(05/06/2013) Ordinarily, invasive and exotic species are a grave threat to native wildlife: outcompeting local species, introducing parasites and disease, and disturbing local ecological regimes. A unique case in the Brazilian Pantanal, however, has turned the tables; here, an introduced mammal has actually aided the conservation of native wildlife.
Working to save the mystery antelope that's little bigger than a pet cat (photos)
(04/25/2013) Little is known about the silver dik-dik (Madoqua piacentinii) population that roams the dense coastal bushlands of eastern Africa, but experts are working to learn more about the mysterious species. Weighing little more than a domestic cat, the small antelopes are found in a long, narrow coastal strip spreading across 250 kilometers (155 miles) from Somalia's capital of Mogadishu north to the port town of Hobyo. This coastal strip is known as the Hobyo Grassland and Shrubland eco-region, according to the WWF.
Scientists successfully freeze Barbary sheep embryos for conservation purposes
(03/18/2013) The Barbary sheep (Ammotragus lervia), or aoudad, is a goat-antelope found in northern Africa. It is currently listed as Vulnerable by the IUCN Red List, with populations imperiled by hunting, habitat loss, and competition with livestock. Still little is known about its remaining population, prompting scientists in Mexico to test possible assisted reproduction of captive individuals.
Deer populations hurt by poaching in Mexican dry forest
(03/18/2013) White-tailed deer are usually thought of as inhabiting temperate forests in the U.S. and Canada, but this widespread species can also be found across tropical forests, from Mexico to Peru. A new study in mongabay.com's open access journal Tropical Conservation Science investigates the population of white-tailed deer (Odocoileus virginianus) in Mexico's Tehuacan-Cuicatlan Biosphere Reserve (TCBR), and finds that poaching may be having a large impact.
Scientists successfully reintroduce gaur in Indian park
(03/18/2013) Gaur (Bos gaurus gaurus) is one of the large wild ungulates of Asian jungles. It is the tallest living ox, and one of the four heaviest land mammals (elephant, rhino and wild buffalo are the other three), weighing up to 940 kilograms (2,070 pounds) and standing between 1.6 and 1.9 meters (5.2 to 6.2 feet) at the shoulder. Gaur were once distributed throughout the forested tracts of India and South Nepal, east to Vietnam and south to Malaya. Today, however, they are confined to just over a hundred existing, and 27 proposed, Protected Areas in India.
Wolves, mole rats, and nyala: the struggle to conserve Ethiopia's highlands
(11/20/2012) There is a place in the world where wolves live almost entirely off mountain rodents, lions dwell in forests, and freshwater rolls downstream to 12 million people, but the place—Ethiopia's Bale Mountains National Park—remains imperiled by a lack of legal boundaries and encroachment by a growing human population. "Much of the land in Africa above 3,000 meters has been altered or degraded to the point where it isn’t able to perform most of the ecosystem functions that it is designed to do. Bale, although under threat and already impacted to a degree by anthropogenic activities, is still able to perform its most important ecosystem functions, and as such ranks among only a handful of representative alpine ecosystems in Africa."
In midst of rhino poaching epidemic, Lewa Wildlife Conservancy has happy problem: too many black rhinos
(10/02/2012) So far this year, South Africa has lost 430 rhinos to poachers, more than one animal a day. The epidemic of rhino poaching, fueled by demand for black-market powdered rhino horn in Vietnam and China, is decimating rhino species worldwide. In fact, last year saw the official extinction of two rhino subspecies: the Vietnamese rhino (Rhinoceros sondaicus annamiticus), a subspecies of the Javan, and the western black rhino (Diceros bicornis longipes), a subspecies of the black. However there is one place where rhinos still thrive. The Lewa Wildlife Conservancy in Kenya has found itself with a unique, but happy, problem: they have so many black rhinos, which are considered Critically Endangered by the IUNC Red List, that they need to move some to stop rhino-fights. In other words, their rhino population has hit its limit for the 25,000 hectare (62,000 acre) nonprofit protected area.
Conflict and perseverance: rehabilitating a forgotten park in the Congo
(09/19/2012) Zebra racing across the yellow-green savannah is an iconic image for Africa, but imagine you're seeing this not in Kenya or South Africa, but in the Democratic Republic of Congo (DRC). Welcome to Upemba National Park: once a jewel in the African wildlife crown, this protected area has been decimated by civil war. Now, a new bold initiative by the Frankfurt Zoological Society (FZS), dubbed Forgotten Parks, is working to rehabilitate Upemba after not only decades of conflict but also poaching, neglect, and severe poverty.
Bushmeat consumption differs between communities in Tanzania
(09/17/2012) Bushmeat consumption depends on the make-up of individual communities, according to a new study in the open access journal Tropical Conservation Science. By interviewing indigenous groups and refugees living near two protected areas in western Tanzania, researchers found that consumption rates differed significantly, likely based on costliness and access.
Local knowledge matches scientific data on wildlife abundances
(09/17/2012) How far can scientists trust local knowledge when it comes to ecosystems? This is a question that is undergoing heavy debate in scientific circles. A new study in mongabay.com's open access journal Tropical Conservation Science contributes to the debate by finding that basic local knowledge of animal abundance in Gonarezhou National Park, Zimbabwe aligned closely with scientific surveys.
Picture of the day: baby Grevy's zebra
(09/10/2012) Not only is the Grevy's zebra (Equus grevyi) the biggest of the three zebra species, it is also the world's largest wild horse species. Once roaming throughout the horn of Africa, today the species is confined to a few populations in Kenya and Ethiopia.
Conservationists pledge to double number of tiny buffalo
(07/25/2012) Ten thousand mighty tamaraw buffalo (Bubalus mindorensis) once grazed the mountain slopes of Mindoro Island in the Philippines. However, these dwarf buffalo are now classified as Critically Endangered on the IUCN Red List, with fewer than 300 individuals remaining on the small island to which they are wholly endemic. Yet hope remains for the tamaraw: an enormous effort has been mounted to revive this iconic species and to protect its unique island habitat.
Cute animal picture of the day: sitatunga calf
(07/24/2012) The sitatunga (Tragelaphus spekii) is a swamp-dwelling antelope that makes its home in Central and Southern Africa, including the Congo Rainforest. They have waterproof coats and often take to the water to help avoid predators. The sitatunga is listed as Least Concern by the IUCN Red List.
Conservation success: markhor population climbing
(07/24/2012) Pakistan's national mammal, the markhor, is making a remarkable comeback in the country as a result of community conservation efforts, according to the Wildlife Conservation Society (WCS). Surveys this year in the Kargah region of Northern Pakistan's Gilgit Baltistan territory, have estimated 300 individuals of this large wild goat, up from a low of 40-50 animals in 1991. What's more, the surveys suggest that numbers across the whole Gilgit Baltistan territory may have boomed to 1,500 individuals, whereas in 1999, there were believed to be fewer than 1,000 left. This represents an impressive climb—even for the markhor.
Gas development pushing pronghorn out of vital wintering grounds
(05/02/2012) Development of natural gas fields in Greater Yellowstone Ecosystem is pushing pronghorn (Antilocapra americana) out of crucial wintering grounds, a situation that could result in a population decline according to a new study in Biological Conservation. By tracking 125 female pronghorn over five years in Wyoming, researchers found that highest quality habitat had fallen by over 80 percent in two vast gas fields on land owned by the government's Bureau of Land Management (BLM).
Cute animal picture of the day: endangered baby giraffe
(03/29/2012) A baby Rothschild's giraffe (Giraffa camelopardalis rothschildi) was recently born at the Wildlife Conservation Society's (WCS) Bronx Zoo. The subspecies was classified as Endangered in 2010 with a wild population of less than 700 individuals in Kenya and Uganda.
Animal picture of the day: a baby bongo
(03/22/2012) A female bongo (Tragelaphus eurycerus) was born at the Zoological Society of London's Whipsnade Zoo last month. "The calf and her mum are happy to sit with other members of the group and the calf is not always found with mum—babysitting is common with the bongo," Mark Holden, Africa section leader at ZSL Whipsnade Zoo, said in a press release.
Cute animal picture of the day: tufted deer fawn
(08/07/2011) Native to China and, perhaps, Myanmar (Burma), the tufted deer lives in mountainous damp forests.
Decline in top predators and megafauna 'humankind’s most pervasive influence on nature'
(07/14/2011) Worldwide wolf populations have dropped around 99 percent from historic populations. Lion populations have fallen from 450,000 to 20,000 in 50 years. Three subspecies of tiger went extinct in the 20th Century. Overfishing and finning has cut some shark populations down by 90 percent in just a few decades. Though humpback whales have rebounded since whaling was banned, they are still far from historic numbers. While some humans have mourned such statistics as an aesthetic loss, scientists now say these declines have a far greater impact on humans than just the vanishing of iconic animals. The almost wholesale destruction of top predators—such as sharks, wolves, and big cats—has drastically altered the world's ecosystems, according to a new review study in Science. Although researchers have long known that the decline of animals at the top of food chain, including big herbivores and omnivores, affects ecosystems through what is known as 'trophic cascade', studies over the past few decades are only beginning to reveal the extent to which these animals maintain healthy environments, preserve biodiversity, and improve nature's productivity.
Best way to count white-tailed deer populations in tropical forests
(06/27/2011) Getting accurate estimates on wildlife populations is difficult in any habitat, but especially tricky in tropical forests where even large mammals are capable of melting into the foliage like ghosts. If you've ever spent time in a tropical rainforest, you know you could walk within a couple meters of a jaguar and never even know. Therefore, scientists have to come up with creative ways—from camera traps to pawprints to studying feces—to estimate population size. In the new issues of mongabay.com's open access journal Tropical Conservation Science, researchers look at the most accurate way to count white-tailed deer (Odocoileus virginianus) in central Mexican forests.
How do we save the Sumatran rhino?
(06/06/2011) Some conservation challenges are more daunting than others. For example, how do you save a species that has been whittled down to just a couple hundred individuals; still faces threats such as deforestation, poaching and trapping; is notoriously difficult to breed in captivity; and is losing precious time because surviving animals are so few and far-apart that simply finding one another—let alone mating and successfully bringing a baby into the world—is unlikely? This is the uphill task that faces conservationists scrambling to save the Sumatran rhino (Dicerorhinus sumatrensis). A new paper in Oryx, aptly named Now or never: what will it take to save the Sumatran rhinoceros Dicerorhinus sumatrensis from extinction? analyzes the conservation challenge, while putting forth a number of recommendations.
