A suite of 12 subspecies and species-specific single nucleotide polymorphism (species-specific SNP) markers was developed to distinguish rainbow trout (RT) Oncorhynchus mykiss from the four major subspecies of cutthroat trout: westslope cutthroat trout (WCT) Oncorhynchus clarki lewisi, Yellowstone cutthroat trout (YCT) Oncorhynchus clarki bouvieri, coastal cutthroat trout (CCT) Oncorhynchus clarki clarki, Lahontan cutthroat trout (LCT) Oncorhynchus clarki henshawi, and their hybrids. Several of the markers were linked to help strengthen hybrid determinations, and sex-specific species-specific SNP assays were also developed. [ABSTRACT FROM AUTHOR]

The article presents information on the Canadian Museum of Civilization. It traces out the period of foundation of the museum to it's rich collection, it's architecture, it's thoughtfully done interiors, team of museum staff and other cultural legacy of Canada. The recent happenings in the Canada are also depicted in the museum. The article widely covers, Arrival of Strangers and First People Hall section of the museum. The Museum is reflecting the non-Canadians and the aboriginal perspective as it remains the unresolved issue outside the museum too.

Features African art exhibitions. Exhibit at the British Museum's Sainsbury African Galleries in London, England; 'African Worlds' at the Horniman Museum and Gardens in London; 'African Voices' at the National Museum of Natural History in Washington, D.C.

We used quinacrine hydrochloride and chromomycin A3 staining techniques to examine chromosome-banding polymorphisms in lake trout Salvelinus namaycush from seven wild populations and two hatchery stocks from the Great Lakes region. Although considerable variation in the number of bands occurred among individuals examined by both staining techniques, banding patterns were constant for all cells of a given individual. The populations were differentiated into three groups on the basis of the number of chromomycin A3 bands: a group from the northern shores of Lakes Superior and Huron and the inland lakes north of Lake Superior; a group from the southern shore of Lake Superior; and a group that comprised one wild population and one hatchery stock from Wyoming that were both originally transplanted from a Lake Michigan stock. Each population within these three groups had a unique distribution of chromomycin A3 bands on specific chromosomes. Results for a given population were consistent when sampled for two consecutive years. The populations were very similar in the frequency of Q-band (quinacrine-stained) variants except for one polymorphism found in the Michipicoten Island, Ontario, population and another polymorphism, which was rare in the Seneca Lake, New York, population. The cytogenetic results were compared with allozyme results from the same populations. The populations were similarly differentiated by both the allozyme and cytogenetic data. [ABSTRACT FROM AUTHOR]

Examines the sequence variation in the control region of the mitochondrial DNA to assess the genetic distinctiveness of the short jaw cisco. Sampling of individuals from within the Great Lakes Basin as well as inland lakes outside the basin; DNA fragments containing the entire D-loop that were amplified; Similarity within and among species and shared polymorphism for length variants; Finding that the shortjaw cisco is not genetically distinct from other cisco species.
