TL;DR: The patterns of mtDNA variation in beluga whales indicated that the summering concentrations are demographically, if not phyletically distinct, while asymmetries in dispersal may be associated with the type of mating system.

TL;DR: In this paper, the authors used regression tree analysis to classify harbor seals and their prey according to their fatty acid signatures and found that large herring and pollock dominated the diet of harbor seals in southern PWS, whereas diets of seals in northern and eastern PWS may have been comprised more of small size classes of herring, and perhaps other items such as cephalopods, sandlance Ammodytes hexapterus, cod Gadus macrocephalus, and shrimp.

TL;DR: Despite individual variation within species, the results indicate that fatty acid signatures accurately characterize forage species in this ecosystem, and consequently can be used to study and perhaps estimate the species composition of diets of their predators.

TL;DR: Analysis of stomach contents of ringed seals collected at eight locations along the Alaskan coast showed significant seasonal and regional differences in diet.

TL;DR: This article used aerial counts to monitor the trend in numbers of harbor seals, Pboca vitulina ricbardsi, in Prince William Sound, Alaska, following the 1989 Exxon Valdez oil spill.
