Investigators at CIRC seek to understand how carbon cycles through aquatic systems. Determining stream trophic status (heterotrophic versus autotrophic) is a tool which may be used to better understand carbon cycling in streams.
In many north temperate and boreal surface waters terrestrial organic matter (tOM) inputs have increased over the past several decades. Increased tOM alters lake ecosystem functions by limiting light and introducing nutrients.
I study aquatic biomechanics: how organisms interact with their fluid environment. I use my background in both organismal biology and fluid physics to study how organisms respond to environmental change, influence ecosystem processes, and impact engineered systems.
My research focuses on urban stream ecology and my current project is focusing on the impact that long culverts (or pipes) have on various aspects of the stream ecosystem including benthic algae, macroinvertebrates, and oxygen dynamics.
Broadly, I am interested in the relationship between lake catchment characteristics and lake ecosystem structure and function, and how this relationship may further our understanding of the contribution of lake ecosystems to biogeochemical cycles.
Having recently graduated from my Master’s degree in Taxonomy & Biodiversity at Imperial College London / Natural History Museum, I jumped at the opportunity to gain first-hand field- and research- experience working on Arctic bumblebee communities on Mt. Nuolja.
The goal of this research is to understand the DIC dynamics in boreal lakes and their impact on net carbon dioxide emission. Arctic and boreal lakes play an influential role in the global carbon cycle.
Sarah Burnet is pursuing her Ph.D. in Fish and Wildlife Sciences at the University of Idaho. Her Ph.D. research is focused on the relationships between sediment type, particle size, iron availability, and dissolved oxygen concentrations in the release of phosphorus.
I am an ecologist and biochemist with a strong interest in northern ecosystems and their responses to climate change. I have been working on geothermally warmed ecosystems in Iceland, unraveling natural long-term warming effects on the ecosystem C and N cycle and on plant physiology.
Currently studying ecology and evolution at Paris-Sud University (France), I am coming to CIRC because I believe that this placement will be a great opportunity to improve my knowledge in ecology and the functioning of arctic ecosystems.
