How do we save the world's vanishing old-growth forests?|
(08/26/2014) There's nothing in the world like a primary forest, which has never been industrially logged or cleared by humans. They are often described as cathedral-like, due to pillar-like trees and carpet-like undergrowth. Yet, the world's primary forests—also known as old-growth forests—are falling every year, and policy-makers are not doing enough to stop it.
Scientists honor missing activist by naming a spider after him
(08/25/2014) Swiss researchers have honored the memory of a missing indigenous peoples activist by naming an undescribed species of spider after him, reports the Bruno Manser Fund, the group he founded.
Scientists name new endangered species after the company that will decide its fate
(08/24/2014) Scientists have discovered a new snail species near a cement quarry in Malaysia, which as far as they know lives nowhere else in the world. It lives on a limestone hill called Kanthan given as a concession to an international company Lafarge. The cement producer quarries the hill for raw materials. As a result, the scientists have named the species after the company that will decide if it goes extinct.
Selective logging hurts rainforest frogs
(08/21/2014) Selective logging in India's Western Ghats forests continues to affect frogs decades after harvesting ended, finds a new study published in Biotropica. The research assessed frog communities in logged and unlogged forests in Kalakad Mundanthurai Tiger Reserve and found that unlogged forests had twice the density of frogs as areas logged in the 1970s.
Why conservationists need a little hope: saving themselves from becoming the most depressing scientists on the planet
(08/19/2014) Here's a challenge: take a conservationist out for a drink and ask them about their work. Nine times out of ten—or possibly more—you'll walk away feeling frustrated, despondent, and utterly hopeless. Yet a few conservation scientist are not just trying to save species from extinction, but also working to save their field—their life's work—from slipping into total despair.
An untapped resource: new study finds local people may trump scientists at biodiversity surveys
(08/12/2014) Figuring out what species live in a given area is important to the determination of its conservation importance. Traditionally, these biodiversity assessments have been done directly by scientists via surveys, which can be very time-intensive and expensive. However, a new study found that interviewing people in local communities who are familiar with the species of their regions could be just as effective – and much cheaper.
Scientists catalog the world's 10,000th reptile
(08/04/2014) As of this year, scientists have named and described over 10,000 reptiles, marking a new milestone in cataloging one of the most diverse vertebrate groups. Last week, the Reptile Database, an online catalog of all the world's living reptiles, announced it had passed 10,000 species.
Ecologists are underestimating the impacts of rainforest logging
(07/31/2014) Ecologists may be underestimating the impact of logging in old-growth tropical forests by failing to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues a paper published today in the journal Current Biology. The study, led by Zuzana Burivalova of ETH Zurich, is based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests.
87 new bird species considered threatened with extinction
(07/29/2014) Scientists have added 361 new bird species to the IUCN Red List following a major taxonomic review of non-passerine birds, i.e. non-perching or non-songbirds. Worryingly, 87 of these new birds are threatened with extinction, a percentage nearly double the overall threatened percentage for all birds, which currently sits at 13 percent.
Deforestation ramping up in Yasuni as Ecuador sets to open up national park to drilling
(07/29/2014) Yasuni National park has been in the conservation spotlight in recent years, with oil drilling threatening the forests and wildlife of this biodiversity hotspot. Recently, disturbance in the park may have ramped up, with satellite data showing a significant increase in deforestation alerts within Yasuni National Park since 2011.
It's not just extinction: meet defaunation
(07/24/2014) Get ready to learn a new word: defaunation. Fauna is the total collection of animals—both in terms of species diversity and abundance—in a given area. So, defaunation, much like deforestation, means the loss of animals in all its myriad forms, including extinction, extirpation, or population declines.
Surprising habitat: camera traps reveal high mammal diversity in forest patches within oil palm plantations
(07/21/2014) After more than four and a half years of camera trap footage, the results are encouraging: 36 mammal species, of which more than half are legally protected, are prospering in this most surprising of spots: an oil palm plantation in the province of East Kalimantan in Indonesian Borneo.
Too much of a good thing: fertilizer 'one of the three major drivers of biodiversity loss this century'
(07/14/2014) The world’s grasslands are being destabilized by fertilization, according to a paper recently published in the journal Nature. In a study of 41 grassland communities on five continents, researchers found that the presence of fertilizer weakened grassland species diversity.
Only 15 percent of world's biodiversity hotspots left intact
(07/14/2014) The world's 35 biodiversity hotspots—which harbor 75 percent of the planet's endangered land vertebrates—are in more trouble than expected, according to a sobering new analysis of remaining primary vegetation. In all less than 15 percent of natural intact vegetation is left in the these hotspots, which include well-known jewels such as Madagascar, the tropical Andes, and Sundaland.
Downturn in shade-grown coffee putting forests, wildlife, people at risk
(07/11/2014) Growing coffee in the shade of forests allows native vegetation to persist, thereby reducing the impact of agriculture on the natural landscape. While production of shade-grown coffee surged in recent decades, it is now experiencing a decline. A recent study analyzed the situation, finding that the growth of consumer demand and changes in coffee agronomy has caused coffee production and management to change drastically.
Booming populations, rising economies, threatened biodiversity: the tropics will never be the same
(07/07/2014) For those living either north or south of the tropics, images of this green ring around the Earth's equator often include verdant rainforests, exotic animals, and unchanging weather; but they may also be of entrenched poverty, unstable governments, and appalling environmental destruction. A massive new report, The State of the Tropics, however, finds that the truth is far more complicated.
Is REDD+ bad for wildlife? New study says lowland forest protection bias unfair, urges change
(06/27/2014) A study published this week found tree cover does not necessarily correlate with habitat importance. It suggests that using such a metric may be leading to false assumptions of habitat importance, and that REDD+ and other carbon-centric conservation programs may actually be propelling some species towards extinction.
Study finds tiny cloud forests have big biodiversity
(06/24/2014) Tropical cloud forests are situated in mountains and are characterized by the frequent presence of low-level clouds. Scientists have always regarded them as having high biodiversity, but a recent study adds a new dimension: it found cloud forests contain a significant and surprising array of tree and bromeliad species, even when they are relatively small.
Broken promises no more? Signs Sabah may finally uphold commitment on wildlife corridors
(06/23/2014) Five years ago an unlikely meeting was held in the Malaysian state of Sabah to discuss how to save wildlife amid worsening forest fragmentation. Although the meeting brought together longtime adversaries—conservationists and the palm oil industry—it appeared at the time to build new relationships and even point toward a way forward for Sabah's embattled forests.
Scientists discover carnivorous water rat in Indonesia, good example of convergent evolution
(06/19/2014) Researchers have discovered a new carnivorous water rat on the island of Sulawesi that's so unique it represents an entirely new genus. They believe many more new rodent species await discovery in this relatively undisturbed part of Indonesia, but mining and other types of development may threaten vital habitat before it’s even surveyed.
Fly and wasp biodiversity in Peru linked to strange defense strategy
(06/18/2014) Entomologists working in Peru have revealed new and unprecedented layers of diversity amongst wasps and flies. The paper, published in the journal Science, also describes a unique phenomenon in which flies actually fight back and kill predatory parasitic wasps.
More is better: high bee biodiversity boosts crop yields
(06/12/2014) Scientists have discovered that blueberry plants visited by more diverse bee species increased their seed number, berry size and fruit set, and quickened their ripening time. They hope their findings encourage farmers to help support local wild bee communities.
Oil overthrow: Soco to suspend operations in Virunga National Park after sustained campaign by WWF
(06/11/2014) In a surprise announcement, British oil company Soco International has said it will suspend exploratory operations in Virunga National Park, home to half the world's Critically Endangered mountain gorillas as well as thousands of other species. The announcement follows several years of campaigning from conservation groups led by WWF.
After throwing out referendum, Ecuador approves oil drilling in Yasuni's embattled heart
(06/02/2014) By 2016, oil drilling will begin in what scientists believe is the most biodiverse place on the planet: remote Yasuni National Park. Late last month, Ecuador announced it had approved permits for oil drilling in Yasuni's Ishpingo-Tambococha-Tiputinin (ITT) block, an untouched swathe of primary rainforest covering around 100,000 hectares or about 10 percent of the park.
Of jaguars and loggers: new film to showcase one of the least-known regions in the deep Amazon
(06/02/2014) In August, three young filmmakers will go on the expedition of a lifetime. They plan to spend six months filming in one of the most remote, most spectacular, and most endangered ecosystems on the planet: the Las Piedras River system. This unprotected swathe of Amazon jungle contains massive anacondas, prowling jaguars, and even uncontacted indigenous people.
Extinction rates are 1,000x the background rate, but it's not all gloomy
(05/29/2014) Current extinction rates are at the high end of past predictions, according to a new paper published today in Science, however conservation efforts combined with new technologies could make a big difference. New research led by Stuart Pimm of Duke University argues that humans have pushed the current extinction rate to 1,000 times the historical rate.

(05/22/2014) Out of around 18,000 new species described and named last year, scientists have highlighted ten in an effort to raise awareness about the imperiled biodiversity around us. Each species—from a teddy-bear-like carnivore in the Andes to a microbe that survives clean rooms where spaceships are built—stands out from the crowd for one reason or another.
'Simmering conflict': the delicate balancing act of protecting India's wilderness
(05/13/2014) The Western Ghats of southern India, one of the world’s top biodiversity hotspots, is a 1600-kilometer (1000-mile) mountain chain that runs parallel to the western coast of the Indian subcontinent. It traverses six states and is home to as many as 250 million people. In an interview with mongabay.com, M.D. Madhusudan of the Nature Conservation Foundation discusses the importance and challenges of establishing protected areas in India.
Not all used up: why conserving selectively logged forests is important
(05/02/2014) Tropical forests, which provide rich biodiversity, vital carbon storage, and essential medicines, are being damaged and destroyed at a rapid rate worldwide. Loggers especially target old-growth forests for selective harvesting of their valuable timber. But while selectively logged forests are indeed degraded, these disturbed forests are valuable ecosystems for many species, with higher biological productivity than previously thought, and merit increased conservation attention, argues a new paper published in Frontiers in Ecology and the Environment
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.
'Better late than never': Myanmar bans timber exports to save remaining forests
(04/24/2014) Myanmar contains some of Asia's largest forests, but has been losing them at a rapid pace during the last two decades as logging companies emptied woodlands to meet the demands of the lumber industry. In an effort to save its disappearing forests, Myanmar implemented a ban on raw timber exports, effective March 31, 2014. However, the ban affects only raw timber exports, not milled lumber, throwing into doubt its ability to adequately protect Myanmar's forests.
Long lives, big impacts: human life expectancy linked to extinctions
(04/15/2014) Since the arrival of Homo sapiens, other species have been going extinct at an unprecedented rate. Most scientists now agree that extinction rates are between 100 and 1000 times greater than before humans existed. Working out what is driving these extinctions is fiendishly complicated, but a new study suggests that human life expectancy may be partly to blame.
Life finds a way: the surprising biodiversity of cities
(04/11/2014) In the largest global assessment of urban biodiversity to date, researchers examined the biodiversity of urban areas and found that cities are home to a surprising number of species. The study underlines the conservation importance of preserving and creating green spaces when it comes to urban planning.
Giant ibis, little dodo, and the kakapo: meet the 100 weirdest and most endangered birds
(04/10/2014) The comic dodo, the stately great auk, the passenger pigeon blotting out the skies: human kind has wiped out nearly 200 species of birds in the last five hundred years. Now, if we don't act soon we'll add many new ones to the list: birds such as the giant ibis, the plains-wanderer, and the crow honeyeater. And these are just a few of the species that appear today on the long-awaited EDGE list.
Next big idea in forest conservation? Connecting deforestation to disease
(04/03/2014) Thomas Gillespie is concerned with the connections between conservation and disease, with a particular emphasis on primates. Much of his research examines the places where humans and animals are at a high risk of exchanging pathogens, and how human-caused disturbances, such as deforestation, can change disease dynamics and impacts.
Brief lives linked to Amazon biodiversity
(03/31/2014) The South American Amazon rainforest is renowned for being one of the most biodiverse ecosystems on the planet, boasting an estimated 16,000 different tree species. However, the distribution of these diverse tree species is curiously uneven. What is the reason behind this irregular diversity? According to a new study, the answer lies within short durations between tree generations.
Apocalypse now? Climate change already damaging agriculture, acidifying seas, and worsening extreme weather
(03/31/2014) It's not just melting glaciers and bizarrely-early Springs anymore; climate change is impacting every facet of human civilization from our ability to grow enough crops to our ability to get along with each other, according to a new 2,300-page report from the Intergovernmental Panel on Climate Change (IPCC). The massive report states definitively that climate change is already affecting human societies on every continent.
Revealed for the first time: the surprising biodiversity of algae 'reefs'
(03/28/2014) Most people are familiar with coral reefs, but very few have ever heard of their algal equivalent – rhodolith beds. Yet, these structures provide crucial habitat for many marine species. In the first study of its kind, published in mongabay.com’s Tropical Conservation Science, researchers unveil just how important these beds are for bottom-dwelling organisms, and the species that depend on them.
