Impact of Tusk Anomalies on the Long-Term Foraging Ecology of Narwhals. [PDF]
Ecol EvolWe combined stable δ13C and δ15N isotope analysis and genetic sexing to investigate whether narwhals with dental anomalies have a distinct long‐term foraging ecology. Our results showed no difference in stable isotope signature of two‐tusked male and one‐tusked female narwhals relative to normal‐tusked narwhals, indicating that an extra tusk does not ...
