Abstract The centipede fauna of Canada is reviewed based on information available in the literature and on examination of some material, and provincial and territorial distributions are provided. About 53 species are known from Canada, representing four orders: Scutigeromorpha (1), Scolopendromorpha (5), Geophilomorpha (19), and Lithobiomorpha (28). British Columbia has the most recorded species (23), followed by Ontario (17) and Newfoundland and Labrador (12). Arctogeophilus glacialis (Attems) and Alaskobius adlatus Chamberlin are newly reported from Canada (Northwest Territories), Schendyla nemorensis (Koch) is newly reported from Ontario, and Lithobius forficatus (Linnaeus) is recorded for the first time from New Brunswick and Prince Edward Island. Arctogeophilus melanonotus (Wood) is removed from the list of Canadian species.

This checklist of the oribatid fauna of Canada and Alaska (excluding Astigmata) includes 580 identified species in 249 genera and 96 families. The known fauna of Canada includes 556 identified species in 247 genera, and that of Alaska includes 182 species in 95 genera; 39 of the 42 oribatid superfamilies are represented. We further list ~ 300 species that are currently unidentified, and possibly undescribed. In addition, we list 42 genera that are represented only by unidentified and probably undescribed species. For each species we give combinations and synonymies, specific locations in Alaska and the Provinces and Territories of Canada, habitats, and biogeography.                There are 182 identified species known for Alaska, 152 for Yukon, 122 for Northwest Territories, 58 for Nunavut; 210 for British Columbia, 213 for Alberta, 15 for Saskatchewan, 84 for Manitoba, 167 for Ontario, 210 for Québec, 110 for Nova Scotia, 77 for New Brunswick, 84 for Newfoundland and 6 for Prince Edward Island. The known fauna of Canada is smaller than that of Austria, and is approximately equivalent to that of the Czech Republic. As these countries are much smaller in size than Canada and less ecologically diverse, we consider the Canadian and Alaskan fauna are at most 25% known. The paucity of these data reflects the absence of taxonomic and faunistic studies on Oribatida in State, Provinces or Territories, and especially in the Canadian and Alaskan National Park systems and the hundreds of Provincial Parks.                Despite the almost 90% increase in described species since the catalogue of Marshall et al. (1987), there is a need for focussed, coordinated research on Oribatida in the natural regions throughout Canada and Alaska, and for monographs on families and genera with large numbers of undescribed species, such as Brachychthoniidae, Damaeidae, Cepheidae, Liacaridae, Oppiidae, Suctobelbidae, Hydrozetidae, Phenopelopidae, Scheloribatidae, Haplozetidae and Galumnidae.

AbstractEight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes: Crataraea suturalis (Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and “Meotica pallens (Redtenbacher)” (Ontario, British Columbia) belong to Oxypodini; Atheta (Chaetida) longicornis (Gravenhorst) (Nova Scotia, Quebec), Atheta (Thinobaena) vestita (Gravenhorst) (New Brunswick), Dalotia coriaria (Kraatz) (Alberta), Dinaraea angustula (Gyllenhal) (Nova Scotia, Prince Edward Island, Quebec, Alberta), and Nehemitropia lividipennis (Mannerheim) (New Brunswick, Nova Scotia, Prince Edward Island, Quebec, Ontario) belong to Athetini; and Homalota plana (Gyllenhal) (Nova Scotia, New Brunswick) belongs to Homalotini. These species have likely been introduced into Canada from Europe by various anthropogenic activities, and their bionomics and possible modes of introduction are discussed. For each species, a short diagnosis and habitus and genital images are provided to assist with identification. The habitus and genital images are presented here for the first time for these species in North America. New United States records are not included in the abstract.

Butternut Canker

In June 1997, butternut canker was found for the first time in New Brunswick, Canada, at Stickney, Carleton County. A fungal isolate recovered from a young branch canker on butternut (Juglans cinerea L.), cultured on potato dextrose agar, produced spores and cultural morphology as previously described (1). This strain was retained as FSC-758 in the Fredericton Stock Culture Collection at the Atlantic Forestry Centre. The disease was also detected at four other locations in Carleton County along the Saint John River watershed within 20 km of the State of Maine. One stem canker examined at Peel, Carleton County, suggests the disease has been present at this site in New Brunswick for at least 7 years. The butternut tree is at the northeastern edge of its natural range in New Brunswick and, prior to the pathogen's detection, was believed to be far enough from infected butternut in the northeastern United States, Ontario, and Quebec to escape infection. Because planted specimens of butternut exist outside the tree's natural range in New Brunswick and in the neighboring provinces of Nova Scotia and Prince Edward Island, efforts are underway to determine how far the fungus has spread in the Maritime Provinces.

OBJECTIVE: To characterize the patient population served by Atlantic Canada’s Multi-Organ Transplant Program liver transplant service over the first five years of activity in its current iteration.METHODS: Data from a prospective institutional database, supplemented by retrospective medical record review, were used to identify and characterize the cohort of patients assessed for consideration of first liver transplant between December 1, 2004 and December 1, 2009.RESULTS: In the five-year period after reactivation, the program assessed 337 patients for first liver transplant. The median age at referral for this group of 199 men (59.0%) and 138 women (41.0%) was 56.1 years (range 16.3 to 72.3 years). The leading three liver diseases indicating liver replacement were alcohol-related end-stage liver disease (20.5%), hepatocellular cancer (16.6%) and hepatitis C-related end-stage liver disease (14.0%). When evaluated according to provincial population-standardized incidence, significant differences in the incidence of liver transplant assessment among the four Atlantic Canadian provinces were found (per 100,000 inhabitants: Nova Scotia 19.8, New Brunswick 13.0, Newfoundland and Labrador 9.1 and Prince Edward Island 11.0; Fisher’s exact P<0.001). Of the 337 individuals who began the assessment process, 153 (45.4%) were assigned to the wait list. The probability of an individual being assigned to the wait list was not found to differ according to province of residence (Nova Scotia 45.3%, New Brunswick 40.0%, Newfoundland and Labrador 58.7% and Prince Edward Island 40.0%; Fisher’s exact P=0.206).CONCLUSIONS: The analysis suggests that there are geographical disparities in access to liver transplantation in Atlantic Canada. These disparities appear to be related to factors that precede the transplant assessment process.

AbstractThe Tenebrionidae of the Maritime Provinces of Canada are surveyed. Forty-eight species have been reported from the region. Eleven of these species (ten Palearctic and one Nearctic) have been introduced to the region, five of which are apparently now extirpated. Dates of first detection of these species are provided for each province and North America. Thirteen species are newly recorded in New Brunswick, 25 in Nova Scotia, and 15 on Prince Edward Island, for a total of 53 new provincial records. Of these, 18 species including Bolitophagus corticola Say, Neatus tenebrioides (Palisot de Beauvois), Helops gracilis Bland, Blapstinus substriatus Champion, Hymenorus obesus Casey, Hymenorus picipennis Casey, Hymenorus pilosus (Melsheimer), Mycetochara bicolor (Couper), Mycetochara binotata (Say), Mycetochara fraterna (Say), Platydema excavatum (Say), Platydema teleops Triplehorn, Corticeus praetermissus (Fall), Alobates pennsylvanicus (DeGeer), Haplandrus fulvipes (Herbst), Xylopinus saperdioides (Olivier), an undescribed species of Paratenetus Spinola, and an undescribed species of Neatus LeConte are newly recorded for the Maritime Provinces as a whole. One of these, Helops gracilis, is recorded for the first time in Canada. The fauna is discussed from the perspective of the patterns of distribution of species in the region and their possible underlying causes. Island faunas are discussed, as is the saproxylic component of the fauna, with a brief consideration of the importance of this trophic group in the dynamics of forest ecosystems in the region.

About 80 million acres on the mainland of the Northwest Territories and Yukon, and over 40 million acres on the Arctic islands, are under oil and gas exploration permit. Exploration permits were issued in the Arctic islands for the first time in June 1960, following promulgation in April of new Canada Oil and Gas Regulations for federal government lands. The issue of these permits extended the northern oil and gas search from the Alberta and British Columbia borders, in lat. 60° N., northward to the Arctic islands; in terms of land area this is one of the most widespread oil and gas searches in the world. The Arctic islands exploration also holds particular interest since it is the farthest north oil and gas exploration ever carried out.

AbstractThe fauna of introduced rove beetles (Staphylinidae) in the Maritime Provinces of Canada is surveyed. Seventy-nine species have now been recorded. Of these, 73 have been found in Nova Scotia, 29 on Prince Edward Island, and 54 in New Brunswick. Twenty-five species are newly recorded in Nova Scotia, 16 on Prince Edward Island, and 10 in New Brunswick, for a total of 51 new provincial records. Of these, 15 species, Tachinus corticinus Gravenhorst, Mycetoporus lepidus (Gravenhorst), Habrocerus capillaricornis (Gravenhorst), Aleochara (Xenochara) lanuginosa Gravenhorst, Gnypeta caerulea (C.R. Sahlberg), Atheta (Microdota) amicula (Stephens), Cordalia obscura (Gravenhorst), Drusilla canaliculata (Fabricius), Deleaster dichrous (Gravenhorst), Coprophilus striatulus (Fabricius), Carpelimus subtilis (Erichson), Leptacinus intermedius Donisthorpe, Tasgius (Rayacheila) melanarius (Heer), Neobisnius villosulus (Stephens), and Philonthus discoideus (Gravenhorst), are newly recorded in the Maritime Provinces. Two of these, Atheta (Microdota) amicula and Carpelimus subtilis, are newly recorded in Canada. Leptacinus intermedius is removed from the faunal list of New Brunswick and Philhygra botanicarum Muona, a Holarctic species previously regarded as introduced in North America, is recorded for the first time in the Maritime Provinces. An examination of when species were first detected in the region reveals that, on average, it was substantially later than comparable dates for other, better known families of Coleoptera — an apparent indication of the comparative lack of attention this family has received. Some introduced species appear to be associated with the dry-ballast mechanism of introduction to the continent, while others are synanthropic and may have been inadvertently introduced in connection with agriculture, horticulture, or other processes associated with human activities. A substantial number are now established and well distributed, seemingly indicative of an early introduction into the region, the ability to successfully colonize a habitat and disperse within it, or a combination of these factors. Other species appear to be local in distribution, perhaps indicative of more recent introductions, more restricted ecological tolerances, a lesser ability to disperse, or a combination of these factors. These recent discoveries are discussed briefly in the context of the importance of taxonomic research and ongoing monitoring in order to detect and identify exotic species and monitor for new introductions and changes in existing native or introduced populations — all important in terms of assessing the risk of introductions to, and their impact on, native faunas and habitats.

AbstractThe Canadian species of the genus Placusa Erichson are reviewed. Eight species are recorded, of which four constitute new Canadian records (P. despecta Erichson, P. incompleta Sjöberg, P. petulans Casey, and P. vaga Casey) and two are new to science (P. pseudosuecica Klimaszewski sp.nov., and P. canadensis Klimaszewski sp.nov.). Placusa turbata Casey, one of the two species previously recorded from British Columbia, is here considered a synonym of P. tachyporoides (Waltl) and is reported for the first time from eastern Canada (New Brunswick, Ontario, Quebec). New data are provided on the systematics, distribution, bionomics, and relationships of selected North American species. A key to the species occurring in Canada is presented with illustrations of the median lobe of the aedeagus, spermatheca, male tergite 8, antennae, and outline drawings of the head and adult forebody for each species. Selected Palearctic species are also illustrated for easy comparison with the closely related Nearctic species. The Canadian distribution is presented on contour maps, and world distribution is discussed for all species. The following lectotypes are designated for the Nearctic species which were described from more than one specimen without former holotype designation: Casey (1893, 1911): P. frosti, P. strata, P. tacomae, P. turbata; Erichson (1840): P. despecta; and Sachse (1852): Oxypoda minuta Sachse. Oxypoda minuta is transferred to the genus Placusa and newly synonymized with P. despecta Erichson (1840).

Unique Species

Trichomycetes, an ecological grouping of fungi and protists associated with the guts of aquatic arthropods, are distributed globally. The diversity of this unique species complex is, however, more completely documented in some parts of the USA and Europe than in Canada. Twenty species of trichomycetes were collected from insect hosts at six sites in Prince Edward Island, situated in the Gulf of St. Lawrence about 14 km off the east coast of New Brunswick. Five new species of Harpellales (Fungi, Kickxellomycotina), Caudomyces longicollis Strongman sp. nov. from Antocha sp. (Tipulidae), Legeriomyces minae Strongman sp. nov. from mayflies, and Smittium ditrichosporum Strongman sp. nov., Smittium insulare Strongman sp. nov., and Smittium tynense Strongman sp. nov. from chironomids are described. Smittium brevisporum L.G. Valle & Santam. and Smittium gracilis L.G. Valle & Santam., previously known only from Spain, are recorded for the first time in North America. A number of species of Harpellales and Amoebidiales (Phylum Mesomycetozoa) previously recorded from the region (P.E.I. and N.S.), and several that are common and widely distributed, were also recovered. Stachylina pedifer Lichtw. & M.C. Williams was collected from chironomids in a stream exposed to seawater during high tide. Trichomycete diversity is high on P.E.I., as it is in many regions where extensive surveys have been conducted, including islands such as Australia and New Zealand. More data from islands may help shed some light on distribution patterns for these obligate endobionts and provide some insights into mechanisms for dispersal.
