Swedish experiment shows the notoriously brilliant bird has capacity to think ahead, an ability previously documented only in humans and great apes

Scientists from Sweden say ravens are able to think about the future, showing a general planning ability previously documented only in people and great apes.

Researchers Can Kabadayi and Mathias Osvath, of Lund University, tested five captive ravens in two tasks they do not do in the wild: using tools and bartering with humans. The results were published on Thursday by the journal Science.

Highly collectable species, especially those that are rare and threatened, can potentially be put at risk from poaching if information describing where they can be found is published. But rather than withholding this information, as has been recently recommended, scientists should publish such information through secure data repositories so that this knowledge can continue to be used to help conserve and manage the world’s most threatened species.

Scientists are encouraged to publish data so their discoveries can be shared and scrutinised. However, a recent article has identified the risks of publishing the locations of rare, endangered or newly described species.

The example of the Chinese cave gecko shows that these concerns may be warranted. The species went extinct at the location where it was discovered, potentially at the hands of scientifically literate poachers.

But instead of withholding such information, we suggest (in a letter published today in Science) that scientists can publish sensitive data securely, while minimising the risk of misuse, by using one of a range of currently available tools.

A little knowledge

Typically, the problem for threatened species is not that too much information is available on their population and location, but rather quite the opposite. For example, in New South Wales more than 150 species have missed out on conservation funding because of a lack of such information.

On the flip side, there is little evidence that encouraging researchers to withhold this information will thwart people who are determined to find specific species. Collectors who specialise in highly collectable species can get location information from a variety of sources such as wildlife trade websites, pet and naturalist clubs, social media, and the popular press. This is despite the range of laws, regulations (such as scientific and collecting permits) and community reporting aimed at restricting the collection and trade of endangered species.

Many governments have implemented sensitive data policies to protect ecological and species data, based on their own lists of sensitive species. Many of these policies have been in place for almost a decade and have kept secure the locations of hundreds of highly collectable species such as Australia’s Wollemi pine.

These policies are practised by numerous data portals worldwide, including DataONE, South Africa’s National Biodiversity Institute, Australia’s Virtual Herbarium, Australia’s Department of Environment, the Global Biodiversity Information Facility, the Terrestrial Ecosystem Research Network, and the Atlas for Living Australia.

A wealth of advice is also available to researchers and data managers on how to manage sensitive species information, such as the guidance provided by Science International and the Australian National Data Service. Science journals also work closely with open data repositories to ensure that sensitive species information is securely published – see, for example, the policies of leading journals Science and Nature.

Information entropy - why it’s a good idea to publish data before they are lost in the mists of time. Michener (2006) Ecol. Informatics

One example of good data management is the AEKOS data portal run by Australia’s Terrestrial Ecosystem Research Network (TERN). AEKOS contains data from different government monitoring surveys covering almost 100,000 sites across the country. Its default position is to make ecological data and information freely available for land-management or wildlife research.

However, sensitive data are flagged during the early stages of the publishing process. The data are then secured in one of three ways:

• masking sensitive information by giving only approximate locations or non-specific species names

• making data available only after approval by the legal owners

• embargoing the data for a maximum of two years.

To ensure data trustworthiness, TERN’s data reviewers further check for any data sensitivities that may have been overlooked during submission.

What’s the alternative?

We recognise the importance of keeping the locations of highly collectable species secure, and the need for caution in publishing precise site locations. But despite recent concerns, the examples given above show how online scientific data publishing practices have sufficiently matured to minimise misuses such as illegal or excessive collection, disturbance risk, and landholder privacy issues.

The alternative is not to deposit these valuable data at all. But this risks the loss of vital knowledge in the quest to protect wildlife.

In tackling poaching, we should perhaps seek to motivate poachers to help protect our most endangered wildlife. Such tactics are thought by some to have contributed to the discovery of several endangered bird species populations, and potentially the recent rediscovery of the night parrot, after a century of elusiveness in Australia. If poachers are willing to turn gamekeeper, getting them to share their rare species knowledge securely would certainly improve conservation outcomes.

‘I’ll still be doing this on a mobility scooter,’ says one of 100 volunteers who survey national park’s 1,628 miles of paths

One of the many reasons Sally Williams loves the Yorkshire dales national park is because its dramatic landscape has been marked by centuries of human activity. “It’s not like you get in America – a huge area of undiscovered land that nobody has ever trodden on,” she says, standing near the entrance to an old limestone quarry. “It’s an area where people have lived and worked for centuries, and you can see the evidence of that all over the countryside.”

The 67-year-old former librarian is one of an army of nearly 100 volunteers who, every summer, undertake a survey of the park’s 1,628 miles (2,620km) of public rights of way. The volunteers, mainly local retirees, walk every single path and bridleway, ensuring that the park’s “infrastructure” – including its 5,665 gates, 4,862 stiles, 4,399 signposts and 1,054 bridges – is accessible, undamaged and safe.

EU asks court to protect one of Europe’s last primeval woodlands after the Polish government tripled logging operations at the Unesco world heritage site last year

Europe’s last major parcel of primeval woodland could be set for a reprieve after the EU asked the European court to authorise an immediate ban on logging in Poland’s Białowieża forest.

Around 80,000 cubic metres of forest have been cleared since the Polish government tripled logging operations around the Unesco world heritage site last year.

Falling battery costs to drive sales but European carmakers will lose out to rivals in the US and Asia, forecasts Dutch bank

All new cars sold in Europe will be electric within less than two decades, driven by government support, falling battery costs and economies of scale, a Dutch bank has predicted.

However, ING warned that with battery-powered vehicles accounting for 100% of registrations in 2035 across the continent, European carmakers would lose out to their rivals in the US and Asia who already lead on battery production.

In Guatemala, one of the world’s largest silver deposits reaps millions for its Canadian owners but for local farmers the price is their land and even their lives

Deep underground, buried in the lush hills of southern Guatemala, lies a veritable treasure trove: silver, tonnes of it, one of the largest deposits in the world.

But it’s above ground where the really dangerous activity goes on. On a dusty highway, about 50 peasant farmers stand praying in a circle, a makeshift roadblock intended to stop trucks reaching the mine. They have already been violently dispersed by police teargas. Now they fear the army might move in.

With one elephant killed every 25 minutes, the poaching crisis continues. But with the commitment and activism of a growing global network – dominated by women – laws and attitudes around the world are changing

If dedication and hard work were all it took, Maria Mossman would have saved every last elephant by now. Despite having two children, aged five and seven, and a part-time job for a large corporation, she also spends 35 to 40 hours a week as an unpaid activist. It was even more time when the children were younger. “I used to come home from work at about 4pm and then sit on my computer, networking with other groups and activists until two o’clock in the morning,” she recalls.

Mossman, 41, got heavily involved in elephant activism in 2013. As well as founding Action for Elephants UK (AFEUK), she’s one of the key organisers of the global elephant and rhino marches. “It’s really hard work,” she says. “Really stressful. Just before the marches you say: ‘We’re not going to do this again.’ And as soon as one is over you start planning the next one.”
