Anyone who has been outdoors in a populated area in the past month will be aware of the massive success of Pokémon GO, which has rocketed to the top of the gaming charts.

People have been avidly collecting Pokémon creatures in various media formats for two decades, so it was a logical move to use smartphone technology to turn the franchise into a “mobile augmented reality” (MAR) gaming app.

It has proved to be an economic as well as a social phenomenon, sending the market value of its owner Nintendo soaring to US$39.9 billion. But the game was not actually developed by Nintendo; it was created by Google spin-off Niantic, which also built Pokémon GO’s popular MAR predecessor, Ingress.

Similar to Pokémon GO, Ingress is a reality-embedded sci-fi game in which players interact with real-world objects that are overlaid (using smartphone cameras) by a veneer of simulated characteristics.

In a new paper published in the journal Restoration Ecology, we argue that MAR games such as these can be a force for good in ecology and conservation, rather than being a cause for concern, as others have argued.

The key is not to lament or rail against the popularity of gaming or augmented reality, but rather to embrace what makes them a success. They tap into people’s sense of fun and competitiveness, and they get people into the great outdoors – and this is all stuff that can encourage people to embrace nature.

The problem

The growth of our modern civilisation, spurred on by technological innovations, has been underpinned by the exploitation of the natural environment. Today, a large fraction of the Earth, once swathed in wilderness, is now monopolised by humans. Populations of plants and animals have declined, leading to local losses and global extinctions, as a result of habitat destruction, harvesting, invasive species, and pollution.

Yet although the direct causes of wildlife loss are clear enough, what’s less obvious is why many people seemingly don’t care. The environmental writer George Monbiot has ascribed society’s ongoing destruction of the environment to the fact that not enough people value nature and wilderness any more.

This “eco-detachment” has been described as a symptom of our modernised, urbanised world, in which new technology both dominates peoples’ interests and simultaneously increases society’s ability to damage the environment.

But what if augmented reality – from MAR apps on smartphones to HoloLenses – could be harnessed in a positive and proactive way, to reconnect the wider public to nature and so unlock their inherent biophilia?

What if a smartphone game was created that focused not on features of the cityscape, but rather on “gamifying” nature, wildlife, and human interactions with the natural environment?

Such a game would lead its players to actively choose to experience nature. They would connect to it, and protect it (as an in-game reward), and thus understand its value.

Getting more of society to connect with nature has long been an elusive dream of environmentalists. More than a decade ago, a group of leading conservation biologists famously found children were far more expert at recognising Pokémon characters than they were at identifying common wildlife groups. The problem isn’t with spotting “species” per se – it’s that they were mainly exposed to the electronic ones and not the real ones.

This issue of where people invest their attention is crucial. Ingress now has more than 7 million active players, and has been downloaded by 12 million people since its release in 2012. The fact that the game requires you to get out and about means it encourages players to locate, recognise, and identify with an array of cultural icons they might otherwise ignore.

Egress!

So here’s the challenge: to create a new version of Ingress (let’s call it “Egress”), that is educational and positive, as well as popular. It might also use augmented reality to visualise environmental changes, either good (restoration) or bad (damage), in people’s local landscapes. To be a hit, it would need to both capture an audience and to foster a community. And it could even generate data for citizen science projects.

There are lots of possibilities for how an app such as this could work. Perhaps it might involve using smartphones to photograph, locate, and automatically “tag” species within a landscape; or to identify rare plants or insects; or detect signs of animal activity (diggings, droppings, and so on). The crucial point is that although its focus would be on ecology and nature, it needs to also incorporate a fun gaming element – sort of like a high-tech version of those old birdwatching handbooks, but one that offers more kudos for spotting rarer species.

A recent editorial in Nature highlighted some of the potential uses of Pokémon GO, Ingress and others, suggesting that MAR games might even be used to discover and describe new species.

Who doesn’t want a new animal or plant to be named after them? Such citizen science activities would strengthen links between research, conservation, and the community.

What Ingress and Pokémon GO have shown is that it is possible to get millions of tech-savvy people out of their living rooms and basements and actively engaging with the wider world. While it’s impossible to guarantee that any project will go viral, this recent experience with MAR shows that people really can be persuaded, in large numbers, to get outside and explore.

That’s surely the first and most necessary step towards getting people to reconnect with, and care about, nature in the digital age.

Discovery provides possible explanation for increasing deaths of honeybees in recent years, according to scientists

The world’s most widely used insecticide is an inadvertent contraceptive for bees, cutting live sperm in males by almost 40%, according to research. The study also showed the neonicotinoid pesticides cut the lifespan of the drones by a third.

The scientists say the discovery provides one possible explanation for the increasing deaths of honeybees in recent years, as well as for the general decline of wild insect pollinators throughout the northern hemisphere.

Wenlock Edge This time of year, summer throws up the surprising and dangerous, as if to show that beauty and pain are never far apart

Thistles are weeds of ill-repute. In these dog days they make their presence felt, springing like booby traps, their shaving-brush flowers oddly pinkish and purpley, a bit psychedelic for something so spiky. Edgy as the scream of swifts over rooftops, tough as old boots, thistles are the underestimated flowers of summer.

Throughout history they have represented the sharp end of Nature’s retaliation against human meddling. For farmers, the presence of thistles in the field was a sign of neglect and poor husbandry; this weed was synonymous with moral turpitude.

If you live in southern Australia, you may have noticed it’s been a rather wet couple of months. What you might not realise is the role that the tropical Indian Ocean has played in helping to create this weather.

Since late May, the ocean has been in what we call a “negative Indian Ocean Dipole (IOD) phase” – and it seems set to be one of the strongest such events in at least 15 years.

Compared to its Pacific cousins, El Niño and La Niña, the IOD is something of a mystery to many people. So what is it, and what does it mean for our climate, and does it explain why this winter has been such a wet one for many Australians?

What is the Indian Ocean Dipole?

The Indian Ocean Dipole is similar to the more famous El Niño–Southern Oscillation (ENSO) in the Pacific. That system seesaws between El Niño conditions – characterised by a “warm blob” of surface waters in the eastern tropical Pacific – and La Niña, where the warm patch is in the western Pacific.

Similarly, the IOD is defined by the relative distribution of warmer-than-usual water across the tropical Indian Ocean. The system can flip between positive, neutral and negative phases, depending on the presence and position of these “temperature anomalies”.

When the temperatures in the west (off Africa) and the east (off Indonesia and Australia) are roughly normal, we call this a neutral IOD phase.

Explaining the Indian Ocean Dipole

The IOD enters a negative phase (as it did two months ago) when waters in the eastern Indian Ocean become significantly warmer than normal, while waters off Africa are cooler. This happens largely because of prevailing wind patterns.

The Earth’s rotation causes trade winds to blow from east to west, which push warmer surface waters across the Pacific and into the relatively shallow waters north of Australia. This warm water (often the warmest open ocean water in the world) causes a drop in atmospheric pressure over the western Pacific and eastern Indian oceans. In turn, this low pressure induces prevailing winds to blow across the tropical Indian Ocean from west to east.

When these westerly winds strengthen, they push surface waters (which are warmer than deeper water) towards Australia, while at the same time cooler waters are drawn up to the surface off Africa.

The resulting pattern – a blob of warmer-than-normal water in the east and a cooler-than-normal patch in the west – is termed a negative IOD phase. As you can see from the map below for the week ending July 17, we’re in a negative phase now – cooler waters can be seen near the Horn of Africa, and warmer waters near Sumatra.

These conditions increase tropical moisture and cloudiness near Australia. This typically leads to increased rainfall across the southern half of the continent (see below). Conversely, eastern Africa gets less rainfall than normal, which can lead to intense droughts and, at times, quite serious humanitarian impacts.

A negative IOD affects Australia’s temperatures as well as its rainfall. Across the southern mainland, cooler-than-average days are more likely from June to November, although overnight temperatures are generally normal. The snow season typically finishes later and with deeper peak snow, although these impacts are being modulated by climate change.

Meanwhile, Australia’s tropical north tends to get warmer-than-usual days and warmer nights too.

When will it end?

IOD events typically develop during late autumn or early winter, and peak in spring. They then decay rapidly as the monsoon trough arrives in the Southern Hemisphere around the end of spring, bringing a change in wind patterns that rapidly breaks down the IOD pattern. This means that the IOD typically has little influence during the Australian summer.

Are El Niño, La Niña and the IOD linked?

While it’s not always the case, a negative IOD is more likely to form during a La Niña year, while a positive IOD is more likely to form during El Niño.

Indeed, we experienced a combined positive IOD/El Niño event in 2015, which goes a long way to explaining the particularly poor rainfall in many parts of Australia last spring. Typically when the two events occur together, their effects on rainfall are reinforced.

The current state of play

The IOD has been in a negative phase for the past two months, and is likely to stay like that until the end of spring. Recent observations suggest it’s the strongest negative event in at least the past 15 years. What’s more, as of mid-July 2016, about half of international models suggest that La Niña may form later in the year.

So why should we care? The negative phase of the IOD has already influenced recent rainfall – last month was Australia’s second-wettest June in 117 years of national records. This is good news for some of the areas in Victoria, Tasmania and South Australia which were hit hard by the dry conditions associated with the 2015-16 El Niño.

It’s also likely that the negative IOD has contributed to the very warm conditions across northern Australia, which has seen several records set and even had an impact upon tropical crops such as mangoes, which require cool periods to set flower. And if La Niña does become established in the Pacific Ocean, we may have only seen the start of the wet weather.

Australia’s current climate outlook reflects the typical conditions expected during a negative IOD event. However, other factors are at play too, including the overall warming trend of Australia’s climate, the record warm Indian Ocean more generally, the tendency for our weather systems to be located more to the south, and even the occurrence of East Coast Lows which may be more likely this year due to a record warm Tasman Sea.

Campaigner who founded Tiggywinkles, the UK’s first wildlife hospital, and championed new approaches to helping injured and sick animals

Les Stocker, who has died aged 73, was an important friend to Britain’s wildlife, and to hedgehogs in particular. He began the process of giving wildlife care a solid foundation in this country, and founded the first wildlife hospital, Tiggywinkles, in Haddenham, Buckinghamshire.

Before Les began his work in the 1970s, the most common reaction of the veterinary profession to a wildlife casualty was to put an injured animal to sleep, but now there is a range of innovative approaches to the most obscure problems – from repairing birds’ beaks with glue to stitching on a toad’s tongue following a collision with a lawnmower. Les had to re-teach the toad how to use its tongue to catch insects.
