Alewife (Alosa pseudoharengus) is a key species in the ecology of the upper Bay of Fundy, Canada, that provides food to numerous predators and scavengers. Each year, Alewife migrate into freshwater systems to spawn in lakes. Dams and fishways often impede the migration of Alewife, which can have detrimental effects on Alewife populations, as well as nutrient exchange between marine and freshwater ecosystems.
Treatments that involve activating a patients own immune system, immunotherapies, are becoming important cancer therapies. Unfortunately, doctors dont always know the best way to combine these therapies to best treat patients and the current tools they have to evaluate treatment success dont work well for immunotherapies. Molecular imaging, particularly magnetic resonance imaging (MRI) or positron emission tomography (PET) can help researchers learn more about how these therapies work and how best to combine them.
The collection of bacteria and archaea in an ecosystem is termed the microbiome. This microbiome is critically important to the structure and function of essentially any ecosystem, providing many ecosystem services, such as growth promotion, nutrient turnover, and impacts on organismal health. The vast majority of these organisms, however, are unknown to science for a variety of reasons. Recent advances in high-throughput DNA and RNA sequencing of environmental samples provide a significant data resource to help understand these organisms.
Canadas coastal regions are an excellent source of marine renewable energy. These regions are also popular with marine mammals, providing good feeding opportunities. However little is known about how marine mammals will be affected by tidal energy developments. Concerns include the impacts of sound on animals ability to find food and navigate, the indirect effects of changes in prey distribution and abundance, and the direct impacts of collision with tidal energy structures in the water column.
Administration of supplemental oxygen through medical air is a life-supporting measure essential for the management of severe primary respiratory conditions as well as secondary lung injury due to systemic insults such as trauma and sepsis. This medical air is often produced on site through devices which draw, compress and filter outside air in order to redirect it into buildings. However, depending on the outdoor conditions, the state of the ventilation system or the presence of microorganisms, this air can be contaminated.
Re-establishing salmonid populations to areas historically occupied has substantial potential for conservation gains, however, such interventions also risk negatively impacting native resident stocks. An on-going reintroduction of anadromous sockeye salmon (Oncorhynchus nerka) to Skaha Lake, British Columbia is succeeding, with large numbers returning to spawn. However, a recent genetic study detected strong evidence of hybridization and introgression with native kokanee (freshwater obligate form of O.
Within a watershed, data are collected on various aspects of water (amount, withdrawals, returns, contaminant concentrations) by multiple groups, yet rarely shared at the basin scale. To reduce data siloing and make collected data available to multiple users interested in water management within a watershed context, data from multiple sources must be combined.
Humpback whales show remarkable recovery after the impacts of commercial whaling, and their consumption of essential food resources could affect local herring and salmon populations. Little is known about the feeding ecology of humpback whales in BC waters, despite their increasing importance to fisheries and tourism. Both humpback whales and fish are vulnerable to prey depletion, and the public have a vested interest in the future of humpbacks and fisheries in BC.
It is critical for consumers to be assured that Natural Health supplements being purchased commercially are of high quality and contain the ingredients as listed on labels. For regulatory agencies to make such assurances, it is important that third-party product testing be carried out to identify the presence of the appropriate botanicals and their active ingredients. This project will begin to address the need for standardized authenticated reference materials from which appropriate quality control tests can be developed.
