Tamara Harms                                                            Assistant Professor                                    Department of Biology & Wildlife                       Institute of Arctic Biology

Tamara is an ecosystem ecologist and biogeochemist interested in the effects of spatial heterogeneity and hydrologic flowpaths on elemental cycles. She has studied desert riparian zones and streams, urban ecosystems, and boreal and arctic catchments. Her current research focuses on the potential consequences of permafrost loss and climate change for carbon, nitrogen, and phosphorus cycles in high latitude catchments.

Audrey Mutschlecner                                             M.S. student

Audrey is studying decomposition of dissolved organic matter in boreal and arctic streams. She earned a B.A. in environmental studies at Wellesley College. Prior to beginning the M.S. program, Audrey worked as a technician on the SCALER project, studying ecosystem processes in 1st-5th order streams of Caribou-Poker Creeks Research Watersheds.

 

Rebecca Risser                                                       M.S. student

Becca's thesis addresses ammonium uptake in arctic water tracks. She earned a B.S. in Ecology at the University of Georgia. Becca conducted solute addition experiments to determine how redox, flowpath depth, and hydrology influenced efficiency of ammonium retention. Her work was based out of Toolik Field Station.

 

 

 

 

Emily Longano

Emily was a laboratory technician and performed chemical and isotopic analyses. She is currently working at Palmer Station, Antarctica.

 

 

 

 

Sarah "Ludda" Ludwig  

Ludda was a graduate student and research assistant in the lab. She contributed to our project studying the hydrology and biogeochemistry of water tracks based at Toolik Field Station.
