**Summary:**
A new study published in “Nature Ecology & Evolution” reveals a universal pattern in how species are organized across the globe, regardless of biogeographical region or taxonomic group. Researchers analyzed over 30,000 species and found that biodiversity is structured in layers, like an onion, with core hotspots of unique and endemic species gradually transitioning to outer layers with fewer species and more generalists. Temperature and rainfall are key factors determining these layers. The discovery could help conservation efforts by identifying critical habitats and understanding how species will respond to climate change. While the study is globally significant, experts stress the need for more region-specific research, particularly in underrepresented biodiversity-rich areas like parts of India, to refine and strengthen the findings.

**Indian Perspective: Global Biodiversity Organizes in Universal Layers, Study Reveals**
*Srinagar, August 18, 2025* – A groundbreaking study reveals that Earth’s biodiversity isn’t as chaotic as previously thought, but follows a universal pattern of layered organization, regardless of continent or species. The research, published in “Nature Ecology & Evolution,” analyzed over 30,000 species worldwide, including birds, mammals, insects, and plants.
Researchers discovered that biodiversity is arranged like an onion: core regions are rich in unique, endemic species, transitioning to outer layers with fewer species and more common, widespread ones. Temperature and rainfall are key factors in determining these layers.
“The study provides a rare, large-scale, data-backed confirmation of a general rule in biogeography,” says Irfan Rashid, assistant professor at the University of Kashmir’s Department of Botany.
Indian experts see significant implications for conservation efforts. Amit Chawla, Principal Scientist at CSIR-IHBT, highlights the potential to focus on critical habitats and corridors beyond traditional protected areas. “We need to look at how changes in rainfall or temperature are affecting biodiversity along mountain slopes,” Chawla added, referencing the Indian Himalayas as a key area of concern due to rising temperatures and shifting rainfall patterns. Asif Bashir Shikari, professor at Sher-e-Kashmir University, agrees that this offers a useful lens to understand the big picture.
However, researchers also note the study’s limitations, particularly a lack of data from some biodiversity-rich regions, including parts of India. Chawla emphasized the need for more region-specific research to complement global findings and tailor conservation strategies. Understanding how species spread outward from regional hotspots and how climate acts as filter is vital for making informed decisions on what to protect and where, especially as the world grapples with climate uncertainty.
