Shellfish aquaculture activities that occur in the intertidal environment can directly and indirectly affect the organisms that live on and within the sediment and higher trophic level organisms (e.g. fish) that utilize the habitat.
Osteoarthritis is a major obstacle to work productivity and quality of life for many Canadians, affecting over 10% of the general population and 15% of Saskatchewanians, with the elderly increasingly affected (>40% of Canadians over 65 years old). At the cellular and molecular level, osteoarthritis involves two main defects: 1) degradation of sugar-coated proteins (proteoglycans) in the cartilage that protects bones at the joints, and 2) changes to gene expression in the cells (chondrocytes) that maintain cartilage.
Deadwood, being standing (snags) or fallen, represents a key structural element in forest ecosystems. Many flora and wildlife species are directly associated to deadwood for establishment and growth in plants and feeding or nesting in animals, including cavity-tree nesters (primary excavators and seconday users).
Comparison of in vitro vs. in vivo formation of cis-platin DNA adducts
INTRODUCTION: More than 50% of the compounds used in chemotherapy damage DNA. The most effective chemotherapeutic compounds induce DNA lesions that are slowly repaired, blocking DNA replication and cell cycle over a relatively long period of time after treatment. However cell cycle arrest induces events that promote DNA repair, making cells resistant to chemotherapeutic drugs. Among the most difficult DNA lesions to repair are DNA interstrand-crosslinks.
Migratory birds are in a conservation crisis, with accelerating population declines documented Canada-wide. It is a federal responsibility to protect migratory birds; however, a major gap in the ability to mitigate threats to these species is a lack of knowledge of their year-round movements. By using new tracking technology, our project will quantify movements and migrations of declining songbirds and fill knowledge gaps critical for informing conservation activities. Bird Studies Canada (BSC)s mission is to engage citizens in understanding and conservation of birds.
Domestication of cats is thought to date to the Neolithic and to have been driven by the need to control rodents that destroyed stored food. In developed countries, modern pest control methods have rendered the traditional role of cats largely redundant and the hunting tendency of cats is now viewed in a more negative light as contributing to the decline of birds. However, increasing residential use of formerly agricultural and wild areas are leading to increased human and wildlife contact.
Transitions between adjacent plant communities are important features of landscapes that might harbour greater diversity. However, forest edges created by human activities can have negative consequences for wildlife habitat. Both types of transitions dominate fragmented agricultural landscapes in tropical forests. Understanding the vegetation structure in such heterogeneous landscape could help predict animal movements across natural and anthropogenic transitions.
Intern will be determining active ingredients in Iceberg mist which is a toner based on iceberg water. Several tests will be conducted to determine the antioxidant potential of this product. The partner organization will be able to make a claim on the product using the information based on this project which will help in marketing and sales. Intern will also study antioxidant enzyme activities as well as antioxidant metabolites in other botanical samples including some specific berries and their leaves. Chaga and Birch sap will also be studied for their antioxidant potential.
Biobased products, mostly derived from plant biomass, have the potential to improve the sustainability of Canadas natural resources and environmental quality while competing economically. Plant biomass, composed primarily of cell walls and modification of cell wall properties has the potential to improve biomass conversion to biobased products such as biofuels. Progress towards achieving this goal is currently impeded by a lack of knowledge of how cell walls are assembled and how their structure affects the processing of biomass.
This UBC-Okanagan research will contribute to the optimization of novel composite bio-mineral fertilizers for sustainable agriculture, pollution remediation and other environmental applications. The production processes and formulas of these product prototypes have been developed and protected through patent filings by principals of Avalon Alliance Inc., for the commercial applications of subsidiary Avalon Bio-Mineral Technologies Inc.
