Species richness, species incidence and turnover of amphibians in Northwestern Ontario : assessing the role of habitat characteristics
(2004)
There has been recent global concern over the decline of some amphibian
populations. The loss of amphibian species is of concern because they play a crucial role in
ecosystem structure and are indicators of ecosystem ...
Germination in pea seeds : proteolytic enzyme activity and electron microscopy
(1989)
This study was undertaken with two primary objectives in mind. The first objective was to isolate several pea seed hydrolases present during early seed germination. The second objective was to perform an ultrastructural ...
The effect of metformin on absolute telomere length
(2018)
In this study, the relationship between average absolute telomere length and metformin use was examined. Human blood samples were obtained from 106 participants ranging from 42-100 years old. Samples were split into four ...
Habitat change and the scale of predation risk
(2004)
In their efforts to maximise fitness while reducing the probability of dying, animals must trade off food for safety. The trade-off is likely to depend on habitat and habitat change. I imagine an environment with both safe ...
Nature and structure of DNA through the process of degradation
(2004)
The identification and characterisation of DNA damage is of great importance to
molecular research and has significant implications for clinical and forensic fields. From the
moment of cell death, DNA incurs many forms ...
Detection of Campylobacter jejuni in poultry samples using Florescent in situ Hybridization (FISH)
(2004)
In this study, a protocol using Fluorescent in situ Hybridization (FISH) for the detection of Campylobacter spp., particularly C. jejuni, in naturally contaminated poultry samples was developed and its application evaluated. ...
Effect of carbon-starvation on the survival of and PNP degradation by a Moraxella strain
(2004)
The effect of carbon-starvation on the stress resistance responses of a p-nitrophenol
degrading Moraxella strain was examined in both, buffer and river water
samples. The Moraxella strain showed optimal stress resistance ...
Limnology and remediation of two proximal pit lakes in Northwestern Ontario
(2005)
Two adjacent pit lakes, Caland and Hogarth, were formed after the closure and
subsequent flooding of the Steep Rock Iron Mines near Atikokan, Ontario, Canada. They
were examined to predict flooding patterns, outflow ...
Characterization of Campylobacter jejuni growing in biofilms under different conditions
(2005)
The viability of C. jejuni biofilms growing in different conditions was
investigated by conventional plate counts and microscopy after nucleic acid staining.
Differences were detected for each condition tested. However, ...
Mitochondrial DNA analysis of ancient hair shafts from the Dakhleh Oasis, Egypt : challenges and recommendations
(2005)
To date, there have been no previous reports in the literature on DNA extraction or
analysis of ancient human hair. The hair shaft has an extraordinarily stable structure that
enables it to remain unchanged for centuries ...
