Cal Poly Humboldt theses and projects
Ocean acidification (OA) is often demonstrated to have negative effects on marine organisms, but less is known about whether marine organisms can mediate OA effects. I examined relationships between surfgrass (Phyllospadix spp.), a foundation species and tidepool biodiversity, and its ability to mediate fluctuations in pH and dissolved oxygen (OA; DO) which are stressors in tidepools. I surveyed tidepools in northern California, where I quantified biodiversity, pH, and DO, and related those variables to surfgrass abundance. Laboratory and field experiments manipulating CO2 and surfgrass presence were done to examine surfgrass effects on day/night pH and DO fluctuations …
