  • Die Qual der Wale

    Von Philip Bethge, DER SPIEGEL 38/2014

    Vor einigen Wochen bereiste ich die Ostküste der USA. Auf der Insel Nantucket, einst Hochburg des Walfangs, erfuhr ich im örtlichen Museum, dass die Indianer die Tiere dort vor 400 Jahren mit kleinen Booten noch direkt vom Strand aus jagen konnten – so viele Wale gab es damals im Atlantik. Dann fuhren wir zum Whale-Watching hinaus aufs Meer, und ich erlebte, wie drei Buckelwale nebeneinander unter unserem Schiff hindurchtauchten – ein unvergesslicher, magischer Moment.

    Die Meeressäuger lassen uns nicht kalt. Diese Wesen sind intelligent, leidensfähig und hochgradig sozial. Das oftmals frustrierende Ringen um den Schutz dieser Tiere darf deshalb nicht aufhören – das Engagement der Artenschützer auf der Tagung der “International Whaling Commission” diese Woche in Slowenien ist sogar wichtiger denn je. Island jagt immer mehr bedrohte Finnwale und exportiert das Fleisch nach Japan. Norwegen vermeldet steigende Zahlen getöteter Zwergwale. Die Grönländer jagen weiter und locken “abenteuerlustige Gourmets” auf ihrer Tourismus-Website mit “Mattak”, Walspeck, ins Land. Und Japan will weiter unter dem Deckmantel der Forschung Walfang betreiben. All das untergräbt das kommerzielle Walfangmoratorium und macht wütend.

    Wer etwas dagegen tun will, kauft keinen Fisch mehr von Firmen wie der isländischen HB Grandi, die eng mit dem Walfang verbunden ist. Auch den Besuch von Delfinarien sollten wir uns sparen. Die Delfinschlächter in der Bucht von Taiji in Japan richten in diesem Jahr auch deshalb wieder ein Massaker an, weil sie einige wenige der Tiere für viel Geld an Zoos verkaufen können. Jedes Delfinarium, auch das in Duisburg oder Nürnberg, befördert eine Kultur, die Meeressäuger zu Clowns macht. Das Fangen und Töten von Walen und Delfinen passt nicht mehr in die Zeit. Sie endlich in Ruhe zu lassen würde uns Menschen ehren.

    Miracle Crop: India’s Quest to End World Hunger

    Over one third of humanity is undernourished. Now a group of scientists are experimenting with specially-bred crops, and hoping to launch a new Green Revolution — but controversy is brewing.

    By Philip Bethge

    It may not make his family wealthy, but Devran Mankar is still grateful for the pearl millet variety called Dhanshakti (meaning “prosperity and strength”) he has recently begun growing in his small field in the state of Maharashtra, in western India. “Since eating this pearl millet, the children are rarely ill,” raves Mankar, a slim man with a gray beard, worn clothing and gold-rimmed glasses.

    Mankar and his family are participating in a large-scale nutrition experiment. He is one of about 30,000 small farmers growing the variety, which has unusually high levels of iron and zinc — Indian researchers bred the plant to contain large amounts of these elements in a process they call “biofortification.” The grain is very nutritional,” says the Indian farmer, as his granddaughter Kavya jumps up and down in his lap. It’s also delicious, he adds. “Even the cattle like the pearl millet.”

  • Windige Windkraft

    Von Philip Bethge, DER SPIEGEL 18/2014

    Dürfen ein paar Wale und Wasservögel die Energiewende behindern? Der Naturschutzbund Deutschland (Nabu) klagt jetzt gegen den Offshore-Windpark Butendiek vor Sylt, weil Bau und Betrieb der Anlage Schweinswale und die extrem scheuen Seetaucher stören könnten. Ein Milliardenprojekt steht auf dem Spiel. Es geht um Haben oder Nichthaben von 288 Megawatt Ökostrom. Und die Naturschützer plagt ein schlechtes Gewissen, weil sie doch eigentlich für den Ausbau der Erneuerbaren sind.

    Dennoch ist die Klage des Nabu vor dem Verwaltungsgericht Köln richtig. Butendiek liegt inmitten von gleich zwei EU-Naturschutzgebieten. Nur weil der damalige grüne Bundesumweltminister Jürgen Trittin das Projekt protegierte, wurden dort schon 2002 80 Windräder genehmigt – gegen den Rat des Bundesamts für Naturschutz. Trittins Entscheidung war falsch. Auch die Windparks Dan Tysk, Amrumbank West und Borkum Riffgrund 2, deren Genehmigungen ähnlich windig sind, müssen auf den Prüfstand. Es gibt genügend alternative Offshore-Standorte, an denen kein Schweinswal kalbt und kein Prachttaucher fischt.

    Bereits heute sind in der Nordsee 28 Windparks mit etwa neun Gigawatt Leistung genehmigt. Über 50 weitere Parks sind in Planung. Gleichzeitig deckelt die Novelle des Erneuerbare-Energien-Gesetzes den Windstrom auf 6,5 Gigawatt bis 2020 und auf 15 Gigawatt bis 2030 – Zeit und Spielraum genug, um ökologisch verträgliche Offshore-Standorte auszuwählen. Das Bundesamt für Naturschutz muss die bereits begonnenen Rammarbeiten für Butendiek sofort stoppen. Sonst ist der Umweltschaden angerichtet, bevor über die Nabu-Klage vor Gericht entschieden wird. Und am Ende muss womöglich der Steuerzahler für den Rückbau eines halbfertigen Windparks geradestehen. Deutschland braucht Butendiek nicht – aber seltene Tiere brauchen ihre Rückzugsräume.

  • Hydropower Struggle: Dams Threaten Europe’s Last Wild Rivers

    Europe’s last remaining wild rivers flow through the Balkans, providing stunning scenery and habitat to myriad plants and animals. But hundreds of dam projects threaten to do irreparable harm to the region’s unique biospheres — to provide much needed electricity to the people who live there.

    By Philip Bethge

    How did Europe’s rivers look before they were tamed — back when they were allowed to flow freely through the beds they spent centuries carving out?

    Most of the Continent’s waterways, like the Elbe, the Rhine and the Danube, have long since been hemmed in. But examples of Europe’s largely vanished wilderness remain. Such as the Vjosë, which flows unfettered through its valley in southwestern Albania, splitting off into tributaries that once again flow together in a constant game of give-and-take with solid ground.

    “With every flood, the Vjosë shifts its course,” says Ulrich Eichelmann, a conservationist with the organization RiverWatch, as he looks across to the narrow ribbon of alluvial forest that clings to the side of the valley. “The river fills the entire valley,” says the 52-year-old. “Such a thing in Europe can only be found here, in the Balkans.” Then he pauses. On the opposite shore, a cormorant takes flight.

    The Vjosë: 270 kilometers (168 miles) of river landscape, from the Pindus Mountains of Greece all the way down to the Adriatic Sea. Not a single dam disturbs the water’s course. No concrete bed directs its flow. And every pebble tells a story, says Eichelmann — of pristine mountain enclaves, of waterfalls, gorges and lakes.

    The ‘Blue Heart of Europe’

    The Vjosë is not alone. Several crystal clear, untamed rivers rush through many countries in the region. “The blue heart of Europe beats in the Balkans,” says Eichelmann, who, together with environmental organization EuroNatur, works to preserve these natural water systems….

  • Reeling In the Trawlers: EU Takes On Overfishing

    Fish stocks have made surprising comebacks in the North and Baltic seas. But much remains to be done. Beginning in January, new EU laws will impose more sustainable practices with stricter quotas and by-catch rules.

    By Philip Bethge

    When the men open the net on the ship’s deck, fat codfish slap into plastic fish baskets. Slippery plaice and flounder, rough as sandpaper, gasp for air. Turbot the size of two strong fisherman’s hands slither between silvery herring and flat dabs.

    A particularly large cod with its mouth wide open lies on top of the pile. “It has to weigh more than six kilos (13 lbs.),” estimates Martina Bleil as she looks down at the fish. “It’s in great shape.” The female is about 8 years old, says Bleil, a fish biologist. “It would have been spawning again soon.”

    Bleil works for the Thünen Institute for Baltic Sea Fisheries (Thünen OF) in the northern German port city of Rostock, an agency that is part of Germany’s Federal Ministry of Agriculture. The scientist and her colleagues have made a big haul on this clear November day in the Bay of Mecklenburg. “We are headed in a very good direction with fish stocks in the Baltic Sea,” says Bleil. “Anyone who eats plaice or herring doesn’t have to feel guilty about it anymore.”

    Something amazing is happening in the seas off Germany’s coasts, where most species were long considered overfished. But now some stocks are recovering at an astonishing rate. Experts are seeing a significant upward trend in the North Sea, and even more so in the Baltic Sea.

    “We assume that the Baltic Sea will be the first European body of water that can be sustainably fished once again,” says Christopher Zimmermann, director of the Thünen OF. “That would be a huge success.”

    Ending ‘Horse-Trading” with Reform

    This year, the European Union has also launched a reform of its Common Fisheries Policy (CFP) that Zimmermann believes “will accelerate the positive trend even further.” In fact, the new rules could ring in a historic turning point.

    “In the past, the group of ministers was setting fishing quotas in cloak-and-dagger meetings,” says Ulrike Rodust, a member of Germany’s center-left Social Democratic Party (SPD) and a lawmaker in the European Parliament from the northern state of Schleswig-Holstein. Rodust played a key role in pushing through the reforms in Brussels. But now, she says, the system of “horse-trading” among members that inadequately protects fish stocks has come to an end.

    Rodust expects that stricter maximum catch restrictions will lead to a trend reversal throughout Europe. The regulation, which comes into effect in January, stipulates that:

    In the future, fishing quotas will be established exclusively on the basis of scientific criteria. The goal is to ensure that all stocks are fished only to the “maximum sustainable yield” by 2020.

    Unwanted by-catch is to be brought to shore and included in the total subject to quotas. The more by-catch fisherman have in their nets, the less marketable fish they can catch. The rule creates an incentive to use more selective fishing methods.

    Subsidies for building new trawlers are being eliminated. Instead, more money will be available to monitor fishermen and conduct scientific studies of fish stocks.

    The new rules will also apply to EU fishermen operating outside Europe. This means that European trawlers will no longer have the option of simply shifting to fishing grounds off the coasts of Africa.

    The details of the fishing regulations are being negotiated regionally. Soon the same rules could apply in both the Irish Sea and off the Spanish coast.

    Stocks in ‘Excellent Shape’

    –> Read original story at SPIEGEL ONLINE International

    In the Baltic Sea, fishing reform has almost reached the goals that lawmakers hope to achieve in other European maritime regions in the future. This success story was made possible by the agreement among countries bordering the Baltic Sea to exclusively employ sustainable fishing practices, says Zimmermann.

    This hasn’t always been the case. Until 2007, for example, Polish fishermen were pulling about twice as much cod out of the water as EU rules permitted. It was only the new government under Prime Minister Donald Tusk that began “reining in the trawlers,” says Zimmermann. “But now the Poles are also abiding by the rules.”

    Baltic Sea fishing policy has been an immense success. Cod in the eastern Baltic, for example, which was still heavily overfished in 2005, is now doing “very well,” Zimmermann reports, while plaice stocks are in “excellent shape.” And herring in the eastern Baltic are now producing young at a healthy rate once again.

    Some fish species are also doing better in the North Sea. Researchers at the Thünen Institute for Sea Fisheries in Hamburg recently studied 43 fish stocks and concluded that 27 of them are in “good ecological condition.” According to the Federal Ministry of Agriculture, “more than half of the fish stocks in the North Sea and northeast Atlantic” are already “being managed sustainably” today.

    Herring and plaice, in particular, are developing well in the North Sea, says Zimmermann. Even North Sea cod, long a subject of concern for biologists, is finally showing initial signs of recovery, he adds.

    The Benefits of Stricter Quotas

    Zimmermann is one of the architects of this fishing miracle. He represents Germany on the International Council for the Exploration of the Sea (ICES), which develops recommendations for EU catch quotas. The data used to analyze fish stocks in the Baltic Sea are obtained with research ships like the Clupea.

    Fish biologist Martina Bleil makes regular trips out to sea, where she and her assistants use a standardized TV3/520 research net. In the water, the net opens to a width of 20 meters (66 feet) and a height of two meters. With a mesh size of only 22 millimeters, hardly any swimming marine animal can escape the research net.

    On this November day, Clupea Captain Rolf Singer heads for two catch sites. Once the catch is on board, Bleil grabs one cod after another and hoists them onto a nearby table, where she measures them. “84 centimeters long,” she calls out to her assistants. With a practiced hand, she uses a pair of scissors to slice open the animals’ bellies. Bleil’s plastic gloves are stained red. Fish blood drips onto the green working deck. “Female,” she calls out. “Stomach: 65 grams; liver: 170 grams.”

    Data collection is the basis of the ICES recommendations. Experts have reduced the maximum allowable catches for many fish stocks in recent years. While stocks have often been radically overfished, the strict sustainability principle will apply as of January.

    The objective is to regulate fishing in such a way that fish stocks can stabilize or even grow in the long term, as well as to enable fishermen to continually harvest “the maximum yield with minimum effort,” as Zimmermann puts it.

    If stocks are doing well, there are more fish to catch, which enables fishermen to benefit from the reform. The overfished cod stock in the North Sea, for example, has provided an annual yield of no more than 40,000 metric tons for the last decade. If the stock were in good shape, Zimmermann explains, fishermen could easily catch more than three times as many fish.

    This explains why there are good reasons to reform EU fishing policy, especially as catches in many places have well exceeded scientific recommendations in the past. In addition, about a quarter of the fish caught by EU fleets are by-catch and directly returned to the water. But extremely few of these fish survive.

    “Overfishing must come to an end,” says Rodust, and she is confident that his goal can be achieved. All EU fish stocks are to be fished using the new, more sustainable methods by 2015, if possible, and by no later than 2020. The EU could serve as a role model worldwide, says Rodust, adding: “We have received a great deal of praise internationally for our reforms.”

    Fears of Fishing Lobby Manipulation

    But not all fishing experts see this in quite as positive a light. “The reform is supposed to be implemented by precisely the same people who were responsible for massive overfishing in the last few decades,” says Rainer Froese of the GEOMAR Helmholtz Center for Ocean Research in the northern German port city of Kiel.

    Since scientific recommendations are to become binding in the future, Froese fears that the fishing lobby could try to put pressure on scientists. This, in turn, could lead to the ICES quota recommendations being too high.

    According to Froese, sustainable management should only be considered once stocks have recovered. He points out that the situation is not improving for all fish stocks.

    “Eel and pollock are still being heavily overfished in the Baltic Sea,” says the biologist. While cod is in better shape in the eastern Baltic, the species remains under strong pressure west of the Danish island of Bornholm. In the North Sea, says Froese, stocks of cod and pollock are still a long way from recovering, while eel and spiny dogfish are even “acutely threatened.”

    Froese is also opposed to the subsidies. “Although they have been restructured, they haven’t been reduced,” he says. Subsidies for ship fuel, for example, continue to allow for the use of massive, heavy ground tackle that tears up the ocean floor, destroying important habitats for young fish.

    “We are currently still in hell and are marching toward the gates of paradise,” Froese concludes. “The question is whether we will halt at the threshold or walk through.”

    Zimmermann, on the other hand, prefers to convey a sense of optimism. “As a rule, the only thing grumbling achieves,” the Thünen OF director explains, “is that people say: ‘Oh God, the best thing is stop eating fish altogether,’ and to eat turkey from factory farms instead.” Many types of saltwater fish can be “enjoyed with a good conscience” once again, he adds.

    The biologist even believes that some stocks in the Baltic Sea are being “under-utilized.” Cod stocks in the eastern Baltic, for example, have grown to such an extent that the animals are “starting to eat each other and compete for food,” he says.

    According to Zimmermann, one in five cod in the Bornholm Basin is so thin that it can no longer be cut into fillets. Fishermen refer to these fish as “triangular rasps” because they are so bony. The animals can no longer be sold, says Zimmermann, “so they end up in fishmeal production.”

  • Vultures lured back to Germany

    Vultures are slowly returning to Germany, driven out long ago by an unwelcoming populace. At the behest of conservationists, loosened “carcass regulations” in Europe have made the search for food less daunting — but some still wonder if the birds will be able to survive.

    By Philip Bethge

    Griffon vulture number 259 is no longer able to fly. A bullet from a small-caliber rifle wielded by an unknown shooter shattered the ulna and radius of the bird’s wing in June. Veterinarians tried to rehabilitate the vulture, using physical therapy to strengthen its wing muscles and even applying leeches to improve circulation, but nothing worked.

    “It’s over for him,” says Wolfgang Rades, director of Herborn, a bird park in the central German state of Hesse. Rades casts a concerned glance toward the vulture, where it crouches on a pile of stones in a corner of its enclosure, looking a sad sight on this cold, damp morning. Yet for Rades, the bird is also a sign of hope. “He’s an ambassador for others of his kind living in the wild,” the biologist says. “Many more vultures will follow him, if we humans allow them to.”

    Griffon vulture 259 is among the vanguard of a new avian presence in Germany. Vultures are returning to the country, slipping stealthily into German airspace and often flying at heights of over 1,000 meters (3,300 feet). Ornithologists, glider pilots and hang gliders have all spotted these carrion-feeders above cities such as Hanover and Freiburg and regions such as the Black Forest and the Swabian Jura (see map).

    “At least 50 to 60 vultures have been sighted in Germany this year,” says Dieter Haas from the Vulture Conservation Initiative (GESI) based in Albstadt, southwestern Germany. “And many more are sure to follow.”

    Ornithologist counted 26 griffon vultures just in mid-June in the area outside the town of Tessin in northeastern Germany. And from April to August, a bearded vulture named Bernd delighted bird lovers by flying all the way from the Alps to the Baltic Sea. Even cinereous vultures, a rare species with a wingspan of nearly three meters, have been spotted in German skies.

    Others may revile these species as supposed harbingers of death, but bird lovers are thrilled. “Vultures provide the best disposal service nature has to offer. They perform an important ecological function,” says Haas, who has observed vultures feeding numerous times. They plunge from the sky “like stones” when they spot a carcass on the ground, he says of such spectacles, and set to work on their find. “They gobble everything up and then they’re gone again.” Haas considers these birds “a gift from the skies.”

    EU Takes Away Food Source

    All four European vulture species — the bearded, cinereous, griffon and Egyptian vultures — were once native to Germany, but humans were no fans of the birds.

    A century ago, when vultures still lived here, people in the Alps believed bearded vultures stole lambs, goats and even small children. They called the birds “bone crushers,” for the way they dropped their prey from great heights onto rocks, smashing the bones to get at the marrow, their favorite food. Local lords offered a bounty for hunting the birds. In 1913, a hail of birdshot tore apart what is presumed to have been the Alps’ last bearded vulture, in the Aosta Valley, Italy.

    Many griffon vultures, meanwhile, perished from poison bait that was meant for wolves and foxes. Pesticides, too, are harmful to vultures, since they accumulate in the bodies of the animals on which vultures feed.

    More than anything, though, vultures disappeared because their once plentiful source of food ran dry — and remains so to this day. A 2002 EU hygiene regulation, also called the “carcass regulation” by conservationists, stipulates that germs from animal carcasses must be prevented from making contact with drinking water, to keep animal-borne diseases in check. The law was primarily introduced to stem the spread of bovine spongiform encephalopathy (BSE), or mad cow disease, but it also applies when a sheep gets its skull split open by lightning or a deer meets its end at the bumper of a car. No dead livestock may be left lying in the open, and hunters must either take the carcasses with them or quickly bury them.

    The new regulation kept European woods tidy — but there was nothing left for vultures to eat.

    Farmers in Spain, for example, had to close down their “muladares,” traditional spots where for centuries they had tossed carcasses for vultures to feed on, a hygienic method of disposing of dead animals.

    ‘Vulture Alert’ in Germany

    With their food source now gone, hungry vultures began attacking even living livestock. And in 2006, Germany experienced its first influx of vultures, as the emaciated birds flocked in to look for food. Coming as it did in the middle of the summer news slump, the arrival of birds such as a griffon vulture nicknamed “Gonzo” made headlines. German mass-circulation daily Bild reported a “vulture alert in the north.”

    Three years later, lawmakers eased the “carcass regulation” in response to pressure from conservationists. Spain’s muladares are back and the country’s vulture population has grown again, to around 25,000 pairs. Biologists have succeeded in reintroducing vultures into the French Alps as well. “It’s fantastic, they’ve seen griffon vultures and steinbock on the same crags out there,” Haas says enthusiastically.

    It’s no surprise, then, that the carrion-feeders have struck out for Germany as well. Young vultures are true distance travelers, undertaking wide-ranging exploratory flights before they start to breed between four and six years of age.

    Such was the case with one early adopter, the bearded vulture Bernd — so nicknamed, although the bird later turned out to be female. In 2012, Bernd was fitted with a radio transmitter and released into the wild in Switzerland. This year, on May 17, Bernd began a journey northward.

    Bernd flew first over Bavaria and the Czech Republic, then as far as Poland’s Baltic Sea coast, before turning west. She continued on past the cities of Stade and Bremen, then headed south once again. But then, near the city of Bayreuth, Bernd’s radio signal suddenly cut out. Bird lovers feared the vulture had suffered a violent death, but those fears were soon allayed. “The female bearded vulture appears to have managed to get rid of her radio tag,” conservationists announced online on June 13. Then on June 19 came the news: “Bernd is alive!” The bird was found, weakened, in the German state of Saxony. She was rehabilitated and returned to the wild in the Alps.

    Can Vultures Be Fed?

    When caught, Bernd was near death, having found too little food in Germany. It’s a common scenario. In June, a griffon vulture was spotted at a landfill outside the city of Vechta in northern Germany. “It sat around there for days and grew visibly weaker,” recalls Ludger Frye from the local chapter of Germany’s Nature and Biodiversity Conservation Union (NABU).

    Frye decided to feed the vulture. “But it was more difficult than I expected,” he says. Frye spoke with the landfill operator and with conservation and hunting authorities. He could give the bird game carrion, he was finally told. Frye found a couple pieces of venison “in a carcass bin” and threw them to the vulture. “Then the bird started doing better,” he says. Soon, it continued on its way.

    Frye is pleased with this success, but not precisely happy with the general situation. “If these animals don’t find anything to eat here, we’ll never get them back,” he says.

    It’s true that Germany is not yet a vulture paradise. “We’re overly concerned with hygiene,” says Rades at the bird park in Hesse. He points out, for example, that wildlife hit by cars in Germany still gets cleared away in next to no time. “Why don’t hunters just move carrion 100 meters or so into an open field and leave it for the vultures?” the biologist asks. And, he adds, why not re-establish specific locations for feeding these birds?

    Haas from the Vulture Conservation Initiative has set up one such spot already. In the Danube River valley outside the town of Sigmaringen, he regularly brings found carrion to a field belonging to a shepherd friend of his. Haas reports that he’s seen some vultures circling above the field, but so far none has landed. “They don’t quite dare,” he says. Next, he wants to try bringing in vultures from zoos — ones that have had accidents and are no longer able to fly, what Haas calls “crash vultures” — to provide a “trust-building measure” for the wild birds.

    Habitat Restoration

    Will offering food to these birds of prey really work? Supplying the birds’ flight routes with enough meat would call for a fair number of carcasses. The demand would amount to “one cow per year for each vulture,” calculates Haas, who dreams of setting up observation platforms near such feeding sites as a draw for eco-tourists. He imagines an afternoon outing to watch vultures feed would present an almost irresistible attraction. “People could experience something really worthwhile,” Haas says.

    That idea, though, goes too far even for some bird experts. Lars Lachmann of NABU, the conservationist group, finds it a bit premature to be feeding vultures. “With the current low population numbers, at the moment that would just lead to carcasses lying around everywhere, which people would then blame on conservationists,” he says.

    Instead, Lachmann wants to restore the birds’ habitat. Vultures need rocky outcroppings and open pastures where a sheep might now and then fall dead without immediately being “disposed of according to regulation,” Lachmann says. “Then the vultures will come of their own volition.” He considers the foothills of the Alps, the Swabian Jura and the Harz Mountains in central Germany all to be “potential griffon vulture country.”

    What remains to be seen is whether or not the general public will give these strictly protected carrion-feeders a warm welcome. Cases such as that of griffon vulture 259, the bird felled by a rifle bullet, make it seem as though the writing may already be on the wall. Whoever shot the bird was most likely not a hunter, biologist Rades says, but a “gun nut with a small-caliber rifle.” It seems ignorance and prejudice may once again seal the fate of vultures in Germany.

    A different approach is possible, though. Haas tells the story of 23 griffon vultures that turned up one day in the Lorraine region of France and prepared to spend the night in the woods there. “Right away, someone jumped in and provided them with two dead sheep,” he says. The next morning, the same French man “took pictures of the vultures and put a great story up online.”

  • Flipper Fail: Dolphins May be Dumber Than We Think

    For decades, it’s been common knowledge that dolphins are among the world’s smartest species. Now some researchers — and a new book — argue the supposed underwater geniuses aren’t so special after all.

    By Philip Bethge

    Their social lives are complex, and they can congregate in large groups. Their heart rates increase when they notice a family member suffering. They sound the alarm when they discover food or a potential threat. And experiments have shown they even anticipate future events.

    Biologist Justin Gregg is talking about chickens.

    Chickens, says Gregg, “are not as dim-witted as popular opinion would have us believe.” He adds, “Some of these complex behaviors have also been observed in dolphins.”

    Really? Are chickens as smart as dolphins? Or, to put it differently: “Are dolphins really smart?” This is the question Gregg, a zoologist with the US-based Dolphin Communication Project, asks in his new book of the same name. And he isn’t the only one finding fault with Flipper’s brainpower.

    For more than 50 years, the dolphin has been viewed as an especially intelligent creature, grouped together with human beings and great apes. But now a dispute on the subject has erupted among scientists, and the smart aleck of the seas may end up being just an average mammal. “We put them on a pedestal for no reason and projected a lot of our desires and wishes on them,” says neuroethologist Paul Manger of the University of the Witwatersrand in South Africa. According to the professor, the claims that dolphins have a particularly complex brain, use a sophisticated language, are self-aware and can use tools are nonsense.

    In some cases, says Manger, dolphins — which are small whales — are even outdone by goldfish. When goldfish are placed in a bowl, he explains, they at least try to escape by boldly jumping out, whereas dolphins that have been captured in nets won’t even think of jumping to freedom. “The idea of the exceptionally intelligent dolphin is a myth,” Manger concludes.

    Origins of the Dolphin Myth

    In the 1950s, physician and neuroscientist John Lilly played the crucial role in the elevation of dolphins from the status of stupid, fish-like creatures with excellent swimming skills to that of underwater know-it-all. In eerie-sounding experiments, Lilly attached electrodes to the brains of living dolphins to stimulate neurons. One day, a dolphin hooked up to his equipment began making loud noises as it approached its horrible death. When Lilly slowed down and played back the audio recordings, he concluded the dolphin was trying to communicate with its tormenters.

    After further experiments, Lilly became convinced dolphins had a human-like faculty of speech and attempted to establish contact with the marine mammals. His desire to communicate was so great he administered LSD to himself and the dolphins in the hopes of stimulating conversation.

    He soon moved to the American West Coast, where he became a spiritual leader of the hippy generation and wrote books in which he combined New Age ideology with half-baked dolphin research. The animals, Lilly gushed, were “more intelligent than any man or woman.” He even attributed them philosophy, ethics and an “ancient vocal history.”

    Lilly’s muddled legacy shapes our image of dolphins to this day. Artists paint watercolors of the animals swimming through outer space. In popular lore, dolphins serve as ambassadors of peace and unconditional love, and, the more out-there believe they possess miraculous healing powers and can teleport space-age settlers to Mars. Behavioral scientists, along with most reasonable people, agree this is all nonsense. Still, the size of dolphins’ intellect remains a matter of dispute.

    What’s a Big Brain Worth?

    One measure scientists use to determine a creature’s intelligence is brain size — given the theory that the more a brain weighs relative to the body, the smarter the animal. A human brain, which weighs about 1,300 grams (46 oz.), makes up about 2 percent of body weight. A chimpanzee’s brain comprises 0.9 percent of its weight, while the corresponding number in elephants, with their brains weighing in at more than 4.5 kilograms (9.9 lbs.), is 0.2 percent. Dolphins do well by comparison. The brain of a bottle-nosed dolphin, for example, weighs more than 1,800 grams, or 0.9 percent of its average body weight.

    It seems logical that dolphins deserve to be included in the animal Mensa Society. But does a large brain mean the same in marine mammals as it does in terrestrial animals? In 2006, Paul Manger noted that whales developed a large brain in order to keep the organ from becoming hypothermic, and thereby useless, in cold water.

    Manger described an unusually high density of so-called glial cells in the animals’ brain matter. He explained that these cells act like tiny ovens to keep the brain warm. Besides, he added, dolphins have a relatively simple brain structure, and noted: The essential features of complex neural processing of information, as observed in other mammals, are missing or poorly developed.”

    No Better Than Mealworms?

    Manger has now upped the ante with a new paper in which he claims behavioral studies involving dolphins are flawed and therefore not very informative. For instance, while zoologists have observed that dolphins can distinguish between the concepts “many” and “few,” Manger notes: “This has also been demonstrated in yellow mealworms.”

    On the other hand, some bottle-nosed dolphins on Australia’s west coast have learned to hold sponges over their snouts while they root around on the ocean floor. Is this a case of tool-use, indicating a high level of intelligence? Manger is skeptical. “Exactly what the dolphins do with the sponges remains unknown,” he says, noting that the evidence they use them as tools is “flimsy.”

    Another example is dolphins’ alleged talent for language. In one experiment, researchers were able to teach bottle-nosed dolphins 40 symbols. The animals were even capable of correctly interpreting combinations of the symbols, Manger admits, but African grey parrots and California sea lions can also learn this type of symbol-based language.

    The scientific community is similarly divided over what zoologist Gregg calls “Dolphinese.” It is known that every dolphin can identify itself with its own “signature whistle.” The marine mammals use many other acoustic signals, he adds. But is this truly special? The tail-wagging dance of bees is also very complex, says Gregg. “It’s probably not the case that dolphins have their own language, which is as complex as human language,” says the expert in animal communication.

    Dolphin Defenders

    So is the dolphin actually the dummy of the seas? Most dolphin researchers are offended by such remarks. “To put it bluntly, most of that is bullshit,” says Karsten Brensing, a marine biologist with the organization Whale and Dolphin Conservation (WDC). Manger and Gregg are losing sight of the “total package” when they compare the marine mammals’ individual abilities with those of mealworms or bees, he says. “You can use similar arguments to prove that people aren’t intelligent.”

    Lori Marino, a neuroscientist at Emory University in Atlanta, also has strong objections to Manger and Gregg’s conclusions. “We shouldn’t dismiss decades of peer-reviewed scientific work,” she says, noting there are overwhelming indications that dolphins possess a high degree of intelligence. For instance, scientists have observed how the animals work together to encircle schools of fish. To cultivate relationships, they spoil each other with their own form of “petting” behavior. And in a struggle for power, males will join together to form networks.

    Marino even believes that dolphins can recognize themselves. In a famous experiment, she and psychologist Diana Reiss drew markings on the bodies of two dolphins. Then they held up a mirror to the animals. They were fascinated to observe the animals turning around like divas in front of the mirror, presumably to examine their new body decorations.

    For Marino, this is evidence of self-recognition, similar to what has been observed among great apes. She and other scientists even want to see the animals given the legal status of persons and granted “some fundamental rights,” such as the right to bodily integrity.

    None of this convinces Manger, who has a low opinion of Marino’s mirror experiment. “The visual acuity of dolphins is actually not good enough to be able to readily perceive such marks,” he says, and is critical of what he calls “serious deficiencies” in the design of the experiment.

    Stop Calling Them ‘Special’

    Manger is accustomed to his theories being rebuffed. When he questioned the special features of the whale brain in 2006, dolphin fans called upon Manger’s university to suspend him. But he merely wants to prevent the marine mammals from being anthropomorphized. Interpretations of behavior based on “personal bias” are not helpful, says Manger. “Conservation strategies should not be based on unrealistic expectations.”

    Gregg’s primary objective is also to debunk the myth. “We have to stop describing them as ‘special’,” says Gregg.

    It is becoming increasingly apparent that the marine mammals’ intellectual abilities are by no means unique in the animal kingdom. “Many other species-from sharks to earwigs to rats-lead equally wondrous and worthy lives,” he writes.
