Statement of Research:

I study the conservation biology, behavioral ecology, and population and community ecology of amphibians, reptiles, and fishes. My current projects address: 1) the effects of forest management practices and riparian buffer widths; 2) microhabitat- to landscape-scale habitat modeling; and 3) threats including diseases, invasive species, climate change, and fire.

Projects & Activities:

Adult Cope's Giant Salamander (Dicamptodon copei). Photo by L.L.C. Jones Conservation Assessments for Pacific Northwest US Species Species of concern listed as US Forest Service Region 6 ‘Sensitive Species’ and Bureau of Land Management Oregon/Washington ‘Special Status’ are managed under the Interagency Special Status and Sensitive Species Program (ISSSSP). Species-specific “Conservation Assessments” are developed to provide a synthesis of current biological and ecological knowledge, as well as known or suspected threats and effects of management activities. New information is often available per species, such as the compilation and map of species localities in the northwest area. Assessments provide guidance about management considerations and outline research and monitoring needs; their intent is to help manage for species to forestall losses and preclude listing under the US Endangered Species Act. For some species, the ISSSSP has funded projects to understand species distributions, habitat associations, or effects of management. Reports of these studies and Conservation Assessments are available on the ISSSSP Web site, in the amphibian index: http://www.fs.fed.us/r6/sfpnw/issssp/species-index/fauna-amphibians.shtml I have contributed to the Conservation Assessments of the following amphibian species: Aneides flavipunctatus- Black Salamander (ANFL) Batrachoseps attenuatus - California Slender Salamander (BAAT) Batrachoseps wrighti - Oregon Slender Salamander (BAWR) Dicamptodon copei - Cope's Giant Salamander (DICO) Plethodon larselli - Larch Mountain Salamander (PLLA) Plethodon stormi - Siskiyou Mountains Salamander (PLST) [note: this species also has a tri-agency ‘Conservation Strategy’ with US FWS, published as Northwest Fauna 6] Plethodon vandykei - Van Dyke's Salamander (PLVA) Ascaphus montanus - Rocky Mountain Tailed Frog (ASMO) Rana boylii - Foothill Yellow-legged Frog (RABO) In addition, Conservation Assessments have been developed by others for these species, and are available at the ISSSSP link above: Rana luteiventris - Columbia Spotted Frog (RALU) Rana pretiosa - Oregon Spotted Frog (RAPR) Rhyacotriton olympicus - Olympic Torrent Salamander (RHOL) Rhyacotriton cascadae - Cascade Torrent Salamander (RHCA)
Ranavirus Reporting System Ranavirus is an OIE-notifiable emerging infectious disease associated with amphibian losses; it also affects fish and reptiles. Ranavirus is relatively poorly understood, and there is a need to enhance communications among researchers and managers. In cooperation with world Ranavirus experts, we are helping to create a Ranavirus Reporting System. The Global Ranavirus Consortium (GRS: https://www.ranavirus.org/) facilitates communication and collaboration among scientists, veterinarians, and others interested in ranaviruses. The GRS website provides resources including an open-access Ranavirus book and symposium information. Ranavirus General Information: "The Rise of Ranavirus", Gray and Miller 2013 Global patterns of Ranavirus detections: Brunner et al. 2021	RRTH = Relocation, Reintroduction, Translocation, and Headstarting These are stop-gap measures for rare species conservation. To promote communication of lessons learned from past and ongoing projects, photos and information on existing projects is being compiled. An update to Reintroduction information will be initiated in 2022 by Partners in Amphibian and Reptile Conservation. We welcome assistance to update information on Relocation, Translocation, and Headstarting efforts. Read more
