Genetic evidence reveals how goosegrass colonized a newly formed volcanic island

Opportunities to directly observe how life colonizes newly formed land and how ecosystems subsequently develop are exceedingly rare.

In a study published in the Journal of Plant Research, researchers at University of Tsukuba used genetic analyses to investigate the origin of Eleusine indica, a grass species found on Nishinoshima, an active volcanic island in the northwestern Pacific south of mainland Japan.

Having newly emerged, the island offers a unique natural laboratory for understanding the earliest stages of biological colonization and ecosystem development.
