Arctic marine ecosystems are changing, one aspect of which appears to be distributional expansions of sub-arctic species. For Arctic marine systems, there is limited occurrence information for many species, especially those found in restricted habitats (e.g., ice-covered, far north, or deep-water). Increasing observations through on-going Fisheries and Oceans Canada (DFO) community-based monitoring programs (e.g., Arctic Coast, Cambridge Bay Arctic Char stock assessment, Arctic Salmon, and Kugluktuk coastal surveys), community observation networks, and local media have augmented opportunities to document new occurrences of marine fishes. Combined data from historical records and contemporary observations at the local scale can then delineate these among three types of occurrences: gradual distributional expansion, episodic vagrants, and rare endemics. Here we document nine occurrences of unusual sightings across six fish species (Pink Salmon Oncorhynchus gorbuscha, Bering Wolffish Anarhichas orientalis, Greenland Shark Somniosus microcephalus, Broad Whitefish Coregonus nasus, Banded Gunnel Pholis fasciata and Salmon Shark Lamna ditropis) from six northern Canadian communities and classify the nature of each observation as rare, vagrant, or expanding distributions. Uniting scientific and local observations represents a novel approach to monitor distributional changes suitable for a geographically large but sparsely populated area such as the Canadian Arctic. The new occurrences are important for discerning the potential effects of the presence of these species in Arctic ecosystems. These observations more broadly will build on our understanding of northern biodiversity change associated with warming Arctic environments.

Throughout 2018, approximately 68.5 million people were forcibly displaced due to armed conflict, generalized violence, or human rights violations around the world; of those, 40 million were internally displaced persons (IDP), 25.4 million refugees, and 3.1 million asylum-seekers. Effective management of refugee and IDP camps rely on accurate, up-to-date, and comprehensive population estimates. However, obtaining this information is not always easy. Thus, the purpose of this study was to develop a methodology and custom toolset that estimates populations based on dwellings derived from automated feature extraction of high-resolution, multi-spectral orthorectified imagery. Estimates were determined for five Rohingya refugee camp populations and compared with United Nations High Commissioner for Human Rights (UNHCR) baseline data to determine accuracy.

In the absence of a binding and coherent international migration regime, the global governance of migration relies on normative narratives produced by UN agencies and other intergovernmental forums, in line with the discursive legitimacy traditionally associated with international organizations. Such narratives impact migrants, asylum-seekers, and refugees because they support certain policy frameworks among member states. Yet, global migration governance remains fragmented, especially as far as the long-standing divide between the International Organization for Migration (IOM) and the Office of the United Nations High Commissioner for Refugees (UNHCR) is concerned. This article contributes to this discussion by applying corpus-assisted critical discourse analysis to the narratives produced by these two organizations. The article identifies some of the dominant worldviews in the narratives of IOM and UNHCR. Results show that IOM and UNHCR have distinct worldviews, associated with different textual patterns, and that, while IOM’s textual productions seem to influence UNHCR’s discourses, the opposite is less true. This would support the view that IOM is currently the leading actor in terms of framing migration, thereby exerting a strong influence on global migration governance.
