Blubber fatty acids of gray seals reveal sex differences in the diet of a size-dimorphic marine carnivore. Can. J. Zool. 83(3):377-388.Beck, C. A., Iverson, S. J., and Bowen, W. D. (2005). Blubber fatty acids of gray seals reveal sex differences in the diet of a size-...
We employed a dual‐label radioisotope tracer technique to investigate the potential modification of 22:1n‐11 and its recovery in the blubber of gray seals (Halichoerus grypus) and in the adipose tissue and liver of mink (Mustela vison), a smaller model carnivore also accustomed to fish‐based...
Fatty acids 20:5n3, 22:6n3, 18:1n9 and 18:2n6 have previously been identified as useful indicators of diet in the liver and muscle of deepwater chrondrichthyans85 and in the liver, muscle, and blood of Greenland sharks (Somniosus microcephalus33). January is considered the height of ...
Reliable data on fatty acid composition of carnivore milks are extremely limited. That which is available indicates no synthesis of short-chain fatty acids and only minor amounts of the medium-chain component 12:0 (Table I). The predominant fatty acids are 14:0–18:2. However, only three ...
Tissue expression offads2in brain, gill, intestine, heart, liver and muscle of the studied species is shown in Fig.4. Expression offads2was found in all tissues analysed.S.salpaandP.lascarisshowed the highestfads2expression levels in liver, brain and intestine (Fig.4). A similar pattern ...
desaturase genes (elovl5 and Δ4fad, respectively) in the intestine and liver under the different dietary conditions. The effect of diet- induced changes in gene expression and enzymatic activities was assessed in the FA profile of tissues at the end of the 13-week experimental feeding period...
