Reduced Representation and Whole-Genome Sequencing Approaches Highlight Beluga Whale Populations Associated to Eastern Canada Summer Aggregations.

Effective conservation strategies inherently depend on preserving populations, which in turn requires accurate tools for their detection. Beluga whales () inhabit the circumpolar Arctic and form discrete summer aggregations. Previous genetic studies using mitochondrial and microsatellite loci have delineated distinct populations associated to summer aggregations but the extent of dispersal and interbreeding among these populations remains largely unknown.

The academic impact of paediatric research agendas: a descriptive analysis.

Background: Increasingly, researchers are involving children and young people in designing paediatric research agendas, but as far as we were able to determine, only one report exists on the academic impact of such an agenda. In our opinion, the importance of insight into the impact of research agendas designed together with children and young people cannot be overstated. The first aim of our study was therefore to develop a method to describe the academic impact of paediatric research agendas.

Elucidating the sustainability of 700 y of Inuvialuit beluga whale hunting in the Mackenzie River Delta, Northwest Territories, Canada.

Beluga whales play a critical role in the subsistence economies and cultural heritage of Indigenous communities across the Arctic, yet the effects of Indigenous hunting on beluga whales remain unknown. Here, we integrate paleogenomics, genetic simulations, and stable C and N isotope analysis to investigate 700 y of beluga subsistence hunting in the Mackenzie Delta area of northwestern Canada. Genetic identification of the zooarchaeological remains, which is based on radiocarbon dating, span three time periods (1290 to 1440 CE; 1450 to 1650 CE; 1800 to 1870 CE), indicates shifts across time in the sex ratio of the harvested belugas.

Involving children and young people in paediatric research priority setting: a narrative review.

Objective: The objective of this study is twofold: first, to describe the methods used when involving children and young people (CYP) in developing a paediatric research agenda and, second, to evaluate how the existing literature describes the impact of involving CYP. We distinguish three forms of impact: impact on the research agenda (focused impact), impact on researchers and CYP (diffuse impact) and impact on future research (research impact).

Design: A narrative review of MEDLINE, PsycINFO, Web of Science and Google Scholar was conducted from October 2016 to January 2022.
