Thanks to the influence of a powerful US senator, more than $120 million has been pumped into research on Alaska's endangered Steller sea lions in just four years. Rex Dalton asks what we've learned.

Endangered species, threatened fisheries: Science to the rescue! Evaluating the Congressionally designated Steller Sea Lion Research Program
Between 2001 and 2004, the US Congress designated over $120 million for research on the western population of Steller sea lions. This paper evaluates the science program, summarizing its context and
Regulating a complex adaptive system via its wasp-waist: grappling with ecosystem-based management of the New England herring fishery
TLDR
The New England herring fishery is used as an example of the unresolved scientific issues pertinent to ecosystem-based management of forage-fish fisheries, and a dichotomy in management choice between promoting an ecosystem dominated by valuable groundfish resources and promoting the current ecosystem that features a large herring resource.
Animal-rights group sues over ‘disturbing’ work on sea lions
TLDR
Conservation effort criticized for branding pups, but experts say it could help protect endangered pups from extinction.
High Natality Rates of Endangered Steller Sea Lions in Kenai Fjords, Alaska and Perceptions of Population Status in the Gulf of Alaska
TLDR
A longitudinal study of natality among individual Steller sea lions at a rookery and nearby haulouts in Kenai Fjords, Gulf of Alaska during 2003–2009 suggested that females which gave birth had a higher probability of surviving and giving birth in the following year compared to females that did not give birth, indicating some females are more fit than others.
Crossing to safety: dispersal, colonization and mate choice in evolutionarily distinct populations of Steller sea lions, Eumetopias jubatus
TLDR
It is demonstrated that resource limitation may trigger an exodus of breeding animals from declining populations, with substantial impacts on distribution and patterns of genetic variation, and revealed that this event is rare because colonists dispersed across an evolutionary boundary.
Animal welfare and decision making in wildlife research
TLDR
By judicious application of the principles outlined in Bateson’s Decision Cube, conservation scientists can effectively and clearly highlight the benefits of their work and more successfully engage the public in the complex debate about the value of conservation research to protecting ecosystem function, ecosystem services and evolutionary potential.
Sea-lion studies come to a halt after court judgement
TLDR
The US government blocks ‘hot branding’ of pups in what’s thought to be a first for the country.
International comparison of fisheries management with respect to nature conservation
In dit rapport worden enkele voorbeelden besproken van visserijen die zodanig zijn gereguleerd dat geen significante schade wordt aangericht aan het ecosysteem. De leidende vraag is in feite of
Complex research on sea lions is worth the expense
TLDR
2003 UB313 should be called the tenth planet, because it is both larger than Pluto and at an appreciably different distance, although a practical problem the IAU will then have to face is where to draw the line at the lower end of sizes.
Reflected Stochastic Differential Equation Models for Constrained Animal Movement
TLDR
Methods for simulation and inference based on augmenting the constrained movement path with a latent unconstrained path are presented and illustrated with a simulation example and an analysis of telemetry data from a Steller sea lion in southeast Alaska.

Night-time predation by Steller sea lions
TLDR
New insight into the feeding habits of these mammals will help conservation attempts to protect them from extinction.
Digestive efficiency and dry-matter digestibility in Steller sea lions fed herring, pollock, squid, and salmon
TLDR
Steller sea lions appear to digest prey of high energy density more efficiently than prey of low energy density, and DE measures are more meaningful than DMD in conveying the energetic benefits derived by sea lions from dif- ferent types of prey.
