Notes | Understanding the diets of different species is essential for wildlife managers. Managers need to know what is eaten and when and where it is consumed. This paper contributes to our understanding of the diet of harbor seals by reviewing over eighty years of scientific literature on this topic. Seasonal and spatial variations in diet are noted, and the issue of harbor seal predation on salmonids is explored. The article is available by contacting the authors through ResearchGate. |
