Rapid Weather Fluctuations pose Challenge for Plants and Animals in the Arctic: Study Reveals Spring Awakening Variability

In the rapidly changing climate, anemones, gnats, and crickets are experiencing a rollercoaster of ups and downs. While spring is generally earlier and milder on average, it still comes with storms and snow to contend with. This variability in weather poses a challenge for both plants and animals. Plants need to sprout early to thrive in warm conditions, while insects need enough food to take flight and birds need the right conditions to lay eggs. In colder winters, activities like sledding become less accessible.

Organisms in the North and Arctic regions face particularly tough selection situations due to rapid warming land areas. Spring fluctuations play a crucial role in determining the activity of organisms as reported by an international group of researchers in the science magazine Current Biology. The data from 1996 to 2020 shows that while there has been an overall warming trend, the variability in spring warmth and snowfall has been significant. The advancement of flowering, insect awakening, and egg-laying varies greatly among the species studied including Lapland’s anemones, tundra willows, ticks, gorse hawks, barn owls, and wagtails.

The findings of this research may come as a surprise as the trends in the first ten years of monitoring were different from those in the following years. The researchers anticipated that as time passed, the attention of plants and animals may shift due to changing spring dynamics. This study was published in the journal Science in Nature in March 2024 sheds light on how organisms in Arctic regions adapt to a changing climate.

In Northeast Greenland for instance, researchers have been monitoring the spring activity of plants arthropods birds for over 25 years now. Their data shows that while there has been an overall warming trend since 1996 to 2020; variability in spring warmth snowfall has also been significant among species such as Lapland’s anemones tundra willows ticks gorse hawks barn owls wagtails.

This study highlights how complex it is for organisms living under rapidly changing conditions to adapt quickly enough
