Article Synopsis
- Current knowledge about how extreme temperatures affect alpine evergreens in Mediterranean climates is lacking, highlighting the vulnerability of these biodiverse ecosystems under climate change.
- The study focused on the thermal sensitivity of a key evergreen species in the Teide mountain, revealing that mature leaves are more susceptible to moderate heat compared to other alpine plants.
- It was found that young leaves possess greater freezing tolerance than mature leaves in spring, indicating a potential resilience to late-frost events, yet mature leaves are particularly vulnerable to rising temperatures.
In Antarctica, multiple stresses (low temperatures, drought and excessive irradiance) hamper photosynthesis even in summer. We hypothesize that controlled inactivation of PSII reaction centres, a mechanism widely studied by pioneer work of Fred Chow and co-workers, may effectively guarantee functional photosynthesis under these conditions. Thus, we analysed the energy partitioning through photosystems in response to temperature in 15 bryophyte species presenting different worldwide distributions but all growing in Livingston Island, under controlled and field conditions.
