Summary: This study evaluates seismic intensity in the Western Canada Sedimentary Basin (WCSB) using data collected by the BC Oil and Gas Commission from 2016-2020, providing an isoseismal map for the Septimus region. The research finds that the intensity of shallow earthquakes decays more rapidly with distance compared to deeper events, highlighting the need for more systematic data collection in the WCSB.

Summary: Marine foundation species play a vital role in coastal ecosystems, and restoration of depleted populations is crucial for ecosystem function. Restoration projects for the Olympia oyster are unevenly distributed along its range, with varying goals and approaches. There is a recommendation for future investment in larger projects, which have proven to be more cost-effective, and for funders to support broader monitoring efforts to better understand the long-term effects of restoration.

Summary: Tenacibaculum is a genus of Gram-negative bacteria found worldwide. This study focused on Tenacibaculum genomes from Norway, Chile, and Canada, specifically their impacts on salmon aquaculture. The researchers used sequencing techniques to select and analyze isolates from Canadian salmon with mouthrot, discovering several known and unknown species of Tenacibaculum with potential virulence and antimicrobial resistance genes.

Summary: This study analyzed the hydrogeological characteristics of the Sunset Paleovalley in Northeast British Columbia and established a groundwater flow model to evaluate recharge magnitude and residence times. The research showed that the recharge rate and residence time of groundwater in the area are slow, which is significant for water resource management.

Summary: Competitive exclusion can lead to a loss of species diversity within small forest gaps, therefore, it is important to consider the light requirements of different tree species in mixed species regeneration following strip-cut harvesting.

Summary: This study identified several Trichoderma species from grapevines in British Columbia and evaluated their biocontrol activity against BD fungi. The results showed that these isolates were able to significantly inhibit the growth of fungal pathogens and provide protection for pruning wounds for up to 21 days. They also exhibited similar or better control compared to commercial products.

Summary: Tenacibaculum species, including T. maritimum and T. dicentrarchi, were frequently detected in commercial Atlantic salmon netpen sites, showing a ubiquitous distribution. T. dicentrarchi was found before outbreaks and T. maritimum was rarely identified. Increases in bacterial load were recorded during outbreaks, with more bacteria in summer months, suggesting a seasonal influence on tenacibaculosis. Fish mortalities were related to antimicrobial use and water quality parameters, indicating the need for further research to understand the dynamics of tenacibaculosis outbreaks.

Summary: The Liard Basin, located in Northeast British Columbia, contains significant potential unconventional gas resources and is mainly influenced by older extensional structures and Cretaceous-Tertiary compressive deformation structures, reflecting the location of these structures. Through seismic data interpretation and structural studies, the overall structural features of the basin can be obtained.

Summary: Cetaceans, spending most of their time underwater, have their year-round spatial and temporal distributions monitored through passive acoustic monitoring. This study analyzed acoustic datasets from Gwaii Haanas, a remote area in Haida Gwaii, Canada, and identified the presence of 12 cetacean species/species groups. Seasonal patterns and diel variation were observed in the acoustic signals of several species. Environmental factors were also examined for their correlation with cetacean acoustic occurrence. This study serves as a baseline for future monitoring in the area.

Summary: Climate change is affecting the distribution of marine zooplankton, with DNA analysis showing distinct genetic differences in the Acartia tonsa species in the northeast Pacific. During warm phases, southern populations migrate north, as indicated by anomalies in A. arbruta biomass correlated with the Pacific Decadal Oscillation.

Summary: Red alder trees are an important part of coastal stream communities in the Pacific Northwest. However, canopy dieback has been observed in red alder for several years. Through investigations of symptomatic trees in Vancouver, Canada, three pathogenic Phytophthora species were identified, with P. pseudosyringae being the only species capable of causing both stem canker and aerial symptoms. Additionally, a non-lethal species, P. gonapodyides, was found to be more aggressive than the pathogenic species tested. These results reveal a greater complexity in red alder decline than previously suspected.

Summary: This study presents detailed velocity and density models for the Montney unconventional resource play in northeast British Columbia, Canada, which are essential for accurate hypocenter determination and analysis of induced seismicity processes. The models demonstrate tighter clustering of event locations and significantly improved depth resolution compared to traditional models, resulting in a median focal depth consistent with hydraulic-fracturing completion depths.
