NEW SCIENTIST 09/09/16 Global treaty set to halt invasive species ravaging our oceans. ImageBROKER/REX/Shutterstock By Andy Coghlan At last, the game may be up for marine invaders that hitch free rides across the globe in ships’ ballast water.
A global convention to stop this happening was formally triggered on 8 September, more than two decades after it was proposed, and will officially come into force a year from then. The convention will compel many of the world’s 70,000 or so registered cargo ships to install equipment guaranteed to kill off any aquatic creatures in seawater taken on board to maintain stability. Advertisement The arrival of the comb jelly (pictured top) in the Black, Azov and Caspian seas from its home on the east coast of North America caused the catastrophic collapse of fisheries in the 1990s.
Crossing in the opposite direction as larvae, zebra mussels (pictured below) have caused an estimated $1 billion worth of damage between 1989 and 2000 in the US Great Lakes by blocking water intake pipes.

An ocean heavily populated by invasive species of algae, jellyfish, crabs and shellfish may be the future if ocean acidification continues.
“A rapidly growing body of research indicates that ocean acidification will severely disrupt marine ecosystems, since it alters the balance of success between competing organisms. Ocean acidification can impact a wide range of processes across marine taxa, including photosynthesis, acid-base homeostasis, calcification and behavior,” Plymouth Univ. researchers write in Research and Reports in Biodiversity Studies. However, “the traits that help many invasive organisms succeed, such as wider physiological tolerance and reproductive advantage in the face of multiple stressors, are traits that look set to help them in an acidifying ocean.”
The study was prompted when Prof. Jason Hall-Spencer, the study’s lead author, witnessed the marine life thriving near volcanic sites in the Mediterranean.

In 1989, the oil tanker Exxon Valdez ran aground in Alaska, spilling millions of liters of crude oil and killing hundreds of thousands of marine mammals and birds.
It was one of the worst environmental disasters in history. Alaska’s coast has, fortunately, not seen a repeat event since. But every day, Alaska’s ecosystem is endangered by oil tankers—though in a far more subtle way. Before they travel the world’s oceans, oil tankers and other large ships that are not carrying cargo will suck up as much as tens of millions of liters of water into tanks to help maintain balance and stability. When a tanker reaches port in Alaska and is preparing to take on oil, it will dump this water into the sea. The main problem with ballast water is that ships are often near the shore when they fill their tanks, and are near the shore again when they discharge the water at their destination, which might be thousands of kilometers away. But that will only happen if progress continues.

1Scottish Association for Marine Science, Scottish Marine Institute, Oban, Argyll, 2Alyth, Perthshire, 3Scottish Association for Marine Science Research Services Limited, Scottish Marine Institute, Oban, Argyll, 4Firth of Clyde Forum, Glasgow, UK Abstract: Nonindigenous species (NIS) are those that have been intentionally or unintentionally introduced outside of their native range as a consequence of human activity.
If these species then threaten indigenous species and biodiversity, and/or cause economic damage, they are referred to as “invasive.” Biological invasions are not only one of the greatest threats to indigenous marine biodiversity, but they can also cause massive economic and ecological damage. Their presence could also lead to a water body failing to achieve good environmental status under the forthcoming EU Marine Strategy Framework Directive.

PLOS 15/04/15 Classification of Non-Indigenous Species Based on Their Impacts: Considerations for Application in Marine Management. Abstract Assessment of the ecological and economic/societal impacts of the introduction of non-indigenous species (NIS) is one of the primary focus areas of bioinvasion science in terrestrial and aquatic environments, and is considered essential to management.
A classification system of NIS, based on the magnitude of their environmental impacts, was recently proposed to assist management. Here, we consider the potential application of this classification scheme to the marine environment, and offer a complementary framework focussing on value sets in order to explicitly address marine management concerns. Since existing data on marine NIS impacts are scarce and successful marine removals are rare, we propose that management of marine NIS adopt a precautionary approach, which not only would emphasise preventing new incursions through pre-border and at-border controls but also should influence the categorisation of impacts.

Forest Carbon Sequestration Converting land for biofuel production can cause biodiversity impacts in the short-term, but such conversion also aects the future resilience of natural ecosystems.
