Rapid increases in ocean acidity puts crustose coralline algae in a growth predicament, research by a Smithsonian marine scientist shows.
Estimating shark populations on degraded Caribbean reefs is complicated, especially when there few around. A pioneering member of the O’Dea lab has developed a technique to estimate shark populations — both past and present — using their microscopic skin scales
