The effects of ocean acidification on living marine resources present serious challenges for managers of these resources. An understanding of the ecosystem consequences of ocean acidification is required to assess tradeoffs among ecosystem components (e.g. fishery yield, protected species conservation, sensitive habitat) and adaptations to this perturbation. We used a ...

Linking Rising pCO2 and Temperature to the Larval Development and Physiology of the American Lobster (Homarus americanus)

Few studies have evaluated the joint effects of elevated temperature and pCO2 on marine organisms. In this study we investigated the interactive effects of Intergovernmental Panel on Clinate Change predicted temperature and pCO2 for the end of the 21st century on key aspects of larval developm,ent of the American lobster, Homarus americanus, an otherwise well-studied, ...

Marine calcifiers exhibit mixed responses to CO2-induced ocean acidification

Eighteen marine species exposed to ocean acidification conditions for 60 days exhibited a wide range of responses. Ten of the 18 species were affected negatively with lower rates of net calcification and, in some cases, net loss of shell. Those species included temperate corals, pencil urchins, hard clams, conchs, serpulid ...

Deformities in larvae and juvenile European lobster (Homarus gammarus) exposed to lower pH at two different temperatures

The ongoing warming and acidification of the world's oceans are expected to influence the marine ecosystems, including benthic marine resources. Ocean acidification may especially have an impact on calcifying organisms, and the European lobster (Homarus gammarus) is among those species at risk. A project was initiated in 2011 aiming to ...

Creation of a Gilded Trap by the High Economic Value of the Maine Lobster Fishery

Unsustainable fishing simplifies food chains and, as with aquaculture, can result in reliance on a few economically valuable species. This lack of diversity may increase risks of ecological and economic disruptions. Centuries of intense fishing have extirpated most apex predators in the Gulf of Maine (United States and Canada), effectively ...

Ocean Acidification Decreases Growth and Development in American Lobster (Homarus americanus) Larvae

  • Posted on: Tue, 03/29/2016 - 17:03
  • By: petert

Ocean acidification resulting from the global increase in atmospheric CO2 concentration is emerging as a threat to marine species, including crustaceans. Fisheries involving the American lobster (Homarus americanus) are economically important in eastern Canada and United States. Based on ocean pH levels predicted for 2100, this study examined the effects ...

Ocean and coastal acidification off New England and Nova Scotia

  • Posted on: Sun, 02/21/2016 - 15:47
  • By: petert

This Oceanography paper discusses ocean and coastal acidification processes specific to New England coastal and Nova Scotia shelf waters and reviews current understanding of the biological consequences most relevant to the region. It also identifies key research and monitoring needs to be addressed and highlight existing capacities that should be ...
