Estimation of carbon flux to dovekies (Alle alle) in the North Water
We modeled the energy demand of seabirds in the North Water, focusing on the planktivorous dovekie (Alle alle), the dominant species in the polynya. For the dovekie we provided an estimate of carbon flux that included aspects of spatial and temporal variability. We estimated the density, diet, and c...
