MINNESOTA MUSTELIDS Young
By Blane Klemek MINNESOTA MUSTELIDS Young Naturalists the Slinky,Stinky Weasel family ave you ever heard anyone call somebody a weasel? If you have, then you might think Hthat being called a weasel is bad. But weasels are good hunters, and they are cunning, curious, strong, and fierce. Weasels and their relatives are mammals. They belong to the order Carnivora (meat eaters) and the family Mustelidae, also known as the weasel family or mustelids. Mustela means weasel in Latin. With 65 species, mustelids are the largest family of carnivores in the world. Eight mustelid species currently make their homes in Minnesota: short-tailed weasel, long-tailed weasel, least weasel, mink, American marten, OTTERS BY DANIEL J.

The Scientific Basis for Conserving Forest Carnivores: American Marten, Fisher, Lynx and Wolverine in the Western United States
United States The Scientific Basis for Conserving Forest Carnivores Department of Agriculture Forest Service American Marten, Fisher, Lynx, Rocky Mountain and Wolverine Forest and Range Experiment Station in the Western United States Fort Collins, Colorado 80526 General Technical Report RM-254 Abstract Ruggiero, Leonard F.; Aubry, Keith B.; Buskirk, Steven W.; Lyon, L. Jack; Zielinski, William J., tech. eds. 1994. The Scientific Basis for Conserving Forest Carnivores: American Marten, Fisher, Lynx and Wolverine in the Western United States. Gen. Tech. Rep. RM-254. Ft. Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 184 p. This cooperative effort by USDA Forest Service Research and the National Forest System assesses the state of knowledge related to the conservation status of four forest carnivores in the western United States: American marten, fisher, lynx, and wolverine. The conservation assessment reviews the biology and ecology of these species. It also discusses management considerations stemming from what is known and identifies information needed. Overall, we found huge knowledge gaps that make it difficult to evaluate the species’ conservation status. In the western United States, the forest carnivores in this assessment are limited to boreal forest ecosystems. These forests are characterized by extensive landscapes with a component of structurally complex, mesic coniferous stands that are characteristic of late stages of forest development. The center of the distrbution of this forest type, and of forest carnivores, is the vast boreal forest of Canada and Alaska. In the western conterminous 48 states, the distribution of boreal forest is less continuous and more isolated so that forest carnivores and their habitats are more fragmented at the southern limits of their ranges. -

Campbell, School of Veterinary Medicine, University of California, Davis, One Shields Avenue, Davis, CA 95616 Perrine, Campbell and Green R5-FR-010 August 2010 NOTES IN PROOF • Genetic analyses by B. Sacks and others 2010 (Conservation Genetics 11:1523-1539) indicate that the Sacramento Valley red fox population is native to California and is closely related to the Sierra Nevada red fox. They designated the Sacramento Valley red fox as a new subspecies, V. v. patwin. • In August 2010, as this document was going to press, biologists on the Humboldt-Toiyabe National Forest detected a red fox at an automatic camera station near the Sonora Pass along the border of Tuolomne and Mono Counties. Preliminary genetic analyses conducted at UC Davis indicate that the fox was a Sierra Nevada red fox. Further surveys and analyses are planned. • The California Department of Fish and Game Region 1 Timber Harvest Program has established a Sierra Nevada red fox information portal, where many management-relevant documents can be downloaded as PDFs.

American Marten, Fisher, Lynx, and Wolverine: Survey Methods for Their Detection Agriculture
United States Department of American Marten, Fisher, Lynx, and Wolverine: Survey Methods for Their Detection Agriculture Forest Service Pacific Southwest Research Station Abstract Zielinski, William J.; Kucera, Thomas E., technical editors. 1995. American marten, fisher, lynx, and wolverine: survey methods for their detection. Gen. Tech. Rep. PSW-GTR-157. Albany, CA: Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture; 163 p. The status of the American marten (Martes americana), fisher (Martes pennanti), lynx (Lynx canadensis), and wolverine (Gulo gulo) is of increasing concern to managers and conservationists in much of the western United States. Because these species are protected throughout much of their range in the west, information on population status and trends is unavailable from trapping records. This report describes methods to detect the four species using either remote photography, track plates, or snow tracking. A strategy for systematic sampling and advice on the number of devices used, their deployment, and the minimum sampling duration for each sampling unit are provided. A method for the disposition of survey data is recommended such that the collective results of multiple surveys can describe regional distribution patterns over time. The report describes survey methods for detection only but also provides some considerations for their use to monitor population change.

Distribution of American Black Bear Occurrences and Human–Bear Incidents in Missouri
Distribution of American black bear occurrences and human–bear incidents in Missouri Clay M. Wilton1,3, Jerrold L. Belant1,4, and Jeff Beringer2 1Carnivore Ecology Laboratory, Forest and Wildlife Research Center, Mississippi State University, Box 9690, Mississippi State, MS 39762, USA 2Missouri Department of Conservation, 3500 E Gans Rd., Columbia, MO 65202, USA Abstract: American black bears (Ursus americanus) were nearly extirpated from Missouri (USA) by the early 1900s and began re-colonizing apparent suitable habitat in southern Missouri following reintroduction efforts in Arkansas (USA) during the 1960s. We used anecdotal occurrence data from 1989 to 2010 and forest cover to describe broad patterns of black bear re-colonization, human–bear incidents, and bear mortality reports in Missouri. Overall, 1,114 black bear occurrences (including 118 with dependent young) were reported, with 95% occurring within the Ozark Highlands ecological region. We created evidentiary standards to increase reliability of reports, resulting in exclusion of 21% of all occurrences and 13% of dependent young. Human–bear incidents comprised 5% of total occurrences, with 86% involving bears eating anthropogenic foods. We found support for a northward trend in latitudinal extent of total occurrences over time, but not for reported incidents. We found a positive correlation between the distribution of bear occurrences and incidents. Twenty bear mortalities were reported, with 60% caused by vehicle collisions. Black bear occurrences have been reported throughout most of Missouri’s forested areas, although most reports of reproduction occur in the southern and eastern Ozark Highlands. Though occurrence data are often suspect, the distribution of reliable reports supports our understanding of black bear ecology in Missouri and reveals basic, but important, large-scale patterns important for establishing management and research plans. -

Terrestrial Wildlife
Science Synthesis to Support Socioecological Resilience in the Sierra Nevada and Southern Cascade Range Section 7—Terrestrial Wildlife wide range of terrestrial wildlife species inhabit the synthesis area. This sec- A tion of the report focuses on three of those species: two forest carnivores, the fisher Pekania( pennanti) and the Pacific marten Martes( caurina), and one raptor, the California spotted owl (Strix occidentalis occidentalis). Recent taxonomic revi- sions have changed the scientific names of the fisher and marten in California. The fisher was formerly known as M. pennanti (Sato et al. 2012), and the Pacific marten, found in western North America, was formerly classified with the American marten (M. americana), which now refers to martens in eastern North America (Dawson and Cook 2012). Chapter 7.1, “The Forest Carnivores: Marten and Fisher,” describes the ecology and context of fisher and marten, summarizing population trends, iden- tifying threats, and highlighting science-based implications for the management of their habitats. Chapter 7.2, “California Spotted Owl: Scientific Considerations for Forest Planning,” describes the ecological context, population trends, and habitat needs of this top predator, highlighting recent findings on the effects of forest management, wildfire, and other important ecological stressors. Several aquatic species of concern to management, including native trouts and amphibians, are addressed in chapters 6.1 “Water and Stream Ecosystems,” and 6.4, “Lakes: Recent Research and Restoration Strategies.” Munton Tom The species in this section are not the only ones that could be affected by management actions, but they have been priorities for conservation in the synthesis area because of ecological and social factors. -

The Pacific Northwest has experienced intensive logging during the past century and the distribution of martens in this region is largely discontinuous because of fragmented patches of forest cover (Gibilisco 1994). Based on state agency harvest data, the average annual number of martens harvested in the Oregon Cascades (and statewide) has decreased substantially during recent decades, but disentangling the potential factors (e.g., decreasing abundance, decreasing harvest effort) attributed to changes in harvest levels continues to prove difficult (Hiller 2011, Hiller et al. -
