Large colonies of two vulnerable, sympatric pinniped species, Peruvian fur seals (Arctocephalus australis Peruvian subpopulation; PFS) and South American sea lions (Otaria byronia; SASL), reside and reproduce in Punta San Juan, Peru (PSJ) where they are exposed to stressors such as environmental contaminants and El Niño-Southern Oscillation (ENSO) events. Cytokine concentrations can be indicative of an animal’s health and immune function by allowing for immunoresponse characterization as Th1 or Th2 dominant. Utilizing an archived pinniped plasma collection of samples from 2009-2019 (n=148), 13 cytokines were analyzed in PFS and SASL: GM-CSF, IFN-γ, KC-like, MCP-1, TNF-α, IL-2, IL-6, …
