Population-Level Impacts of Natural and Anthropogenic Causes-of-Death for Hawaiian Monk Seals in the Main Hawaiian Islands

In this analysis, we quantify not only the frequency of specific causes‐of‐death (CODs) among main Hawaiian Island monk seals, but also assess the impact of individual CODs on the intrinsic growth rate, λ, of this population.
