Reconstructing habitat use by juvenile salmon sharks links upwelling to strandings in the California Current

The salmon shark Lamna ditropis is an important apex predator of North Pacific ecosystems. Juveniles use 2 nursery areas, the North Pacific Transition Zone (NPTZ) and the California Current System (CCS) Like many other slow-growing, longlived marine species, salmon sharks have a relatively high juvenile survival elasticity value, an index of the importance of juvenile survival to population growth rate This indicates that survivorship of this age class is important in maintaining the viability of salmon shark populations Hence, it is important to understand how juvenile salmon sharks use their nursery areas.
