The epic ocean-spanning journeys of the gigantic leatherback turtle in the South Atlantic have been revealed for the first time thanks to groundbreaking research using satellite tracking.
Experts at the Centre for Ecology and Conservation (Cornwall) at the University of Exeter led a five-year study to find out more about these increasingly rare creatures and inform conservation efforts. (more…)
ANN ARBOR, Mich.—There’s a whale of a new display at the University of Michigan Exhibit Museum of Natural History, a leviathan that represents a scientific saga of equally grand proportions. (more…)
A novel project using cameras mounted on unmanned aircraft flying over the Arctic is serving double duty by assessing the characteristics of declining sea ice and using the same aerial photos to pinpoint seals that have hauled up on ice floes.
The project is the first to use aircraft to monitor ice and seals in remote areas without putting pilots and observers at risk, said Elizabeth Weatherhead of the University of Colorado at Boulder, who is leading the study team. Weatherhead is a senior scientist at the Cooperative Institute for Research in Environmental Sciences, a joint venture of CU-Boulder and the National Oceanic and Atmospheric Administration. (more…)
The fears connected with shark attacks are stronger in the world today than those related to much more dangerous predators – crocodiles. However, crocodiles pose a greater threat to humans than sharks do.
A crocodile snatched Hendrik Coetzee, a South African guide, 35, from his kayak while he led an American expedition into the heart of Congo last week. Two American tourists could only watch the scene in horror as the guide was killed and eaten by the predator. They paddled to safety unharmed. Coetzee’s body has not been recovered.
Stories about croc attacks are just as terrible as they are hopeless. Experts say that it is possible to stay to fight off a shark, but it is much more difficult or even impossible to rescue themselves from an attacking croc. (more…)
ANN ARBOR, Mich. — A wave of reptile extinctions on the Greek islands over the past 15,000 years may offer a preview of the way plants and animals will respond as the world rapidly warms due to human-caused climate change, according to a University of Michigan ecologist and his colleagues.
The Greek island extinctions also highlight the critical importance of preserving habitat corridors that will enable plants and animals to migrate in response to climate change, thereby maximizing their chances of survival. (more…)
Psychedelically colored wolves depicted by thermal imaging will shed light on how mange affects the survival, reproduction and social behavior of wolves in Yellowstone National Park. (more…)

Finally some good news on the environment, on ecology and on the Giant Panda: a revolutionary new technique developed by the PR China’s Chengdu breeding center seems certain to assure that greater numbers of this endangered species can be raised in thereby save it from extinction.
Just 1,600 Giant Pandas live in the wild, in 40 government-controlled panda reserves in the People’s Republic of China. The new breeding program has raised the number of animals bred in captivity to 300, while just this year 19 cubs have been born after artificial insemination programs in China’s two main breeding centers.
Breeding Giant Pandas in captivity is no easy task. They have the strangest gestation period which can range from eleven weeks to eleven months, they appear not to be sexually aroused by being held in captivity, females are on heat for 72 hours a year and are fertile during a 12 to 24-hour window inside that period. The small size of the male penis also means the mating position has to be exactly right, and this is not always possible in captivity. (more…)

Researchers at the Hawai‘i Institute of Marine Biology (HIMB), an organized research unit in the University of Hawai‘i at Mānoa’s School of Ocean and Earth Science and Technology have made a remarkable new discovery.
Coral reef ecosystems are one of the most diverse habitats on the planet, providing habitat for a wide variety of marine animals. Unfortunately, coral reefs and their associated fish, algae, and invertebrate species are in worldwide decline. In 2009, 83 rare corals were petitioned to be listed under the United States Endangered Species Act. The National Oceanic and Atmospheric Administration (NOAA) National Marine Fisheries Service is currently reviewing the status of the coral on the petition. If the listing is granted, it will afford higher protection and designate critical habitat for these corals. But are all the ‘species’ on this list really species? (more…)
