Welcome to the first newsletter for us! We took over the responsibilities from Katie Moriarty in October 2019 and will do our best to fill her shoes. Our goal is to publish a newsletter twice a year in February and August. We welcome any content that you are willing to share including full articles, photos, or new publications. Content may be sent to news- [email protected] We look forward to sending you some great newsletters! Jenny and Stacy

Jenny Kordosky Jenny Kordosky recently received a Master of Science from Utah State University working with Eric Gese. During her thesis she studied the relationship between chron- ic stress and home range disturbance in Pacific fishers located in the Sierra Nevada mountains of California. Currently, Jenny is working towards publishing two manuscripts from her thesis and is employed as a biologist for the Washington Department of Fish and Wildlife in Olym- pia, Washington. Here she is responsible for managing the hatchery data for the en- tire state of Washington and looking to move back into the wildlife realm.

Stacy Cotey

Stacy Cotey is an instructor, academic advisor, and Ph.D. candidate at Michigan Tech- nological University. Her current research is on landscape connectivity and parasite ecology of river in the Upper Peninsula of Michigan. She collaborates with the Michigan DNR Wildlife Disease Lab, Ottawa National Forest, and the Reichard lab at Oklahoma State on the project. Stacy has also worked on and fisher habitat and population projects in the eastern Upper Peninsula and northern Wisconsin. She has a passion for mustelids and is looking forward to contributing to the Martes Working group.

Marten Movement in Fragmented Landscapes Remi Helder, Pauline Hubert, Maden LeBarh, and Marina Mergey

The Centre de Recherche et de Formation en Eco-ethologie (CERFE) team conducted a 4-year research program on the habitat selection pattern of the European pine marten (Martes martes) in very fragmented and low- forested land- scapes in northeastern France. We fitted 25 pine martens (15 Linear fragmentation in 2nd site females, 10 males) with GPS collars on three study sites: one fragmented by a navigation canal, the second by three linear infrastructures (a highway, a canal and a railway) and the third by the almost total loss of the forest habitat, a cereal plain. A total of 199 pathways (1 fix every 5 minutes for 24 hours, once a week) were collected. The analysis of these pathways is ongoing but already con- firms that pine martens can be found in very contrasted land- scapes and are able to move around in inhospitable environ- ments. However, few individuals crossed the different infra-

Marten under anesthesia structures or settled on stable areas. Moreover, most of the present in these three study sites were subadults, which reinforces our hypothesis that these landscapes are of poor quality for the population. We are waiting for further analyses of these data to state more precisely about the im- pact of habitat fragmentation on pine marten populations.

The Martes Working Group, founded in 1993, facilitates communication among scientists with a common interest in re- search, conservation, and management. The Martes complex in- cludes 7 marten species (Martes sp.), fisher (Pekannia pennanti), wolverine (Gulo gulo), and tayra (Eira barbara). Read more at: https://www.martesworkinggroup.org/
