Critical decisions: risk allocation in a model arthropod (Folsomia candida)
(2015-06-15)
Risk allocation theory predicts that foraging animals moderate predation risk by
allocating their foraging effort and space use according to their energetic demands.
Undernourished animals have a greater need for energy ...
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 ...
Developing a Multiplex PCR Platform to Determine the Virulence Genes of Escherichia Coli in Boulevard Lake, Thunder Bay, Ontario
Given the evidence that E. coli can establish in the periphytic community and be released back into the water column, it is important to understand the pathogenicity of this group of E. coli by examining the virulence genes ...
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 ...
Sources of small-scale variation in headwater stream habitat and macroinvertebrate communities
(2009-06-04)
The extent to which small stream habitats and communities are influenced by the
surrounding terrestrial environment is a function of the linkage between aquatic and
terrestrial systems. The strength of that linkage is ...
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 ...
