Stranding trends of Steller sea lions Eumetopias jubatus 1990-2015
Endangered Species Research, 2019 Distinct population segments of Steller sea lion (SSL) Eumetopias jubatus have experienced different population trends over the last 5 decades, rendering the need for retrospective study. By identifying long-term stranding trends of SSLs we can develop a

The effects of birth weight and maternal care on survival of juvenile Steller sea lions (Eumetopias jubatus). [PDF]
PLoS ONE, 2014 Steller sea lions were listed as endangered following a collapse of the western distinct population beginning in the late 1970s. Low juvenile survival has been implicated as a factor in the decline.

Physiological predictors of long-term survival in juvenile Steller sea lions (Eumetopias jubatus). [PDF]
Conserv Physiol, 2015 This study builds on a continued effort to document potential long-term research impacts on the individual, as well as to identify potential markers of survival for use in a field framework. The Transient Juvenile Steller sea lion (TJ) project was developed as a novel framework to gain access to wild individuals.

Entanglement rates and haulout abundance trends of Steller (Eumetopias jubatus) and California (Zalophus californianus) sea lions on the north coast of Washington state. [PDF]
PLoS ONE, 2020 Entanglements affect marine mammal species around the globe, and for some, those impacts are great enough to cause population declines. This study aimed to document rates and causes of entanglement and trends in local haulout abundance for Steller and ...

Population Trend and Elasticities of Vital Rates for Steller Sea Lions (Eumetopias jubatus) in the Eastern Gulf of Alaska: A New Life-History Table Analysis. [PDF]
PLoS ONE, 2015 Steller sea lion (Eumetopias jubatus) numbers are beginning to recover across most of the western distinct population segment following catastrophic declines that began in the 1970s and ended around the turn of the century.

Diving behavior of immature Steller sea lions (Eumetopias jubatus) [PDF]
, 2003 Understanding the ontogenetic relationship between juvenile Steller sea lions (Eumetopias jubatus) and their foraging habitat is key to understanding their relationship to available prey and ultimately their survival. We summarize dive and movement data from 13 young-of-the-year (YOY) and 12 yearling Steller sea lions equipped with satellite dive ...

Neonatal growth of Steller sea lion (Eumetopias jubatus) pups in Alaska [PDF]
, 2005 The growth rate of Steller sea lion (Eumetopias jubatus) pups was studied in southeast Alaska, the Gulf of Alaska, and the Aleutian Islands during the first six weeks after birth. The Steller sea lion population is currently stable in southeast Alaska but is declining in the Aleutian Islands and parts of the Gulf of Alaska. Male pups (22.6 kg [±2.21 SD]

Diets of Steller sea lions (Eumetopias jubatus) in Southeast Alaska, 1993−1999 [PDF]
, 2007 The diet of Steller sea lions (Eumetopias jubatus) was determined from 1494 scats (feces) collected at breeding (rookeries) and nonbreeding (haulout) sites in Southeast Alaska from 1993 to 1999. The most common prey of 61 species identified were walleye pollock (Theragra chalcogramma), Pacific herring (Clupea pallasii), Pacific sand lance (Ammodytes ...
