A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity. Their study is published this week in the peer-reviewed journal Annals of the New York Academy of Sciences. "Although  Antarctica is still the most pristine environment on Earth, its marine ecosystems are being degraded through the introduction of...

By studying the tolerance of marine invertebrates to a wide range of temperature and pressure, scientists are beginning to understand how shallow-water species could have colonized the ocean depths. Scientists believe that climate changes at various at various times during Earth's history caused extinctions of creatures living at bathyal (1,000"“4,000 meters) and abyssal (>4,000 m) depths. These extinctions were apparently followed by re-colonization of the deep sea by shallow-water...

Invasions of voracious predatory crabs due to global warming could threaten the unique continental-shelf ecosystems of Antarctica, according to newly published findings. "King crabs are ecologically important predators and form the basis of economically significant commercial fisheries," said Dr Sven Thatje, an evolutionary ecologist at the University of Southampton's School of Ocean and Earth Science (SOES), which is based at the National Oceanography Centre in Southampton. Thatje and...

A study of animals visible to the naked eye and living in and on the seabed "“ the 'macrobenthos' "“ of the Straits of Magellan and Drake Passage will help scientists understand the biodiversity, biogeography and ecology of the Magellanic region. "The biodiversity data are from my very first oceanographic cruise with the Chilean Navy in the Magellanic region in 1997, as an early undergraduate," said Dr Sven Thatje of the University of Southampton's School of Ocean and Earth...

An army of voracious giant crabs is on the brink of invading the shallow seas off Antarctica, where an array of unique, almost prehistoric sealife has evolved for millions of years without any predators. Scientists warned yesterday that global warming was raising the temperature of the seas, allowing the crabs to creep ever higher up the slope leading to the continental shelf. These waters, whose temperature is about freezing point, are home to fish with anti-freeze proteins in...

Frozen in time"¦ frozen in place"¦ frozen solid"¦ All of these phrases have been used to describe Antarctica, and yet they all belie the truth about this southerly point on the globe. Although the area is covered in ice and bears witness to some of the most extreme cold on the planet, this ecosystem is dynamic, not static, and change here has always been dramatic and intense. A report published in the March issue of Ecology argues that the extreme cold and environmental...

The ice ages made massive changes to the Earth's landscape The ice ages made massive changes to the Earth's landscape. But what was happening below the ice in the oceans? Research by marine scientists reveals that it was a time of mass destruction as whole communities of animals were wiped out by ice sheets scouring the sea floor. In the past it has been thought that these ecosystems somehow dodged extinction by recolonising from nearby habitats that escaped obliteration. But researchers at...

  • A 'bachelor seal'; a young male seal which is prevented from mating by its herd's older males (mated bulls defending their territory).
This comes from the Russian word for 'bachelors.'
