Temporary marking of unweaned southern elephant seal (Mirounga leonina L.) pups
Like many pinniped species, southern elephant seals (Mirounga leonina) are conducive to long-term population studies using mark-recapture techniques. The twenty-four year longitudinal dataset at sub-Antarctic Marion Island has already provided much insight into elephant seal population dynamics. How...
