Ice Association in Microbes
(2012-09-18)Microbes have a remarkable ability to adapt to a host of environmental stressors, including low temperature, high pressure and osmotic stresses. The adaptations of resistant microbes to low temperatures are varied, and ... -
Identification and Characterization of a Novel Antisense Non-Coding RNA from the T-DNA Locus of Rosewood, an Activation-Tagged Poplar Tree
(2015-07-29)Activation-tagging is a functional genomics technique where strong enhancers are inserted randomly into target genomes and can over-activate endogenous genes. When interesting phenotypes occur as a result, it can lead to ... -
Identification and characterization of GmCaMK1: a novel calmodulin-binding receptor-like kinase from nodules of soybean (Glycine max)
(2010-02-03)Ca2+ functions as a second messenger in all eukaryotes. Such Ca2+ signaling is used to coordinate plant responses to numerous stimuli, both developmental and environmental. Ca2+ signals are often transduced via the action ... -
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 ... -
Identification of compounds in heavy fuel oil 7102 that are chronically toxic to rainbow trout (Oncorhynchus mykiss) embryos
(2013-01-24)Spilled heavy fuel oil (HFO) sinks within the water column and accumulates in sediments, affecting aquatic organisms that are not typically exposed to oils that float. Previously, the 3-4 ring alkyl substituted polycyclic ... -
Identification of Genes Involved in the C. elegans VAB-1 Eph Receptor Tyrosine Kinase Signaling Pathway
(2011-07-29)The generation of a functional nervous system requires that neuronal cells and axons navigate precisely to their appropriate targets. The Eph Receptor Tyrosine Kinases (RTKs) and their ephrin ligands have emerged as one ... -
Identifying Genes That Regulate Secondary Growth In Poplar
(2008-09-24)Plant growth and development is largely controlled in regions of totipotential cells around the plant body called meristems. The well characterized shoot and root apical meristems are responsible for vertical growth, in ... -

Imaging Biologically-Based Clathrate Hydrate Inhibitors
(2010-04-13)The unscheduled formation of gas hydrate plugs in oil and gas pipelines, which can lead to serious mechanical and personnel damage, is a problematic issue in the petroleum industry. Traditionally, thermodynamic inhibitors ... -
The Impact of Migration on the Evolution and Conservation of an Endemic North American Passerine: Loggerhead Shrike (Lanius ludovicianus)
(2011-01-26)Migration acts as a selective force on the ecology and evolutionary trajectory of species, as well as presenting fundamental challenges for conservation. My thesis examines the impact of migration by exploring patterns ... -
Importance of Climate on Boreal Lakes from Northwest Ontario Over Millennia: A Paleolimnological Perspective
(2014-12-08)The lack of long-term data on the response of boreal lakes to climate change has been seen as an impediment to the assessment of the vulnerability and risks that northwest Ontario faces in light of future climate change. ... -
The Importance of Geospatial Inputs in Assessing Fine-scale Landscape Genetic Patterns of a Temperate Treefrog
Recent technological advancements in next generation sequencing techniques, enabling the use of thousands of genetic markers across an individual’s genome, and continued improvements to the spatial resolution and information ... -
The Importance of Live‐Well Transport in the Physiological Disturbance Experienced by Smallmouth Bass in Tournaments on Large Water Bodies
(Wiley, 2019)Competitive fishing has become an important element of recreational fisheries for black bass Micropterus spp. in North America. The vast majority of competitive events involve a “live‐release” format, where fish are held ... -
Improvement of a high throughput method for identification of T-DNA insertion events in an activation-tagged population of Populus tremula x Populus alba.
Mutant populations are a cornerstone of modern studies in genetics; their usefulness in gene discovery, and in understanding the various forms of gene regulation, can not be overstated. Since the introduction of mutation ... -
In vivo Interactions between PTP-3 RPTP and Various Signaling Pathways in the Caenorhabditis elegans Nervous System
(2014-09-23)The C. elegans nervous system offers a rewarding model in which many pathways can be studied with. There are many genes conserved in both invertebrates and vertebrates that are necessary for proper nervous system development. ... -
In Vivo Phosphorylation of Bacterial–Type Phosphoenolpyruvate Carboxylase From Developing Castor Oil Seeds at Threonine-4 and Serine-451
(2011-08-23)Phosphoenolpyruvate carboxylase (PEPC) is a tightly controlled anaplerotic enzyme situated at a pivotal branchpoint of plant C-metabolism. Plant genomes encode several closely related plant-type PEPC (PTPC) isozymes, and ... -
In vivo regulatory phosphorylation of bacterial-type phosphoenolpyruvate carboxylase from developing castor oil seeds
(2011-09-07)PEPC [PEP(phosphoenolpyruvate) carboxylase] is an essential and tightly controlled enzyme located at the core of plant C-metabolism. It fulfils a broad spectrum of non-photosynthetic functions, particularly the anaplerotic ...
