Seven kinds of tardigrades, not before reported for Canada, are identified from sites in south central New Brunswick. They are Echiniscus (Echiniscus) spiniger, E. (E.) spinuloides, Macrobiotus ambiguus, M. furciger, M. hibernicus, Hypsibius (Diphascon) nodulosus, and H. (D.) pinguis brunsvicensis which is proposed as a new variety. A summary of species and varieties of tardigrades so far known for Canada is given. Markings on the pharyngeal tube of species of Diphascon are discussed.

We report on 2 first records of Chironomidae for Ontario, Rheosmittia spinicornis (Brundin, 1956) and Sublettea coffmani (Roback 1975), and confirm a previous record of Odontomesa fulva (Kieffer 1919) from Ontario. Specimens of S. coffmani have been only reported from New Brunswick whereas R. spinicornis has records from northern, western and central provinces and territories. Reports of O. fulva were not con-firmed in Ontario. Here we report its occurrence for the second time in south central Ontario, confirming its occurrence within the province.

Semi Arid

Two contiguous successions within Member B of the Westphalian Clifton Formation are exposed on the coast of Chaleur Bay east of Bathurst, New Brunswick. The upper succession is dominated by sandstone, and the lower by shale, which encloses isolated channel and lenticular sandstone bodies. Distinctive features of the shale are thin coals, casts of tree trunks, calcareous paleosols, and deep desiccation cracks with calcareous coatings. Markov chain analysis of the shale-dominated succession defines a repetitive sequence of shale, rippled fine-grained sandstone, paleosol, and coal. This sequence is attributed to filling of flood basins followed by emergence and pedogenesis under semi-arid conditions, which prevented thick coal accumulation. The major sandstone bodies are interpreted as channels, associated with lenticular levee, crevasse-splay, or mouth-bar deposits of a semi-arid alluvial plain on which anastomosing channels dominated. The Okavango River of south-central Africa and Cooper's Creek in central Australia are proposed as modern analogues.The upper succession of Member B is characterized by sheet sandstones made up of top-truncated trough and planar cross-stratified units, with abundant plant litter and calcareous intraclasts. The rocks are interpreted as braided-fluvial sand sheet deposits that blanketed the lower succession floodplain. Petrographic and paleocurrent data suggest a common source for both successions. The progradation of the braided sand sheet may reflect a sedimentary response to climate change, tectonic rejuvenation, or a combination of both.

Do So

The progress of intracocoon development in relation to temperature and moisture is described for a one-generation and a two-generation area in eastern Canada. In the one-generation area (central Gaspé) the degree of seasonal emergence from the overwintered cocoons can be forecast with considerable accuracy by means of sample analyses during the period of pronymphal and early pupal development. This is possible since few individuals that have not initiated development by late June do so later in the summer, even though environmental conditions are quite favourable. The technique fails in a two-generation area (south central New Brunswick) because members of the overwintered population may continue to respond to favourable temperature and moisture conditions throughout the entire season.On the basis of biologic and climatic data the area occupied by the European spruce sawfly in eastern North America is divided into zones representing the probable distribution of one-, two-, and three-generation areas; intermediate transitional zones are also indicated.

Tectonic Style

The most northwesterly outcrop of Lower Cretaceous Chaswood Formation is in a pit at Vinegar Hill, south of Sussex, New Brunswick. New mapping and boreholes show thick, fluvial, loosely lithified conglomerates and lesser sandstones unconformably overlying 12 m of mudstone in a 1 km2 basin bounded to the northwest by the Clover Hill fault. Sparse paleocurrent indicators to the southwest parallel this fault. The tectonic setting is similar to that of the Chaswood Formation in the fault-bounded Elmsvale basin in Nova Scotia. In both cases, a basal unit is paraconformable on underlying upper Mississippian rocks, was folded into a syncline within which a middle unit accumulated and was further deformed, and is capped by thin flat-lying sandstone and conglomerate. The tectonic style of the Chaswood Formation at Vinegar Hill demonstrates that early Cretaceous deformation was widespread in the southern Maritimes. Gravel clasts consist overwhelmingly of vein quartz, but sparse lithic clasts match source rocks in south-central New Brunswick. Heavy minerals are mostly ilmenite (40%–70%) and staurolite (20%–40%), with monazite, zircon, and andalusite more abundant than at other Chaswood Formation localities. Heavy mineral chemistry and monazite geochronology suggest a provenance from Silurian metasedimentary rocks and tourmaline granites in central New Brunswick. Different mineral assemblages from the Chaswood Formation in Nova Scotia suggest that an ancestral St. John River drained western New Brunswick and supplied sediment to the Shelburne delta of the Scotian basin.
