Elodea mediates juvenile salmon growth by altering physical structure in freshwater habitats
Invasive species introductions in high latitudes are accelerating and elevating the need to address questions of their effects on Subarctic and Arctic ecosystems. As a driver of ecosystem function, submerged aquatic vegetation is one of the most deleterious biological invasions to aquatic food webs. The aquatic plant Elodea spp. has potential to be a widespread invader to Arctic and Subarctic ecosAuthorsMichael P. Carey, Gordon H. Reeves, Suresh Sethi, Theresa L. Tanner, Daniel B. Young, Krista K. Bartz, Christian E. ZimmermaneDNA Metabarcoding Analyses of Diet in Yellow-Billed Loons of Northern Alaska
Environmental DNA is a burgeoning tool used to address wide-ranging scientific questions, including determining diets of difficult-to-sample predators. Loons are large piscivorous diving birds that capture and consume prey underwater, making it nearly impossible to visually determine their diet via observation alone. Identifying species' diets is important for understanding basic life history traiAuthorsDamian M. Menning, Brian D. Uher-Koch, Melanie J. Flamme, Trey Simmons, Joel Schmutz, Sandra TalbotHydrology and geomorphology of the Taiya River near the West Creek Tributary, southeast Alaska
The Taiya River flows through the Chilkoot Trail Unit of Klondike Gold Rush National Historical Park in southeast Alaska, which was founded to preserve cultural and historical resources and further understanding of natural processes active in the surrounding coastal-to-subarctic basin. Riverine processes exert an important influence on ecologically important boreal toad (Anaxryus boreas boreas), sAuthorsJanet H. CurranEnvironmental DNA: An emerging tool for understanding aquatic biodiversity
Field surveys for aquatic organisms provide critical information that is important for robust resource management. However, such surveys are expensive and labor intensive, particularly in large, remote landscapes like those that characterize much of Alaska. Traditionally, characterizing aquatic biodiversity necessitated the physical capture and identification of individual organisms, which requireAuthorsTrey Simmons, Damian M. Menning, Sandra L. TalbotUsing redundant primer sets to detect multiple native Alaskan fish species from environmental DNA
Accurate and timely data regarding freshwater fish communities is important for informed decision-making by local, state, tribal, and federal land and resource managers; however, conducting traditional gear-based fish surveys can be an expensive and time-consuming process, particularly in remote areas, like those that characterize much of Alaska. To help address this challenge, we developed and teAuthorsDamian M. Menning, Trey Simmons, Sandra L. TalbotRapid response for invasive waterweeds at the arctic invasion front: Assessment of collateral impacts from herbicide treatments
The remoteness of subarctic and arctic ecosystems no longer protects against invasive species introductions. Rather, the mix of urban hubs surrounded by undeveloped expanses creates a ratchet process whereby anthropogenic activity is sufficient to introduce and spread invaders, but for which the costs of monitoring and managing remote ecosystems is prohibitive. Elodea spp. is the first aquatic invAuthorsSuresh Sethi, Michael P. Carey, John M. Morton, Edgar Guerron-Orejuela, Robert Decino, Mark Willette, James Boersma, Jillian Jablonski, Cheryl AndersonDetecting and inferring cause of change in an Alaska nearshore marine ecosystem
Community composition, species abundance, and species distribution are expected to change while monitoring ecosystems over time, and effective management of natural resources requires understanding mechanisms contributing to change. Marine ecosystems in particular can be difficult to monitor, in part due to large, multidimensional spatial scales and complex dynamics. However, within the temperateAuthorsH. A. Coletti, James L.

Invasive species introductions in Arctic and Subarctic ecosystems are growing as climate change manifests and human activity increases in high latitudes. The aquatic plants of the genus Elodea are potential invaders to Arctic and Subarctic ecosystems circumpolar and at least one species is already established in Alaska, USA.

Carey, Suresh A Sethi, Sabrina J Larsen, Cecil F RichThe impacts of human recreation on brown bears (Ursus arctos): A review and new management tool
Increased popularity of recreational activities in natural areas has led to the need to better understand their impacts on wildlife. The majority of research conducted to date has focused on behavioral effects from individual recreations, thus there is a limited understanding of the potential for population-level or cumulative effects.
