The project will reformulate the coronavirus dispersal hypothesis to food web disturbance caused by ‘social mood’ of human behaviors. We will develop a dynamic system-theoretic model to capture the change pattern of such a “social mood” and identify early warning indictors. The approach will be an advance for understanding the pathogen dispersal risk among those known- and unknown- susceptible species along the food web. This will be very important for contingency plans of COVID-19, especially in travel recommendations and pathogen containment.
A swarm of robots should be available on the board of a vessel or oil rig so they will be deployed when spill occurs. Based on our existing know-how knowledge and technology, the swarm of robots automatically detect the boundary of the oil, then they deploy inflatable booms to contain the oil. After they successfully contain the spill by detecting whether or not the booms achieve a close loop, the swarm continues to expand its searching area until it could not find any new spill.
The rapid expansion of the aquaculture industry has fueled significant advances in fish health and nutrition. One such innovation has been the development of the growth-enhanced Atlantic salmon, AquAdvantage Salmon (AAS), which was approved for commercial production and consumption in the US in 2015. AquAdvantage Salmon are raised exclusively in land-based operations using highly efficient recirculating aquaculture systems (RAS) that depend on microbial communities to degrade waste and excess feed.
The general aim of this proposal is to discover new natural products with antiviral activity against the coronavirus SARS-CoV-2, which is responsible for the current COVID-19 global pandemic. Our lab has a collection of ~ 7,000 unique bacteria and fungi derived from marine sources that we will use to screen for the production of antiviral compounds. While we do not have the lab infrastructure to directly grow SARS-CoV-2, we will use distantly related human coronaviruses to complete this project.
Rapid prototyping, or 3D printing, has inspired the imagination of the general public, from simple build-it-yourself “hobby” machines using polymer-based binder material with inkjet functionality, to portable printers that can fashion components in zero gravity on the International Space Station. The functionality is user-friendly, in that printed material is dropped onto a substrate in viscous plastic form, which solidifies to take on the designed shape.
In the context of ocean sustainability of west coast of Canada, some questions that need to be considered are: what is the significance of environmental indicators related to the impact on marine aquatic species? How can changes in environment be predicted by patterns of bioindicators, for example as a result of hypoxia, affecting farmed and wild salmon? A starting point to answer these questions is the development of a centralized, common, accessible database that documents the shift in marine observation metadata collected in the area.
The proposed research investigates an opportunity of monitor, measure, and model the role of carbon sequestration and emission of carbon dioxide from agricultural soils of Atlantic Canada. Precision agricultural practices will be designed to promote sustainable agriculture in Atlantic Canada.
The goal is to help understand the effects of cold water temperatures, and the infiltration of sediment from agriculture on the survival of Atlantic salmon from egg to juvenile in PEI. Three rivers on PEI will be studied that have a range of fair to excellent Atlantic salmon populations. Total year class failure has been noted on more than one occasion over recent years and understanding the cause will be implement to help address this major population limiting factor.
Diadromous native salmonid species in coastal areas have been impacted by a multitude of factors including poor fish passage for over a century, and by an introduced salmonid, the rainbow trout. The overall goal of this study is to examine the impact of fishway improvement and anadromy, or the lack thereof, on brook trout populations. This research will provide data to inform coastal restoration efforts, particularly fish passage/fishway design, and generate new knowledge useful to the assessment environmental flows and the impacts of the introduction of non-native fish species.
