Factors Affecting Nesting Success Of The Canvasback In The Aspen Parklands, Jerome H. Stoudt

USGS Northern Prairie Wildlife Research Center

The Minnedosa study area is located in the southwestern portion of Manitoba just south of the town of Minnedosa. It is 90 square miles in size and roughly square in shape. The Aspen Parkland, in which the study area is located, is characterized by gently rolling terrain and black soils. Mixed farming is the rule with emphasis on small grain production consisting of wheat, barley, and oats. Roughly 50 percent of the water areas in the parkland are ringed with aspen, Populus tremuloides, and large blocks of aspen are interspersed throughout the area. The Minnedosa area differs because of …

The Coccidian Parasites (Protozoa, Sporozoa) Of Rodents, Norman D. Levine, Virginia Ivens

Harold W. Manter Laboratory: Library Materials

This monograph summarizes the known information on taxonomy, morphology, life cycle, hosts, location in the host, pathogenicity, geographic distribution, and cross-transmission studies of the 196 named species of coccidia of rodents. These include 176 species of Eimeria, 9 of Isospora, 3 of Wenyonella, 2 each of Cryptosporidium and Klossiella, and 1 each of Dorisiella, Caryospora, Tyzzeria, and Klossia. In addition, similar data are given for those forms for which insufficient information is available to justify assigning them names.

Eimeria, which is the most common genus, has been described from only 15% …

Jane Claire Dirks-Edmunds Documents

This article, which was published in volume 39 issue 4 of the journal Northwest Science, describes a study that began in the fall of 1959 and was supported by federal grant G-8779. Dr. Jane Claire Dirks-Edmunds's research focused on the little-known Bronze Beetle and involved several of her contemporaries, both within and outside the Linfield College Biology Department.

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

Report On A Visit To Israel August-September 1964, D J. Carder

Soil conservation survey collection

The main features in which farming methods and the environment in Israel differ from those in Western Australia, as they appeared to me, are:- the dominant sedimentary and limestone geology with its accompanying soil and moisture conditions population pressure which puts a premium on agricultural productivity and research the widespread use of sprinkler irrigation. These factors interact in various ways so that, although many problems are similar in the two countries (both have many pioneering problems remaining) the approaches to them vary considerably.
