Polish Issues in Canada During World War I The article presents the impact of World War I on Polish immigrants in Canada, the position of the Polish ethnic group in this country and the efforts of persons of Polish descent in regard to recruitment for the Polish Army in North America. Poles, who were subjects of Germany or the Austro-Hungarian Empire were treated as enemy aliens. Those people were forced to register and report to the police on a regular basis and some of them were interned in labour camps during the war. Some were released from the camps after an intervention of Polish organizations and priests. Soldiers of Polish descent, volunteers and recruits also fought in the Canadian Expeditionary Forces in Europe. Over 20,000 Polish volunteers from the US (including over 200 from Canada) enrolled in a training camp formed in Niagara-on-the-Lake, Ontario on the border with the US. The problems with the organization and functioning of the camp, and opinions on Polish volunteers shaped the attitude of many Canadians towards the Polish diaspora and the newly established Polish state. Keywords: World War I, Polish Diaspora in Canada, Niagara-on-the-Lake camp, Haller’s Army, Colonel Arthur D’Orr LePan Streszczenie Artykuł przedstawia kilka przykładów obrazujących oddziaływanie wydarzeń I wojny światowej na żyjących w Kanadzie polskich imigrantów, pozycję polskiej grupy etnicznej w tym kraju oraz na aktywność osób polskiego pochodzenia na rzecz rekrutacji do wojska polskiego w Ameryce Północnej. Polaków, którzy byli poddanymi Niemiec lub monarchii austro-wegierskiej traktowano jak przedstawicieli państw wrogich. Mieli obowiązek rejestracji i regularnego zgłaszania się na policję a niektórzy zostali internowani w stworzonych w czasie wojny obozach pracy. Część z nich była z tych obozów zwolniona po interwencji polskich organizacji i polskich duchownych. Żołnierze polskiego pochodzenia, zarówno ochotnicy jak i poborowi, znaleźli się także w oddziałach Kanadyjskich Sił Ekspedycyjnych walczących w Europie. Ponad 20 tys. polskich ochotników z USA (w tym ponad 200 z Kanady) zgłosiło się też do obozu szkoleniowego utworzonego w Niagara-on-the-Lake, Ontario, przy granicy z USA. Problemy z organizacją i funkcjonowaniem tego obozu oraz opinie o polskich ochotnikach, kształtowały nastawienie wielu Kanadyjczyków do polskiej grupy etnicznej i nowotworzonego Państwa Polskiego.

Round whitefish (Prosopium cylindraceum) have a broad, disjunct range across northern North America and Eurasia, and little is known about their genetic population structure. We performed genetic analyses of round whitefish from 17 sites across its range using nine microsatellites, two mitochondrial DNA (mtDNA) loci, and 4918 to 8835 single-nucleotide polymorphism (SNP) loci. Our analyses identified deep phylogenetic division between eastern and western portions of the range, likely indicative of origins from at least two separate Pleistocene glacial refugia. Regionally, microsatellites and SNPs identified congruent patterns in subdivision, and population structure was consistent with expectations based on hydrologic connectivity. Within the Laurentian Great Lakes, Lake Huron and Lake Ontario were identified as key areas of interest. Lake Huron appears to be a contemporary source population for several other Great Lakes, and Lake Ontario contains a genetically discrete group of round whitefish. In all cases, multiple genetic markers yielded similar patterns, but SNPs offered substantially enhanced resolution. We conclude that round whitefish have population subdivision on several scales important for understanding their evolutionary history and conservation planning.

Samples of threespine stickleback, Gasterosteus aculeatus L., collected from several areas of Newfoundland and Nova Scotia, and single sites from Iles de la Madeleine, Quebec, and eastern Lake Ontario, were analyzed for variation in numbers of anterior lateral plates and vertebrae. Counts of vertebrae varied from 28 to 35 and mean counts from 30.3 to 33.4, without being related to any obvious geographic gradients. Trunk and caudal segments of the vertebral column had about the same degree of variation. Counts of lateral plates exclusive of ossicles of the caudal keel ranged from 0 to 31 with a range of means from 1.6 to 24.7. Incomplete development of potential plate number and absence of caudal keels were observed in 1st-year individuals. These results are discussed in relation to information about this species complex from populations of Pacific North America and Europe.
