Researchers are using acoustic monitoring to tune into gunshots and track a most deadly predator – Africa’s wildlife poachers.
Cameroon’s Korup National Park is home to elephants, chimpanzees, red colobus monkeys, drill, and a myriad of noisy species, whose squawks, squeals and howls fill the forest air. For more than two years, twelve acoustic monitors were deployed there and recorded every sound covering a 54 square kilometer (21 square mile) area of protected tropical forest.
They were tuned to listen around the clock for just one sound: gunshots.
“Our ultimate goal is to improve the effectiveness of anti-poaching patrols in African tropical forest protected areas,” Joshua Linder, one of the lead scientists working on the acoustic monitoring project, told Mongabay.

Climate change health effects are wide ranging and include negative impacts on air quality, mental health, nutrition, and insect and microbe transmitted diseases.
- A Climate and Health Assessment presented at the White House by the US Global Change Research Program revealed wide-ranging climate change health impacts.
- Every American is vulnerable, but low income people, certain ethnicities, Indigenous people, the young, elderly, and pregnant women are disproportionately at risk.
- The report is meant to help policymakers generate and implement a proactive response to the many escalating and evolving health impacts due to climate change.

Scientists have discovered at least 500 Critically Endangered grey-shanked doucs in Vietnam — their only home — boosting species estimates to up to 1,500 animals

Grey-shanked doucs live in the forest canopy of the Central Highlands of Vietnam. Their numbers have been severely reduced by habitat loss and fragmentation, along with hunting for food and the pet trade.
Fauna & Flora International (FFI) researchers located the 500+ animals in several subpopulations within the Kon Tum forest, which provides important connectivity to protected areas to the south and north, and across the border into Cambodia.
FFI Vietnam is now developing a conservation strategy which may include ecotourism and forest patrols for the newly discovered population. Vietnam is home to 11 Critically Endangered primate species, and a priority for primate conservation in Southeast Asia and the world.

The long-limbed, canopy-swinging, duet-singing gibbons of Southeast Asia are under threat as industrial agriculture eats into their forest habitat. Palm oil plantation expansion is famously bad news for all sorts of wildlife, as are the new sugar and rubber plantations also driving deforestation across the region. But gibbon species are especially vulnerable: the cutting of trees makes their favored high-flying locomotion impossible — a potentially fatal plight for this overlooked great ape.
Finding the balance between economic development, industrial agricultural production, and great ape conservation is an urgent challenge facing governments and conservation organizations in many parts of Asia and Africa, as highlighted by the recent report, “State of the Apes: Industrial Agriculture and Ape Conservation”.
One such struggle is playing out in the Northern Plains of Cambodia, where the Pileated Gibbon (Hylobates pileatus) is the ape at risk. There, a mixture of evergreen and deciduous forest is home to not only H. pileatus, but a host of other species pressured by encroaching agribusiness. This besieged region includes one of the largest remnants of deciduous dipterocarp forest — dubbed the Central Indochina Dry Forest ecoregion — that once extended across much of Thailand, Vietnam, Laos and Cambodia.
WCS is working with local communities and government ministries to conserve the gibbons. You can read the full article to learn more about their gibbon project on Mongabay.

My latest piece for Mongabay looks at some of the threats facing the Amazon’s freshwater ecosystems, and at how a fragmented protected area network and policy framework – based on terrestrial ecosystems – is failing to protect the connectivity of the freshwater world. As multiple impacts interact with each other the functioning of the whole ecosystem is under threat. You can read the full article here.
A little while ago I wrote about the plight of Amazon river dolphins in the face of dam-building across the region. Here’s the opening few lines, but to read the whole piece please follow the link to the original on Mongabay. A National Geographic photographer kindly let us use some of his pictures, so it is worth a look!
A dam-building boom is underway in the Amazon. More than 400 hydroelectric dams are in operation, being built, or planned for the river’s headwaters and basin. Scientists know that tropical dams disrupt water flow and nutrient deposition, with negative consequences for aquatic animals, especially migratory species. But little detailed knowledge exists as to the impacts of dams on specific species, or as to the best mitigations to prevent harm.
A recent study that tries to fill in that knowledge gap zeroes in on Brazil’s river dolphins. It found that as many as 26 dams could negatively impact dolphin populations and their prey.
The research, led by Dr Claryana Araújo of the Federal University of Goiás, Brazil, focused on two freshwater species: the Amazon River Dolphin, or boto (Inia geoffrensis), which is sometimes famously pink; and the Tucuxi (Sotalia fluviatilis).
The river dolphins of South America are charismatic emblems of rainforest biodiversity, and have captured the public imagination. Swimming in rivers, lagoons, and among submerged tree trunks in flooded forests to chase down prey, they can be found as far inland as the upper reaches of Amazonian tributaries, more than 2,600 kilometers (1,615 miles) from the Atlantic Ocean.
