The Calmodulin-Like Protein CML42 is Involved in Trichome Branching in Arabidopsis
(2009-09-16)The Snedden lab has been studying a family of Ca2+-binding proteins from Arabidopsis that are related to the prototypical Ca2+ sensor calmodulin (CaM) and are termed CMLs (CaM-like proteins). Previous work on CML42 ... -
Can genomic tools aid conservation of an arctic seabird, the northern fulmar (Fulmarus glacialis)?
Human activities and climate change threaten Arctic ecosystems. Population genetics and genomics may help conservationists appropriately manage threatened species both by (1) determining the population genetic structure ... -
Carry-over effects in American redstarts: Implications for sexual selection and behaviour
(2008-09-23)Migratory birds spend most of the year on the over-wintering grounds or traveling between breeding and wintering areas, but research has focused on the relatively short breeding period. As a consequence, we have only a ... -
Cellular Mechanisms Involved in Stress-Induced Coma and CNS Spreading Depression in the Locust
(2010-08-06)Spreading depression (SD) is an interesting and important phenomenon due to its role in mammalian pathologies such as migraine, seizures, and stroke. Until recently investigations of the mechanisms involved in SD have ... -
Cellular signalling pathways involved in thermoprotection of neural ciruit function in the locust.
(2009-08-27)Environmental temperature is arguably one of the most important abiotic physical factors affecting insect behaviour. Temperature affects virtually all physiological processes including those that regulate nervous system ... -
Changes in Diatom Assemblages in Adirondack (NY, USA) Reference Lakes Since Pre-Industrial Times
(2014-05-30)The vast majority of Adirondack lakes have been impacted since pre-industrial time through either regional (e.g. acidification) or local (e.g. fish stocking, liming, seepage of road salt, cultural eutrophication) environmental ... -
Changes in Patterns of Territory and Habitat Overlap in Wood-Warblers Over Evolutionary Time
(2012-01-09)Patterns of community assembly among organisms are highly influenced by the ecological traits and strategies of the species that make up those communities. The conservation of ancestral traits can be important in determining ... -
Changes in Scaled-Chrsyophyte Assemblages in Response to Recent Climate Change in Northwestern Ontario
(2011-09-30)A two-part paleolimnological study was conducted to: i) understand the important factors that are related to the present-day distribution of scaled-chrysophytes; ii) investigate changes in the scaled-chrysophyte assemblages ... -
Changes in the Ecology and Abundance of Smallmouth Bass in Lake Ontario: 1958-2014
(2016-10-04)Understanding the reasons for long-term population change in a species requires an evaluation of ecological variables that may account for the observed dynamics. In this study, long-term changes in indices of Smallmouth ... -
Characterization and Knockdown of a Family of Ice-Binding Proteins from Freeze-Tolerant Grasses
Exposure to sub-zero temperatures puts plants at risk of freeze-induced damage associated with ice crystal formation causing cellular dehydration, plasma membrane rupture and cell death. Some freeze-tolerant plants induce ... -
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 ... -
Characterization of Farnesoic Acid O-Methyltransferase (FAMeT) and Juvenile Hormone Acid Methyltransferase (JHAMT) in relation to Drosophila melanogaster Juvenile Hormone Biosynthesis
(2007-10-04)Juvenile hormones (JHs) are key regulators of both metamorphosis and adult reproductive processes. The role of two key enzymes in the biosynthetic pathway of JH were examined: Farnesoic Acid O-Methyltransferase (FAMeT) ... -
Characterization of insulin signaling in a Caenorhabditis elegans Alzheimer’s disease model
Insulin is a key hormone in the regulation of blood glucose levels in many animals. Dysfunctional insulin signaling is one of the leading mechanisms of interest for the pathogenesis of diabetes and Alzheimer’s disease (AD). ... -
The Characterization of Metal Biotransformation Capabilities of Photosynthetic Microorganisms
(2015-07-29)Industrial activity over the last two centuries have increased heavy metal contamination worldwide and has led to greater human interaction with these contaminants. Cadmium, copper and zinc are particularly common industrial ... -
Characterization of Rockmass Properties and Excavation Damage Zone (EDZ) Using A Synthetic Rock Mass (SRM) Approach
A detailed understanding of strength and fracturing behaviour of the rockmass is essential for coherent design of underground structures such as deep geological repositories (DGRs) for long-term nuclear waste storage. The ... -
Characterization of Signal Transduction Pathways Required for Starvation Longevity in the Model Nematode Caenorhabditis Elegans
Growth and development is controlled by specific sets of gene products (proteins and RNAs), forming metabolic and developmental pathways. Mutations in these genes can result in abnormal growth of cells, leading to diseases ... -
Characterization of the C. elegans PLM Mechanosensory Neurons at the L1 larval stage
(2012-10-29)Axon guidance is the developmental process where developing neurons navigate their processes based on attractive and repulsive cues. C. elegans has been an instrumental model in the study of neurobiology with one of the ... -
Characterization of the fhod-2 gene in Caenorhabditis elegans
(2011-06-20)Formins are a family of proteins responsible for a vast array of cellular functions such as cell shape, adhesion, cytokinesis and morphogenesis. Formin regulation of actin is a highly regulated process and is conserved ... -
Characterization of the locust retinoid X receptors
(2007-12-20)The retinoid X receptor (RXR) participates in a multitude of nuclear receptor signaling pathways and is induced by its highly sought-after cognate ligand, 9-cis-retinoic acid (9-cis-RA). In flies and moths, molting is ... -
