Video: scientists capture giant spider eating an opossum

[1,416,771 pageviews]

[Rhett A. Butler on 2 March 2019] Writing in the February 28th issue of the journal Amphibian & Reptile Conservation, a team of scientists describe several rarely observed cases of invertebrates eating various vertebrates, including frogs, lizards, snakes, and even a mammal — a mouse opossum. It was the first time, researchers have documented a giant spider eating an opossum in the Amazon rainforest.

The extinction clock ticks for the little-known Philippine pangolin

[675,449 pageviews]

[Imelda Abano on 22 April 2019] With the Palawan pangolin’s population decimated by poaching and its habitat lost to urban expansion, scientists and conservationists are in a race against time to save and document everything about this forest dweller.

All that glitters: Cameras spot Asian golden cat in more than one shade

[304,912 pageviews]

[Shreya Dasgupta on 20 June 2019] Cameras placed across the Dibang Valley in the northeastern Indian state of Arunachal Pradesh have captured Asian golden cats with six different coat colors. These include five colors previously described from different parts of the cat’s distribution across Asia — golden, gray, cinnamon, melanistic (black) and ocelot (spotted) — as well as a previously unrecorded dark pattern of tightly spaced rosettes.

The wolf of Bangladesh: A true story

[297,673 pageviews]

[Jeremy Hance on 7 August 2019] The last wolf in Bangladesh was seen in 1949 – until this year. The wolf, an adult male, was killed by local villagers in the Sundarbans, a suboptimal habitat for wolves. But could there be more wolves in the Sundarbans?

Women from the Xingu Territory unite against threats from Bolsonaro administration

[262,733 pageviews]

[Maria Fernanda Ribeiro on 18 December 2019] In May 2019, some 200 representatives from 16 different ethnicities gathered for the first women’s summit in the Xingu Indigenous Territory’s in the state of Mato Grosso. Feeling under threat from policies regarding native peoples under the Jair Bolsonaro administration and tired of their community roles being restricted to domestic tasks, the women met to discuss ways to occupy leadership roles alongside men and, in doing so, gain strength to protect their territory.

Can jaguar tourism save Bolivia’s fast dwindling forests?

[255,742 pageviews]

[Rhett A. Butler on 7 March 2019] Few countries in the tropics have seen trees chopped down as quickly as Bolivia did between 2001 and 2017. Within Bolivia, nearly two-thirds of that loss occurred in just a single state—Santa Cruz—as agribusiness activity, namely cattle ranching and soy farming, ramped up. This loss has greatly reduced the extent of habitat for some of Bolivia’s best known species, including the largest land predator in the Americas, the jaguar. On top of habitat loss, jaguars in Santa Cruz are both persecuted by landowners who see them as a danger to livestock, and targeted in a lucrative new trade in their parts, including teeth and bones. Duston Larsen, the owner of San Miguelito Ranch, is working to reverse that trend by upending the perception that jaguars necessarily need be the enemy of ranchers.

Video: Pango-Cam offers amazing and unique view of pangolin behavior

[250,717 pageviews]

[Erik Hoffner on 16 September 2019] The Pango-Cam is a first-of-its-kind camera setup attached to a black-bellied pangolin’s back to provide unique footage of the animal’s behavior. A collaboration between filmmaker Katie Schuler, pangolin biologist Matthew Shirley, and National Geographic’s Exploration Technology Lab, the team recently recorded excellent footage in Nigeria. Pangolins are poorly understood and are also under grave threat from the illegal wildlife trade, so it’s hoped the Pango-Cam can improve awareness and knowledge of the secretive animals.

New film reveals at-risk ‘uncontacted’ Awa tribe in Brazilian Amazon

[243,616 pageviews]

[Karla Mendes on 1 August 2019] A documentary film released over the summer includes footage of an uncontacted indigenous group known as the Awá Guajá, hunter-gatherers described by NGO Survival International as the most threatened tribe on the planet. The indigenous group lives in Brazil’s Amazon rainforest in Northeast Maranhão state. The footage was captured by chance by cameraman Flay Guajajara, a member of the Mídia Índia (a collective of indigenous communicators of various ethnicities) when he and other Guajajara Indians were on a hunting trip in the Araribóia reserve, one of the country’s most threatened indigenous territories.

Why is Europe rewilding with water buffalo?

[214,089 pageviews]

[Jeremy Hance on 21 October 2019] Conservationists have released 18 water buffalo onto Ermakov Island in the Danube, in the first ever such rewilding project in Ukraine. The water buffalo were gifted by a German-born naturalist-cum-farmer, Michel Jacobs, who has taken on a mission of saving the Carpathian’s distinct water buffalo. Researchers believe the water buffalo will bring new richness and diversity to the Danube by acting as ecosystem engineers.

In Ethiopia, women and faith drive effort to restore biodiversity

[161,871 pageviews]

[Christopher Lett on 20 March 2019] In Addis Ababa, approximately 35 percent of the household fuelwood – mainly eucalyptus – is systematically gathered from the Entoto Mountains just outside the city. Ethiopia historically planted large areas with fast-growing eucalyptus, a non-native species, to meet the demand for fuelwood. But the trees’ water-hogging nature has had a destructive impact on the land. There are efforts to reforest areas with native species, supported by the Ethiopian Orthodox Church, which has a tradition of maintaining tree gardens throughout the country.

Madagascar: Opaque foreign fisheries deals leave empty nets at home

[148,179 pageviews]

[Edward Carver on 9 October 2019] Malagasy fishers blame shrimp trawlers that ply coastal waters for their declining catches. However, the bulk of industrial fishing in Madagascar’s waters takes place far from shore and out of view. It’s conducted by foreign fishing fleets working under agreements that critics say lack transparency. Conservationists argue that these foreign vessels are also depleting the country’s fish stocks and marine ecosystems.

Belize to protect critical wildlife corridor that’s home to jaguars and more

[147,104 pageviews]

[Shreya Dasgupta on 24 June 2019] The government of Belize has approved a proposal to protect the Maya Forest Corridor, a key stretch of jungle linking some of the region’s largest wilderness areas. Once the corridor is secured, it will create the largest contiguous block of forest in Central America, experts say. The Maya Forest Corridor is home to iconic animals like the jaguar; the critically endangered Central American river turtle; the endangered Central American spider monkey or Geoffroy’s spider monkey; and the endangered Baird’s tapir. There is, however, a lot of work to be done before the Maya Forest Corridor gains official legal protection, including securing key privately owned patches of forest in the area.

Documentary seeks to tip the scales against illegal pangolin trafficking

[143,592 pageviews]

[Erna Curry on 27 June 2019] A film released over the summer aims to raise awareness and strengthen protection and conservation of pangolins. Hunting and trafficking of these animals in Africa has sharply intensified to meet demand from Asia in recent years. Pangolins have historically been used for traditional medicine, decoration and gift-giving across Africa.

These rare pigs can dig it. With a tool, that is. And moonwalk too

[142,666 pageviews]

[Leilani Chavez on 18 October 2019] A viral video shows a family of Visayan warty pigs (Sus cebifrons) using a piece of tree bark or branch to build a nest at a zoo in Paris. Tool use has been widely reported among vertebrates, particularly primates, but this is the first published study and first recorded video of pigs using tools. The study suggests that using a stick is a socially learned behavior, and expands the possibility of tool use and social learning among pig species.

Agriculture, mining, hunting push critically endangered gorillas to the brink

[140,594 pageviews]

[Rachel Fritts on 16 July 2019] Maiko National Park is one of the most logistically challenging parks in the DRC and one of the most biodiverse. It is one of just two national parks in the world known to contain Grauer’s gorilla, a highly endangered and poorly understood eastern gorilla subspecies, and is also home to the endemic okapi and Congo peafowl, as well as forest elephants, leopards, chimpanzees, and giant pangolins. The most major threat to gorillas and other wildlife in Maiko is the bushmeat trade, but this is significantly exacerbated by another threat: artisanal mining. The Second Congo War coincided with a demand spike for a mineral called coltan that forms an essential component of all phones, computers, solar panels, and other electronics. Outside of the park, however, there is another threat to wildlife: increasing pressure from rising populations.

Amid aquaculture boom, report guides investors toward sustainability

[139,108 pageviews]

[Max Radwin on 8 May 2019] More than half of all seafood now comes from farms, and that percentage is projected to rise. However, environmental problems currently bedevil the aquaculture industry, and a consensus on the most sustainable practices has yet to emerge. A report released May 8, 2019 aims to guide the private sector, NGOs and policymakers toward better aquaculture strategies. In place of business-as-usual practices, the report advocates for three alternatives: a land-based aquaculture strategy called recirculating aquaculture systems; offshore fish farms; and seaweed and shellfish farming.

A snapshot of camera traps reveals user frustrations and hopes

[131,521 pageviews]

[Sue Palminteri (1965-2019) on 14 February 2019] A team of camera trapping experts surveyed researchers and conservation professionals to identify limitations to their successful use of remote cameras, assess their wish list of technological developments, and predict what next-generation camera trapping will look like. Their study revealed that cost, theft, vulnerability of the cameras to environmental conditions, and several ongoing technical issues may be limiting the effectiveness of this popular technology in providing the utility the users seek. The survey respondents offered numerous predictions for next-generation camera trapping, including solar and lithium-ion power sources, a wider range of sensors, and software-driven automation.

Habitat loss, pigs, disease: U.S. salamanders face a ‘tough situation’

[128,134 pageviews]

[Morgan Erickson-Davis on 3 January 2019] A pandemic is on the horizon. A fungal pathogen called Batrachochytrium salamandrivorans (Bsal) almost completely wiped out several fire salamander populations in Europe and biologists think it may be only a matter of time until it gets to North America. North America is the world’s hotspot of salamander diversity, with around half the world’s species.

The Pan Borneo Highway on a collision course with elephants

[119,088 pageviews]

[John C. Cannon on 28 August 2019] Out of the controversy surrounding the Pan Borneo Highway and its potential impacts on the environment has arisen a movement to bring conservationists, scientists and planners together to develop a plan “to maximize benefits and reduce risks” to the environment from the road’s construction.

Meet the new species of venomous pit viper described from India

[111,009 pageviews]

[Shreya Dasgupta on 9 May 2019] Wildlife researcher Rohan Pandit and his teammate Wangchu Phiang first stumbled upon the new-to-science pit viper species in May 2016 while surveying biodiversity in the state of Arunachal Pradesh in India. Researchers have NOW described this species and named it Trimeresurus arunachalensis, or Arunachal pit viper.
