However, the different marine locations demonstrate differences in the relative abundance of RNR classes, and only the Arctic and the Sargasso Sea contain class Ib genes.
The fact that the Gibraltar Strait and the Almeria-Oran front may or not act as barrier to gene flow for different marine pelagic species has been attributed to differences in life-history traits (e.g. dispersal capacity [ 2]) and for other marine fish species due to the existence of distinct past demographical events (e.g. bottlenecks [ 7]).
Scientists from around the world have been involved in 17 different marine projects that will inform the census, a 10-year project that will provide a snapshot of life in the world's oceans.
For instance, the leaders of the Tagging of Pacific Predators project, a 10-year tracking study of 23 different marine species, created a Web site broadcasting the movements of their subjects in real time (or close to it).
Its tanks are stocked according to different marine zones, with specimens from the Indian Ocean, European rivers and lakes, the Great Barrier Reef, mangrove swamps, rainforests, and other areas.
"Every country has different marine regulations for different things, " says Mr Bursiewicz.
These contaminants enter and accumulate in different marine niches, hence deeply compromising their quality and integrity.
Choice experiments are used in order to determine how fisher participation rates change under different marine PES programme designs.
Many marine organisms use sounds to navigate, forage and communicate, while different marine habitats often have their own acoustical characteristics.
The effect of single environmental and human variables considered in the analyses was different for different marine groups.
How ocean sounds affect different marine species "is something we are only just beginning to understand," says Greg Early, associate scientist with the Edgerton Research Lab.
