Climate Change Remains a Threat to Corals
Hopes that coral reefs might be able to survive, and recover from, bleaching caused by climate change have grown dimmer for certain coral species. It was previously thought that corals may be able to take up stress-tolerant algae to provide critical nutrients, but they cannot do this for any length of time. -
Several species of Killer Whale, scientist say
It has long been thought that there were several types of killer whales. Now scientists are recommending that at least three be reclassified as separate species. -
Barnacle Dinner in the Galapagos
The barnacle, a key thread in the marine food web, was thought to be missing along rocky coasts dominated by upwellings. Now a research team headed by Brown University marine ecologist Jon Witman has found the opposite to be true: Barnacle populations thrive in vertical upwelling zones in moderately deep waters in the Galapagos Islands. Working [...] -
Red Grouper create home for many animals
Researchers from Florida State University have found that Red Grouper (Epinephelus morio) dig out and maintain complex structures at the bottom of the sea. They remove sand, exposing hard rocks that are crucial to corals and sponges and the animals that rely on them. The work demonstrates that Red Groupers modify their environment, much as [...] -
Minke Whales Should Not be Culled
A new genetic analysis of Antarctic minke whales concludes that population of these smaller baleen whales have not increased as a result of the intensive hunting of other larger whales – countering arguments by advocates of commercial whaling who want to “cull” minke whales. Antarctic minke whales are among the few species of baleen whales not [...] -
King Crab Family Grows
PhD student Sally Hall has formally described four new species of king crab, all from the deep sea.javascript:void(0)The new species are Paralomis nivosa from the Philippines, P. makarovi from the Bering Sea, P. alcockiana from South Carolina, and Lithodes galapagensis from the Galapagos archipelago – the first and only king crab species yet recorded from [...] -
Tags reveal Great White Sharks’ Beat
A tracking study of white sharks in the northeastern Pacific Ocean shows they follow a rigid migration route across the sea, returning to precisely the same spot on California coast each time they come back. Over tens of thousands of years, this behavior has made the population in the northeastern Pacific genetically distinct from other [...] -
Creature of the Month: Plumose Anemone
Plumose anemones (Metridium senile) occur in large numbers in good diving areas in temperate waters. They comprise a tall, smooth column topped with a crown of feathery tentacles. When they contact they look like swirly blobs, as can be seen in our photograph. Individuals may be white, orange, green or blue in colour. They grow up [...] -
Killer Whales Die without Chinook Salmon
When you mention killer whales, the image of one ambushing a terrified seal often springs to mind. But there are populations of killer whales who live exclusively on fish. And not on just any fish: they are very specialised in which fish they will eat. According to research published in Biology Letters, two populations [...] -
Rare Algae Saves Caribbean Coral
A rare opportunity has allowed a team of scientists to evaluate corals–and the essential, photosynthetic algae that live inside their cells–before, during, and after a period in 2005 when global warming caused sea-surface temperatures in the Caribbean to rise. The team, led by Penn State biologist Todd LaJeunesse, found that a rare species of algae that [...]
