(10/21/2014) A number of the world's top conservation scientists have raised concerns about plans for commercial logging on Woodlark Island, a hugely biodiverse rainforest island off the coast of Papua New Guinea. The scientists, with the Alliance of Leading Environmental Scientists and Thinkers (ALERT), warn that commercial logging on the island could imperil the island's stunning local species and its indigenous people.
Outcompeted: Species competition may result in geographic isolation
(10/03/2014) Scientists have long believed that gene flow and species dispersal is only interrupted by physical barriers, like mountain ranges, rivers or even the complete disappearance of a suitable habitat. But new research into the distribution of two mouse opossum species in South America suggests that other factors may play a role as well, such as competition and predation.
Extinction island? Plans to log half an island could endanger over 40 species
(09/22/2014) Woodlark Island is a rare place on the planet today. This small island off the coast Papua New Guinea is still covered in rich tropical forest, an ecosystem shared for thousands of years between tribal peoples and a plethora of species, including at least 42 found no-where else. Yet, like many such wildernesses, Woodlark Island is now facing major changes: not the least of them is a plan to log half of the island.
Desperate measures: researchers say radical approaches needed to beat extinctions
(07/24/2014) Today, in the midst of what has been termed the “Sixth Great Extinction” by many in the scientific community, humans are contributing to dizzying rates of species loss and ecosystem changes. A new analysis suggests the time may have come to start widely applying intensive, controversial methods currently used only as “last resort” strategies to save the word’s most imperiled species.
Tree-huggers: koalas cuddle up to keep cool
(06/06/2014) For animals that live in places that are both hot and dry, using valuable water stores to cool off via evaporation may put them at risk of dehydration. Now, as described in a new study published in Biology Letters, it seems that koalas have figured out a way to stay both cool and dry: by hugging trees.
Loggers plan to clear 20 percent of tropical island paradise
(04/28/2014) Seven years ago, a palm oil company set its eyes on Woodlark Island—a small rainforest island nearly 200 miles off the coast of Papua New Guinea—but was rebuked by the local populace. But locals and conservationists who spoke to mongabay.com at the time felt that wouldn't be the end of it: they were right. Recently, a company, Karridale Limited, has landed machinery on the island.
Scientists uncover new species of Andean marsupial frog
(03/05/2014) The term marsupial frog sound like a hoax, but, believe it or not, it's real. Recently, herpetologists welcomed a new species, known as Gastrotheca dysprosita and described in the journal Phyllomedusa. Unlike mammal marsupials, which typically carry their young in pouches on their torsos and are found primarily in Australia, the Gastrotheca genus of frogs, which contains 62 species, is found in the Andes region on South America and sport their pouches on their backs (also called a "dorsal brood pouch").
New marsupial discovered in Ecuador
(12/20/2013) Researchers working in Ecuador have identified a previously unknown species of shrew-opossum, according to a study recently published in the Journal of Mammalogy. Contrary to its mousey appearance, Caenolestes sangay, named after the national park where it was discovered, is actually a marsupial. The team from Pacific Lutheran University set up more than 100 live traps over 15 nights on the eastern slopes of Andes. In the course of their research they recovered five specimens of the new species, each measuring approximately 10 centimeters (3.9 inches) long.
Loose laws threaten Australia's wildlife
(09/09/2013) Kookaburras, koalas and kangaroos—Australia is well known for its charismatic animals and vast, seemingly untamable, wild spaces. But throughout the country, the national parks and reserves that protect these unique animals and ecosystems have come under increasing threat. New rules and relaxed regulations, which bolster immediate economic growth, are putting pressure on Australia's already-threatened biodiversity.
Last disease-free Tasmanian devils imperiled by mine
(08/07/2013) The federal environment minister, Mark Butler, has given the go-ahead to a controversial mine that the courts halted amid concerns it could drastically affect the last stronghold of the Tasmanian devil. Butler said he had granted approval to Shree Minerals to proceed with its iron ore mine at Nelson Bay River in the north-west of Tasmania, subject to 30 conditions.
Australian logger: finding dead koalas 'a daily thing'
(07/24/2013) Revelations of koalas suffering graphic injuries and death in Victorian timber plantations are evidence of a long-standing failure to properly protect the iconic Australian marsupials, according to a leading conservation organization. Footage on Monday night's 7.30 report showed koalas, including babies, lying dead on the floor of a cleared forest. One koala was missing an arm while another injured animal relocated to a new area of bush was shown to be in visible distress.
Scientist: Australia taking 'calculated actions' to push Leadbeater's possum to extinction
(06/06/2013) Australia's leading scientific expert on the endangered Leadbeater's possum has publicly lambasted the Victorian state government, claiming it is the first ever domestic administration to take "calculated actions" that it knew could wipe out a threatened species. In a letter published in the respected journal Science, Prof David Lindenmayer, of the Australian National University, states that "government-sanctioned legal logging of the reserve system will signiﬁcantly increase the chance of extinction of Leadbeater’s possum."
Saving the Tenkile: an expedition to protect one of the most endangered animals you've never heard of
(06/05/2013) The tenkile, or the Scott’s tree kangaroo (Dendrolagus scottae) could be a cross between a koala bear and a puppy. With it’s fuzzy dark fur, long tail and snout, and tiny ears, it’s difficult to imagine a more adorable animal. It’s also difficult to imagine that the tenkile is one of the most endangered species on Earth: only an estimated 300 remain. According to the Tenkile Conservation Alliance (TCA), the tenkile’s trouble stems from a sharp increase of human settlements in the Torricelli mountain range. Once relatively isolated, the tenkile now struggles to avoid hunters and towns while still having sufficient range to live in.
Could the Tasmanian tiger be hiding out in New Guinea?
(05/20/2013) Many people still believe the Tasmanian tiger (Thylacinus cynocephalus) survives in the wilds of Tasmania, even though the species was declared extinct over eighty years ago. Sightings and reports of the elusive carnivorous marsupial, which was the top predator on the island, pop-up almost as frequently as those of Bigfoot in North America, but to date no definitive evidence has emerged of its survival. Yet, a noted cryptozoologist (one who searches for hidden animals), Dr. Karl Shuker, wrote recently that tiger hunters should perhaps turn their attention to a different island: New Guinea.
Indigenous knowledge reveals widespread mammal decline in northern Australia
(02/14/2013) Over the course of four years, a team of elite Australian researchers journeyed through the remote landscapes of Northern Australia to tap a vanishing resource: the wealth of knowledge carried by the indigenous inhabitants. Their study, published this year in Biological Conservation concludes that there have been major declines in native Northern Australian mammals, and also suggests a relationship between the decline of Indigenous knowledge and the decline of biodiversity.
Cute koalas have become 'urban refugees'
(01/28/2013) According to Susan Kelly, koalas have become "urban refugees," under siege by expanding cities that bring with them deforestation, dogs, traffic, and other ills for native wildlife. Director of Global Witness, and writer, producer and director of the new documentary Koala Hospital, Kelly has spent 3 years working to understand the rising threats to one of the world's most beloved marsupials. While Koala Hospital highlights the many perils facing koalas, including climate change due to record fires across Australia, it also looks at the efforts of individuals who work to save koalas one—by—one at Port Macquarie Koala Hospital, taking in patients who have been orphaned, hit by cars, scarred in fires, or attacked by dogs.
Photos: new mammal menagerie uncovered in remote Peruvian cloud forest
(10/03/2012) Every year scientists describe around 18,000 new species, but mammals make up less than half a percent of those. Yet mammal surprises remain: deep in the remote Peruvian Andes, scientists have made an incredible discovery: a rich cloud forest and alpine grassland ecosystem that may be home to no less than eight new mammal species. Although most of these new mammals are currently under study—and have not been officially described yet (a process which can take several years)—lead scientists, Horacio Zeballos of Peru and Gerardo Ceballos of Mexico are certain they have uncovered a small forest, surrounded by deforestation and farmland, that shelters a remarkable menagerie of mammals unknown to scientists until now.
Cute animal picture of the day: the little-known cuscus
(11/29/2011) Cuscus are marsupials found in Indonesia, Australia, and Papua New Guinea. Dwelling in tropical rainforests, they inhabit a niche similar to monkey, foraging throughout the canopy for leaves and fruit. In some cases cuscus will eat birds and lizards.
Forgotten species: the endearing Tenkile tree kangaroo
(05/03/2011) With their long snout, furry body, soft eyes, and, at times, upright stance, tree kangaroos often remind me of the muppets. Of course, if there were any fairness in the world, the muppets would remind me of tree kangaroos, since kangaroos, or macropods, have inhabited the Earth for at least 5 million years longer than Jim Henson’s muppets. But as a child of the 1980s, I knew about muppets well before tree kangaroos, which play second fiddle in the public imagination to their bigger, boxing cousins. This is perhaps surprising, as tree kangaroos possess three characteristics that should make them immensely popular: they are mammals, they are monkey-like (and who doesn't like monkeys?), and they are desperately 'cute'.
Back from extinction: Tasmanian tiger caught on video?
(11/16/2010) A 9 second video released today on YouTube claims to show a living Tasmanian tiger. The footage was captured by Murray McAllister last year. McAllister says he has seen the believed-to-be-extinct Tasmanian tiger several times in the last few years.
Australian mammals in steady decline even in large National Park
(07/19/2010) Kakadu National Park, one of the Australia's "largest and best-resourced" protected areas, is experiencing a staggering decline in its small mammal population, according to a new study published in Wildlife Research. Spanning nearly 2 million hectares—larger than Fiji—the park lies in tropical northern Australia. 'This decline is catastrophic,' John Woinarski, lead author of the study and expert on Australian mammals, told mongabay.com. 'We know of no comparable case in the world of such rapid and severe decline of a large proportion of native species in a large conservation reserve.'
Photos: more new species found in Indonesia's 'lost world'
(05/17/2010) The Foja Mountains on the Indonesian side of New Guinea have proven a biological treasure trove that just keeps spilling riches. Two-and-a-half years ago the region—dubbed Indonesia's 'lost world'—made news globally when researchers announced the discovery of a giant rat: five times the size of the familiar brown rat. New amphibians, birds, and insects have also been found during past expeditions in 2005 and 2007. A collaborative team of Indonesia and international researchers have since returned to the Foja Mountains and found more spectacular species.
A cure for the Tasmanian devil's strange and fatal cancer?
(11/21/2008) Researchers have announced that two Tasmanian devils have survived a cancer devastating their species after receiving inoculations of dead tumor cells, according to the International Herald. However, the inoculations have not worked on every devil – despite being inoculated four devils died from the cancer during the work.
Extinct since 1963, wild eastern quolls discovered in Australia
(10/16/2008) Two eastern quoll have been found as roadkill on the Australian mainland. Although considered extinct in Australia since 1963, these carnivorous marsupials remain abundant on the island of Tasmania.
