Amphidromous fish—which migrate between freshwater streams and the sea—can move between habitats thanks to ocean currents. Since island streams are generally small and vulnerable to human impact, ...

Nepal, largely covered by the Himalayan mountains, hosts indigenous populations with distinct linguistic, cultural, and genetic characteristics. Among these populations, the Raute, Nepal’s last ...

ISLAND LIFE is famously idyllic, but it’s long been known that islanders tend to experience disproportionately high rates of some rare genetically transmitted diseases. Faroe islanders, for example, ...

A new genetic study has revealed that the people of Deep Mani, who inhabit one of the remotest regions of mainland Greece, represent one of the most genetically distinctive populations in Europe, ...

Reproductive isolation in Drosophila involves a suite of genetic mechanisms that operate at sequential stages to prevent gene flow and facilitate speciation. Premating barriers arise through ...

New research in Indonesia shows that small islands, often considered extinction hotspots, can act as crucial refuges for rare mammals like the anoa and babirusa, which face severe threats from ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...
