Abstract
The Arctic region experiences global warming at a much faster pace than the rest of the globe, showing a temperature increase of 0.75°C over the past decade alone. Affected by the implications of climate change are a key ecological group: Arctic arthropods, who are vital to the dynamics of the Arctic food web and ecological functioning. Samples from pitfall traps, collected on Svalbard during the years 2008-2018 were used to form a large dataset, and the effect of annual values of temperature and precipitation on the average abundance of Arctic arthropods was studied. The biggest impacts of temperature, as well as precipitation, were seen in the springtail family Hypogastruridae. During the studied years, the abundance of Chironomidae, Sciaridae, and Araneae seem to be repressed by rising temperatures and more precipitation, while the abundance of Mycetophilidae seems to increase. For 6/10 groups, an in-depth comparison between two years that differed in mean temperature and precipitation showed alternative results than when looking at the trend of these groups in the ten-year dataset, indicating a wide range of intra- and inter-season variability affected by day-to-day weather changes.
