Two New Species

The Hanford Brook Formation, one of the classic Cambrian units of Avalonian North America, contains at least eight species of endemic trilobites, including Berabichia milleri Westrop n. sp., that are assigned to seven genera. The vertical succession of faunas is far more complex than has been recognized previously, with each member containing a lithofacies-specific assemblage. These are, in ascending order: a bradoriid-linguloid Association without trilobites in the nearshore St. Martin's Member, a Protolenus Association in dysaerobic siltstones and sandstones of the Somerset Street Member, and a Kingaspidoides-Berabichia Association in hummocky cross-stratified sandstones of the Long Island Member that overlie a parasequence boundary at Hanford Brook. Due to the breakdown of biogeographic barriers in the late Early Cambrian, two new species-based zones, the Protolenus elegans and Kingaspidoides cf. obliquoculatus zones, share trilobite genera with the Tissafinian Stage of Morocco. This generic similarity has been the basis for correlation of this upper Lower Cambrian interval on the Avalon continent with the West Gondwanan lowest Middle Cambrian. However, the clear facies control on the occurrence of genera in the Hanford Brook Formation and the presence of an abrupt faunal break and unconformity at the base of the Tissafinian in Morocco makes this correlation questionable. The Hanford Brook Formation may represent a late Early Cambrian interval unknown in Gondwana. Sequence-stratigraphic criteria even raise the possibility that the Protolenus Association is the biofacies equivalent of Callavia broeggeri Zone faunas of the Brigus Formation of Newfoundland, Nova Scotia and Massachusetts.

In Nova Scotia the threatened Northern Ribbonsnake, Thamnophis sauritus septentrionalis, (the northern subspecies of the Eastern Ribbonsnake, T. sauritus) (Crother 2008) is known from localities in only Queens and Lunenburg counties, where it was first discovered in 1950. Many new localities, mostly in the headwaters of the Mersey River and the Medway River watersheds have been added since 2002, and Seven Mile Lake (in the West La Have River watershed) was added to the distribution in 2005. We add two localities to the distribution of the Northern Ribbonsnake in the previously unreported Petite Rivière watershed, Lunenburg County, Nova Scotia.

Seasonal relationships between size, bottom temperature, and distribution of cod are described for the western Gulf of St. Lawrence and Nova Scotia Banks.In summer, in the western Gulf of St. Lawrence, cod are distributed from 35 to 145 m at bottom temperatures from −0° to 6 °C. They are most abundant at about 100 m where the temperature is around 1 °C. In winter they are concentrated in 130–180 m along the western slope of the Laurentian Channel at bottom temperatures from 1° to 3 °C.On the Nova Scotia Banks cod are less abundant than in the Gulf of St. Lawrence. They are found mainly around Banquereau, Middle Ground, and the northern edges of Sable Island Bank. Further to the west cod are replaced by haddock as the dominant species. Nova Scotia Banks cod are found in shallower and warmer waters than Gulf cod, both in summer and winter. In summer they are present from 65 to 110 m at bottom temperatures varying from about 1° to 8 °C. In winter they are taken primarily at 90–135 m at bottom temperatures from 2° to 4 °C.Area and depth distributions of commercial catches reflect the seasonal pattern of cod migrations and distributions demonstrated in surveys and tagging studies.

Abstract British travellers commented frequently on those of African descent they encountered in colonial Nova Scotia, especially their material conditions and prospects. Those who published accounts at the peak of the campaign to abolish slavery in the British Empire intervened directly in debates about whether former slaves would prosper under conditions of colonial freedom. They cast themselves as objective imperial observers and Nova Scotia’s black communities as experiments in free labour. Attending to how most crafted and reworked their observations to argue against emancipation in the West Indies situates Nova Scotia and travel texts in intellectual histories of the production of colonial knowledge, debates about slavery, and the nature of nineteenth-century liberalism.

Postorogenic alkali feldspar granite and associated pegmatites in West Avalonia: the petrology of the Neoproterozoic Georgeville Pluton, Antigonish Highlands, Nova Scotia

The 579.8 ± 2.2 Ma (40Ar-39Ar, muscovite) Georgeville Pluton in mainland Nova Scotia is an epizonal body consisting of alkali feldspar granite and related pegmatite. The pluton intrudes the ca. 619-608 Ma arc-related rocks of the Georgeville Group, which comprises part of West Avalonia, the largest terrane in the Canadian Appalachians. The granite is characterized by above-average SiO2, Th, Nb, Y, and Zr; very low CaO, TiO2, MgO, FeO, and MnO; and most notably by positively sloped rare earth element (REE) profiles generated by extreme light REE depletion. Tectonic discrimination diagrams suggest a within-plate environment, with many, but not all, geochemical and mineralogical features resembling A-type granites. Numerous local and regional geological constraints indicate that the pluton was intruded in a trancurrent setting following the cessation of Neoproterozoic arc-related magmatism along the West Avalonian portion of the Gondwanan continental margin. Geochemical data are consistent with derivation by partial melting of depleted crust or upper mantle followed by extreme fractionation, including REE-rich accessory phases.

The West Indian Road pit is the only large outcrop in Nova Scotia of the Chaswood Formation, the terrestrial equivalent of the offshore Missisauga and Logan Canyon formations. It provides outcrop information on sedimentology, gravel petrology, and structures for a formation that is otherwise known from a few small overgrown pits and from boreholes. The Chaswood Formation in the pit is > 60 m thick and consists principally of sorted sand and gravel with three thinner clay units. Successions of sedimentary structures indicate deposition from a coarse-bedload river flowing to the east-southeast. Gravel consists principally of vein quartz, quartz arenite, and subarkose, together with minor igneous lithologies that can be matched to sources in the Cobequid Highlands to the north. Quartz arenite and subarkose appear derived from Carboniferous Horton Group. Single-crystal 40Ar/39Ar dates of detrital muscovite are a little older than the muscovite ages for the South Mountain batholith, interpreted to mean that the muscovite is second cycle from the Horton Group, which records the earliest unroofing of the batholith. The Chaswood Formation accumulated during progressive tectonic deformation along NNE-trending strike-slip faults in basement rocks, resulting in syn-sedimentary faulting and local unconformities. Sedimentation kept pace with the creation of accommodation. Unrelated younger deformation folded the Chaswood Formation at the pit into an east–west-trending syncline. The Early Cretaceous paleogeography of the Maritime Provinces is interpreted to have consisted of fault-bound horsts shedding coarse detritus surrounded by an interconnected series of basins that accumulated fluvial sands and gravels and overbank muds with well-developed paleosols.

This chapter sets the context for the Maroon relocations to Nova Scotia and Sierra Leone. It describes the reconfiguration of the British Empire in the aftermath of the American Revolution, and the importance the British placed on colonizing under-populated zones with loyal subjects. It explores the importance of laborers and settlers—voluntary and involuntary, white and black—for the security of faraway settlements. Second, it examines how the growing abolition movement in England affected the West Indies and shaped utopian visions for Sierra Leone. Last, it explores how the Maroons survived slavery, and benefited from abolitionism and an expanding British Empire. Three successive ex-slave migrations – of the London poor in 1787, of the Nova Scotian loyalists in 1792, and of the Jamaican Maroons in 1800 –established British claims in West Africa. This work describes the circuitous route taken by the last group of free blacks who entered West Africa before the end of the slave trade in 1807.

Wireworms are considered among Europe's most destructive insects, particularly Agriotes lineatus (L.), Agriotes obscurus (L.), and Agriotes sputator (L.). These species have been introduced at certain isolated localities on the East Coast and the first two on the West Coast of Canada. They are known to be particularly widespread in Nova Scotia where they and native Agriotes mancus (Sav) cause cansiderable crop damage.
