In the dry landscapes of north-central Chile, a large rainfall unexpectedly changed the rules of survival for two local mistletoe species. Researchers found that the heavy winter rains caused one mistletoe to produce fewer flowers, while the other flourished, producing more flowers and fruit. This difference had a ripple effect on the local wildlife. The mistletoe that struggled saw a complete change in its animal visitors, shifting from birds to more insects and small mammals. The mistletoe that thrived attracted a greater variety of animal species after the rain. The study shows that even in harsh environments, a single weather event can create winners and losers, reshaping the delicate relationships between plants and animals.
