We present new records of larvae and adult fish from the family Callionymidae in the Colombian Pacific coast. Larvae and juvenile of Synchiropus atrilabiatus (Garman 1899), expands its distribution range within this coast (between Tumaco in the South to the border with Panama in the North), presenting low to medium abundances in September-October 2002, 2003, 2004, 2005 and February-March 2006, 2014. Larvae were always collected at stations 54 km away from the coast. Adults of S. atrilabiatus were collected as bycatch from the deep-sea shrimp fishing fleet between 67-700 m depth at Bahía Cupica in 1995 and Arusí in 2005.

New data on 22 species of bees of the family Megachilidae from the North Caucasus and the south of European Russia are reported. Six species are new to Russia: Hoplitis curvipes (Morawitz, 1871), Osmia cinerea Warncke, 1988, O. ligurica Morawitz, 1868, O. cyanoxantha Pérez, 1879, Protosmia glutinosa (Giraud, 1871), and Coelioxys mielbergi Morawitz, 1880. Hoplitis turcestanica (Dalla Torre, 1896), sp. resurr. is treated as a distinct species, not a junior synonym of H. caularis (Morawitz, 1875). Megachile albocristata Smith, 1853 and M. alborufa Friese, 1911 are listed instead of previously recorded M. lefebvrei (Lepeletier de Saint-Fargeau, 1841) and M. pyrenaica (Lepeletier de Saint-Fargeau, 1841), respectively. Fourteen new regional records are reported: seven species are new to the North Caucasus, five ones are new to the south of European Russia, and two species are new to the European part of Russia as a whole. The numbers of megachilid bee species currently known in Russia, the North Caucasus, and the south of European Russia are 217, 130, and 71, respectively. The lectotype of Osmia proxima Morawitz, 1875 is designated.

Abstract Walrus fossils are occasionally recovered during scallop dragging in the Bay of Fundy and from sand and gravel deposits along the coastline of New Brunswick in eastern Canada. Six new fossils and four new AMS radiocarbon dates significantly increase the information concerning late-glacial to postglacial walrus in New Brunswick. Dates range from about 12 800 BP to 2 900 BP, almost half falling between 9 000 and 10 000 BP. Temporal distribution of walrus, compared to estimates of past summer sea surface temperature, suggest that in the Bay of Fundy walrus occurred in waters ranging from 12 to 15° C.

The Nahanni and Liard mountain ranges are located at about 61° N latitude and 122° W longitude. They form the easternmost slopes of the Rocky Mountains and lie just east of Nahanni National Park in the southwestern corner of the District of Mackenzie, Northwest Territories. The moss flora of the area is rich in the number of taxa; 207 species and two varieties are reported from this relatively small area. Of these, 53 species are new records for the South Nahanni region. A number of rare or disjunct bryophyte species are found in the area. Moss species which are either disjunct or occur at the edge of their range include Arctoa fulvella (Dicks.) B.S.G., Aulacomnium acuminatum (Lindb. & Arn.) Kindb., Andreaeobryum macrosporum Steere & B. Murray, Geheebia gigantea (Funck) Boul., Isopterygiopsis muelleriana (Schimp.) Iwats., Mnium spinosum (Voit) Schwaegr., Psilopilum cavifolium (Wils.) Hagen, Rhabdoweisia crispata (With.) Lindb., Seligeria calcarea (Hedw.) B.S.G., S. polaris Berggr., Trematodon brevicollis Hornsch., and Trichostomum arcticum Kaal. The North American distribution of these species is mapped. Herbertus stramineus (Dum.) Trev., Metacalypogeia schusterana Hatt. & Mizut., Scapania crassiretis Bryhn, and S. simmonsii Bryhn & Kaal. are four hepatic species of phytogeographic interest.

Based on unedited bryophyte collections from the Arabian Peninsula and Socotra Island, six new records of mosses are reported for the area. New to the Arabian Peninsula are Pohlia elongata and Ptychostomum cernuum, the remaining four species are new records for Saudi Arabia, resp. Yemen (mainland) and the Socotra Archipelago. Most interesting is Hymenostylium hildebrandtii from the Makkah-Taif area, indicating the influence of the south-western monsoon rainfall far to the north. All taxa show major range extensions in Southwest Asia and contribute to the floristic diversity of the Arabian Peninsula.

Drill Cores

Bulk magnetic susceptibility (BMS) measurements have been made on granite drill cores from the St. George batholith (New Brunswick), the South Mountain batholith (Nova Scotia), and the Wedgeport pluton (Nova Scotia). The primary magnetite concentrations of the two Nova Scotia cores are statistically indistinguishable, thus lending support to the hypothesis that the Wedgeport pluton, despite being 50 Ma younger, is a satellite of the South Mountain batholith.The St. George core has a primary magnetite concentration over 30 times greater than the Nova Scotia cores, but low-temperature alteration (attributable to subsurface weathering) has greatly reduced its magnetite content. The two Nova Scotia S-type granites are shown to fall into the ilmenite-series category, whereas the St. George granite, which is either S- or A-type, is transitional between the magnetite and ilmenite series.The general observation of intergranular hematite and reduced BMS in the outcrops of some granites is suggested to have important consequences for primary oxidation studies and aeromagnetic interpretation.

St Lawrence Estuary

The Goldthwait Sea is defined as the late- and post-Glacial marine invasion in the St. Lawrence Estuary and Gulf east of Québec City. In Québec, this sea has submerged an area of about 25 000 km2. The largest areas submerged are the north shore of the St. Lawrence between Les Escoumins and Blanc-Sablon, the south shore between Levis and Tourelles, and the Anticosti Island. The upper limit of the Goldthwait Sea varies from place to place. The Goldthwait Sea began 14 000 years ago and land emergence is still in progress, since the pre-Wisconsin marine level has not been recovered yet. For a better chronology, this long interval needs to be subdivided. Three main periods have been recognized: Goldthwaitian I, II and III. However, a geographical subdivision is also needed. Numerous shorelines were observed at various elevations throughout the area formely submerged by the Goldthwait Sea. However, only a few shorelines are well developed and extensive, and correlations between former shorelines are difficult to establish. Only three levels are widespead and common to the Estuary and parts of the Gulf. The isostatic recovery has been rapid during the first three thousand years after déglaciation of the area: about 75%.

Boreohydra simplex was collected at a depth of 400 m in Cabot Strait, eastern Canada; this solitary, mud-dwelling hydroid is previously unreported from the western North Atlantic. Elsewhere, it has been found along the coasts of Scandinavia, Britain, and Iceland in the North Atlantic, and from South Georgia in the South Atlantic.

Chitinozoan studies recently carried out in the “Appalachian Forelands and St. Lawrence Platform” National Geoscience Mapping Program (NATMAP) project have confirmed the regional biostratigraphic value of a number of chitinozoan species and led to a better documentation of their stratigraphic and geographic distribution in eastern Canada. The typical Darriwilian microfaunas first described from the Table Head Group of western Newfoundland and containing Conochitina chydaea are now recognised in the Rivière Ouelle Formation at Les Méchins, Gaspé Peninsula. In the Upper Ordovician successions of the St. Lawrence Platform at Neuville and in the Charlevoix area, Quebec, Conochitina primitiva is indicative of the multidens–pre-americanus graptolite zonal range, Hercochitina duplicitas of the americanus Zone, and Hercochitina spinetum and Acanthochitina cancellata characterize the ruedemanni – lower spiniferus zonal interval. The occurrence of Cyathochitina vaurealensis and Hercochitina crickmayi in turbidite deposits of the Grog Brook Group of northwestern New Brunswick confirms the minimal facies dependence of these two Richmondian index species. Eisenackitina dolioliformis, characteristic of the late Aeronian and Telychian successions of Arctic Canada, Gaspé Peninsula, and Anticosti Island, is now recognised in samples from the Upsalquitch Formation of northwestern New Brunswick and the Cabano Formation of the Rimouski area in Quebec. The palynological data from Devonian successions of the Matapedia Valley, the Rimouski area, and the Beauce – Eastern Townships region show that the succession of Lower Devonian chitinozoan assemblages of the Forillon Peninsula based on short-ranging species can be used in establishing regional correlations in the Gaspé Belt.
