Endangered Asiatic Cheetahs
Are Spotted by Iranian Conservationists
Iranian conservationists have spotted a rare Asiatic cheetah with four cubs, offering hope that the large cats can be pulled back from the brink of extinction. Only 40 to 70 Asiatic cheetahs exist today, all in Iran. Over the
weekend, conservationists with the Persian Wildlife Heritage Foundation (PWHF) spotted the five cheetahs in Khar Turan national park in northern Iran. "In the past year or so that we closely monitored Turan, we never spotted a family, especially female cheetahs with cubs," Delaram Ashayeri, project manager at PWHF, told the Guardian
. "It shows Asiatic cheetahs are surviving, breeding cubs are managing to continue life. It's good news against a barrage of bad news about these animals." Iranian conservationists have been involved in a decade-long campaign to protect the cheetahs and educate indigenous people living near them. But sanctions imposed by Western nations over Iran's nuclear program have hampered these efforts, making it difficult to secure international funding and equipment, such as camera traps.

Animals May Play Significant
Role in Carbon Cycling, Researchers Say
Wildlife may play a more important role in the global carbon cycle than researchers have previously given it credit for, according to a study
from an international group of scientists. Although models generally include
Muskoxen in Alaska
carbon cycling by plants and microbes, they often ignore the ways animals contribute to the process. That's a mistake, says Oswald Schmitz, an ecologist at Yale who led the study, because the actions of wildlife can affect carbon cycling through "indirect multiplier effects." For example, the massive loss of trees in North America triggered by the pine beetle outbreak has caused a net carbon change on scale with British Columbia's current fossil fuel emissions, the researchers reported in Ecosystems
. And in the Arctic, where about 500 gigatons of carbon is stored in permafrost, large grazing mammals like caribou and muskoxen can help maintain the grasslands that have a high albedo and thus reflect more solar energy. "We're not saying that managing animals will offset these carbon emissions," Schmitz said. "What we're trying to say is the numbers are of a scale where it is worthwhile to start thinking about how animals could be managed to accomplish that."

Agricultural Ammonia Emissions
Threatening U.S. National Parks, Study Finds
Ammonia emissions from agricultural fertilizers are threatening sensitive ecosystems in U.S. national parks, a study led by Harvard researchers
has found. Thirty-eight national parks are seeing nitrogen deposition levels at or above the threshold for ecological damage,
Great Smoky Mountains N.P.
the study says. In natural ecosystems, excess nitrogen can disrupt nutrient cycling in soil
, cause algal overgrowth, and make aquatic environments acidic. While some of that nitrogen comes in the form of nitrogen oxides (NOx) from power plants and vehicle exhaust, existing air quality regulations and new clean energy technologies are helping reduce NOx emissions. Ammonia emissions from agricultural operations, however, are expected to climb as demand for food and biofuels surges. Daniel Jacob, who led the study, said that because ammonia is volatile, only 10 percent of the nitrogen makes it into the food, with much of it escaping through the atmosphere and being deposited across the landscape. According to the report, published in Atmospheric Chemistry and Physics
, hardwood trees, such as those shown above, are most sensitive to excess nitrogen in eastern temperate forests, while in western national parks lichens appear to suffer first.

Nutrient Recycling by Sponges
Is Vital in Sustaining Reefs, Study Says
Sponges are the unsung heroes of coral reefs, helping the vibrant ecosystems thrive in the marine equivalent of a desert, a Dutch team working in the Caribbean has found
. Scientists had long questioned how reefs, some
of the most productive communities on earth, were able to survive in low-nutrient tropical seas. Bacteria help recycle some nutrients, but the so-called "microbial loop" can't account for the high rates of carbon, nitrogen, and phosphorous recycling needed to maintain a coral reef, researchers say. Sponges fill that void by drawing in plankton and organic matter expelled by the corals and shedding cells that other reef organisms ingest as food, the researchers report in Science
. The "sponge loop," as the Dutch team calls the process, recycles 10 times more organic material than bacteria do and produces as many nutrients as all other primary producers in a coral reef combined, they say.

Small Rainforest Predators
Are Photographed and Studied in Gabon
The west African country of Gabon is known for its gorillas, elephants, and other large animal species, but a recent study
has shed light on little-known rainforest predators that could face increasing pressure from the
bushmeat trade. Using camera traps, bushmeat surveys, and DNA analyses, researchers from Panthera, the Wildlife Conservation Society, and other groups completed the first-ever survey of 12 small carnivore species throughout the country. The study found two species — the common slender mongoose and the Cameroon cusimanse — that hadn't been found in Gabon before, and it documented an extended range for the Egyptian mongoose. “It appears that these species are widespread and not currently threatened, but the proximity of many small carnivores to human settlements and the growing bushmeat trade could potentially impact these populations," said Wildlife Conservation Society researcher Fiona Maisels, who co-authored the study. "These new findings will help inform future management."

Major Initiative Announced
To Help Curb Elephant Poaching in Africa
The Clinton Global Initiative and 16 conservation organizations have announced that they are investing $80 million
over three years to stem the epidemic of elephant poaching in Africa, which has surged recently due to increasing demand for ivory in Asia. The Partnership to Save Africa's Elephants, which includes the governments of seven African nations, will fund programs that scale up anti-poaching enforcement, combat trafficking at ports and markets with more enforcement and harsher penalties, and curb the demand for illegal ivory with ad campaigns aimed at consumers in China, Vietnam, and other nations. "We cannot hope to reverse the dramatic decline in elephant populations without addressing all three parts of the problem," said Patrick Bergin, CEO of the African Wildlife Foundation.

More Than 80 Elephants Dead
From Cyanide Poisoning in Zimbabwe Park
Poachers poisoned watering holes with cyanide in Zimbabwe's Hwange National Park, killing 81 elephants
in the latest wave of slayings to supply the trade in illegal ivory. The cyanide, poured into remote watering
Hwange National Park
holes in the park, also killed smaller animals and vultures that ate the poisoned carcasses. Park rangers arrested nine alleged poachers after following them to a cache of ivory tusks hidden in the park. The elephant death toll of 81 includes 41 carcasses found earlier this month following another cyanide poisoning incident in Hwange park. Zimbabwe's new environment minister, Saviour Kasukuwere, has pledged to make jail penalties for poachers harsher. Elephant and rhino poaching in Africa
has accelerated in recent years due to increasing Asian demand for ivory and rhino horn, which is used in traditional medicines, even though it has no proven medicinal properties. Officials estimate tens of thousands of elephants are being slaughtered each year in the worst wave of poaching in decades.

Migration of Trees Is
Not Keeping Pace with Warming
Most tree species in the U.S. aren't migrating northward as rapidly as predicted in response to climate change, a new study says
. Looking at 65 species across
Kilmer Forest, North Carolina
31 eastern states, the team found no consistent, northward migration of tree species, as many other climate studies have predicted. Rather than shifting northward by dispersing seeds to cooler climates, the researchers found, tree species are responding by speeding up their life cycles. "Most trees are responding through faster turnover," says lead scientist James Clark
of Duke University, "meaning they are staying in place but speeding up their life cycles in response to longer growing seasons and higher temperatures." The results appear in Global Change Biology

Crop Pests Migrate Poleward
Due to Global Warming, Study Says
Global warming has been driving crop pests toward the North and South poles at a rate of 1.7 miles per year, according to new research from the U.K. Looking at the
Stem rust (Puccinia graminis fungus)
distribution of 612 crop pests over the past 50 years, the researchers found a strong correlation between warming global temperatures and increased ranges for the pests. “If crop pests continue to march polewards as the Earth warms, the combined effects of a growing world population and the increased loss of crops to pests will pose a serious threat to global food security,” said Daniel Bebber, a biologist at the University of Exeter who led the study published in Nature Climate Change
. Crop pests — which include insects as well as bacteria, fungi, viruses, and nematodes — destroy 10 to 16 percent of the world's crops each year, or enough food to feed nine percent of the population, scientists estimate.

Mexican Gray Wolves
Granted Increased Protection in the U.S.
The U.S. government has agreed to expand the territory
where a small population of Mexican gray wolves in the southwestern U.S. can be protected and reintroduced.
Mexican gray wolf
Under a pair of agreements with the non-profit Center for Biological Diversity, the U.S. Fish & Wildlife Service also has consented to a plan under which Mexican gray wolves that cross the U.S.-Mexico border and establish territories in Arizona and New Mexico will no longer be captured by U.S. authorities. The agency will also start releasing captive Mexican gray wolves into Gila National Forest and allow them to establish territories throughout much of New Mexico and Arizona. That rule, set to be finalized by January 2015, significantly expands the habitat for a beleaguered population of about 75 Mexican gray wolves
in those states. Wildlife ecologists have been advocating for such measures, saying increased protections and expanded territories are essential to the recovery of the Mexican wolf population, but states in the region have strongly opposed such an expansion.

Thai Monkeys May Abandon
Stone Tools Due to Human Disruptions
Human disturbances in Thailand’s Laem Son National Park may be causing Burmese long-tailed macaques to abandon their use of stone tools, say researchers studying the primates
. The only monkeys in Asia to use
stone tools — and one of only three non-human primates worldwide to do so — these Burmese macaques have learned to use coastal rocks to crack the hard-shelled crabs, snails, and oysters that make up their diet. Habitat loss to rubber and oil palm farming, competition with humans for food sources, and threats from domestic dogs are forcing the macaques to change their foraging habits, researchers from Singapore’s Nanyang Technological University report. The monkeys are also showing signs of acclimating to humans and becoming dependent on human food sources.

Google ‘Street View’ Will
Document Changes to World's Coral Reefs
Marine biologists are teaming up with Google to photograph detailed 360-degree panoramas of coral reefs around the globe. Using technology similar to
Google’s Street View feature, users will be able to survey coral reefs much like they might scope out a city block. The project, Google Street View Oceans
, has already surveyed a 150-kilometer stretch of the Great Barrier Reef and is now working on reefs in the Caribbean
. "Only 1 percent of humanity has ever dived on a coral reef, and by making the experience easily accessible the survey will help alert millions of people around the world to the plight of coral reefs," said Ove Hoegh-Guldberg, a marine biologist at the University of Queensland in Australia who is leading the survey. Image recognition software will log the distribution and abundance of marine organisms, and the researchers hope "citizen scientists" viewing the reefs will help assess other key measures of reef health.

study. After comparing the results of a recent survey of 27 plants found on Mount Lemmon, a 9,157-foot peak near Tucson, Ariz., with a similar survey conducted in 1963, researchers at the University of Arizona found that three-quarters of the plants have shifted their range “significantly” upslope in the last five decades. In some cases, researchers found that the plants had moved upward by as much as 1,000 feet, into a much narrower elevation range than where the plants existed in the early 1960s. Writing in the journal Ecology and Evolution
, the researchers note that the lowermost boundary for 15 of the species has shifted upslope.

Bears Using Wildlife Corridors
In Canadian Park, Genetic Tests Show
Genetic testing has revealed that bears in Canada’s Banff National Park routinely cross the bridges and underpasses along the Trans-Canada Highway
, evidence that the ecological corridors provide safe
A grizzly passes through a Banff underpass
passage along a busy roadway that otherwise threatens to fragment wildlife habitat
. Using 420 wire snag “hair traps” and 497 rub trees at 20 crossings to collect hair from passing bears, researchers from Montana State University determined that 15 individual grizzly bears and 17 individual black bears used the passages over a three-year period. According to researchers, those accounted for about 20 percent of the park’s bear populations, suggesting the passageways are providing enough connectivity to maintain a healthy ecosystem for bears and other large mammals. Twenty-five passages were installed in the 1990s
when the government widened a highway that includes a 100-mile stretch bisecting Banff.

A surge in urban beekeeping may be doing more harm than good to honeybee populations
, according to UK scientists. As the number of rooftop hives increases in cities worldwide
— including London, where there are
A Berlin beekeeper
now 10 hives per square kilometer — two researchers from the University of Sussex warn that too many hives can be detrimental. Writing in The Biologist
, the magazine of the Society of Biology, they suggest that inexperienced beekeepers can create conditions in which there isn’t enough food for their insects. “If there are too many colonies in an area, then the food supply will be insufficient,” Francis Ratnieks, a professor at the university’s Laboratory of Apiculture and Social Insects, told the BBC. “This will mean that colonies do not thrive, and may also affect other species that also visit flowers.”

researchers says. In a study conducted across 17 U.S. states and two Canadian provinces, from southern Texas to Alberta, biologists from Canada, the U.S., and Australia tracked the northward migration of the monarchs, documenting five generations in a single breeding season. By analyzing a chemical signature found on the adult butterflies’ wings that reveals their specific birthplace, scientists were able to track the different generations of butterflies as they migrated north to the U.S. Midwest, from which many butterflies then traveled to Alberta. According to Tyler Flockhart, a Ph. D. student at the University of Guelph in Canada and lead author of the study published in the Proceedings of the Royal Society B
, the decline in milkweed and a surge in genetically modified crops might be affecting monarch survival.

New Deep-Rooted Rice
Shows Greater Resistance to Drought
Japanese scientists say they have developed a rice plant with deeper roots
that could yield a more drought-resistant variety of rice. Writing in the journal Nature Genetics
, a team of scientists describes the discovery of gene that causes a rice strain known as Kinandang Patong, grown in the dry upland of the Philippines, to send longer roots into the soil, allowing the plant to extract water from deeper soil layers. After splicing the gene with a commonly grown rice strain, called IR64, the scientists found that the maximum root depths were more than twice those of the typical plants. After exposing both strains to moderate and severe drought conditions, the researchers found that yields of the standard variety fell significantly in moderate drought conditions and collapsed altogether in severe drought, while the modified strains were not affected by moderate drought and yields declined only 30 percent in severe drought.

Whales Shown to Flee
From Mid-Frequency Military Sonar
Two new studies show that the use of military sonar can provoke whales to flee
, providing evidence that the naval operations may be a factor in mass strandings of whales and dolphins worldwide. According to one study
A blue whale
most marine mammal strandings related to naval sonar exercises involve beaked whales, a notoriously shy species that responds to noise levels well below those used by the U.S. Navy. Scientists believe the beaked whales may interpret the sonar noises as the sounds of killer whales. A separate study
found that even mid-frequency sonar affected the behavior of blue whales, the largest animals on earth, especially during feeding. After exposing tagged blue whales to simulated military sonar and other mid-frequency sounds, the animals often ceased feeding, increased swimming speeds, and traveled away from the sound. “Noise pollution threatens vulnerable populations, driving them away from areas important to their survival, and at worst injuring or even causing the deaths of some whales and dolphins,” Sarah Dolman of the non-profit group Whale and Dolphin Conservation told the Guardian

Return of Yellowstone Wolves
Triggers Surge in Grizzly's Prized Berries

Journal of Animal Ecology
Yellowstone National Park
Grizzly bear at Yellowstone Park
, scientists from Oregon State University and the University of Washington report that the percentage of fruit found in bear scat has nearly doubled during the month of August in recent years. According to researchers, this reflects a recovery of berry bushes triggered in large part by the wolves, which have reduced overbrowsing by the park’s elk herds. The removal of wolves for most of the 20th century triggered the demise of the park’s young aspen and willow trees, as well as berry-producing shrubs, scientists say. According to the report, berries may be so important to the health of bear populations that their recovery could mean a lifting of the species’ “threatened” status under the Endangered Species Act

Wired Honeybees Show
Harmful Impacts of Pesticides on Navigation
Using tiny radar antennae glued to the backs of honeybees, European scientists have found that bees exposed to neonicotinoid pesticides were more likely to become disoriented
and separated from their hives.

After attaching the small transponders to 200 bees, including some that were fed pesticide-laced syrup, scientists discovered that the exposed bees had difficulty navigating and were unable to retrace the path back to their hives. “We find the control bees are just fantastic — they use their landscape and their vector memory and they do fine,” Randolf Menzel, an insect neurobiologist at the Free University in Berlin, told the London Telegraph
. “The treated bees, depending on the doses of the substance, are more confused.” The findings appear to support a theory that neonicotinoids make bees more vulnerable to pathogens and could be a factor in so-called “colony collapse disorder,” a phenomenon that has decimated honeybee populations
in recent years.

study. Demand for the luxurious wool, which has spurred a multibillion-dollar industry, has encouraged herders in Asia to drastically increase their livestock, which are devouring a growing share of the grass that had previously been eaten by antelope, wild asses, and their predators. In an analysis conducted in Mongolia, India, and China’s Tibetan Plateau, a team of researchers concluded that 95 percent of forage is now consumed by domestic animals, leaving just 5 percent for wild species, the Guardian reports
. In addition, the researchers noted a rise in the killing of leopards and wolves by herders following predator attacks on livestock, as well as the transfer of disease from livestock to wild animals. “Rather than serving as symbols of success, these species will become victims of fashion,” the researchers write in the journal Conservation Biology

European Fish Stocks
Show Signs of Recovery, Study Says
A major assessment of fish stocks in the northeast Atlantic Ocean shows that many species are recovering and are now being fished sustainably.
The surprising findings, reported in the journal Current Biology,
are based on data from government research institutes that collected millions of measurements of fish, both at sea and in markets. The study showed that for the first time in decades the majority of fish stocks in the northeast Atlantic are recovering, thanks to reforms instituted by individual nations and the European Union in 2002. This good news comes amid widespread criticism of EU fisheries policies
, which recently have undergone further reform. “We should be aware that low fishing pressure needs to be maintained until stocks recover,” said researcher Robin Cook of the University of Strathclyde in Scotland. “This is only the first step. Now we need to see numbers increase as a result of continued low fishing pressure.”

Malaysian Borneo Plundered
As 80 Percent of Rainforests Are Logged
The first comprehensive, satellite-based assessment of industrial logging practices in Malaysian Borneo has shown that more than 80 percent of the region’s forests have been heavily impacted by logging
. Reporting in the journal PLOS One
, researchers from Australia,
New Guinea, and the U.S. say that Malaysian Borneo — which just 30 years ago was considered one of the wildest places on Earth — now has been eaten away by 226,000 miles of roads that have enabled companies to legally and illegally log most of the territory, which consists of the Malaysian states of Sabah and Sarawak. At best, only 17,500 square miles of forest ecosystems remain intact, the study said. “The extent of logging in Sabah and Sarawak documented in our work is breathtaking,” said study co-author Phil Shearman of the University of Papua New Guinea.

New App Identifies Species
By Recordings of Their Vocalizations
A new app is enabling scientists and the public to automatically identify frogs, birds, insects, monkeys, and other animals by recording their vocalizations.
Scientists at the University of Puerto Rico have created a system called the Automated Remote Biodiversity Monitoring Network (ARBIMON) that enables them to place inexpensive, solar-powered technology in the field and record the sounds of creatures that are often difficult to see or locate in their natural environment. The devices, which include I-Pods, can make 144 one-minute recordings per day and transmit them to a base station miles away. Using the ARBIMON system
, scientists have already made more than 1 million recordings in Puerto Rico, Hawaii, Arizona, Costa Rica, and Brazil that can be listened to online. Researchers say the new system will greatly enhance their ability to do field research and to monitor the presence and activity patterns of species.

caught and photographed in 2009 during a routine sampling for avian influenza, the small wren-sized bird was initially misidentified as a known type of tailorbird until the photographs caught the attention of scientist Simon Mahood of the Wildlife Conservation Society. Following genetic analysis of other individuals collected in the region, scientists confirmed that the bird — which has white cheeks, a rich cinnamon-colored crown, and distinct vocal characters — was indeed a new species. According to an article co-authored by Mahood in Forktail

avian populations worldwide. The U.S. Fish and Wildlife Service (FWS) reports that numbers of some migratory bird populations in Maine — including Arctic terns and puffins — have plummeted in recent years
because their food supplies are disappearing as a result of commercial fishing and the shifting of fish to cooler waters, which is making it more difficult for some birds to feed their young. In a separate study, scientists predict that rising sea levels will devastate habitat for some migratory shore birds
in the coming decades. Higher sea levels, the study predicts, will flood 23 percent to 40 percent of the intertidal habitats for several shorebird species, triggering population declines of as much as 70 percent. Overall, one in eight bird species globally is at risk of extinction

Bird-Mimicking Mobile Apps
Harmful to Species, UK Groups Say
Wildlife officials in the UK are urging people not to use mobile phone apps that mimic bird songs in nature reserves, warning that the devices can harm some sensitive species
, particularly during breeding season.
Icon for Chirp! app
The increasingly popular apps, which use recordings of bird calls to lure the birds closer for photographs or better viewing, can distract birds from critical tasks, such as feeding their young, according to the Royal Society for the Protection of Birds. The Dorset Wildlife Trust (DWT), a conservation group that oversees 42 reserves, is discouraging the use of the mobile apps at its reserves
, calling it an intentional disturbance of sensitive species such as the Nightjar, a nocturnal bird that has experienced a recent recovery in the area. “I’m sure visitors would be devastated if they realized the possible disturbance they were causing to wildlife,” said Chris Thain, a manager at DWT’s Brownsea Island reserve.
