This paper reports results of the first range-wide study of the behaviors of free-living wolves in the High Arctic in response to human presence and discusses these behaviors from a conservation perspective. The study focused on wolves believed to have had little, if any, contact with humans and excluded data from areas where wolves have become habituated to people. Data consisted of incidental sightings of wolves on the Canadian Arctic Archipelago and in Greenland from 1819 to 2019. A total of 325 behavioral observations were identified: 163 from Greenland and 162 from Canada. The most commonly reported behaviors (71.4%) involved wolves seeking out humans: coming to campsites, following traveling dog teams, closely approaching a person, and following people. These behaviors are not typical of canids in lower latitudes and have the potential to create conflicts with people who might feel threatened owing to the centuries-old belief that wolves are dangerous. Some Arctic wolves have been shot in perceived self-defense, when in all likelihood the animals were only curious. In addition, aggression directed towards domestic dogs was the most common form of wolf-dog interaction and produced another source of conflict. The findings are important from a conservation perspective because of the small wolf population and the fact that vanishing sea ice is increasing human access to the Arctic wolf range. Appropriate and humanely used hazing techniques and outreach to stakeholders on what constitutes normal Arctic wolf behavior can mitigate the risk of conflict and contribute to the conservation of Arctic wolves on the Canadian Arctic Archipelago and in Greenland, while minimizing the risk that the natural behavior of this subspecies is altered by increased human activity.

This paper presents the results of a number of aircraft- and boat-based surveys for seabird breeding colonies in East and North Greenland carried out in the period 2003 to 2018 and gives the first comprehensive overview of the distribution and size of the seabird breeding colonies in this remote and mainly uninhabited region. Seventeen seabird species breed in approximately 800 sites distributed very unevenly along the coasts, with high concentrations at the polynyas and long stretches with very few breeding seabirds. Climate changes are in full progress in East and North Greenland, especially affecting the sea ice regime, and seabirds are expected to respond to these changes in different ways. For example, since the 1980s, Common Eiders (Somateria mollissima) have extended their breeding range more than two latitudinal degrees towards the north, now reaching the northernmost land on Earth. Lesser Black-backed Gulls (Larus fuscus) and Great Cormorants (Phalacrocorax carbo) have immigrated, and Sabine's Gulls (Xema sabini) have increased and extended their range. Besides presenting survey results, this report may also serve as a baseline for future studies of the abundance of breeding seabirds in East and North Greenland. [ABSTRACT FROM AUTHOR]
