Hidden values of open ocean: Eastern Tropical Pacific provides 'ecosystem services' worth at least $17 million

Hidden values of open ocean: Eastern Tropical Pacific provides 'ecosystem services' worth at least $17 million | Marine Conservation Research | Scoop.it
A team of scientists has for the first time attached a dollar value to several of the leading 'ecosystem services' -- or natural benefits -- provided by the Eastern Tropical Pacific Ocean, an immense region stretching west from the west coasts of North and South America.

Manta rays are local commuters, not long-distance travelers, study finds: Study has important implications for the threatened species' conservation

Manta rays are local commuters, not long-distance travelers, study finds: Study has important implications for the threatened species' conservation | Marine Conservation Research | Scoop.it
Oceanic manta rays -- often thought to take epic migrations -- might actually be homebodies, according to a new study. A research team studied satellite-tracked manta rays to shed light on the lives of these mysterious ocean giants.

Microplastic particles threaten fish larvae

Microplastic particles threaten fish larvae | Marine Conservation Research | Scoop.it
Researchers have found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. The researchers discovered that larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.
Gaye Rosier's insight:
The frightening consequence of our plastic pollution.

Nanoplastics negatively affect aquatic animals

Nanoplastics negatively affect aquatic animals | Marine Conservation Research | Scoop.it
Plastic accounts for nearly eighty per cent of all waste found in our oceans, gradually breaking down into smaller and smaller particles. New research investigates how nanosized plastic particles affect aquatic animals in different parts of the food chain.

Antarctic bryozoans give hints of environmental changes in oceans

Antarctic bryozoans give hints of environmental changes in oceans | Marine Conservation Research | Scoop.it
Antarctic regions are natural laboratories to study biodiversity and the impact of climate change. In Antarctica, some marine ecosystems are particularly vulnerable to the ocean acidification due to an excess of carbon dioxide released into the atmosphere. Studying the Antarctic bryozoans, marine invertebrates that live in colonies and make mineralized skeletons, can create new views to understand the effects of global ocean acidification.

Ocean currents push phytoplankton, and pollution, around the globe faster than thought

Ocean currents push phytoplankton, and pollution, around the globe faster than thought | Marine Conservation Research | Scoop.it
Ocean currents can carry objects to almost any place on the globe in less than a decade, faster than previously thought. While good for microorganisms such as phytoplankton that are essential to the marine food web, it also means that plastic debris, radioactive particles and virtually any kind of litter can quickly become a problem in areas far from where they originated.
Gaye Rosier's insight:
The oceans are all one and the whole world has to agree a plan to save them - and ourselves!

New imaging technique reveals vulnerability of coral reefs

New imaging technique reveals vulnerability of coral reefs | Marine Conservation Research | Scoop.it
Researchers have created a novel method using micro-computed tomography scans to expose how bioerosion and secondary accretion of corals -- critical processes for reef sustainability -- respond to varying environmental conditions, including changing ocean acidity.
Gaye Rosier's insight:
Useful research sheds light on how reefs are coping, or not, with ocean acidification.

Gaye Rosier's insight:
All plastics should be made this way. If it costs more, we'll learn to use less. Many island nations are heavily dependent on nutrition from the sea whilst the "civilized " West uses the sea as a garbage dump and chokes the life out of it!

New research helps solve the riddle of the ocean carbon conundrum: About a quarter of the carbon dioxide we release each year ends up in the ocean, but how it happens is still not fully understood

New research helps solve the riddle of the ocean carbon conundrum: About a quarter of the carbon dioxide we release each year ends up in the ocean, but how it happens is still not fully understood | Marine Conservation Research | Scoop.it
Initially, the fact that the oceans are absorbing a significant amount of the carbon dioxide we pump into the atmosphere by burning biomass and fossil fuels would appear to be a good thing. However, as more carbon dioxide dissolves into the oceans, it changes the pH of the seawater (a process called ocean acidification), making it difficult for some marine life to survive.
Gaye Rosier's insight:
The seas around Europe absorb 24 million tonnes of carbon each year!

Bachelor's paradise: Female turtles outnumbering males due to warming temps: Climate change posing long-term stability challenges for turtles

Bachelor's paradise: Female turtles outnumbering males due to warming temps: Climate change posing long-term stability challenges for turtles | Marine Conservation Research | Scoop.it
Rising global temperatures may skew gender imbalance among the marine turtle population, according to new research. The sex of marine hatchlings is influenced by incubating temperatures, and warmer temperatures produce a higher number of female hatchlings.
Gaye Rosier's insight:

This population skew due to climate change could impact turtle survival.

'Coral zombies' may spell doom for coral reefs around world

'Coral zombies' may spell doom for coral reefs around world | Marine Conservation Research | Scoop.it
Scientists have known for a while that coral reefs around the world are dying, and in a worst-case scenario they were counting on large, healthy-looking corals to repopulate. But a new study shows that these seemingly healthy colonies are 'Coral Zombies' with no reproductive ability, which makes them useless in a recovery effort.

Seagrass genome study to boost ecological insight in marine ecosystems

Seagrass genome study to boost ecological insight in marine ecosystems | Marine Conservation Research | Scoop.it
Seagrasses not only sustain harvestable fish and invertebrates like lobsters, shrimp and crabs; they also play a part in controlling erosion effects and capturing carbon dioxide.
Gaye Rosier's insight:

Seagrasses provide the foundation of highly productive ecosystems present along the coasts of all continents except Antarctica, where they rival tropical rain forests and coral reefs in ecosystem services.
