Moose (Alces alces americana Clinton) blood collected by hunters during the 1977 and 1978 hunting seasons was tested for California group antibodies. Hemagglutination inhibition (HI) tests using snowshoe hare virus (SSH) as antigen yielded 37.02% HI-positive sera. Neutralization tests showed reactors (67.5% positive) to SSH and classified six reactors as Jamestown Canyon virus (JC). This study reports the first finding of JC in a moose population; it also provides the first evidence of JC in Atlantic Canada and supports previous findings of SSH in Nova Scotia.

A large number of North American equine samples were tested for the California group of arboviruses (CAL). Of 861 equine sera tested by hemagglutination inhibition using the snowshoe hare virus as an antigen, 106 (12.3%) were positive. Neutralization tests confirmed antibodies to this virus in 72 of the positive sera. This study provides evidence of CAL activity in the domestic animal population of Nova Scotia.

A serological survey showed antibodies to Francisella tularensis present in 1.55% of snowshoe hares (Lepus americanus struthopus) and 1.06% of moose (Alces alces americana Clinton) sampled in Nova Scotia. No antibody-positive hares were found in Prince Edward Island, however. We believe this to be the first report of antibodies to F. tularensis in the moose.

Sulphur Dioxide Emission

Abstract Twenty-eight rivers in Atlantic Canada are sampled monthly, and have periods of record dating back as far as 1965. Statistical analysis of water chemistry for rivers in areas of Nova Scotia and Newfoundland that are believed to be sensitive to acidification has revealed that pH was significantly lower during the late 1960’s and early 1970’s. Annual hydrogen ion export for selected rivers was also greater during this period. This period of relatively low pH and large hydrogen ion export corresponds to a peak of North American sulphur dioxide emission, suggesting that these rivers may be responding to atmospheric loading of anthropogenic mineral acids.

California Serogroup

ABSTRACTCalifornia serogroup viruses, including Jamestown Canyon virus (JCV) and snowshoe hare virus (SSHV), are mosquito-borne members of theBunyaviridaefamily and are endemic across North America. These arboviruses are potential pathogens which occasionally cause neuroinvasive disease in humans and livestock. A neutralization assay was used to document JCV and SSHV seroprevalence using blood collected from a variety of domestic and wildlife host species. These species were sampled in an island setting, Newfoundland, which contains diverse ecoregions, ecological landscapes, and habitats. Seroprevalence rates for each virus differed significantly among host species and within certain species across different geographic areas. JCV was significantly associated with large mammals, and SSHV was significantly associated with snowshoe hares. Seroprevalence rates in the 5 species of animals tested for prior exposure to JCV ranged from 0% in snowshoe hares to 64% in horses. Seroprevalence rates for SSHV ranged from less than 1% in bovines to 55% in all snowshoe hares. The seroprevalence of SSHV differed significantly (P< 0.05) among hares occupying the discrete habitats of watersheds separated by 14 to 35 km. Cattle on farms in boreal forest landscapes displayed significantly higher JCV seroprevalence (P< 0.001) than those on farms located in seacoast landscapes. Lifelong geographic isolation of cattle to insular Newfoundland was associated with significantly lower JCV seroprevalence (P< 0.01) than that for cattle which had lived off-island.

Economic Relations

This paper contends that the legal precedents which have until so recently discouraged positive Canadian legislation, and which could still invalidate fresh legislative efforts, are based on an outdated view of the economic relations of fishermen and fish buyers. The following briefly examines the economic underpinnings of the Canadian fishermen's right to bar gain, with special reference to Nova Scotia and Atlantic Canada.

AbstractLacconotus punctatus LeConte is reported for the first time from Atlantic Canada from a specimen collected in Bridgewater, Nova Scotia. This is the first record of the family Mycteridae in the region. The bionomics and systematics of the species are briefly discussed. The report is also situated in the context of the developing knowledge of saproxylic beetles in the region.

This research/performance text emerged from a study involving internationally educated female teachers who have immigrated to Atlantic Canada. The text features the words and artwork of the research participants as well as excerpts from newspapers, academic writing, and documents about immigration in Nova Scotia juxtaposed so as to foreground the complexity of the women's immigration and integration experiences. Introductory comments provide contextual information about the research project, the participants, and the evolution of, as well as rationale for, the text as performance piece.

This journal examines privateering and naval prizes in Atlantic Canada in the maritime War of 1812 - considered the final major international manifestation of the practice. It seeks to contextualise the role of privateering in the nineteenth century; determine the causes of, and reactions to, the War of 1812; determine the legal evolution of prize law in North America; discuss the privateers of Nova Scotia and New Brunswick, and the methods they utilised to manipulate the rules of prize making during the war; and consider the economic impact of the war of maritime communities. Ultimately, the purpose of the journal is to examine privateering as an occupation in order to redeem its historically negative reputation. The volume is presented as six chapters, plus a conclusion appraising privateering, and seven appendices containing court details, prize listings, and relevant letters of agency.

AbstractSeven species of introduced Carabidae are newly reported in Nova Scotia and Prince Edward Island. Trechus quadristriatus (Schrank), Amara ovata (Fabricius), and Harpalus rubripes (Duftschmid) are newly recorded in Atlantic Canada as a whole. Possible modes of introduction of these species to the region are discussed. Several may have been introduced in association with dry ballast shipments. Some may have arrived via natural dispersion from neighbouring areas; others appear to have been present and undetected for a considerable time. The possible impact of such introductions is also discussed. Synanthropic environments have higher proportions of introduced species than relatively undisturbed, native habitats. Some adventive species do become widespread in native environments; however, negative impacts on native species may not be readily apparent.
