Spatial differentiation of marine eutrophication damage indicators based on species density

“Spatial differentiation of marine eutrophication damage indicators based on species density” was recently published in Ecological Indicators, co-authored by Nereus Alumnus Miranda Jones (UNEP-WCMC) and Nereus Director of Science William Cheung. The paper looks at developing an index to assess eutrophication effects on marine ecosystems and introducing an ecosystem response indicator to nitrogen loadings to coastal waters.

Sustainable management of the high seas could recoup fish stock losses due to climate change

Closing the high seas to fishing could increase fish catches in coastal waters by 10%, compensating for expected losses due to climate change, finds a new Nippon Foundation-Nereus Program study published in Fish and Fisheries.

The high seas are those areas of the ocean outside the jurisdiction of countries; the high seas cover nearly two thirds of the ocean’s surface. These results could be seen by 2050 relative to 2000 and cooperatively managing the high seas fisheries would have similar effects.

International Marine Conservation Congress (IMCC4)

The International Marine Conservation Congress (IMCC) took place from July 30th to August 3rd in St. John’s, Newfoundland, Canada. The congress brings together marine conservation professionals and students in order to “develop new and powerful tools to further marine conservation science and policy”. Under the theme of “Making Marine Science Matter”, this year’s conference dealt with strategies to influence policy-makers and stakeholders, and was divided among several topics of interest, including marine food security, ocean science technology, and marine policy.

Where do we go from here? Building confidence in climate change impact projection models

Climate change is expected to have major impacts on the ocean, the species that live there, and the people who rely it for their food and livelihood. Since the beginning of the 20th century, CO2 emissions from human activities have altered physical and chemical properties of the ocean. The ocean has become warmer and, in some areas, less oxygenated, which has caused changes in the productivity and distribution of marine species.
