PhD Opportunity in Biogeochemistry of Beaver-Created Ecosystems at University of Connecticut, United States
Researchers interested in freshwater ecology, ecosystem science, climate change, and biogeochemistry have an exciting opportunity to join a funded Ph.D. project at the University of Connecticut (UConn). The Helton and Lawrence laboratory groups are seeking a motivated doctoral student to investigate how beaver-created ecosystems influence freshwater carbon cycling throughout the northeastern United States. This interdisciplinary research opportunity focuses on understanding how beaver ponds, wetlands, and modified stream networks affect:
- Greenhouse gas emissions
- Ecosystem metabolism
- Carbon storage
- Watershed-scale carbon dynamics
- Freshwater ecosystem functioning
The selected student will join a collaborative research team and receive a Graduate Assistantship with funding of approximately $38,000 per year, with support available up to $40,000 per year. The anticipated start dates are between January and June 2027. Applications will be reviewed until the position is filled, with priority consideration given to applicants who apply by September 1, 2026.

About the Research Project
Beavers are increasingly recognized as important ecosystem engineers because their dam-building activities transform landscapes and create new aquatic habitats. By altering stream networks and creating ponds and wetlands, beavers can significantly influence:
- Carbon storage
- Nutrient cycling
- Greenhouse gas production
- Water availability
- Ecosystem productivity
However, the full role of beaver-created ecosystems in regional carbon cycling remains an important scientific question. This Ph.D. project will investigate how these ecosystems contribute to freshwater carbon dynamics and how their effects scale from individual ponds to entire watersheds.
Research Focus Areas
The doctoral student will contribute to a broader interdisciplinary project examining freshwater carbon processes. Major research activities include:
Greenhouse Gas Dynamics
The student will measure and analyze greenhouse gas processes in beaver-created environments. Research may include:
- Carbon dioxide flux measurements
- Methane emissions analysis
- Seasonal greenhouse gas monitoring
- Environmental drivers of gas production
These findings will improve understanding of how freshwater ecosystems contribute to regional climate processes.
Ecosystem Metabolism
The project will examine how beaver-created habitats function biologically. The student may investigate:
- Primary production
- Community respiration
- Energy flow
- Biological activity within ponds, wetlands, and streams
This research will help explain how ecosystem engineering influences freshwater productivity.
Carbon Storage Assessment
A major goal of the project is understanding carbon storage within beaver-created ecosystems.
Research activities may include evaluating:
- Organic carbon accumulation
- Sediment carbon pools
- Wetland carbon retention
- Long-term ecosystem carbon dynamics
Watershed-Scale Modeling
The student will have opportunities to develop approaches for modeling beaver ecosystem carbon dynamics at larger spatial scales. Potential approaches include:
- Ecological modeling
- Spatial analysis
- Watershed carbon assessments
- Data-driven ecosystem predictions
This provides valuable training at the intersection of field ecology and quantitative environmental science.
Research Environment
The successful applicant will join the Helton and Lawrence research groups at the University of Connecticut. The project brings together expertise in:
- Freshwater ecosystem ecology
- Environmental biogeochemistry
- Climate-related ecosystem processes
- Watershed science
- Ecological modeling
Students will work as part of a collaborative research environment focused on understanding how natural ecosystem processes influence environmental change.
Field Research Opportunities
This Ph.D. position includes significant field-based ecological research. The student will conduct fieldwork in freshwater ecosystems, including:
- Beaver ponds
- Wetlands
- Streams
- Watershed environments
Field activities may involve:
- Water quality sampling
