus chrotorrhinus). Population densities were relatively low as reflected in a mean trap success of 7 %, and the number of captures of two species, the short-tailed shrew (Blarina brevicauda) and the deer mouse (Peromyscus maniculatus), were noticeably low. Low population densities were observed in northern hardwood forests, a lowland spruce-fir forest, a black spruce/dwarf shrub bog, and most clear-cuts, whereas the high population densities were found along talus slopes, in a mixed hardwood forest with some • rock ledges, and in a black spruce swamp. The highest species diversity was found in a montane yellow birch-red spruce forest, a black spruce swamp, a beaver/sedge meadow, and a talus slope within a mixed forest. -
Investigating Evolutionary Processes Using Ancient and Historical DNA of Rodent Species
Investigating evolutionary processes using ancient and historical DNA of rodent species Thesis submitted for the degree of Doctor of Philosophy (PhD) University of London Royal Holloway University of London Egham, Surrey TW20 OEX Selina Brace November 2010 1 Declaration I, Selina Brace, declare that this thesis and the work presented in it is entirely my own. Where I have consulted the work of others, it is always clearly stated. Selina Brace Ian Barnes 2 “Why should we look to the past? ……Because there is nowhere else to look.” James Burke 3 Abstract The Late Quaternary has been a period of significant change for terrestrial mammals, including episodes of extinction, population sub-division and colonisation. Studying this period provides a means to improve understanding of evolutionary mechanisms, and to determine processes that have led to current distributions. For large mammals, recent work has demonstrated the utility of ancient DNA in understanding demographic change and phylogenetic relationships, largely through well-preserved specimens from permafrost and deep cave deposits. In contrast, much less ancient DNA work has been conducted on small mammals. This project focuses on the development of ancient mitochondrial DNA datasets to explore the utility of rodent ancient DNA analysis. Two studies in Europe investigate population change over millennial timescales. Arctic collared lemming (Dicrostonyx torquatus) specimens are chronologically sampled from a single cave locality, Trou Al’Wesse (Belgian Ardennes). Two end Pleistocene population extinction-recolonisation events are identified and correspond temporally with - localised disappearance of the woolly mammoth (Mammuthus primigenius). A second study examines postglacial histories of European water voles (Arvicola), revealing two temporally distinct colonisation events in the UK. -

Leonardo da Vinci envisioned man-flight in the 15th century and designed a practical airplane concept in 1490. Many other pioneers proposed various types of flying machines over the next 400 years but it was not until December 17, 1903 that the Wright Brothers, at Kitty Hawk, NC, were credited with achieving the first manned-powered flight. Over the next 100 years, several factors have influenced advances in aviation. The use of aircraft by European nations in World War I resulted in concern that the U.S. was lagging in aviation developments. This lead to an act of the U.S.
