A recent study published in the journal Physiologia Plantarum has uncovered how two of the only native flowering plants in Antarctica are responding differently to long-term warming. The research, conducted over seven years by scientists from Chile and Spain, focused on Deschampsia antarctica (Antarctic hairgrass) and Colobanthus quitensis (Antarctic pearlwort), the only two flowering plants found in the region. The study took place on King George Island, near the Polish Antarctic Station Henryk Arctowski, with experiments beginning in 2012. The findings reveal that D. antarctica has adapted by reducing its leaf hydraulic conductivity and photosynthetic rate. This means the plant is using less water and producing less energy through photosynthesis, which the researchers see as a strategy to conserve resources in a warming climate. In contrast, C. quitensis increased its hydraulic conductivity, photosynthetic capacity, and the elasticity of its cell walls, allowing it to better transport water and carbon dioxide. These changes were also supported by structural adaptations, such as a cushion-like growth form that helps retain heat. Dr. Patricia Sáez from Universidad de La Frontera and Dr. Lohengrin Cavieres from Universidad de Concepción explain that both species face the challenge of maintaining a balance between water transport and photosynthesis, which is crucial for their survival. However, each species has taken a different approach: D. antarctica focuses on stability and safety, while C. quitensis emphasizes flexibility and the ability to quickly adapt to changing conditions. This study is the first to examine both leaf hydraulic traits, the structure of the plant’s vascular system, and photosynthetic performance in these species under long-term warming. The researchers say this method allows them to study real-world impacts of climate change, such as more frequent freeze-thaw cycles, rather than just focusing on average temperature increases. They suggest that the different strategies used by the two species may explain how they can coexist and thrive in Antarctica despite the region's warming climate. The study highlights that there is no one-size-fits-all response to climate change, and the variety of strategies likely contributes to the plants’ success in one of the harshest environments on Earth.
