Abundance, transportation, and preservation of Mysis diluviana eDNA in freshwater ecosystems
(2021)Environmental DNA (eDNA) has proven to be a valuable tool in detecting rare or invasive species, particularly within the Great Lakes and surrounding aquatic ecosystems. Recent work has shown that sedimentary eDNA (sedDNA) ... -
Adaptive habitat selection by a single celled alga?
(2014-01-22)Faculty and students in the Department of Biology are bound together by a common interest in explaining the diversity of life, the fit between form and function, and the distribution and abundance of organisms. The research ... -
Addressing Indigenous community concerns of lake health by assessing water quality in Constance Lake, ON and biomarker responses in freshwater mussels, Pyganodon grandis and Lampsilis siliquoidea
(2023)Constance Lake First Nation has had concerns regarding the health of a culturally significant lake, Constance Lake, for several years. There are several external stressors to this lake including urbanization and forestry, ... -
Algal mixotrophic metabolism for the production of lipids
(2018)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 ... -
The antioxidant resveratrol down-regulates inflammation in an in vitro model of Pseudomonas aeruginosa infection of lung epithelial cells
(2014-01-22)Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen capable of infecting the lungs and causing severe pulmonary disease in immunocompromised individuals. During the infectious process, P. aeruginosa provokes ... -
Asian-American variant of human papillomavirus 16 E6 promotes the Warburg effect and hypoxia-inducible factor 1 signalling under hypoxia / by Sean Cuninghame.
Infection with high-risk human papillomavirus (HPV) is responsible for nearly all cases of cervical cancer, as well as a significant fraction of other ano-genital and head and neck cancers. Specifically, HPV type 16 (HPV ... -
Aspects of infectious agents and cancer : effects of human Papillomavirus 16 and Escherichia coli on the innate immune defense of human keratinocytes
(2012-11-10)Persistent human papillomavirus (HPV) is the causative agent of cervical cancer and bacterial vaginosis (BV) caused by Escherichia coli (E. coli ) has been implicated as a contributing factor. The innate immune system is ... -
Assessing in vitro DNA repair methods / by Ryan Lehto.
(2010)The DNA molecule is constantly under attack from endogenous and exogenous sources leading to degradation by a variety of forms of damage. In this study current methods of in vitro DNA repair methods were evaluated for ... -
Assessing the vulnerability of south-central Ontario’s maple syrup industry to climate change: a multidisciplinary approach
(2023)Productivity of Ontario’s maple syrup industry is tied to a specific climate window. As climate continues to change, there is growing concern over the industry’s vulnerability given its reliance on stable climate conditions ... -
The association between watershed characteristics and mercury concentrations in fish of Northern Ontario lakes
(2014-01-22)Many landscape, limnological, and ecological factors synergistically affect the mercury cycle and subsequently influence total mercury (THg) concentrations in fish. In Chapter 1, the associations between watershed and lake ... -
Bacterial isolation and bioconversion of organic materials to industrial platform chemicals
(2018)Careful selection/isolation of the suitable microbial consortium for enzymatic saccharification of organic matters is a critical step in biofuels production. We isolated strains EF2, OW1-1 and HK2 from intestine of Eisenia ... -
Bioenergetic evaluation of a whole-lake nanosilver addition on Yellow Perch (Perca flavescens)
(2018)Nanosilver (nAg) is an antibacterial and antimicrobial agent. Its wide use in hundreds of commercial products and industrial applications suggests a high potential for release into the environment. Previous research indicates ... -
