We describe the main features of LT variability that influence native vascular plants in the Antarctic and examine the relationship between the temperature regime at the micro-level and meteorological conditions at the macro-level. We used a period of over a year, during which 37 specialized mini-loggers recorded LT near vascular plants in the Argentine Islands–Kyiv Peninsula region of the Antarctic Peninsula. Rather than measuring standard air or soil temperature, these loggers detect the temperature near the ground, in the microhabitats that harbour vascular plants. On a daily scale, LT correlates with standard (2-m) air temperature, with the values higher at …

Louise Boyd (1887–1972) was a female pioneer in Arctic research whose legacy includes the exploration of north-east Greenland. In this Perspective piece, we use a broad interdisciplinary approach to investigate her career as a photographer and expedition leader. When documenting glacial retreat during the 1930s, she was at the forefront of the development of glaciology as a research discipline. Without family obligations and with seemingly inexhaustible financial resources, she used Arctic exploration to create an independent and self-defined life for herself.

Cooperation in the Arctic region has been fruitful in the past few decades, generating several multilateral organizations and forums covering the entire circumpolar North. In many cases, forums were created to serve as catalysts, bringing together decision-makers from different backgrounds in a conference setting to promote dialogue and the exchange of ideas. To enquire about the possibility of creating a forum of cooperation in the eastern North American Arctic, a total of five governmental officials from Canada, Denmark, Nunavut, Québec and Greenland, and one elected representative from Greenland were interviewed with the same set of five questions. The governmental officials …

Herein we describe mating behaviour observed in a group of 20 white whales in Svalbard, Norway. A single female was the centre of attention during the 45-minute encounter, which was observed, photographed and videotaped at an ice edge in Storfjorden in June 2022. Several males surrounded the female and vigorously herded her from all sides. The female spy-hopped regularly, and sometimes her whole body was pushed out of the water by the other animals. High tail-lifts and tail-slapping were frequently performed by males, and erect penises were observed many times. Trumpet calls were also heard. At one point, three males …

The Spitsbergen population of bowhead whales (Balaena mysticetus) was harvested to near extinction during the whaling era. Here, we show possible signs of recovery of the population by reporting observations of two calves in the Scoresby Sund polynya in East Greenland on 2 and 4 May 2022, and it is the first observation of this kind in this area since the early 1900s.
