Weather’s Role in Insect Decline
Weather explains the decline and rise of insect biomass over 34 years
Insects play a crucial role in ecosystems, but there has been a significant decline in their biomass in Central Europe and other regions. A study reanalyzed 27 years of insect data and found that this decline is strongly influenced by complex weather conditions. Contrary to previous beliefs, climate change can have a substantial impact on insect populations in temperate zones. While recent years showed a slight increase in insect biomass, ongoing climate change could still pose a threat. The study underscores the importance of researching how annual weather conditions affect insect populations.
