A method of marking larval lampreys
Roland L. Wigley
1952, Copeia (1952) 203-204
Biological investigations of lamprey populations in central New York have indicated a need for developing a method of marking larvae of the sea lamprey, Petromyzon marinus Linnaeus, and the American brook lamprey, Lampetra lamottei (Lesueur) Since lamprey larvae live in burrows in the soft sediments of the stream bottom, the...
Hybridization of Canada geese with blue geese in the wild
H.K. Nelson
1952, The Auk (69) 425-428
While carrying out hunter bag checks in the vicinity of Sand Lake National Wildlife Refuge, Columbia, South Dakota, during the 1950 waterfowl hunting season, the author examined two adult male geese which proved to be crosses between one of the smaller Canada Geese (possibly Richardson's Goose, Branta canadensis hutchinsi) and...
Origin of the Mima Mounds, Thurston County region, Washington
R. C. Newcomb
1952, Journal of Geology (60) 461-472
There has been recent favorable consideration of the idea that the Mima mounds were made by gophers. The writer believes the evidence indicates that gophers function only in the reworking of the mound material, not in the primary construction. The plausibility of the earlier glacial or periglacial theory has been...

Further studies on factors determining tissue levels of sulfamerazine in trout
S. F. Snieszko, S. B. Friddle
1952, Transactions of the American Fisheries Society (81) 101-110
There is considerable variation in the tissue level of sulfamerazine among individual trout in a treated population. This fact may be the reason why prolonged sulfonamide therapy sometimes fails to free all trout from Bacterium salmonicida. The quantity of food given with a standard dosage of sulfamerazine has a pronounced...
