Clavelina oblonga, an invasive marine fouling species, not only reduces diversity in communities it invades, it also interferes in their recovery following natural disasters - a process known as "succession."
How does whale watching affect whale behavior? Who watches whales in Panama's Las Perlas Archipelago? Researchers from STRI and ASU hope to recommend innovative data-based conservation strategies.
New data on the growth rates of coral reefs shows there is still a window of opportunity to save them from eroding by mid-century--but time is running out.
A chemical that the New South Wales government has recently partially banned in firefighting has been found in the pups of endangered Australian sea lions and in Australian fur seals. The finding represents another possible blow to Australian sea lions' survival. Hookworm and tuberculosis already threaten their small and diminishing population, which has fallen by more than 60 percent over four decades.
Numbers of two Mediterranean turtle species have risen in the last three decades - but in Cyprus the recoveries are happening at different rates, new research shows.
Thousands of sharks have been illegally caught in a Marine Protected Area (MPA) in the Indian Ocean, new research shows.
A Flinders University researcher has finally fathomed why large numbers of killer whales gather at a single main location off the Western Australian southern coastline every summer. In a new paper published in Deep Sea Research, physical oceanographer Associate Professor Jochen Kampf describes the conditions which have produced this ecological natural wonder of orcas migrating to the continental slope near Bremer Bay in the western Great Australian Bight from late austral spring to early autumn (January-April).
Coral bleaching, which is becoming stronger and more frequent due to heat stress, has already wiped out corals at many locations globally. With the help of a microbiome-targeting strategy developed by an international team led by GEOMAR Helmholtz Centre for Ocean Research Kiel, it could become feasible to help protect corals from heat stress.
A new study from McGill University suggests that some Icelandic killer whales have very high concentrations of PCBs (polychlorinated biphenyls) in their blubber. But it seems that other orcas from the same population have levels of PCBs that are much lower. It mainly depends on what they eat.
New research from the University of Nebraska-Lincoln, Yale University and Stanford University suggests that temperature can largely explain why the greatest variety of aquatic life resides in the tropics -- but also why it has not always and, amid record-fast global warming, soon may not again.
