Detailed study of a Greenland glacier’s flow rate reveals the impact of environmental conditions.

Predicting and mitigating the effects of climate change while preserving biodiversity is a top priority for both scientists and policymakers. As climate change intensifies, leading to more frequent and severe droughts, understanding the impact on natural ecosystems has become increasingly important. One of the main challenges is forecasting changes in species richness due to shifts in precipitation patterns.  A new study, carried out by the HUN-REN Centre for Ecological Research in Hungary, examines the intricate connections between long-term changes in rainfall, extreme drought conditions, the biomass of dominant plant species, and plant species diversity in a dryland ecosystem. Published in the Journal of Ecology, the research reveals that increased dryness leads to a reduction in plant species diversity in drylands and uncovers the mechanisms through which rising aridity contributes to biodiversity loss in these fragile ecosystems.
