Potential for anthropogenic disturbances to influence evolutionary change in the life history of a threatened salmonid
(2008-05)Although evolutionary change within most species is thought to occur slowly, recent studies have identified cases where evolutionary change has apparently occurred over a few generations. Anthropogenically altered ... -
A Potential Tool to Support the Prioritization of Blue Carbon Ecosystems in Canada
(2021-12)Globally, climate change and various anthropogenic activities have contributed to a significant decline in blue carbon ecosystems over the past few decades. These ecosystems can be prolific at accumulating and sequestering ... -
Poverty Among Senior Citizens - A Canadian Success Story

Poverty Impacts of Trade, Macro-Economic and Social Policy - Canada and the United States in the 1990's

The Poverty of mathematical and existential truth: examples from fisheries science
(2011-06-27)Several years ago I suggested that the harvesting of our commercial fisheries could be improved if the non-falsifiable models of a fisheries science were to be replaced with the falsiable models of a fisheries economics. ... -

Predicting and verifying the intended and unintended consequences of large-scale ocean iron fertilization
(2008)Ocean iron fertilization (OIF) is being considered as a strategy for mitigating rising atmospheric CO2 concentrations. One model for implementation is the sale of carbon offsets. Modeling studies predict that OIF has the ... -
Predicting mesoscale variability of the North Atlantic using a physically motivated scheme for assimilating altimeter and Argo observations
(American Meteorological Society, 2009-07)A computationally efficient scheme is described for assimilating sea level measured by altimeters and vertical profiles of temperature and salinity measured by Argo floats. The scheme is based on a transformation of ... -
Predicting Olive-sided Flycatcher (Contopus cooperi) Breeding Habitats in Southwestern Nova Scotia Using LiDAR Metrics Informed by Drone Data.
(2024-04)The Olive-sided Flycatcher (OSFL) is a migratory species at risk bird, currently listed as “Threatened” in Nova Scotia, and “Special Concern” federally. The strategy to promote the recovery of OSFL population is expected ... -
Predicting the frequency of storm surges and extreme sea levels in the northwest Atlantic
(2006-10)[1] A 40 year hindcast of storm surges in the northwest Atlantic and adjacent shelf seas is performed using a 2-D nonlinear barotropic ocean model forced by realistic 6 hourly winds and air pressures. This hindcast is used ... -
Predicting wave dislodgment of mussels: variation in attachment strength with body size, habitat, and season
(2001)Breaking waves impose large hydrodynamic forces which may dislodge mussels and other organisms living on exposed rocky shores. We examined the effect of variation in attachment strength with size, habitat and season on ... -
Prediction of surface currents and drifter trajectories on the inner Scotian Shelf
(2003-09)The predictive skill of a simple model of surface flow on the Scotian Shelf is assessed using oceanographic data collected in February 1996. The model is forced by wind stress, water density, and sea level along the open ... -
Preferential recycling of nutrients - the ocean's way to increase new production and to pass nutrient limitation?
(1999-12)Uptake of atmospheric CO2 by the oceans and the export of carbon into deeper waters via the biological CO2 pump is driven by the production of particulate organic matter (POM). The elemental ratios of carbon, nitrogen, and ...
