Tropical lowland insects face mass die-offs as climate change pushes temperatures beyond their heat tolerance.
A new study reveals tropical lowland insects, vital to ecosystems, have limited ability to adapt to rising temperatures, with up to 52% of future surface temperatures in the Amazon potentially causing heat-related death in half the studied insect community.
Unlike some high-altitude species, lowland insects show little physiological flexibility in heat tolerance, constrained by stable protein structures that limit evolutionary adaptation.
The research, based on over 2,000 species across Africa and South America, warns of widespread insect die-offs due to climate change, threatening pollination, decomposition, and food webs.
Los insectos de las tierras bajas tropicales se enfrentan a una muerte masiva a medida que el cambio climático empuja las temperaturas más allá de su tolerancia al calor.
