A study published in *Ecography* reveals how climate change is reshaping predator-prey interactions in the semi-arid Bosque Fray Jorge National Park in Chile.

Over 24 years (1990–2015), researchers observed that reduced precipitation during dry periods forced owl species to shift their prey choices, decreasing dietary overlap.After 2003, owls began incorporating new prey species into their diets, increasing prey diversity in the ecosystem.Temperature emerged as the primary driver of these changes, with warmer conditions influencing prey availability and owl foraging behavior.

The study highlights that climate-driven shifts in resource availability are destabilizing ecological networks, potentially impacting ecosystem resilience.

Lead author Angéline Bertin notes that as climate change intensifies, understanding these dynamics will be critical for predicting how ecosystems adapt to environmental stressors.

The findings underscore the interconnectedness of climate patterns, food webs, and biodiversity, emphasizing the need for long-term ecological monitoring to safeguard ecological stability.
