Testate amoebae (thecamoebian) based reconstruction of Lake Simcoe fringe wetland paleoenvironments
(2014-12-12)
Lake Simcoe, Ontario, Canada, a large southern Ontario
glacial lake, has been affected by multiple environmental
stressors throughout its history. This study uses testate
amoebae paleodistribution to reconstruct the ...
Detection of Deoxyribonucleic Acid Damage Induced by Metal Ion Interactions and Repair of Metal Ion Deoxyribonucleic Acid Cross-links
(2010-08-17)
There are many forms of DNA damage. One of these, DNA-metal cross-links are
particularly problematic as they not only affect the tautomeric structure of DNA, but can
also inhibit enzymatic activity and block amplification ...
The carcinogenic properties of naturally occurring human papillomavirus 16 E6 oncogene variants
(2013-02-03)
Human papillomavirus is the causative agent of the 2nd highest occurring cancer in women, cervical cancer, which is the result of expression of the E6 and E7 oncogenes. Here we challenged the dogma that the oncogenic protein ...
Lake trout and their egg predators' ability to locate spawning substrate using olfaction
(2014-01-22)
Lake trout spawning sites, and the substrate on these sites, are structurally unique
in many ways. These sites are generally at the end of the fetch of a lake, close to shore (1
m) and composed of small to medium sized ...
Functional niche differentiation in co-occurring congeneric plants
(2014)
Niche differentiation is argued as one of the mechanisms explaining species coexistence. Despite their sessile nature, similar resource needs and traits to acquire and utilize resources closely related plant species coexist. ...
Black Spruce (Picea mariana) Regeneration in Post-fire Cryptogamic Mats
(2016)
Post-fire black spruce (Picea mariana Mill.) regeneration has received
considerable attention in management of the boreal forest of eastern Canada. Seedbed
quality is a key factor for seed germination and early seedling ...
Chemoreception in invasive rusty crayfish (Orconectes rusticus): learning and adaptation in aquatic ecosystems of Northwestern Ontario
(2012-11-10)
Crayfish utilize chemosensory cues, in addition to other sensory inputs, to mediate a
variety of fundamental life processes. Exotic species, like the rusty crayfish (Orconectes
rusticus), are known to employ a broader ...
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 ...
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 ...
Role of safe sites in black spruce recruitment and growth release in post-fire Kalmia heath
(2014-01-22)
The goal of this thesis was to explain black spruce regeneration in postfire sheep laurel (Kalmia angustifolia L., hereafter referred to as Kalmia) dominated chronosequence in light of safe site density. The concept of ...
