Diatoms as Indicators of Environmental and Climatic Change in Peatlands and Lakes Located Across the Boreal Shield and Hudson Bay Lowlands of Canada
Long-term monitoring data and paleoecological records are lacking in the Far North of Ontario (~50- 57oN, 79-94oW), a region of ecological and economic significance to Canada. As a landscape covered by extensive peatland ...
In vivo regulatory phosphorylation of bacterial-type phosphoenolpyruvate carboxylase from developing castor oil seeds
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 ...
Correlates and temporal variation in call phenology of eastern Ontario frogs
Climate change has been predicted to have long-term consequences for North American ecosystems. Amphibians in particular are considered indicators of ecosystem health because of their sensitivity to environmental change – ...
Characterization of the C. elegans PLM Mechanosensory Neurons at the L1 larval stage
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 ...
Age-dependent Effect of Environmental Light on Spectral Sensitivity and Body Colouration of Nile tilapia Oreochromis Niloticus
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 ...
Windows of opportunity: the timing of dispersal events influences zooplankton community response to environmental change in Subarctic ponds
Theoretical and empirical work has shown that community diversity and composition can be influenced by both local conditions and dispersal from a regional species pool. This may be especially true shortly after environmental ...
Summer precipitation limits plant species richness but not overall productivity in a temperate mesic old field meadow
(Journal of Vegetation, 2019)
Importance of Climate on Boreal Lakes from Northwest Ontario Over Millennia: A Paleolimnological Perspective
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. ...
Timing and Mechanism of Sepsis-Induced Delayed Gastric Emptying in a Novel Mouse Model
Sepsis-induced delayed gastric emptying is a significant clinical problem for patients in intensive care units worldwide. A series of studies were carried out to examine the nature and mechanisms of sepsis-induced delayed ...
