Temperature and ecology: In Chile, rival barnacles keep competition cool

A lot of research shows that temperature can strongly influence species interactions and sometimes shape the appearance and functioning of biological communities. That’s why a newly published finding that changes in temperature did not alter the competitive balance of power between two rival species of Chilean barnacles is an ecological surprise.

PROVIDENCE, R.I. [Brown University] — Here are two facts that make the lowly barnacle important: They are popular models for ecology research, and they are very sensitive to temperature. Given that, the authors of a new study about a bellwether community of two barnacle species in Chile figured they might see clear effects on competition between these two species if they experimentally changed temperature. In the context of climate change, such an experiment could yield profound new insights into the biological future of a major coastline that is prized for its ecological, aesthetic, and economic values.
