A volcano in Iceland helps scientists perceive how life types unfold to new habitats

How life types unfold to new habitats is a course of that’s not properly understood by ecologists.

A University of Arizona0led study of the Fagradalsfjall volcano in Iceland helps paint a greater image.

The workforce was capable of finding DNA from micro organism generally inside hours of lava solidifying into rock.

Then they might accumulate samples over the next days and weeks to see how a lot the micro organism would develop over time. They monitored the outcomes from three totally different eruptions of the identical volcano.

The examine discovered that a lot of the primary organisms to start out populating the brand new rock had been micro organism that doubtless got here from soil and rain.

Study writer Nathan Hadland with UA says one of many key findings is that the way in which micro organism colonized the areas was predictable.

“Because there was such a constant nature throughout all the pattern websites we studied, that lends itself into this extra deterministic view that, there’s very constant species which might be in a position to survive these circumstances,” Hadland said.

Hadlandsays this under researched area of ecology could help scientists understand how life spread around earth in the first place.

“A significant thought is that lava circulate fields had been one of many first areas for all times to colonize land if it transitioned out of hydrothermal techniques or the ocean, relying on the place it originated. And in order that’s type of one of many large implications of the examine.” he stated.

The examine was revealed within the journal Nature Communications Biology.
