Wilson; Gossage, Robert A.The characterisation of the solid-state crystal structure of the hydrochloric acid salt of anti-cancer agent Flavopiridol (i.e., (–)-2-(2-chlorophenyl)-5,7-dihydroxy-8-[(3S,4R)-3-hydroxy-1-methyl-4-piperidinyl]-4H-1-benzopyran-4-one) is described. The title compound forms meta-stable X-ray quality crystals by slow evaporation of solutions of the material in aqueous methanol. The crystalline unit cell contains two organic cations, two formal chloride counterions and two molecules of methanol, one of which is replaced in 20% occupancy by a water molecule. The crystal form is of space group P1 with cell parameters a = 7.2014(10) Å, b = 12.0094(9) Å, c = 12.6581(14) Å, α = 89.146(4)°, β = 89.788(6)° and γ = 82.180(4)°. The unit cell volume is 1084.4(2)Å3. The general structural features of individual (gas-phase) molecules of protonated Flavopiridol and the naturally occurring 2-methyl-[4H]-chromen-4-one analogue Rohitukine have been calculated by application of Density Functional Theory (dft) at the b3lyp/6-31g* level of sophistication. These results are compared to the reported solid-state data of these two biologically relevant flavanoids.Item Open Access Late Blooming of Plants from Northern Nova Scotia: Responses to a Mild Fall and Winter(Nova Scotian Institute of Science, 2011) Garbary, David J.; Ferrier, Jonathan; Taylor, Barry R.Over 1400 flowering records of 135 species were recorded from over 125 visits to more than 20 sites in Antigonish County, Nova Scotia from November 2005 to January 2006, when the growing season is normally over. The species identified were primarily herbaceous dicots; however, there were four species of woody plants (Cornus sericea, Spiraea latifolia, Symphoricarpos albus and Salix sp.) and one monocot (Allium schoenoprasum). The number of species flowering declined linearly as fall progressed, as did the amount of flowering for each species. Nevertheless, over 40 species were still in flower in early December, and over 20 species flowered in January. The final flowering date was 21 January, when ten species were found. This work builds on a previous study in 2001, when 93 species were recorded in flower during November-December. In addition to the 30% increase in recorded species in 2005, almost 50% of the species found in 2005 were not recorded in 2001. This study provides an expanded baseline against which changes in flowering phenology can be evaluated with respect tosubsequent regional climate change.Item Open Access Can We Stop the Atlantic Lobster Fishery Going the Way of Newfoundland's Atlantic Cod? A Perspective(Nova Scotian Institute of Science, 2011) Corkett, Christopher J.The cod and lobster fisheries of Atlantic Canada are managed in very different ways. Regulatory policy for Atlantic cod has traditionally been based on population or biomass measurements, something that has never been done for the management of Atlantic Canada’s lobster. While these traditional methods differ, an alternate logical or analytic approach to management is perhaps one way that sound and rational fisheries can be managed. The recommendations that follow derive from asking: can we learn analytic lessons from the collapse of Atlantic cod that might allow us to avoid a similar collapse in Atlantic lobster? A landings-per-unit-of-effort (LPUE) index could be constructed for the lobster industry that would provide a continuous trend over time. This trend would form an effective feedback model; a declining trend over time would indicate the goal of sustainability was in jeopardy, whereas a level or increasing trend over time would indicate that the industry was maintaining its sustainability. Crucially, an LPUE index should only be used as an argument a posterior involving feedback in the form of trends. This index should never be used as an argument a priori to estimate lobster abundance or lobster biomass.Item Open Access Lasiurine Bats in Nova Scotia(Nova Scotian Institute of Science, 2011) Lucas, Zoe; Hebda, AndrewThree lasiurine bat species, Lasionycteris noctivagans (Silver-haired Bat), Lasiurus cinereus (Hoary Bat), and Lasiurus borealis (Red Bat), have been recorded in inland, coastal, and offshore locations as of Nova Scotia. Although these records occurred over a century, 70% are from the mid-1990s or later, largely because of research in mainland Nova Scotia, and increased interest on Sable Island. The 65 records presented here include 11, 25, and 29 for Silver-haired, Hoary, and Red bats, respectively, of which 31 are previously unpublished. Seventy-seven percent of records are from August through November, the autumn migration period for lasiurine bats. These observations suggest that most autumn occurrences of these species in Nova Scotia are not extralimital, but are part of normal migratory patterns in the province.Item Open Access Errata for Volume 46.1 (Special Issue)(Nova Scotian Institute of Science, 2011)Item Open Access Editorial: Celebrating 150 years of the NSIS and Maritime Science—Reflecting on the Society’s Role, and Identifying Future Roles and Challenges(Nova Scotian Institute of Science, 2011) Wells, Peter G.; Richardson, David H.S.Item Open Access Front Matter(Nova Scotian Institute of Science, 2011)
