Dorothy Horn, a Ph.D. candidate in PSU's Earth, Environment and Society program, examined the effects of exposure to microfibers on adult mortality, reproductive output and embryonic development of the sand crab, a dominant organism on sandy beaches from British Columbia to Baja California, Mexico.

"When pollutants affect sand crabs, it's also affecting most organisms around it in that ecosystem," Horn said. "We don't eat them, but they're a bright blinking light for 'There's a problem in this area.'"
