TL;DR: In this paper, the authors present an analysis of 187 time series from primary production to commercial fisheries and nearshore intertidal to offshore oceanic domains demonstrating abrupt changes across trophic levels, with many responses persisting up to at least 5 years after the onset of the marine heatwave.
Mercury Concentrations in Hair from Neonatal and Juvenile Steller Sea Lions (Eumetopias jubatus): Implications Based on Age and Region in this Northern Pacific Marine Sentinel Piscivore

TL;DR: Higher concentrations of mercury were observed in the endangered western population of Steller sea lions and mirrored patterns observed in human biomonitoring studies of Alaskan coastal communities, which have broader implications with respect to human and ecosystem health as StellerSea lions rely on similar prey species and foraging areas as those targeted by commercial fisheries and subsistence users and are therefore valuable sentinels of marine ecosystem health.

Interseasonal and interannual measures of maternal care among individual steller sea lions (eumetopias jubatus)
TL;DR: It is suggested that Steller sea lions reach an upper plateau in duration of foraging cycles as early as mid-August and large increases above that plateau may indicate difficulty finding sufficient food during the winter months.

TL;DR: Estimating the growth rate of vibrissae in fetal, rookery pup, young-of-the-year (YOY), yearling, subadult, and adult SSL found there was high individual variability in these growth rates within each age group.

Assessing killer whale predation on steller sea lions from field observations in kenai fjords, alaska
TL;DR: The behavioral and predatory patterns of Gulf of Alaska (GOA) transient killer whales (Orcinus orca) were studied between 2000 and 2005 using remote video and vessel-based observations near the Chiswell Island Steller sea lion rookery and in the broader Kenai Fjords (KF) region of the northern GOA as mentioned in this paper.
