Protected Dingoes Stay Put

A recent study of dingoes in the Blue Mountains challenges the postcard image of dingoes as only being white pawed and sandy coloured

A recent study of dingoes in the Blue Mountains challenges the postcard image of dingoes as only being white pawed and sandy coloured.

Brad Purcell, a PhD candidate in the University of Western Sydney's School of Natural Sciences, closely followed dingoes using GPS tracking and infra red cameras in the remote Southern Greater Blue Mountains World Heritage Area, approximately 80 kilometres from the centre of Sydney.

A Greener Bowl

Four eco-friendly initiatives at the big game

On the surface, the only thing green about the Super Bowl is the 95,000 square feet of brand new turf (at a cost of US$85,000) they require to be brought into the host of the big game (okay, come to think of it, that's not very green at all). But, the NFL is doing what they can to give the appearance of being a neutral event in the decaying of our environment.

Sleep, Hide: Survive

Nature's sleepy recluses may be better equipped than more outgoing animals

Lazy? Shy? Live in a cave? Those might not be positive attributes for the average human, but they sure are good for animals trying to survive in a changing environment. According to a new study in the journal The American Naturalist, beasts that hibernate, burrow, or crawl into holes in things are less likely to be listed as endangered than those that don’t.

Diminishing Days for Emperor Penguins

A new study suggests that if Antarctic ice continues melting at its current rate, the famed penguins will be near-extinct within the century

No more happy feet for Emperor Penguins. According to a new study, if Antarctic ice continues to shrink at its current pace, Emperor Penguins will face extinction within the next 100 years.

Emperor Penguins are one of only two open-sea Antarctic penguin species and depend on the sea ice for survival. After breeding, Emperor Penguins feed among the coastal pack ice where stretches of water are exposed. As a result of disappearing ice, the Emperor Penguins are being forced to retreat inward and could easily become displaced by other animals, losing out on nesting space.

Anderson Cooper on Great Whites

A firsthand account of viewing the sharks, up close

CNN: It is an odd sensation. Lowering yourself into water teeming with great white sharks. There is a cage between you and the sharks, but its open on the top, and when the first shark emerges from the shadows, moving full speed toward you, its giant mouth open, revealing rows of razor sharp teeth, the cage is little comfort.

Saudi Arabia's Jurassic Park

Beneath Saudi Arabia’s blazing sun, the largest greenhouse ever planned is taking shape. It will take visitors on a walk through Earth’s history—and into its future

A Stroll through Botanic History: The crescent-shaped greenhouse at King Abdullah International Botanical Gardens, rendered here, will be the size of 15 football fields, making it four times as big as the world’s current largest greenhouse.
It’s hard to imagine it raining in Riyadh. Less than five inches of water fall from the clouds above Saudi Arabia’s capital city each year. When the thermostat rises above 110°F, it’s not a heat wave—it’s midday. But it wasn’t always like this. A little over three million years ago, before climate-change cycles turned the area into a desert, the Arabian Peninsula’s empty riverbeds were overflowing valleys, and its dry expanses of shrubland were lush grasslands.

Masters of Disguise

Stunning pictures of some of North America's most impressive animal camouflage

Animals use camouflage to hide from and confuse predators and prey. For some such animals, their natural appearance mimics, matches, and fades into their surroundings. Others actively shift shape, texture or color to blend in. This amazing ability to hide in plain sight has evolved in parallel across thousands of species, and each animal’s cloaking technique is unique.

Dino-aged Reptile Makes a Comeback

The world's oldest lizard-like reptile, with roots dating back to the Triassic period, has been found breeding again for the first time in 200 years

He is greenish brown, has dragon scales for skin, grows up to 32 inches and is the world's last remaining lizard-like reptile that has a lineage dating back to about 225 million years when dinosaurs still roamed the earth—he's a tuatara and he's making a comeback. A species native to New Zealand, the tuatara was spotted nesting in a sanctuary close to Wellington last week, the first such sighting in 200 years. Staff at the 620-acre Karori Wildlife Sanctuary stumbled upon four white, leathery ping-pong sized tuatara eggs during routine maintenance work at the end of last week.

As human populations grow, pollution soils the environment and infrastructure develops, our natural habitat suffers. This may sound familiar, but scientists sent a resounding message today when they announced in a comprehensive five-year global wildlife review that these human-based causes and more are threatening one in four of the world's 5,487 known mammal species and have put 188 species in the critically endangered category.
