- Abstract
Because adult SSL vibrissae are much more robust compared to pups and subadults, it is possible to laterally split each vibrissae section into two portions, allowing for analysis of stable isotopes and mercury from the same growth period (Amy Bishop, personal communication, August 2022). Using a direct mercury analyzer to measure mercury in vibrissae of Steller sea lions For most of the length of the vibrissae, multiple vibrissae from a single animal show the same general trend in [THg], although there was less agreement near the root and towards the fine tip of the vibrissae. Studies that measure stable isotopes in vibrissae tend to exclude the base/root portion of the vibrissae, as it has been demonstrated to be a fundamentally different tissue type than the remaining portion of the keratinized whisker (Beltran et al., [3]; Lübcker et al., [17]).
