The desman Desmana moschata is a valuable fur-bearing animal of Russian rivers. Numbers were building up until the introduction of the musk-rat from Canada brought a fierce and aggressive competitor for its habitat. The author suggests that the musk-rat is the cause of the decline in the numbers of the desman and is responsible, in at least one lake, for the disappearance of shell-fish, insects, fish, water rats and some breeding birds.
