(12/03/2013) Bigger than all of Brazil, among the harshest ecosystems on Earth, and largely undeveloped, one would expect that the Sahara desert would be a haven for desert wildlife. One would anticipate that big African animals—which are facing poaching and habitat loss in other parts of the world—would thrive in this vast wilderness. But a new landmark study in Diversity and Distributions finds that the megafauna of the Sahara desert are on the verge of total collapse.
Elusive giraffe-relative - the okapi - now listed as Endangered
(11/26/2013) The discovery of the okapi shocked the world in 1901. African explorer, Henry Stanley, called it 'donkey-like,' while others thought it a new species of zebra, given the stripes. However, this notoriously-secretive rainforest ungulate proved to be the world's only living relative of the giraffe, making it one of most incredible taxonomic discoveries of the Twentieth Century as well as one of the last large-bodied mammals to be uncovered by scientists. But the future of the okapi (Okapia johnstoni) is increasingly in doubt: a new update of the IUCN Red List released today has raised the threatened level for the okapi from Vulnerable to Endangered.
Armored giant turns out to be vital ecosystem engineer
(10/24/2013) The giant armadillo (Priodontes maximus) is not called a giant for nothing: it weighs as much as a large dog and grows longer than the world's biggest tortoise. However, despite its gigantism, many people in its range—from the Amazon to the Pantanal—don't even know it exists or believe it to be more mythology than reality. This is a rare megafauna that has long eluded not only scientific study, but even basic human attention. However, undertaking the world's first long-term study of giant armadillos has allowed intrepid biologist, Arnaud Desbiez, to uncovered a wealth of new information about these cryptic creatures. Not only has Desbiez documented giant armadillo reproduction for the first time, but has also discovered that these gentle giants create vital habitats for a variety of other species.
Tapirs, drug-trafficking, and eco-police: practicing conservation amidst chaos in Nicaragua
(10/10/2013) Nicaragua is a nation still suffering from deep poverty, a free-flowing drug trade, and festering war-wounds after decades of internecine fighting. However, like any country that has been largely defined by its conflicts, Nicaragua possesses surprises that overturn conventional wisdom. Not the least of which is that the Central American country is still home to big, stunning species, including jaguars, giant anteaters, pumas, and the nation's heaviest animal, the Baird's tapir (Tapirus bairdii). Still, not surprisingly given the nation's instability, most conservationists have avoided Nicaragua. But tapir-expert Christopher Jordan, who has worked in the country for over four years, says he wouldn't have it any other way.
Nutrient deficiency in Amazon rainforest linked to megafauna extinction
(08/12/2013) Around twelve thousand of years ago, the Amazon was home to a menagerie of giant creatures: the heavily armored glyptodons, the elephant-sized ground sloth, and the rhino-like toxodons among others. But by 10,000 B.C. these monsters were largely gone, possibly due to overhunting by humans or climatic changes. There's no question that the rapid extinction of these megafauna changed the environment, but a new study in Nature Geoscience posits a novel theory: did the mass extinction of big mammals lead to nutrient deficiency, especially of nitrogen, in parts of the Amazon rainforest?
Connecting kids through elephants: innovative zoo program links children in the UK and India
(05/30/2013) You may think children in urban, northern UK have little in common with those in rural Assam, India, but educational connections are possible you just have to know where to look. In this case, an innovative education initiative at Chester Zoo has employed its five ton stars—the Asian elephants—to teach British children about life in faraway India.
Kenya getting tough on poachers, set to increase fines and jail time
(05/29/2013) The Kenyan parliament has approved emergency measures to tackle the on-going poaching crisis: last week Kenyan MPs approved legislation that should lead to higher penalties for paochers. The emergency measure passed just as Kenya Wildlife Service's (KWS) is pursuing a gang of poachers that slaughtered four rhinos over the weekend. Both rhinos and elephants have suffered heavily as poaching has escalated in Kenya and beyond.
Malaysia may be home to more Asian tapirs than previously thought (photos)
(04/23/2013) You can't mistake an Asian tapir for anything else: for one thing, it's the only tapir on the continent; for another, it's distinct black-and-white blocky markings distinguishes it from any other tapir (or large mammal) on Earth. But still little is known about the Asian tapir (Tapirus indicus), including the number surviving. However, researchers in Malaysia are working to change that: a new study for the first time estimates population density for the neglected megafauna, while another predicts where populations may still be hiding in peninsular Malaysia, including selectively-logged areas.
Bison return to Germany after 300 year absence
(04/18/2013) Earlier this month, officials took down a fence allowing the first herd of European bison (Bison bonasus) to enter the forests freely in Germany in over 300 years, reports Wildlife Extra. The small herd, consisting of just eight animals (one male, five females and two calves) will now be allowed to roam unhindered in the Rothaar Mountains as their ancestors did long ago.
Seeing the forest through the elephants: slaughtered elephants taking rainforest trees with them
(03/11/2013) Elephants are vanishing. The booming illegal ivory trade is decimating the world's largest land animal, but no place has been harder hit than the Congo basin and its forest elephants (Loxodonta cyclotis). The numbers are staggering: a single park in Gabon, Minkebe National Park, has seen 11,100 forest elephants killed in the last eight years; Okapi Faunal Reserve in the Democratic Republic of the Congo has lost 75 percent of its elephants in fifteen years; and a new study in PLoS ONE estimates that in total 60 percent of the world's forest elephants have been killed in the last decade alone. But what does that mean for the Congo forest?
Scientists document baby giant armadillo for first time (photos)
(02/19/2013) Despite weighing as much as full-grown human, almost nothing is known about the giant armadillo (Priodontes maximus) including its breeding and reproductive behaviors. How does mating occur? How long does pregnancy last? How many babes are typically born? Scientists are simply in the dark, but a ground-breaking study employing camera traps is beginning to change this. For the first time, scientists in the Brazilian Pantanal have documented giant armadillo breeding and the happy outcome: a baby giant armadillo.
Photos: Scientists discover tapir bonanza in the Amazon
(01/22/2013) Over 14,000 lowland tapirs (Tapirus terrestris), also known as Brazilian tapirs, roam an Amazonian landscape across Bolivia and Peru, according to new research by scientists with the Wildlife Conservation Society (WCS). Using remote camera trapping, thousands of distribution records, and interviews, the researchers estimated the abundance of lowland tapirs in the Greater Madidi-Tambopata Landscape Conservation Program made up of three national parks in Bolivia (Madidi, Pilón Lajas and Apolobamba) and two in Peru (Tambopata and Bahuaja Sonene).
Three developing nations move to ban hunting to protect vanishing wildlife
(01/21/2013) Three developing countries have recently toughened hunting regulations believing the changes will better protect vanishing species. Botswana has announced it will ban trophy hunting on public lands beginning in 2014, while Zambia has recently banned any hunting of leopards or lions, both of which are disappearing across Africa. However, the most stringent ban comes from another continent: Costa Rica—often considered one of the "greenest" countries on Earth—has recently passed a law that bans all sport hunting and trapping both inside and outside protected areas. The controversial new law is considered the toughest in the Western Hemisphere.
Asia's third largest animal may be on the rebound
(01/17/2013) Unlike Asia's largest animal (the elephant) and its second largest (the rhino), the wild yak—the third largest animal on the world's biggest continent—rarely makes headlines and is never paraded by conservation groups to garner donations. Surviving on the top of the world, in the Tibetan-Qinghai Plateau, the wild yak (Bos mutus) lives it life out in such obscurity that even scientists know almost nothing about it.
Key mammals dying off in rainforest fragments
(08/15/2012) When the Portuguese first arrived on the shores of what is now Brazil, a massive forest waited for them. Not the Amazon, but the Atlantic Forest, stretching for over 1.2 million kilometers. Here jaguars, the continent's apex predator, stalked peccaries, while tapirs waded in rivers and giant anteaters unearthed termites mounds. Here, also, the Tupi people numbered around a million people. Now, almost all of this gone: 93 percent of the Atlantic Forest has been converted to agriculture, pasture, and cities, the bulk of it lost since the 1940s. The Tupi people are largely vanished due to slavery and disease, and, according to a new study in the open access journal PLoS ONE, so are many of the forest's megafauna, from jaguars to giant anteaters.
Humans killed off magnificent Australian megafauna, flipping rainforest into savannah
(03/27/2012) The theory that humans, and not climate change, was primarily responsible for the extinction of giant marsupials in prehistoric Australia takes another step forward with a new study in Science. Exploring sediment cores for past evidence of big herbivores, researchers found that the arrival of humans coincided with the loss of a menagerie of magnificent beasts, from giant kangaroos to fearsome marsupial lions and monster birds to Komodo dragon-like reptiles. The decline of this megafauna ultimately led to ecological changes that may have caused Australia's rainforest to become savannah.
When giant coyotes roamed the Earth
(02/27/2012) Not long ago, geologically speaking, coyotes (Canis latrans) were bigger and more robust than today's animals. In the late Pleistocene, over 10,000 years ago, coyotes rivaled grey wolves (Canis lupus) in size. But, according to a new paper in the Proceedings of the National Academy of Sciences (PNAS), coyotes shrunk significantly following the megafaunal extinction—including the disappearance of big herbivores like giant sloths and mastodons and predators like the smilodon—due to changes in prey and predator competition.
Vietnamese rhino goes extinct
(10/25/2011) In 2009 poachers shot and killed the world's last Vietnamese rhinoceros (Rhinoceros sondaicus annamiticus), a subspecies of the Javan rhino, confirms a report from International Rhino Foundation (IRF) and the World Wide Fund for Nature (WWF). The Vietnamese rhino was the last Javan rhino to survive on the Asian mainland and the second subspecies to vanish, following the extinction of the Indian Javan rhino (rhinoceros sondaicus inermis). The Javan rhino is the world's most imperiled rhino species with now only around 50 individuals surviving in a single park on its namesake island in Indonesia.
Loving the tapir: pioneering conservation for South America's biggest animal
(09/11/2011) Compared to some of South America's megafauna stand-out species—the jaguar, the anaconda, and the harpy eagle come to mind—the tapir doesn't get a lot of love. This is a shame. For one thing, they're the largest terrestrial animal on the South American continent: pound-for-pound they beat both the jaguar and the llama. For another they play a very significant role in their ecosystem: they disperse seeds, modify habitats, and are periodic prey to big predators. For another, modern tapirs are some of the last survivors of a megafauna family that roamed much of the northern hemisphere, including North America, and only declined during the Pleistocene extinction. Finally, for anyone fortunate enough to have witnessed the often-shy tapir in the wild, one knows there is something mystical and ancient about these admittedly strange-looking beasts.
Eastern cougar officially declared extinct
(03/02/2011) The Eastern cougar, a likely subspecies of the mountain lion, was officially declared extinct today by the US Fish and Wildlife Service, ending 38 years on the Endangered Species List (ESA). The cougar, which once roamed the Eastern US, had not been confirmed since 1930s, although sightings have been consistently reported up to the present-day.
Monster turtle killed off by man
(08/17/2010) Researchers have linked another extinction to human beings: this time of a massive prehistoric horned turtle. Prehistoric turtles in the Meiolania genus were thought to have vanished some 50,000 years ago. However, scientists have found a new species that was likely wiped out by human hunters much more recently.
