Fatty acid composition of the adipose tissue of six carnivorous=20
mammalian species (European otter Lutra lutra, American mink Mustela=20
vison, European Mink Mustela lutreola, European polecat Mustela=20
putorius, stone marten Martes foina and European wild cat Felis=20
silvestris) was studied. These species forage to differing degrees in=20
aquatic and terrestrial food webs. Fatty acid analysis revealed=20
significant differences in polyunsaturated fatty acid composition=20
between species. More specifically, our results underline a gradual=20
significant decrease in the docosahexaenoic acid (DHA)/linoleic acid=20
(LNA) ratio of carnivore species as their dependence on aquatic food=20
webs decreases. In conclusion, the use of the DHA/LNA ratio in long-
term studies is proposed as a potential proxy of changes in foraging=20
behaviour of semi-aquatic mammals.

(Studies of European polecats in various regions have differed in what=20
is eaten and in what percentages, with the amounts also varying by=20
season. It would be interesting to see where and when the polecats=20
came from. Still, this looks like a useful approach to find when=20
observations may fail.)
