Comparing Trophic Level Position Of Invertebrates In Fish And Fishless Lakes In Arctic Alaska, Katie Fisher
Undergraduate Honors Capstone Projects
Arctic lakes are likely very sensitive to the effects of climate change. Thus it is important to understand the current food web dynamics and energy flow within these lakes, to better understand how they will change in the future due to the effects of a rapidly changing climate. In order to contribute to this understanding, my project consists of an analysis of stable isotopes of carbon (delta 13 C) and nitrogen (delta 15 N) from invertebrates among fish and fishless lakes in arctic Alaska, to compare their trophic level positions and primary energetic sources. I collected pelagic invertebrates from 5 …
