Organisms studied
Methods:

Simuliidae larvae were
scrapped from rocks located in the control and fertilized
sections of Kuparuk River. Following collection, larvae
were kept in cold water for several hours, frozen, then
dried. Dried samples were ground to a fine powder and
prepared for stable isotope analysis.

Sampling Description.

None
