Zooplankton community dynamics in the Trent Seven Waterway along Lake Simcoe and Lake Couchiching
The Trent Severn Waterway (TSW) is a 386km channel that connects Lake Ontario to Georgian Bay. There is a lack of information on the water quality in the nearshore region of the TSW specifically in regards to the planktonic ...
Phytochemical analysis of boreal forest flora of Northwestern Ontario, Canada
The following research document has been written in the format of a thesis by publication. As such, there is an introductory and concluding chapter to provide addition information and context to the scope of the study, ...
Effect of periphytic Escherichia coli and lake water bacterial population on the biofilm establishment of a Shiga toxin producing Escherichia coli O157:H7 strain
Biofilm studies Escherichia coli (E. coli) have typically focused on 0157:H7 in defined, laboratory medium. While there is value in such studies, they offer little in the way of explaining the behaviour and interactions ...
Biofilm formation of environmental and enterohemorrhagic Escherichia coli / by Stefan Moreira.
Sample sites : Boulevard Lake & Chippewa Park, Thunder Bay ; Billy Lake, Dorion (Northwestern Ontario).
Protease production and in vitro growth of Sarracenia purpurea
Prey digestion in the insectivorous plant Sarracenia purpuero was investigated with consideration of three sources of proteolytic enzymes self-digestion by the prey, bacteria in the plant pitcher, and enzymes produced ...
Predicting mixing trends in mine-receiving waters using water quality modeling
Complete mixing of the water column of lakes is important to ensure that nutrients and dissolved oxygen are replenished and equalized throughout the lake. This ensures that organisms within the lake at all trophic levels ...
Factors influencing thermal variability and fish distribution in small boreal steams / by Lisa McKee.
The spatial variability of stream temperature is an important component of habitat within streams providing optimal temperatures for foraging and thermal refugia for sensitive species such as brook trout. Riparian shading ...
Extraction of phytochemicals betulin and betulinic acid from the chaga mushroom and their effect on MCF-7 Cells
Chaga mushroom (Inonotus obliquus) grows on birch trees found mainly in temperate regions like Canada, Northern United States and Siberia. It contains phytochemicals such as betulin and betulinic acid, which are a ...
A multiomic approach to paleogenetic investigation of ancient North American bison
Twelve ancient bison bone samples from north-central North America were examined using genetic and proteomic sequencing to determine relationships to other bison populations. Mitochondrial DNA sequences suggest a genetic ...
Algal mixotrophic metabolism for the production of lipids
The challenges associated with the use of conventional sources of crude oil increase the demand for alternative fuel sources. Biofuels offer the chance of replacing the depleting fossil fuels. However, the food versus ...
