Executive Summary
Studies show plants and polar bears are using epigenetic, genetic, and hybrid changes to cope with warming, but extreme heat can still outpace adaptation.
- Plants can pass stress responses to offspring through epigenetic inheritance
- Stress marks are filtered by enzymes such as ROS1 and DDM1 during seed development
- The framework links drought, heat, competition, and herbivory to heritable changes
- Epigenetic buffering may reduce selection pressure and slow DNA-based adaptation
- Altered plant chemistry may affect decomposition, nutrient cycling, and ecosystems
- Arabidopsis evolved across 30 climate zones, but some hot-site populations went extinct
- Polar bears in southeast Greenland show DNA changes linked to heat stress and diet shifts
Quick Facts
- What: Climate stress is driving epigenetic and genetic change
- Where: Plant studies span global test sites and Arctic Greenland
- Why: Warming conditions are altering survival, evolution, and ecosystems
- Who: Researchers studying plants and Arctic wildlife adaptation
- When: Findings reported in recent published studies
