Evaluation of species specific success for fish passing through fishways

Irving Oil Ltd. (IOL) manages impounded wetlands on company owned properties including a wetland located on the Little River at the site of the Saint John Oil Refinery. IOL in partnership with Ducks Unlimited Canada (DUC) manages this wetland and other impoundments to provide proper habitat for wildlife including fishes and ducks. To do this this IOL must know the most cost effective way to manage physical factors (i.e., water flow and temperature, fishway structure) that affect the viability of wildlife in its wetlands. Adjusting physical variables is costly, both in capital costs (i.e.

Assessing and improving the analysis of migration count data for population monitoring

Counts of birds passing a geographic location during migration to or from their breeding grounds are often used to estimate long-term population change. However, birds often stop at count sites for several days to fatten for their next migratory flight, affecting probability of detection. The migratory path followed might also vary among years. The influence of such factors on population estimates are unknown.

An individual-based model of the Cape Breton Island American marten (Martes mericana) population and habitat usage of released individuals

The American marten is a mink sized member of the weasel family. The Cape Breton Island population is believed to consist of fewer than 50 individuals. The Nova Scotia Department of Natural Resources (NSDNR; partner organization) have already begun efforts to augment the population in association with other partners. Individual based models (IBMs) are used to simulate population level processes (e.g. persistence, distribution) through cumulative individual life histories (e.g. reproduction, dispersal, mortality) in a virtual habitat.

User Modelling and Feature Selection for Personalized Local Search

Search engines, such as Google, have revolutionized the way we search for electronic information, providing a user with a ranked list of documents most relevant for a particular query. This project with GenieKnows R&D, a search engine company, concerns an extension of this basic technology, in which the goal is to incorporate geographic constraints into the search (e.g. find coffee shops near the Halifax Citadel). An additional challenge is to learn and incorporate user preferences when ranking the results returned.

Mathematical Methods for Monitoring and Controlling Mite Infestations in Apple Orchards

Various species of mites pose significant challenges for apple growers worldwide. In order to control the mite infestations, miticides can be sprayed or predators can be introduced. The latter option leads to a complex ecology characterized by predator-prey relationships. Multiple species, with varying behaviours, give rise to complex population dynamics that must be better understood if apple growers are to prevent damage to their orchards effectively.

Researching Organic Materials to Control Fruitset of Apples

The project will utilize basic research to understand the target and time of action of the organic materials which will be used to guide the implementation and management plan for a new blossom thinner. The intern will test the efficacy of twenty candidate organic materials to act as blossom thinners and develop a management plan for the application of the materials with respect to timing and concentration at which they should be employed.

High-resolution Light Detection and Ranging (LiDAR) and its Application to Salt Marsh Restoration

Salt marshes are recognized as significant feeding grounds and refuges for wildlife and for their importance in flood mitigation, carbon sequestration and as filters for removing pollutants and suspended sediments. With growing interest in, and efforts towards, dyke removal and salt marsh restoration, there is a need for science-based management decisions to ensure appropriate site-specific restoration activities.

Rapid Detection of Salmonella Species in Composted Biosolids Using Real-time Polymerase Chain Reaction

The intern will assist the Greater Moncton Sewerage Commission (GMSC) in the development and production of biologically-safe composts from biosolids by providing novel technologies to assess its biosafety. To achieve this, the intern will develop molecular tools, based on the real-time polymerase chain reaction (PCR) technology, to allow quick, accurate and reliable detection of human microbial pathogens directly from compost using specific DNA primers.

Statistical Modelling for Nursing Human Health Resources

This research project is part of a research study funded by the Ministry of Health and Long-term Care in Ontario. It examines the relationship among nursing service utilization, patient outcomes and population health care needs in long-term care/chronic care and community care/home care sectors in Ontario. It seeks to provide a needs-based Health Human Resources Planning approach to help policy makers in developing human resource strategies that target the nursing shortage and respond to the changing needs of the population over time.
