Distribution and abundance of the Wilson's snipe in western Canada
1. An extensive field check was made of snipe habitat in those parts of western Canada (excluding most of British Columbia) which are accessible by road. 2. Nesting snipe were found to be very scarce in the whole Short-grass Prairie region, widely distributed and locally common in the Parklands, local and uncommon in the Boreal Forest country, and consistently common in the only area of forest-tu

Studies on avian malaria in vectors and hosts of encephalitis in Kern County, California. I. Infections in avian hosts
An epizoological study of Plasmodium infections in wild birds of Kern County, California, in the years 1946 through 1951 greatly extended knowledge of the occurrence of these parasites and their behavior in nature. Examination of 10,459 blood smears from 8,674 birds representing 73 species resulted in the observation of Plasmodium spp. in 1,094 smears representing 888 individual birds of 27 specie

A comparative study of 28 culture media for Trichomonas gallinae
1. 1. A study was made of the ability of 28 different culture media to support growth of 5 strains of Trichomonas gallinae with their normally associated bacteria. A standard inoculum of 50 protozoa was used, and the cultures were incubated at 35 ?C. Based upon the number of positive cultures obtained, abundance of growth, and number of strains which grew in a given medium, the most satisfactory w

Rodent repellents: Preparation and properties of thiouronium compounds and cyclic imides
Syntheses and bioassays of cyclic imides and thiouronium compounds were carried out as part of a search for materials capable of preventing rodent damage to packaged commodities. Previous studies had shown that repellent activity was associated with functional groups containing nitrogen and sulfur, and was enhanced by the presence of ionic linkages. Twenty-seven thiouronium compounds and 40 imi
