PLOS Field surveys and satellites complement each other when studying remote penguin populations, according to research published June 25 in the open access journal PLOS ONE by André Ancel from the CNRS at Strasbourg and colleagues. Penguins residing on Antarctica's ice sheets must face moving, breaking, and shifting ice. Accurate monitoring of population trends is critical to understanding the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical...

redOrbit Staff & Wire Reports - Your Universe Online The development of the sea-ice ecosystem in the circum-Antarctic Southern Ocean may have triggered further adaptation and evolution of larger organisms such as baleen whales and penguins, according to a new study published Thursday in the journal Science. The area´s ecosystem can be traced back to the emergence of the Antarctic ice sheets some 33.6 million years ago and plays an important role in global marine food webs and...

Proposal follows first continent-wide survey of Antarctic biogeography An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

Scientists say the Antarctic Peninsula's most fearsome land predator is a reddish bug called the Rhagidia mite. Although the continent is best known for penguins, seals and whales, the tiny mite is considered it's top predator. Now researchers are stepping up their study of these miniscule creatures in Antarctica for possible early warnings about how climate change may disrupt life around the planet in coming decades. Pete Convey, a biologist at the British Antarctic Survey, said Antarctica...

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...

The Neotropic ecozone is one of Earth's eight ecosystems. This ecozone is also known as the Neotropical ecozone. It is made up of South and Central America, the Mexican lowlands, Caribbean Islands, and southern Florida. The southernmost part of South America is part of the Antarctic ecosystem. Many of the regions included in the Neotropic share the same diversity among plant and animal life. The flora and fauna of the Neotropic are unique and distinct from the Nearctic (which includes most of...

Antarctica is one of Earth's eight ecozones. The Antarctic ecozone includes Antarctica and several island groups in the southern Atlantic and Indian Oceans. The island groups included in this ecosystem include South Georgia and the South Sandwich Islands, South Orkney Islands, South Shetland Islands, Bouvet Island, the Crozet Islands, Prince Edward Islands, Heard Island, the Kerguelen Islands, and the McDonald Islands. These islands have milder climates than Antarctica and support a greater...
