Acidification and Climate Warming: Understanding the Impact of Multiple Anthropogenic Stressors on Adirondack (NY, USA) Lakes
(2014-05-05)Lakes in the Adirondack Park (NY, USA) are undergoing chemical recovery from acidification. There is now a pressing research need to define recovery targets for acid-impacted sites. Researchers attempting to designate such ... -
Activation Tagging as a Powerful Tool for Gene Discovery in Poplar
(2007-11)Our understanding of tree growth and development has increased substantially in the last few decades and is expected to increase much more as we fully exploit newly developed genomic tools. A major milestone in tree genomics ... -
Activation tagging in Solanum tuberosum: Innate immune activation affects potato tuber periderm development
(2012-10-13)Activation-tagging is a functional genomics technique where strong enhancers are inserted randomly into target genomes to over-activate endogenous genes. Phenotypes of interest can be selected for investigation of genetic ... -

Age and Growth of Black Bass in Eastern Lake Ontario and the Bay of Quinte as Sampled Through Competitive Angling Events
(2015-07-08)This three year study (2012-2014) investigated the age and growth parameters of two economically important recreational fish species, Smallmouth Bass (Micropterus dolomieu) and Largemouth Bass (Micropterus salmoides). Age ... -
Age-dependent Effect of Environmental Light on Spectral Sensitivity and Body Colouration of Nile tilapia Oreochromis Niloticus
(2012-12-06)Signal reception and production form the basis of animal communication, and are largely constrained by environmental biophysical factors such as environmental light. However, the role of environmental light in producing ... -
Allometric Scaling in Centrarchid Fish: Origins of Intra- and Inter-specific Variation in Oxidative and Glycolytic Enzyme Levels in Muscle
(2007-11-01)The influence of body size on metabolic rate, muscle enzyme activities, and the underlying patterns of mRNA for these enzymes were explored in an effort to explain the genetic basis of allometric variation in metabolic ... -
Analysis of Cisco (Coregonus artedi) Populations in Eastern Lake Ontario
The Cisco (Coregonus artedi) is a cold-water planktivorous fish species that has undergone significant declines within Lake Ontario as a result of over-exploitation and other anthropogenic impacts. The goal of this project ... -
Analysis of E3 ligases and identification of ubiquitination sites regulating turnover of the plant immune signaling kinase BIK1
Plants possess sophisticated mechanisms for responding to the threat of pathogens. Microbial patterns such as bacterial flagellin are perceived by receptor complexes located at the plant plasma membrane. This perception ... -
Analysis of Human Thyroid Cancer-1 and Annexin V as Pro-Survival cDNA Sequences in Saccharomyces Cerevisiae
Overexpressing a mouse Bax cDNA in yeast cells induces cell death. When heterologously expressed in yeast cells overexpression of a mouse cDNA encoding Bax, human Thyroid Cancer-1 (TC-1) or annexin V (ANXA5) suppresses ... -
Apoptosis and Aging in Drosophila
(2008-10-27)Several genes involved in the regulation of apoptosis can influence longevity. Although observations in several different systems imply that apoptosis and aging are closely linked, the relationship between the two remains ... -
Aquatic community response to Zequanox®: a mesocosm experiment
Zebra and quagga mussels (Dreissena spp.) are European freshwater molluscs that have invaded most major inland water systems across North America, resulting in billions of dollars in damages and losses to fisheries, ... -
The Arabidopsis Calmodulin-Like Protein, CML39, Regulates Early Seedling Development and Fruit Formation
Calcium (Ca2+) is one of the most ubiquitous and versatile second messengers in eukaryotes. In the Ca2+ signaling paradigm, cytosolic Ca2+ oscillations, evoked by environmental stimuli, are detected by Ca2+-binding proteins, ... -
Arabidopsis Mitogen-Activated Protein Kinase Kinase Kinase Family Members and Their Possible Role in Innate Immunity
From an early developmental stage, plants are exposed to both beneficial and pathogenic microbes. Upon pathogen detection, receptor complexes on the cell surface can detect conserved microbial molecules, such as bacterial ... -
The Arabidopsis Putative Calcium Sensor, CML39, is Required for Seedling Establishment Under Carbon Limitation
(2013-05-30)As sessile organisms, coordination of development and reproduction in a dynamic, and often stressful, environment presents a particular challenge for plants. Rapid processing of internal and external cues by complex signal ... -
Arboreal Calling Behaviour Across the Range of the Spring Peeper: Potential Consequences and Benefits
Understanding the trade-offs that affect potentially adaptive traits is fundamental to our understanding of evolutionary diversification and speciation. Heterogeneous landscapes may lead to spatial variation in such traits ... -
Arsenic biotransformations in terrestrial organisms: A study of the transport and transformation of arsenic in plants, fungi, fur and feathers, using conventional speciation analysis and X-ray absorption spectroscopy
(2007-07-05)Arsenic taken up by plants and fungi from contaminated soils can subsequently be introduced into food chains. Given the toxic properties of some arsenic compounds, this may be a cause for concern. Much remains to be learned ... -
As Above so Below? - Impacts of Water Limitation on Growth and Nutrient Accumulation of a Crop Plant and its Soil Microbes Across a Fertility Gradient
Strategies to increase crop yields and drought stress tolerance are urgently needed to meet future global food demands in a changing climate. Although the effects of fertilizer application and drought stress in agriculture ... -
Assesing biological recovery from acidification and metal contamination in urban lakes from Sudbury, Canada : a paleolimological approach
(2008-07-11)The acidification and metal contamination of freshwater resources are major environmental concerns in many areas, with Sudbury (Ontario, Canada) having been amongst the most severely impacted. Many scientific investigations ...
