‘Nature Under Siege’: Insect Populations Declining Due To Climate Change

‘Nature Under Siege’: Insect Populations Declining Due To Climate Change

In 2020, biologists Daniel Janzen and Winnie Hallwachs decided to extend their annual six-month stay in Costa Rica for ecological research due to COVID-19 restrictions. With extra time on their hands, they reflected on the declining insect population caused by the “heterogeneous blanket” of climate change. While their primary field of research is not climate change, the toll it takes on ecosystems was hard to ignore. The biologists noticed that rising temperatures led to disturbances in the insect population, affecting food webs from the bottom up.
