Regular light-dark cycles greatly affect organisms, and events like eclipses induce distinctive physiological and behavioral shifts. While well-documented in animals, plant behavior during eclipses remains largely unexplored.

Scientists monitored spruce trees to assess their bioelectrical responses to a solar eclipse and discovered trees anticipated the eclipse, synchronizing their bioelectrical behavior hours in advance. Older trees displayed greater anticipatory behavior with early time-asymmetry and entropy increases. A ground breaking international study has revealed spruce trees not only respond to a solar eclipse but actively anticipate it by synchronising their bioelectrical signals hours in advance into a cohesive, forest-wide phenomenon. Scientists monitored spruce trees to assess their bioelectrical responses to a solar eclipse and discovered trees anticipated the eclipse, synchronizing their bioelectrical behavior hours in advance. Older trees displayed greater anticipatory behavior with early time-asymmetry and entropy increases., shows older trees exhibit a more pronounced early response, suggesting these ancient sentinels retain decades of environmental memory and may use it to inform younger trees of impending events. This study adds to the emerging evidence that plants are active, communicative participants in their ecosystems, capable of complex, coordinated behaviours akin to those seen in animal groups. The lead authors are Professor Alessandro Chiolerio of the Italian Institute of Technology and University of the West of England, and Professor Monica Gagliano from Southern Cross University, Australia. "This study illustrates the anticipatory and synchronized responses we observed are key to understanding how forests communicate and adapt, revealing a new layer of complexity in plant behaviour," said Professor Gagliano.Using custom-built, ruggedised low-power sensors deployed across a forest in the Dolomites , the interdisciplinary team -- comprising experts from Italy, the United Kingdom, Spain, and Australia -- recorded simultaneous bioelectrical responses from multiple trees. Their analysis demonstrates that individual trees' electrical activity became significantly more synchronised before and during the eclipse, indicating that trees function as a unified living system that coordinates its response to external events. "By applying advanced analytical methods -- including complexity measures and quantum field theory -- we have uncovered a deeper, previously unrecognised dynamic synchronisation not based on matter exchanges among trees," said Professor Chiolerio. "We now see the forest not as a mere collection of individuals, but as an orchestra of phase correlated plants.""The fact that older trees respond first -- potentially guiding the collective response of the forest -- speaks volumes about their role as memory banks of past environmental events. "This discovery underscores the critical importance of protecting older forests, which serve as pillars of ecosystem resilience by preserving and transmitting invaluable ecological knowledge," said Professor Gagliano.
