Effects of ocean acidification on growth rate, calcified tissue, and behavior of the juvenile ochre sea star, Pisaster ochraceus

Creator:

Britsch, Melissa L.

Abstract:

Anthropogenically-induced increases in the acidity of the ocean have the potential to seriously harm marine calcifying organisms by decreasing the availability of carbonate (CO32−) used to make shells. I tested the effects of lowered pH on juvenile Pisaster ochraceus, an intertidal sea star and keystone predator in the eastern Pacific...

Ocean Acidification Carryover Effects from Oyster Broodstock to Larvae

Creator:

Klein, Victoria G.

Abstract:

Atmospheric carbon dioxide has increased by approximately 40% since preindustrial times from 280 ppm (parts per million) to 400 ppm. The rise in Pco₂ is causing the ocean to become more acidic due to the uptake of carbon dioxide by the water, termed “ocean acidification”. As the Pco₂ in the...
