A Paleolimnological Examination of Cladoceran (Branchiopoda, Crustacea) Assemblages in Softwater Nova Scotia (Canada) Lakes and Their Responses to Multiple Stressors
(2012-08-22)
The Canadian province of Nova Scotia has an abundance of lakes impacted by multiple stressors, including acidification, lakewater calcium (Ca) decline, climate change, and fish introductions. In spite of this, little is ...
Biochemical Responses of Arctic Soil Communities to Anthropogenic Stress
(2013-06-04)
We are living in the era of climate change which becomes more complicated whenever some new environmental issue emerges only to get linked with this already existing challenge. Engineered nanoparticle (NP) contamination ...
Characterization of DAF-18/PTEN’s Role in Survival and Cellular Proliferation During Larval Arrest in Caenorhabditis elegans
(2014-04-02)
The role of insulin/IGF signaling (IIS) in regulating longevity and dauer formation in C. elegans is well defined. However, the role of IIS in stress responses such as L1 arrest is less studied and poorly understood. One ...
The Genetic Architecture of Life History in Drosophila
(2014-05-07)
An organism’s entire life history - the timing of development, reproduction, senescence and death - can depend on the nature of selection for reproductive age. The outcome of selection will depend both on the particular ...
No Evidence of Sampling Bias in a Comparison of Two Common Avian Capture Methods
(2015-08-20)
A common assumption underlying many biological studies is that the data we collect from a subset of individuals are representative of the broad population of interest. However, in studies of free-ranging animals, different ...
Characterization of the Potential Use of Salix Nigra and Populus Balsamifera for the Phytoremediation of 1,4-Dioxane
(2015-01-26)
Phytoremediation is a viable technology that provides a cost-effective and aesthetically pleasing alternative to traditional remediation technologies. The objective of this study was to compare the effectiveness of Salix ...
Experimenting with sex and speciation: Does intersexual co-evolution drive population divergence?
(2008-09-12)
It has been almost 150 years since Darwin’s “The Origin of Species” was published, yet the mechanisms that lead to the creation of new species are still a topic of fervent research in Evolutionary Biology. In the last ...
Identification of components in crude oil that are chronically toxic to the early life stages of fish
(2008-01-02)
The risk of crude oil exposure to the early life stages (ELS) of fish is difficult to assess, given the complexity of the chemical composition of different oils. The aromatic portion of crude oil contains polycyclic aromatic ...
Physiological and Behavioural Responses of Largemouth Bass Yearlings (Micropterus salmoides) to Hypoxia at Summer and Winter Temperatures
(2008-10-21)
The main objective of this thesis was to determine the metabolic and behavioural outcomes from hypoxia exposure to largemouth bass (Micropterus salmoides) yearlings when acclimated to either winter (5°C) or summer (20°C) ...
Molecular Identification and Messenger RNA Levels of a Monocarboxylate Transporter (MCT) in Fundulus Heteroclitus, a Hypoxia Tolerant Teleost Fish
(2009-09-03)
Monocarboxylate transporters (MCTs) are bi-directional symporters that couple proton movement to a variety of glycolytic metabolites, including lactate and pyruvate. As such, MCTs not only play a crucial role in pH ...
