Ensuring that women have timely access to safe, effective and affordable emergency contraception (EC) is of critical importance. There are four primary modalities of EC available in Canada: the levonorgestrel emergency contraceptive pill (LNg-ECP), the copper-T intrauterine device (IUD), ulipristal acetate (UPA) and the Yupze method (combined oral contraceptive pills). This is a mixed methods study dedicated to exploring women’s knowledge of, access to and experiences with EC in New Brunswick (NB). This study consisted of a two-part mystery client study, a community-based survey, and in-depth, semi-structured interviews with women in NB. The results of the mystery-client study indicate that 180 (87%) pharmacies had at least one brand of LNG-ECPs in stock. Although availability and knowledge of LNG-ECPs among NB pharmacists is relatively high, some are still providing incorrect medical and regulatory information. The findings of this study illustrate where improvement in pharmacy provision of LNG-ECPs in NB is required. Knowledge of EC among women in NB is relatively low, especially with respect to the IUD and UPA. Continuation of education efforts among pharmacists and sexual education teachers concerning ECPs in NB appears warranted. Exploring the barriers that NB women face in obtaining ECPs is not only imperative for improving access, but also yielding better quality reproductive health services in the province.

In the summers 1997, 1998 and 1999, over 100 aquatic invertebrate kick samples were collected in the Northwest Miramichi River of northeastern New Brunswick to examine the effects of chronic heavy metal exposure on the aquatic predatory Plecoptera community. In the group of predators, Neoperla (Plecoptera) was numerically dominant and gut content identifications were used to determine food chain and life cycle stages. Neoperla diet analysis indicated the Chironomidae (Diptera) as the dominant prey with predation upon Trichoptera and Ephemeroptera influenced by the life cycle stage of the predator. Gut content totals were analysed for predatory diet changes due to heavy metal contamination exposure. The Neoperla community indicated a prey shift from a Chironomidae based diet to one including a higher percentage of Ephemeroptera and Trichoptera earlier in the predators life history when compared with upstream control sites. Neoperla diets maintained their shift from the control station diets as the downstream movement of heavy metal contaminated water mixed and dissipated within the study area.

A three-year (1998-2000) field and laboratory study conducted in Fredericton, New Brunswick, Canada analyzed and quantified the dispersal of adult Colorado potato beetles within and between conventional and transgenic potato plots established according to the high-dose/refuge strategy. More specifically, the study addressed the following four predictions: (1) Adult Colorado potato beetle abundance or flight activity in transgenic potato fields is positively correlated to the abundance or flight activity in the immediately adjacent refuge field. (2) Colorado potato beetle intraspecific competition on potato plants will increase the flight take-off frequency of adult CPB; tolerating relatively high numbers of CPB egg masses or larvae or a high level of CPB defoliation on potato plants in the refuge could therefore be considered to increase the movement of beetles from the refuge to the transgenic field. (3) CPB flight take-off frequency will be higher on potato plants at the bloom than at the vegetative stage; planting of the non transgenic potato crop in the refuge earlier than the Bt transgenic potato crop in the main field could therefore be considered to increase movement of the Colorado potato beetles from the refuge to the transgenic field. (4) The aggregated distribution of CPB populations in the potato crop is caused by the presence of mating pairs; strategies changing the distribution of males and females in the refuge field could therefore be considered to increase dispersal from the refuge to the main crop field. / Population monitoring using plant counts, flight interception traps, flight landing traps and pitfall traps established that a transient population of adult CPB is present in the transgenic potato fields throughout the crop season and that the abundance of the beetle is higher than that required by the high dose/refuge strategy models. Furthermore results showed that the beetles invading the transgenic field population originate as much from the surrounding fields of conventional cultivars as from the adjacent refuges. It would therefore be possible to relax existing requirements for the refuge to be located immediately adjacent to the transgenic crop. / Like most insects, the adult CPB populations are aggregated and can be fitted to a negative binomial distribution over the crop season. This study revealed that the distribution results from the presence of mating pairs for the overwintered population and from the clumped pupation for the non breeding summer population. The activity of the males in search of females is at least partly responsible for the higher dispersal activity observed with the overwintered than with the summer populations. The comparatively low level of dispersal activity with the summer population could affect the efficacy of the high/dose refuge strategy during the later part of the crop season. / Results of flight chamber tests demonstrated that plant phenology and intraspecific competition have a positive effect on flight take-off frequency. These findings suggest that summer adult dispersal between the refuges and the transgenic crops could be stimulated by manipulating planting dates and the abundance of the different CPB life stages on the plants. / Together, the results of the thesis provide support for some of the premises of the high dose/refuge strategy and offer new information on the CPB dispersal that could be used to further improve its efficacy. Although the transgenic potato (NewLeaf) is not commercially available at this time, the threat of CPB resistance to new products or resistant cultivars under development makes it important to continue the research required by CPB resistance management plans.

The Mabou Group in the Picadilly region of New Brunswick consists predominantly of red siltstones with interbeds of sandstone and conglomerate. The Mabou is of importance in this region as it overlies evaporite deposits of economic value. Given that the Mabou is several hundred meters thick, yet possesses no significant marker beds, it has remained stratigraphically undifferentiated in the Picadilly region over the course of previous regional mapping efforts in the area. Given the lack of a stratigraphic framework, coupled with insufficient hydrogeological sampling and test data to delineate any laterally extensive flow zones, the hydro-stratigraphy of this sedimentary package has not been established. Based on experience gained at other operations, Potash Corporation of Saskatchewan Inc. (PCS) recognized the need to take a proactive approach towards understanding the hydrogeology of the Picadilly mine development site. PCS has used a specialized technique in characterizing boreholes to measure depth-profiles of hydrophysical properties by logging the electrical conductivity of the borehole fluids over a period of time. Through the interpretation of these logging results, with the context provided by conventional geophysical logging data and nearby exploration drill core, this research seeks to identify zones of flow and assess whether or not any major units with lateral connectivity can be identified. The results highlight four zones of interest within the Mabou: the Upper Mabou; vuggy porosity directly above gypsum-infilled fractures; vugs and fractures within the Medium Sandstone subdivision; and the lower Mabou Siltstone at the base of the Mabou Group (within ~15m of base). Three of these zones are of interest as they tend to have relatively high permeabilities, with permeabilities over 10 000 md measured within the Upper Mabou, as high as 1800 md in the vuggy porosity zone directly above gypsum-filled fractures and as high as 1900 md within the Medium Sandstone subdivision . The fourth zone, found at the base of the Mabou Group, is of interest because the modest to low permeability recorded (as high as 38 md) is higher than the surrounding rocks and is in close proximity to the caprock of future mining activity. The permeabilities of the rocks studied in this research are believed to be dominantly controlled by secondary porosity. In the case of the permeable zone identified above the zone of gypsum-infilled fractures, relatively high porosities (9 to 15%) were interpreted from geophysical logs. These elevated porosities are due to the presence of vuggy porosity in this zone. However, no clear correlation between log-derived porosity and permeability was observed for the other permeable zones. This is believed to be due to the fact that fractures were the dominant control on porosity in these zones, and that the incremental contribution of fracture porosity to total porosity was too small to be readily identified.
