Dryocoetes krivolutzkajae Mandelshtam (Coleoptera: Curculionidae), a scolytine bark beetle previously known only from the Kamchatka Peninsula, Russia was discovered in Labrador and New Brunswick, Canada. It is unknown whether the Canadian populations represent an introduction or the natural range of D. krivolutzkajae. The habit of this beetle is particular because it is one of the few scolytines that complete their lifecycle within herbaceous roots. This species feeds on the rhizomes of Rhodiola rosea Linnaeus (Crassulaceae) an important natural medicinal plant. Currently it is unknown if, and how rhizome infestation affects the active chemical constituents. The impact of D. krivolutzkajae on the quantity and quality of R. rosea rhizomes requires study.
Background: The medicinal plant Rhodiola (Rhodiola rosea), while valuable as an adaptogen in the global trade of natural health products, is not currently commercially sourced in eastern Canada. Rhodiola grows prolifically along the coast of Labrador (Canada), including rocky shorelines, sandy beaches, and up to the high tidal zone.Nunatsiavut Inuit in these remote areas have traditionally used Rhodiola as food and medicine; however, due to globalization and significant cultural changes, these communities are shifting from traditional activities towards new ventures. The cultivation of local Rhodiola presents an opportunity for a sustainable, community-based enterprise with economic and social benefits. It is critical to consider the unique local context when developing an enterprise intended to build capacity in participating communities as cultural context is a key factor determining the success of community-based enterprises.Methods: To explore the potential for development of a natural health product based upon Labrador Rhodiola, semi-structured interviews and focus groups were conducted with Nunatsiavut Inuit Elders, youth, and community members.Results: Participants reported both medicinal and food uses of the local Rhodiola, as well as unique insights into its growth and conservation. They were enthusiastic at the prospective social, economic, and health benefits of a community-based enterprise centered on cultivation and marketing of local Rhodiola, but concerned about the potential for over-harvesting, and wanted to ensure conservation of local populations.Conclusions: A community-based enterprise centered on local Rhodiola cultivated in Nunatsiavut could benefit Nunatsiavut Inuit communities but would need to meet biocultural design criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
