The Canadian Genomics Research and Development Initiative for Antimicrobial Resistance (GRDI-AMR) uses a genomics-based approach to understand how health care, food production and the environment contribute to the development of antimicrobial resistance. Integrating genomics contextual data streams across the One Health continuum is challenging because of the diversity in data scope, content and structure. To better enable data harmonization for analyses, a contextual data standard was developed.

A global decline in seagrass populations has led to renewed calls for their conservation as important providers of biogenic and foraging habitat, shoreline stabilization and carbon storage. Eelgrass () occupies the largest geographic range among seagrass species spanning a commensurately broad spectrum of environmental conditions. In Canada, eelgrass is managed as a single phylogroup despite occurring across three oceans and a range of ocean temperatures and salinity gradients.

Article Synopsis
  • Complex traits like age at maturation in Atlantic Salmon involve complex genetics influenced by evolutionary variations and different types of genetic sweeps.
  • Research on North American Atlantic Salmon suggests a genetic parallel to European populations with identified large-effect loci, but variations exist based on sex and geographic location.
  • Despite low levels of genetic similarity across populations, consistent molecular pathways related to sea age have been identified, highlighting a mix of shared and unique genetic influences.

Lumpfish, , have historically been harvested throughout Atlantic Canada and are increasingly in demand as a solution to controlling sea lice in Atlantic salmon farms-a process which involves both the domestication and the transfer of lumpfish between geographic regions. At present, little is known regarding population structure and diversity of wild lumpfish in Atlantic Canada, limiting attempts to assess the potential impacts of escaped lumpfish individuals from salmon pens on currently at-risk wild populations. Here, we characterize the spatial population structure and genomic-environmental associations of wild populations of lumpfish throughout the Northwest Atlantic using both 70K SNP array data and whole-genome re-sequencing data (WGS).

Article Synopsis
  • - Environmental variation plays a crucial role in the diversity of marine species like cunner, a temperate reef fish, yet there is limited understanding of how genomic and ecological factors shape their populations.
  • - A comprehensive genome assembly of cunner revealed significant genetic variation across 803 individuals from 20 locations and indicated the existence of four regional population groups in the Northwest Atlantic.
  • - Findings suggest that environmental factors, particularly benthic temperature and oxygen levels, influence genetic structure, providing valuable insights for the management and conservation of cunner in aquaculture and wild settings.
