Climate Change Affecting Spring Activities: Arthropods, Birds, and Plants in Northeast Greenland Face Increased Challenges

Anemones, gnats, and crickets are experiencing fluctuations in their behavior due to climate warming. While the trend is overall warming, the timing of spring events such as flowering, insect awakening, and egg-laying varies significantly from year to year. This variability presents challenges for both plants and animals. In colder winter years, these activities become more difficult and costly.

The North and Arctic regions face particularly tough selection situations due to the rapid warming of land areas. Researchers have been monitoring the spring activities of plants, arthropods, and birds in Northeast Greenland for the past 25 years. The study region includes the North Arctic region, Svalbard, Arctic Ocean islands, and the northernmost coasts of Siberia and Canada. The research has shown that while there is an overall warming trend, the timing of spring events varies significantly from year to year.

Around 20 species or groups of organisms were monitored in the study, including Lapland’s anemones, tundra willows, ticks, gorse hawks, barn owls, and wagtails. The researchers found that the trend observed in the first ten years of the study where springs were warming steadily did not continue in later years. The variability in spring events surprised the researchers who had expected a more consistent advancement in plant and animal activities. The results were published in Current Biology.
