The Common

In Canada, the Common Eastern Bumble Bee (BombusimpatiensCresson) is native to southern Ontario and Quebec, but since being developed as a managed commercial pollinator, it has been exported to several other provinces for use in greenhouse and field crop settings. This has enabled this species to become established outside its natural range and it is now established in eastern Canada (New Brunswick, Nova Scotia, Prince Edward Island) and British Columbia. To date, the species has not been detected via field capture in the prairie provinces.Here we report on recent captures ofB.impatiensworkers and males from south-eastern Alberta and suggest that these specimens escaped from nearby commercial greenhouses. The risk that the presence and looming establishment of this species has on native bumble bees in the Canadian prairies is discussed.

Total Fauna

The diplopod fauna of eastern Canada, an area containing all or parts of Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland, consists of 6 orders, 15 families, 28 genera, and 38 species. Eighteen species, 47% of the total fauna, are synanthropic forms introduced chiefly from Europe, and 11 additional millipeds, including another order and family, may occur there, particularly in southern Ontario. The sole Canadian records of Polyzonium mutabile Causey, Aniulus paludicolens Causey, Uroblaniulus stolidus Causey, Pseudopolydesmus branneri (Bollman), Scytonotus granulatus (Say), and Pleuroloma flavipes Rafinesque; the genera Cleidogona, Scytonotus, and Pleuroloma; and the family Cleidogonidae are from Ontario. Pleuroloma flavipes and Uroblaniulus stolidus, in Essex and Algoma counties, are newly recorded from Canada. Polyxenus lagurus (L.), Underwoodia iuloides (Harger), and Trichopetalum lunatum Harger are the only native diplopods in the Maritime Provinces, and Allajulus caeruleocinctus (Wood), a Palearctic introduction, is the only species known from New Brunswick and Prince Edward Island. The combination Polyzonium cryptocephalum (McNeill) is revived for the dominant eastern polyzoniid species, and Petaserpes rosalbus Cope and Polyzonium divaricatum Loomis are recognized as synonyms of it, the latter being new. Other new synonymies are Polyzonium borealis Loomis and P. quadricauda Loomis with P. mutabile Causey; Julus immaculatus Wood and Parajulus dux Chamberlin with Uroblaniulus canadensis (Newport); and Underwoodia polygama Cook and Collins with U. iuloides. Apheloria virginiensis (Drury), n.comb., is proposed as are subspecific statuses for the common eastern spirobolid millipeds. American species improbable for eastern Canada are identified, and a key to known and potential taxa and pertinent anatomical drawings are provided.

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.

Early in the present century the balsam woolly aphid, Adelges piceae (Ratz.), was introduced accidentally into North America. The history of its development and spread in the United States and Canada has been described by Balch (1952). At the present time, the adelgid occurs in eastern Canada over approximately the southern half of New Brunswick with an extension of the range in the extreme northeastern part of the Province, throughout Nova Scotia and Prince Edward Island, and in some areas of the southwestern and southeastern parts of Newfoundland.

Observation Period

An observation of the flight of a flock of Common Eiders, Somateria mollisima, on 24 October 2012 suggests that, 15 years after construction of the Confederation Bridge connecting New Brunswick and Prince Edward Island (12.9 km in length over the Northumberland Strait), the bridge may still be a partial barrier to bird flight and possibly migration. Although we believe the Common Eiders we observed intended to fly over or under the bridge, none of the 44 Common Eiders crossed the structure during the observation period.

The larch sawfly, Pristiphora erichsonii (Htg.), is a serious defoliator of trees of the genus Larix and particularly of Larix laricina (Du Roi) K. Koch in eastern Canada. According to Reeks (1954), four outbreaks occurred in the Maritime Provinces between 1883 and 1942. Following the last outbreak, few specimens of the insect were found in New Brunswick, Nova Scotia, and Prince Edward Island until 1960 when an outbreak started near Fredericton, New Brunswick. Since, outbreaks varying in degree from moderate to severe have persisted throughout this province.In the course of a study on the ecology and population dynamics of the insect it was found necessary to verify and separate the various developmental stages of the larvae.

Insight Into

AbstractThe Carboniferous record of tetrapod footprints is mostly of Euramerican origin and provides the basis for a footprint biostratigraphy and biochronology of Carboniferous time that identifies four tetrapod footprint biochrons: (1) stem-tetrapod biochron of Middle Devonian-early Tournaisian age; (2) Hylopus biochron of middle-Tournaisian-early Bashkirian age; (3) Notalacerta-Dromopus interval biochron of early Bashkirian-Kasimovian age; and (4) Dromopus biochron of Kasimovian-early Permian age. Particularly significant is the Carboniferous tetrapod footprint record of the Maritimes basin of eastern Canada (New Brunswick, Nova Scotia and Prince Edward Island), which encompasses well-dated and stratigraphically superposed footprint assemblages of Early Mississippian-early Permian age. The Carboniferous tetrapod footprint record provides these important biostratigraphic datums: (1) oldest temnospondyls (middle Tournaisian); (2) oldest reptiliomorphs, likely anthracosaurs (middle Tournaisian); (3) oldest amniotes (early Bashkirian); and (4) oldest high fiber herbivores (Bashkirian). Carboniferous tetrapod footprints thus provide significant insight into some major events of the Carboniferous evolution of tetrapods.

Lowbush Blueberry

Spiraea latifolia (Ait.) Borkh., broad-leaved meadowsweet (Rosaceae), is a weed of pastures, lowbush blueberry (Vaccinium angustifolium Ait. and V. myrtilloides Mich.) fields and cranberry (V. macrocarpon Ait.) bogs of Eastern Canada, especially where soil moisture content is high during the growing season. Where S. latifolia occurs, other vegetation is lacking or depressed. Much time is lost in harvesting lowbush blueberries due to jamming of the S. latifolia stems among the tines of the rake or in cranberries due to mechanical damage to the harvesters. In Canada, S. latifolia occurs in Newfoundland, Prince Edward Island, Nova Scotia, New Brunswick, Quebec, Ontario, and Manitoba.
