The aquatic ecology program studies freshwater, estuarine, and marine ecosystems. Research interests are focused on investigating relationships between water quality, physical habitat, population biology, community ecology, and ecosystem dynamics. Additionally, our Aquatic Ecology lab specializes in monitoring and assessment of Alaska’s waters and diatom and benthic macroinvertebrate processing and identification.
Recent work includes modeling stream temperatures, investigating the relationship between temperature and hydrology and their effect on salmon populations; documenting juvenile salmon diets during their freshwater and estuarine life stages, cataloging diversity of stream biological communities, and surveying the spread of freshwater invasive species. We are also actively involved in characterizing baseline conditions of water quality and physical habitat for freshwater lakes, streams, rivers, and wetlands across the state of Alaska. Our organization also hosts the Alaska Online Aquatic Temperature Site (AKOATS) database, which is a repository of metadata and data for water temperature monitoring sites in Alaska.
Research Focal Areas
Aquatic Projects Map
The Aquatic Projects Map allows users to view locations of freshwater macroinvertebrate and diatom sampling across stream, river, lake, and wetland habitats by ACCS staff across Alaska. Metadata information is provided for each sampling site that includes the project name, year(s) of data collection, the waterbody type, and the types of data collected. The macroinvertebrate and diatom fields indicate whether one or both communities were sampled at a site and the collection method used. Other metadata fields document the availability of additional data types, such as physical habitat measurements, in-situ water chemistry, laboratory water chemistry, and stream discharge. For each project, links are also provided to research reports and datasets (when publicly available). Data from these projects are available upon request by contacting Dan Bogan, email@example.com.
Dan Bogan, M.S.
Aquatic Ecologist | 907-786-4964 | dlbogan (at) alaska.edu
Dan Bogan earned a B.A. in Botany and a M.S. in Environmental Science from Miami University. Dan’s research focuses on biological water quality monitoring using diatom and macroinvertebrate community assemblages. He is also actively involved with tribal watershed and water quality education and training programs.
Aquatic Ecologist | 907-786-6979 | dwmerrigan (at) alaska.edu
Dustin has a B.S. in Environmental Sciences from Alaska Pacific University. Dustin’s research interests are surveying and mapping freshwater habitats to examine juvenile coho salmon diets and macroinvertebrate communities. Most of his work involves aquatic invertebrate taxonomy and geographic information systems.
Becky Shaftel, M.S.
Aquatic Ecologist | 907-786-4965 | rsshaftel (at) alaska.edu
Rebecca has a B.S. in Earth Systems from Stanford University and a M.S. from Baylor University. Becky’s research interests are understanding drivers of aquatic species diversity and distributions in freshwater habitats. Her research focuses on modeling macroinvertebrate, diatom, and fish communities and investigating their relationships to physical habitat and water quality.
Leslie Jones, Ph.D., Alaska Department of Natural Resources
Aquatic Ecologist | (907) 269-8833 | leslie.jones2 (at) alaska.gov | Publications
Leslie received B.S. degrees in Statistics and Environmental Science from North Carolina State University, an M.S. degree in Land Resources and Environmental Science from Montana State University, and a Ph.D. in Systems Ecology from University of Montana. Leslie’s research interests are using computational ecology to understand relationships between climate, biophysical processes, and the landscape. Recent work focuses on how these relationships create suitable freshwater habitat for salmonids and how habitat diversity supports population abundance, productivity, habitat use, and phenology of freshwater organisms.
