Natural Resources Preservation Program Active

By Alaska Science Center December 3, 2020

This is a nation-wide collaborative program, supported by the USGS Ecosystems Mission Area, through which USGS and National Park Service staff address priority research needs identified by the National Park Service.  On this page, we highlight research taking place in Alaska as part of this program.

Return to Ecosystems >> Collaborative Science for Priority Information Needs

National Park Service priorities change annually through this program and results of past studies can be found under Data and Tools and Publications on this page.

For 2022-2024, the USGS is focusing on the following science needs identified by the National Park Service Alaska Region:

  • Development of an Alaska-specific fish DNA sequence library to inform monitoring of resident and invasive species in multiple national parks of Alaska
  • Effects of nest predation and predator abundance on habitat quality for declining passerines breeding in Denali National Park
  • Effects of glacial inputs on nearshore marine communities in Kenai Fjords National Park and Preserve
  • Tracing mercury through lake food webs in Alaska's national parks
  • Streamflow quantification at National Creek, Kennecott Mines National Historic Landmark, Wrangell-St. Elias National Park and Preserve
  • Analysis of genetic variation in wolves from Denali National Park and Preserve and Yukon-Charley Rivers National Preserve, Alaska

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 ecos

eDNA 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 trai

Hydrology 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), s

Environmental 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 require

Using 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 te

Rapid 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 inv

Detecting 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 temperate

A primer on potential impacts, management priorities, and future directions for Elodea spp. in high latitude systems: learning from the Alaskan experience

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. To illustrate the problems of preventing, eradicating, containing, and mi

The 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. Brown bears (Ursus arctos) are the focus of a growing wildlife
