Drought is a major abiotic stress that affects plant growth and productivity. In this study, we investigated the ecophysiological responses of two fern taxa, Dryopteris cochleata and Hypodematium crenatum, to drought stress. We evaluated the photosynthetic pigments and cell membrane permeability, and examined their stability under hyperthermia stress. Our results showed that both fern taxa were able to maintain their photosynthetic pigments under hyperthermia stress. However, their cell membrane permeability increased significantly under drought stress, with a greater increase observed in Dryopteris cochleata compared to Hypodematium crenatum. These findings suggest that Hypodematium crenatum may have a better ability to cope with drought stress compared to Dryopteris cochleata. Hyperthermia, or high temperature stress, can have negative effects on the ecophysiology of ferns, including a decrease in photosynthetic pigments and membrane stability. These findings are particularly important in the context of climate change, as rising temperatures are expected to become more frequent and intense in many regions of the world. These studies emphasize the importance of mitigating the effects of climate change in order to preserve the ecological roles and functions of ferns and other plant species.
