Coordinated transformation of the gut microbiome and lipidome of bowhead whales provides novel insights into digestion.
Carolyn A. Miller,Henry C. Holm,Lara Horstmann,John C George,Helen F. Fredricks,Benjamin A. S. Van Mooy,Amy Apprill +6 more
TL;DR: The results further elucidate the essential roles that whales and their gastrointestinal microbiotas play in the biogeochemical cycling of carbon and nutrients in high-latitude seas and suggest digestion of wax esters occurred in the mid- to distal small intestine and was correlated with specific microorganisms.
Quantifying variability in stable carbon and nitrogen isotope ratios within the skeletons of marine mammals of the suborder Caniformia
TL;DR: The degree of variability in stable carbon and nitrogen isotope ratios within the skeletons of individual marine mammals was investigated to determine whether any systematic differences in δ 13 C and δ 15 N exist among skeletal elements.

Carbon sources and trophic relationships of ice seals during recent environmental shifts in the Bering Sea.
Shiway W. Wang,Alan M. Springer,Suzanne M. Budge,Lara Horstmann,Lori T. Quakenbush,Matthew J. Wooller +5 more
TL;DR: The findings that sympagic production contributes significantly to food webs supporting ice seals, and that the contribution apparently is less in warm years with low sea ice, raise an important concern: Will the projected warming and continuing loss of seasonal sea ice in the Arctic be compensated for by pelagic production to satisfy both pelagic

Pacific walrus diet across 4000 years of changing sea ice conditions
TL;DR: This paper used stable isotope compositions (δ13C and δ15N) of archaeological, historic and modern Pacific walrus (Odobenus rosmarus divergens) bone collagen to investigate the impacts of changing sea ice conditions on walrus diet during the last ~4000 yr.

Zinc concentrations in teeth of female walruses reflect the onset of reproductive maturity
TL;DR: This novel approach will aid walrus management, and is likely applicable to other species, offering a potentially powerful tool for research, management and conservation of wildlife populations.
