A global study published in Nature Ecology & Evolution reveals a universal pattern in species distribution across biogeographical regions, offering new insights into global biodiversity organization.
Key Findings of the Study:
- Onion-like Structure: Dense core zones with high richness and endemicity, gradually transitioning through moderate diversity layers to species-poor outer zones dominated by generalists (subsets of inner species).
- Universal Pattern: Despite regional differences (e.g., South America vs. Africa), species in diverse taxa (birds, mammals, amphibians) follow a common biogeographical structure.
- Climatic Determinants: Temperature and rainfall predict species distribution with 98% accuracy, showing the strong role of environmental filters like climate and elevation.
Implications for Conservation:
- Redefining Focus: Move beyond administrative protected areas towards ecological corridors and biodiversity hubs, crucial for climate-sensitive regions like the Himalayas.
- Addressing Data Gaps: Underrepresentation of tropical regions, Global South, and certain taxa (e.g., dragonflies, trees) calls for more region-specific studies in India.
- Climate-Responsive Strategy: Monitoring rainfall and temperature shifts can support adaptive conservation planning.
