Although Vickery and Kevan (1985) provided an exhaustive synopsis of the grasshoppers, crickets and related insects of Canada, some of which can have significant negative economic impact, reference to their distribution maps suggests that Prince Edward Island, and New Brunswick in particular, have been poorly collected for these taxa. More recently...

Nurse practitioners (NPs) are advanced practice nurses who provide holistic care including health promotion and disease prevention to diverse populations across the life span. A current gap in the literature is research that examines NP practice as it relates to lesbian, gay, bisexual, and transgender (LGBT) patients. Individuals who identify as LG...
Porcupine quillwork has long been practiced as a form of self-adornment by the Mi’kmaq peoples. The Mi’kmaq peoples reside on the unceded territory of Mi’kma’ki, the region spanning across what is now known as Nova Scotia, New Brunswick, and Prince Edward Island, as well as parts of Québec, Newfoundland, and Maine. Following the arrival of colonial...
Background
Physical inactivity is an important risk factor for cardiovascular disease (CVD). Atlantic Canada is a region with lower physical activity (PA) levels and poorer CVD outcomes than the rest of Canada. Yet, within-region variation is expected. This study aimed to assess the association between PA and CVD and how this relationship varied on...
Although one of the smaller terrestrial ecozones in Canada, the Atlantic Maritime Ecozone is also one of the more diverse in geology, regional climate, and vegetation. The ecozone encompasses New Brunswick, Nova Scotia, Prince Edward Island, Îles de la Madeleine, and that portion of Quebec extending from the Gaspé Peninsula to the United States bor...

... Since then, reports of new orthopteroid records for the Maritime provinces have appeared in several publications, most notably Catling et al. (2013) with ten new provincial records. Other recent reports include Chandler (1992), Catling et al. (2009), McAlpine (2009, Scudder and Vickery (2010), McAlpine and Ogden (2012), Clements et al. (2013), andMcAlpine et al. (2015). ...
We provide an updated checklist of Orthoptera and their allies for each Maritime province of Canada with details for 21 new species records. Drumming Katydid (Meconema thalassinum), recorded from Nova Scotia (NS) and Prince Edward Island (PEI), and Sprinkled Grasshopper (Chloealtis conspersa), recorded from New Brunswick (NB) are reported for the first time from the Maritimes as a whole. We report range extensions in the Maritime region for Australian Cockroach (Periplaneta australasiae; NB), Treetop Bush Katydid (Scudderia fasciata; NS), Short-legged Camel Cricket (Ceuthophilus brevipes; PEI), Spotted Camel Cricket (Ceuthophilus maculatus; PEI), Roesel’s Shield-backed Katydid (Roeseliana roesellii; NS), and Black-horned Tree Cricket (Oecanthus nigricornis; PEI). Short-winged Mole Cricket (Neoscapteriscus abbreviatus; NB) and European Mole Cricket (Gryllotalpa gryllotalpa; NS) are reported as adventives (non-native species that are believed to be not yet established), new to Canada from the Maritimes. Other new records for species not known to be established are Lined Earwig (Doru taeniatum; NS), Australian Cockroach (Periplaneta australasiae; PEI), American Cockroach (Periplaneta americana; NB), Brown Cockroach (Periplaneta brunnea; PEI), Smooth Cockroach (Nyctibora laevigata; NB), West Indian Leaf Cockroach (Blaberus discoidalis; NB), an unidentified Parcoblatta species (NB), Brown-banded Cockroach (Supella longipalpa; PEI), Praying Mantis (Mantis religiosa; NB), and American Bird Grasshopper (Schistocerca americana; NS).
... The species is a European introduction that apparently entered North America prior to 1952 and since has become widespread in the northeast (Nickle 1984). In NB, Roeseliana roeselii has previously been reported from Albert, Charlotte, Kent, Queens, Victoria, and York counties (McAlpine and Ogden 2012;Catling et al. 2013;McAlpine et al. 2015). The species is clearly widespread in NB, and with additional sampling effort may also be discovered in NS and PE. ...
We present the first reports for Atlantic Canada of the Bush Katydids, Scudderia fasciata Beutenmüller, 1894 and Scudderia septentrionalis (Serville, 1839). The former is associated with conifers, the latter is a deciduous tree specialist (Bland 2003). We also present new distributional records from NB for seven additional species of Tettigoniidae that were previously recorded for the province from a limited number of sites. Specimen records reported here are based on material deposited in the New Brunswick Museum (NBM).
... This suggests that there remains room for further range expansion by Roeseliana roeselii in the Maritimes. Vickery and Kevan (1985), McAlpine (2009), McAlpine and Ogden (2012) and Catling et al. (2013). ...
... Conocephalus brevipennis (Scudder)-NEW BRUNS -WICK: Douglas, York Co., grassy ditch along road, 45.99985, −66.7644, 7 October 2012, D. L. Sabine (New Brunswick Museum). McAlpine and Ogden (2012) reported this species from the Maritimes for the first time, based on specimens collected in Queens County, New Brunswick, in 2008 and 2011. They suggested that the species had previously been overlooked but that records were too few to assess distribution or status. ...
... Our knowledge of the status of this species in the Maritimes remains scanty. This species, called Metrioptera roeselii by Vickery and Kevan (1985), is evidently very well established in New Bruns wick, having been previously reported in Charlotte, Saint John, Queens, and Kent counties (McAlpine 2009;McAlpine and Ogden 2012). Here we add Albert County, in the Caledonia Gorge Protected Natural Area, and York County. ...
Chortophaga viridifasciata, Forficula auricularia, Melanoplus stonei, Scudderia furcata furcata, Scudderia pistillata, and Trimerotropis verruculata from Prince Edward Island and Doru taeniatum, Melanoplus punctulatus, Orchelimum gladiator, and Spharagemon bolli from New Brunswick are new provincial records. Other records of interest include the endemic Melanoplus madeleineae from Île d'Entrée in the Îles-de-la-Madeleine, Quebec; Trimerotropis verruculata from the Îles-de-la-Madeleine, Quebec; and Chortophaga viridifasciata, Stethophyma lineatum, and Tetrix subulata, new for Cape Breton Island, Nova Scotia. The ranges of Conocephalus brevipennis, Tetrix arenosa angusta, Tetrix ornata, and Tetrix subulata are significantly extended in New Brunswick. A previously unpublished record from 2003 of Roeseliana roeselii (Metrioptera roeselii) is the earliest report of this European introduction to the Maritimes.
... The authors suggested that more work was needed to precisely define the distribution and status of Orthoptera species. Recently some of this work was reported by McAlpine et al. (2012). ...
In the last 40 years, the number of species in the orthopteroid orders has increased by ~10% from that known in 1979. The largest order, the Orthoptera, has increased from 205 to 235 species known in Canada. The number of Blattodea has increased from 14 to 18 species, while Dermaptera has increased from 5 to 6 species. The number of species of Mantodea (3) and Phasmida (1) known in Canada have remained unchanged. Most new species records reported in Canada since 1979 have resulted from new collections along the periphery of the range of more widespread species. Some species reported since 1979 are recent introductions to Canada, including species restricted to homes or other heated buildings. The taxonomy of these orders has also changed, with only the Dermaptera having maintained its order definition since the 1979 treatment. Additional orthopteroid species are likely to occur in Canada, particularly in the orders Orthoptera and Blattodea. DNA barcodes are available for more than 60% of the species known to occur in Canada.
