Wolves are back: Sociopolitical identity and opinions on management of Canis lupus
Gray wolves (Canis lupus) were eliminated from the state of Oregon in the middle of the 20th century. By the early 21st century, wolves had returned to the northeast corner of the state, dispersing from populations reintroduced in Idaho and Wyoming. On a series of random‐sample telephone surveys (2011–2018), we asked more than 3,000 northeast Oregon residents about their preferences concerning wolf management strategies. One‐third of the respondents said that wolves should be eliminated from this region. Sociopolitical identity dominated other individual characteristics including age, education, years resident, and forestland ownership in predicting wolf‐management views. Political effects appear even stronger when our indicator distinguishes the most conservative, and further intensify when most of the respondent's friends belong to the same party. This strong influence of sociopolitical identity echoes findings from the broader literature on environmental concern, but adds a new and policy‐relevant element to wolf‐attitude research. As wolves expand throughout the west, and new states consider reintroduction, state and federal wildlife managers face deeply rooted opposition. Managers must consider a range of strategies to manage wolves while working with community leaders in wolf‐occupied areas to determine management options.

Development of a mitochondrial DNA marker that distinguishes domestic dogs from Washington state gray wolves
We describe a primer pair that amplifies a 203 base pair fragment containing 4 single nucleotide polymorphisms (SNPs) within the
cytochrome b
region of the mitochondrial DNA that, when sequenced, conclusively distinguishes Washington state gray wolves from domestic dogs. The method is more efficient and cost-effective than other established methods for genetically distinguishing domestic dogs from gray wolves when using potentially degraded scat samples. Further testing may find that the SNP panel is also applicable to studies in Oregon, Idaho, Montana, and Wyoming, as these wolves belong to the same distinct population segment as Washington state gray wolves.

Shifting environmental concern in rural eastern Oregon: the role of demographic and place-based factors
Public opinion can impact the success of natural resource management policies and programs. In this case study, we assess the degree to which demographic and place-based factors are associated with changing public opinions on climate change, wolves, renewable energy, and land development regulations in rural northeast Oregon. Based on cross-sectional telephone survey data collected in 2011 and 2014, our observations suggest declining support for eliminating wolves, increased support for renewable energy, and increasingly favorable views of regulations that limit development in rural landscapes. We find that while demographic change and local events contribute to some of the observed shifts in opinion on wolves, exogenous factors acting at state and national levels likely contribute to shifting opinions on climate change, renewable energy, and land use regulations.

Polyphyletic ancestry of historic gray wolves inhabiting U.S. Pacific states
Given the recent re-colonization of gray wolves (
Canis lupus
) to the Pacific northwest, USA, and subsequent migration into northern California, understanding how well natural migration has restored historic diversity can inform management decisions. In this study, we report the mitochondrial DNA control region haplotypes of nine museum specimens that curators identified as
C. lupus
from Oregon, Nevada, and California. Among the nine samples currently available for genetic analysis of historic genetic diversity of
C. l.
spp. in the U.S. Pacific states, we found six previously described haplotypes including two domestic dog (
C. l. familiaris
) haplotypes. Notably, we present the first evidence of Mexican wolf (
C. l. baileyi
) ancestry in southern California while the northern Californian specimen, as well as one individual from Nevada, present a haplotype common to wolves from the historic American West and extant Canadian wolf populations. Finally, the three Oregon specimens shared a haplotype that is only observed in extant wolves from coastal British Columbia (the “coastal rainforest” wolf ecotype), indicating that the historical range of this haplotype reached as far south as southwestern Oregon. In conclusion, our results indicate that the genetic composition of historic wolf populations in the Pacific northwest and southwest states was polyphyletic and included wolves that share maternal ancestry with current populations from adjacent regions. These findings, in addition with future nuclear analyses, reveal more accurate historic range delimitations, which is critical information when designing appropriate management plans for wolves naturally re-colonizing the U.S. Pacific northwest and southwest regions.

Non-Invasive Survey of Forest Carnivores in the Northern Cascades of Oregon, USA
Several species of forest carnivores are of state or federal concern in Oregon and are or may be sensitive to timber management practices, wildfires, climate change, and other large-scale disturbances. We implemented a non-invasive survey of forest carnivores in the northern Cascades of Oregon during fall–spring, 2012–2014. We collected 111,148 images from 21 elevated and 39 ground-level baited camera stations located from 586 to 2237 m in elevation. We detected (≥1 image) Red Fox (Vulpes vulpes) at 9 ground stations, of which 4 also detected Coyote (Canis latrans). We detected American Marten (Martes americana) at 63% of all stations (elevation range = 1252–2237 m), including 5 of 7 stations located in areas that experienced wildfires since 1996 that covered >5000 ha. Other forest carnivores detected included Bobcat (Lynx rufus), Black Bear (Ursus americanus), Mountain Lion (Puma concolor), Northern Raccoon (Procyon lotor), American Mink (Neovison vison), weasel (Mustela spp.), and skunk (Mephitis mephitis, Spilogale gracilis); but we did not detect Wolverine (Gulo gulo), Canada Lynx (Lynx canadensis), Fisher (Martes pennanti), or Gray Wolf (Canis lupus). Future periodic non-invasive surveys of forest carnivores may provide information about changing species composition and distribution, especially in relation to climate change, vegetation succession, and potential recolonization by Gray Wolves.

Oregon's Wandering Wolf, OR-7, Gets Official Pack Status
\"Oregon's famous wandering wolf, OR-7, is now officially the leader of his own pack. State and federal wildlife agencies said...they have designated OR-7, his mate and their pups the Rogue Pack, for their location in the Rogue River drainage in the Cascades east of Medford.\" (Statesman Journal) Read about this wolf pack in Oregon.

A numerical analysis of flavonoid variation in Arnica subgenus Austromontana (Asteraceae)
Species of Arnica subgenus Austromontana produce a total of 23 leaf flavonoids, including simple and methylated flavone and flavonol glycosides as well as highly methylated flavone aglycones and a 6-hydroxylated flavone. Most of the taxa exhibit considerable interpopulational variability, with the number of compounds per population ranging from 2 to 14. Analysis of flavonoid variation in 113 populations representing all 9 species of the subgenus was carried out using cluster analysis, principal components analysis, and binary discriminant analysis. Results indicate the flavonoid profile of the very rare A. viscosa is the most distinctive in the subgenus Although exhibiting considerable interpopulational variability, all populations of A. gracilis, a hybrid taxon, form a very distinct and cohesive group, supporting its recognition at the specific level. Additionally, chemical diversification from A. cordifolia has taken place largely in the Klamath region of Oregon and California. The range of variability exhibited by A. cordifolia is reflected in these Klamath region derivatives.
