How do barnacles survive environmental changes?

Barnacles, often found on seashores, attach to various surfaces and develop into adults. They have adapted to survive harsh conditions by building protective plates. Research from Brown University, funded by the NSF, highlights the role of the Mpi protein in helping barnacles endure environmental changes. Different Mpi enzyme forms are suited to varying stress levels, aiding barnacle survival. This research could inform studies on honeybee adaptation to climate change and agricultural productivity.

What adaptations do barnacles have that allow them to thrive in fluctuating environments?

In what ways could the research on barnacle genes be applied to other species?
