The humble sea campion flower can show us how species adapt

Ancestral variation guides future environmental adaptations

The speed of environmental change is very challenging for wild organisms. When exposed to a new environment individual plants and animals can potentially adjust their biology to better cope with new pressures they are exposed to—this is known as phenotypic plasticity.

Plasticity is likely to be important in the early stages of colonizing new places or when exposed to in the environment. New research published in Nature Ecology & Evolution, shows that early plasticity can influence the ability to subsequently evolve to conquer new habitats.

Sea campion, a coastal wildflower from the U.K. and Ireland has adapted to toxic, zinc rich industrial-era mining waste which kills most other . The zinc-tolerant plants have evolved from zinc-sensitive, coastal populations separately in , several times.

To understand the role of plasticity in rapid adaptation, a team of researchers lead by Bangor University conducted experiments on sea campion.

As zinc-tolerance has evolved several times, this gave the researchers the opportunity to investigate whether ancestral plasticity made it more likely that the same would be used by different populations that were exposed to the same environment.

By exposing the tolerant and sensitive plants to both benign and zinc contaminated environments and measuring changes in the expression of genes in the plant's roots, the researchers were able to see how plasticity in the coastal ancestors has paved the way for adaptation to take place very quickly.

"Sea campion usually grow on cliffs and shingle beaches, but mining opened up a new niche for them that other plants weren't able to exploit. Our research has shown that some of the beneficial plasticity in the coastal plants has helped the mine plants to adapt so quickly," says Dr. Alex Papadopulos, senior lecturer in biology.

"Remarkably, if a gene responds to the new environment in a beneficial way in the ancestral plants, it is much more likely that that gene will be reused in all of the lineages that are independently adapting to the new environment. Phenotypic plasticity may make it more likely that there would be the same evolutionary outcome if the tape of life were replayed. If we understand the plastic responses that species have to , we may be better equipped to predict the impacts of climate change on biodiversity."
