Ce se află în „seifurile” ascunse ale Pământului? Descoperirea tulburătoare a oamenilor de știință • Newsweek România

Scientists have discovered that the soil beneath our feet contains a vast reserve of seeds, averaging over 5,000 seeds per square meter globally. This natural seed bank plays a crucial role in ecosystem recovery after disturbances. However, the study reveals a concerning trend: high seed density does not always correlate with species diversity. Tropical ecosystems show rich species in seed banks but lower seed density, while agricultural lands have high density but reduced diversity. The findings suggest that human activities are impacting not only surface vegetation but also the hidden seed reserves in the soil, raising concerns about nature's ability to recover lost biodiversity.
