Humans drove rainforest into savannah in ancient Africa

2012-02-09T19:18:00Z

Three thousand years ago (around 1000 BCE) several large sections of the Congo rainforest in central Africa suddenly vanished and became savannah. Scientists have long believed the loss of the forest was due to changes in the climate, however a new study in Science implicates an additional culprit: humans. The study argues that a migration of farmers into the region led to rapid land-use changes from agriculture and iron smelting, eventually causing the collapse of rainforest in places and a rise of grasslands. The study has implications for today as scientists warn that the potent combination of deforestation and climate change could flip parts of the Amazon rainforest as well into savannah.

Another food crisis looming in Africa: nearly 5 million South Sudanese lacking food

2012-02-08T19:10:00Z

The Food and Agriculture Organization (FAO) and the World Food Program (WFP) have warned that South Sudan is facing a food crisis and that immediate action is needed to stave off a disaster. Currently 4.7 million people do not have enough to eat in South Sudan, while one million of these face severe food shortages. That number, however, could double if on-going conflict in the region continues and food prices continue rising, says the UN agencies.

Majority of protected tropical forests "empty" due to hunting

2012-02-08T18:11:00Z

Protected areas in the world's tropical rainforests are absolutely essential, but one cannot simply set up a new refuge and believe the work is done, according to a new paper in Bioscience. Unsustainable hunting and poaching is decimating tropical forest species in the Amazon, the Congo, Southeast Asia, and Oceana, leaving behind "empty forests," places largely devoid of any mammal, bird, or reptile over a few pounds. The loss of such species impacts the whole ecosystems, as plants lose seed dispersers and the food chain is unraveled.

Price of gorilla permit increases to $750/day

Caution urged in sale of Madagascar's illegal timber stockpiles

2012-02-03T23:42:00Z

Confiscated timber stocks in Madagascar must be managed in a "transparent manner" to deter future illegal logging and boosting demand for endangered rainforest timber, says a letter published by a coalition of NGOs.

Photos of the day: a celebration of wetlands (for World Wetlands Day)

2012-02-02T23:21:00Z

Forget the groundhogs, February 2nd is also World Wetland Day, commemorating the historic convention of wetlands in Ramsar, Iran in 1971. The Ramsar Treaty was an international agreement meant to address the loss and degradation of wetlands worldwide.

Frog perfume? Madagascar frogs communicate via airborne pheromones

2012-01-25T21:05:00Z

Researchers have found that some frogs in Madagascar communicate by more than just sound and sight: they create distinct airborne pheromones, which are secreted chemicals used for communicating with others. A paper published in Angewandte Chemie International Edition relates that some male members of the Mantellinae family in Madagascar use large glands on their inner thighs to produce airborne pheromones. Interestingly, the pheromones are structurally similar to those produced by insects. Scientists have identified frogs producing water-borne pheromones before, but this is the first instance of airborne.

Featured video: music in Madagascar to protest illegal logging

2012-01-22T20:35:00Z

A new video highlights the plight of Madagascar's protected tropical forests, which are falling prey to illegal logging and foreign contractors. Featuring Razia Said, Malagasy singer and songwriter, the video shows concerts to raise awareness about illegal logging, especially near Maosala National Park.

Delayed response to Somalia famine cost thousands of lives

2012-01-18T20:51:00Z

A hesitant response by the international community likely led to thousands of unnecessary deaths in last year's famine in East Africa finds a new report released by Oxfam and Save the Children. The report, entitled A Dangerous Delay, says that early warning systems worked in informing the international community about the likelihood of a dire food crisis in East Africa, however a "culture of risk aversion" led to months-long delays. By the time aid arrived it was already too late for many. The British government has estimated somewhere between 50,000 and 100,000 people perished in the famine, half of whom were likely children under five.

Eco-toilets help save hippos and birds in Kenya

2012-01-04T21:09:00Z

It may appear unintuitive that special toilets could benefit hippos and other wetland species, but the Center for Rural Empowerment and the Environment (CREE) has proven the unique benefits of new toilets in the Dunga Wetlands on Lake Victoria's Kenyan side. By building ecologically-sanitary (eco-san) toilets, CREE has managed to alleviate some of the conflict that has cropped up between hippos and humans for space.

Earth systems disruption: Does 2011 indicate the "new normal" of climate chaos and conflict?

2011-12-21T19:02:00Z

The year 2011 has presented the world with a shocking increase in irregular weather and disasters linked to climate change. Just as the 2007 "big melt" of summer arctic sea ice sent scientists and environmentalists scrambling to re-evaluate the severity of climate change, so have recent events forced major revisions and updates in climate science.

Droughts could push parts of Africa back into famine

2011-12-19T15:39:00Z

Drought and erratic rains could lead to further food scarcities in Africa warns the United Nations World Food Program (WFP). The WFP singles out South Sudan, the world's newest nation, and Niger as nations of particular concern. Earlier this year famine killed scores of people, including an estimated 30,000 children, in Somalia.

Cultural shifts in Madagascar drive lemur-killing

2011-12-15T23:32:00Z

Conservationists have often found that some cultural norms, religious beliefs, and taboos play a role in holding back traditional peoples from overusing their environment. Examples of such beliefs include days wherein one cannot hunt or fish, or certain species or regions that are off limits to exploitation. But the influence of the modern world can rapidly extinguish such beliefs, sometimes for the better, in other cases not. In many parts of Madagascar, lemurs are off the menu. These primates, found only in Madagascar, play a big role in Malagasy 'fady' or taboo-related folk stories: lemurs are protectors and, in some cases, even relatives. However, according to a new paper in PLoS ONE an influx of migrants, widespread poverty, lack domestic meat, and poor law enforcement has caused a sudden rise in eating lemurs, many of which are already near-extinction due to habitat loss.

New large horned viper discovered, but biologists keep location quiet

2011-12-15T17:49:00Z

In a remote forest fragment in Tanzania, scientists have made a remarkable discovery: a uniquely-colored horned viper extending over two feet long (643 millimeters) that evolved from its closest relative over two million years ago. Unfortunately, however, the new species—named Matilda's horned viper (Atheris matildae)—survives in a small degraded habitat and is believed to be Critically Endangered. Given its scarcity, its discoverers are working to pre-empt an insidious threat to new species.

Locals key to saving primate-rich wetlands in Cote D'Ivoire

2011-12-12T19:07:00Z

Saved from being converted into a vast palm oil plantation by PALM-CI in 2009, the Ehy Tanoé wetlands and forest in the Cote D'Ivoire (Ivory Coast) is home to three gravely endangered primates and as well as many other species. Since 2006, a pilot community management program has been working to protect the 12,000 hectare area, and a new study in mongabay.com's open access journal Tropical Conservation Science finds that long-term conservation of the Ehy Tanoé wetlands and forest is, in fact, vital for locals who depend on the area for hunting, fishing, firewood, building materials, and medicinal plants. In addition, the study finds that the ecosystem has special cultural and spiritual importance to locals.

Madagascar tree diversity among the highest worldwide

2011-12-12T18:35:00Z

In terms of biodiversity, the hugely imperiled forests of Madagascar may be among the world's richest. Researchers estimate that the island off the coast of Africa is home to at least 10,000 tree and shrub species with over 90 percent of them found no-where else in the world. With little baseline data collected on Madagascar's ecosystems, a new study, the first ever of tree diversity in Madagascar lowland rainforests, hopes to begin the process. Published in mongabay.com's open access journal Tropical Conservation Science, the new study surveyed tree species in eastern Madagascar's Betampona Special Reserve.

Bushmeat trade driving illegal hunting in Zimbabwe park

2011-12-12T12:00:00Z

Bushmeat hunting is one of the major threats to mammals in sub-Saharan Africa. Although widely discussed and recognized as an issues in Central and West Africa, a new study in mongabay.com's open access journal Tropical Conservation Science describes a pattern of bushmeat hunting that is also occurring in southern Africa. Interviewing 114 locals living adjacent to Gonarezhou National Park in Zimbabwe, Edson Gandiwa with Wageningen University found that the primary drivers of illegal hunting in the park were bushmeat and personal consumption (68 percent).

Global carbon emissions rise 49 percent since 1990

2011-12-04T18:21:00Z

Total carbon emissions for the first time hit 10 billion metric tons (36.7 billion tons of CO2) in 2010, according to new analysis published by the Global Carbon Project (GCP) in Nature Climate Change. In the past two decades (since the reference year for the Kyoto Protocol: 1990), emissions have risen an astounding 49 percent. Released as officials from 190 countries meet in Durban, South Africa for the 17th UN Summit on Climate Change to discuss the future of international efforts on climate change, the study is just the latest to argue a growing urgency for slashing emissions in the face of rising extreme weather incidents and vanishing polar sea ice, among other impacts.

Sierra Leone creates rainforest park

Africa, China call out Canada for climate betrayal

2011-12-01T22:59:00Z

Purchasing a full page ad in the Canadian paper the Globe and Mail, a group of African leaders and NGOs is calling on Canada to return to the fold on climate change. Canada has recently all-but-confirmed that after the ongoing 17th UN Summit on Climate Change in Durban, South Africa, it will withdraw entirely from the Kyoto Treaty. The country has missed its targets by a long-shot, in part due to the exploitation of its tar sands for oil, and is increasingly viewed at climate conferences as intractable and obstructive. In the eyes of those concerned about climate change, Canada has gone from hero to villain. Yet notable African activists, including Archbishop Desmond Tutu, are pushing back.

Community mapping of African rainforests could show way forward for preservation, REDD

2011-12-01T18:59:00Z

A new initiative to place community mapping of central African rainforests online could prove key to local rights in the region, says the UK-based NGO Rainforest Foundation. Working with forest communities in five African countries, Rainforest Foundation has helped create digital maps of local forests, including use areas, parks, and threats such as logging and mining. The website, MappingForRights.org, includes interactive maps, photos, and video.

Interview with conservation legend, Richard Leakey

2011-11-28T19:06:00Z

Following in his family's footsteps, Dr. Richard Leakey, is considered the heir to the scientific legacy of his parents, Louis and Mary Leakey, icons in the field of paleoanthropology. Dr Richard Leakey has been credited with some of the field's most successful paleoanthropologic finds, including a near complete, groundbreaking, Homo Erectus fossil dubbed 'Turkana Boy'. The scientific contributions of the Leakey family have reshaped our views of the origins of mankind and shed new light on the history and shared ties of the human family.

Giant rat plays big ecological role in dispersing seeds

2011-11-16T15:38:00Z

Rats are rarely thought of as heroes. In fact, in many parts of the world they are despised, while in others they serve largely as food. But, scientists are now discovering that many tropical forest rodents, including rats, serve as heroic seed dispersers, i.e. eating fruits and nuts, and carrying seeds far from the parent tree, giving a chance to a new sapling. While this has been documented with tropical rodents in South America like agoutis and acouchis, a new study in Biotropica documents the first successful seed dispersal by an African rodent: the Kivu giant pouched rat (Cricetomys kivuensis), one of four species of giant African rats.

Entertainment media skews public perception of chimpanzees in the wild

2011-11-14T21:36:00Z

You've probably seen them: the TV ads showing chimpanzees wearing suits, driving cars, or smoking cigars. These ads may tickle our funny bone, but they warp our perceptions of how chimpanzees are faring in the wild, researchers at Duke University have found. The study, published October 12 in the journal PLoS ONE, examined whether watching commercials featuring chimpanzees influenced people's understanding of their endangered status.

Critically Endangered lemurs disperse seeds, store carbon

2011-11-13T18:51:00Z

Many tropical plants depend on other species to carry their progeny far-and-wide. Scientists are just beginning to unravel this phenomenon, known as seed dispersal, which is instrumental in supporting the diversity and richness of tropical forests. Researchers have identified a number of animal seed dispersers including birds, rodents, monkeys, elephants, and even fish. Now a new study in the Journal of Tropical Ecology adds another seed disperser to that list: the Critically Endangered black-and-white ruffed lemur (Varecia variegata). Capable of dispersing big tree species, the black-and-white ruffed lemur may even play a big role in carbon sequestration.

A final farewell: the Western Black Rhino goes extinct

2011-11-12T20:19:00Z

The western black rhinoceros (Diceros bicornis longipes) roams the woodlands of Africa no more. The rhino, one of four sub-species of black rhino, was declared extinct this week by the IUCN, five years after the last extensive survey of its habitat in Cameroon. The rhino becomes the second declared extinct this year. All rhinos are threatened by the rhino horn trade.

African cattle benefit from socializing with wild grazers during the wet season

2011-11-08T05:21:00Z

Mingling with wild grazers, such as zebra, is better for cattle than dining alone—during the wet season, at least—according to researchers in Kenya. Their new study crumbles the longstanding assumption that social grazing always leads to food fights. Kenya’s wildlife population is in a critical decline, partly due to kill-offs by ranchers who see zebra, wildebeest, antelope and other grazers strictly as competition for their cattle. But scientists at the Mpala Research Center in central Kenya suspected there might be natural accords between grazers.

Animal picture of the day: crowned lemur and baby

The list includes completed dams, one currently under construction, and ones in initial planning stages.

South Africa hits record poaching of rhinos—again

2011-11-03T16:53:00Z

Two months before the end of the year, the number of rhinos killed for their horns in South Africa has surpassed last year's breaking record, reports conservation organizations WWF and TRAFFIC. So far, 341 rhinos have been lost to poaching this year; while last year saw a total record of 333. The news follows last week's announcement that the Vietnamese rhino (Rhinoceros sondaicus annamiticus), a subspecies of the Javan rhino, has gone extinct—the last individual killed by a poachers' bullet. Rhinos are killed for their horns which are used in traditional Chinese medicine, even though numerous studies have shown there is no medicinal benefit to consuming rhino horn.

Saving Ghana's vanishing frogs

2011-11-02T18:54:00Z

Frogs need all the help they can get. With the IUCN Red List estimating that 41 percent of amphibians are endangered, frogs are currently the world's most imperiled animal family. Scientists estimate that around 200 amphibian species have been lost to extinction in recent decades to habitat loss, pollution, and a devastating fungal disease. Yet as the frog emergency worsens, there have been positive movements in conservation. The most recent comes from the small West African country of Ghana. Partnering with the enthusiastic US-based organization, SAVE THE FROGS!, two Ghanaian herpetologists, Gilbert Baase Adum and Caleb Ofori, have started a sister branch in their country: SAVE THE FROGS! Ghana.

Climate change already worsening weird, deadly, and expensive weather

2011-11-02T16:41:00Z

Unprecedented flooding in Thailand, torrential rains pummeling El Salvador, long-term and beyond-extreme drought in Texas, killer snowstorm in the eastern US—and that's just the last month or so. Extreme weather worldwide appears to be both increasing in frequency and intensity, and a new report from the Intergovernmental Panel on Climate Change (IPCC) connects the dots between wilder weather patterns and global climate change.

Unsung heroes: the life of a wildlife ranger in the Congo

2011-11-01T16:25:00Z

The effort to save wildlife from destruction worldwide has many heroes. Some receive accolades for their work, but others live in obscurity, doing good—sometimes even dangerous—work everyday with little recognition. These are not scientists or big-name conservationists, but wildlife rangers, NGO staff members, and low level officials. One of these conservation heroes is Bunda Bokitsi, chief guard of the Etate Patrol Post for Salonga National Park in the Democratic Republic of the Congo. In a nation known for a prolonged civil war, desperate poverty, and corruption—as well as an astounding natural heritage—Bunda Bokitsi works everyday to secure Salonga National Park from poachers, bushmeat hunters, and trappers.

Illuminating Africa's most obscure cat

2011-10-18T19:57:00Z

Africa is known as the continent of big cats: cheetahs, leopards, and of course, the king of them all, lions. Even servals and caracals are relatively well-known by the public. Still, few people realize that Africa is home to a number of smaller wild cat species, such as the black-footed cat and the African wild cat. But the least known feline on the continent is actually a cryptic predator that inhabits the rainforest of the Congo and West Africa. "The African golden cat has dominated my thoughts and energy for over a year and a half now. When carrying out a study like this one, you find yourself trying to think like your study animal," Laila Bahaa-el-din, University of Kwazulu Natal graduate student, told mongabay.com in a recent interview.

Fertilizer trees boost yields in Africa

2011-10-16T17:35:00Z

Fertilizer trees—which fix nitrogen in the soil—have improved crops yields in five African countries, according to a new study in the International Journal of Agricultural Sustainability. In some cases yields have doubled with the simple addition of nitrogen-soaking trees. The research found that fertilizer trees could play a role in alleviating hunger on the continent while improving environmental conditions.

Poor in Madagascar see fish plundered for foreign consumption

2011-10-11T17:25:00Z

A new study warns that overfishing could exacerbate poverty and political stability in one of the world's poorest nations: Madagascar. According to the recent study by the University of British Columbia's Sea Around Us Project and Malagasy NGO Blue Ventures, fish catches in the African island-nation from 1950 to 2008 are actually double the official numbers, with foreign wealthy nations currently taking half the haul.

Tea Party rallies in favor of Gibson Guitar, ignores reasons instrument-maker is under investigation

2011-10-10T13:23:00Z

This weekend around 500 people showed up for a rally and concert in Nashville, Tennessee. The rally was in support of Gibson Guitars, a US-company currently under investigation for allegedly importing illegally logged wood into the country, an action that breaks a recent bipartisan amendment to the Lacey Act. While the Tea Party-affiliated groups that held the rally were expressing frustration with perceived over-regulation by the federal government, the issue at stake—a global effort to help stem illegal logging—was actually overlooked by the organizers.

World's newest nation faces prospect of famine

2011-10-06T18:32:00Z

As East Africa reels from a devastating famine, which is hitting Somalia the hardest, there are new fears that another African nation could soon slip into a similar situation. On July 9th of this year, South Sudan became the world's newest nation; however a few months later drought, conflict, refugees, and rising food prices could push the eastern region of South Sudan into a famine, warned officials from the fledgling nation yesterday.

Tea party versus Madagascar's forests

2011-10-02T21:13:00Z

The Tea Party and the African island-nation of Madagascar are having dueling concerts over the issue of illegal logging, reports the Associated Press. A concert in Madagascar over the weekend was meant to highlight the problem of illegal deforestation in one of the world's poorest countries. Meanwhile the Tea Party is holding a rally and concert on October 8th to support Gibson Guitar, a musical instruments company currently under investigation for breaking US law by allegedly purchasing illegally logged wood products from Madagascar.

Madagascar asks CITES to regulate rosewood and ebony

2011-09-29T21:36:00Z

Following a logging crisis in 2009 where a number of Madagascar's remaining forests were illegally cut, the African nation has turned to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to help regulate 91 species of rosewood and ebony. "Regulating trade in these high-value timber species under CITES will help ensure that the benefits of trade flow to local people and it will also serve the global community by helping conserve these species, which will be to the benefit of entire ecosystems."

Forest carbon projects rake in $178 million in 2010

2011-09-29T17:54:00Z

Investors funneled $178 million into forest carbon projects intended to mitigate global climate change last year, according to a new report by Forest Trends' Ecosystem Marketplace. By trading a record 30.1 million tons of carbon dioxide equivalent (MtC02e), the market saw a 48 percent rise over 2009—including a rise in private investors over non-profits as well as greater support for the global program Reduced Emissions from Deforestation and forest Degradation (REDD)—shows that the burgeoning market may be beginning to make good on its promise to provide funds to save forests for their ecosystem services with an initial focus on carbon.
