Zoos Struggle to Breed<br />

Rare Species in Captivity<br />

By LESLIE KAUFMAN<br />

FRONT ROYAL, Virginia — With extinctions<br />

rising and habitats being destroyed,<br />

zoos are trying to breed about<br />

160 endangered species.<br />

But 83 percent of those species in North<br />

American zoos are not meeting the targets<br />

set for maintaining their genetic<br />

diversity, the Association of Zoos and<br />

Aquariums reports.<br />

After two decades, the captive population<br />

of 281 cheetahs in North America<br />

gives birth to only 15 cubs, on average, a<br />

year, half of what is needed to maintain a<br />

healthy replacement level. And they are<br />

not nearly as difficult to breed as pandas,<br />

which last produced a cub in captivity in<br />

America in 2010.<br />

Zoos must learn to mate animals as socalled<br />

insurance populations, before their<br />

situation in the wild becomes untenable,<br />

said Jack Grisham, who coordinates the<br />

association’s cheetah breeding plan. The<br />

disappointing success rate has led many<br />

to say they would prefer to see the money<br />

Captive cheetahs don’t<br />

reproduce quickly enough<br />

to ensure their future.<br />

go to preserving wild habitats and species.<br />

“I’d be happier about captive breeding<br />

if I thought it helped wild cheetahs,” said<br />

Luke Hunter, president of Panthera, a<br />

nonprofit group with offices in New York<br />

and London that works on global conservation<br />

efforts for big cats in the wild, including<br />

cheetahs. “Free of threats, they<br />

breed like rabbits in the wild. They don’t<br />

need supercostly assisted reproduction<br />

— they need a place to roam.”<br />

Each year the Smithsonian’s National<br />

Zoo in Washington spends about $350,000<br />

on breeding cheetahs at its 1,300-hectare<br />

campus here in Front Royal, which houses<br />

18 other species. Similar programs exist<br />

at four other centers run by zoos.<br />

At the turn of the 20th century, roughly<br />

100,000 cheetahs roamed from Africa to<br />

the Mediterranean to India, according<br />

to the Smithsonian. Today, experts estimate<br />

7,000 to 10,000 remain in the wild as<br />

a result of habitat loss, poaching, and conflicts<br />

with farmers and ranchers.<br />

Mr. Grisham said the pressures on<br />

animals in the wild are so great that zoo<br />

The summer vacation season in the<br />

United States is under way and many are<br />

planning to go … nowhere.<br />

animals may someday have to serve as a<br />

genetic insurance bank.<br />

In a closed population, as in zoos, the<br />

priority is high levels of genetic diversity<br />

to maintain a species’ adaptability and<br />

prevent inbreeding. The result is a kind<br />

of reverse natural selection, with the animals<br />

with the lowest rate of success vaulting<br />

to the top of the priority list because of<br />

the rareness of their genes.<br />

Many zoos do not have enough genetic<br />

variation to ensure long-term survival<br />

in captivity. “Noah got it all wrong,” said<br />

Sarah Long, director of the Population<br />

Management Center in Chicago. “One or<br />

two or even a dozen of each species is not<br />

enough.”<br />

The association runs nearly 600 cooperative<br />

breeding programs, but so far<br />

has formal breeding plans for only 357<br />

species. About 55 percent of those species<br />

with plans are considered imperiled<br />

in the wild by the International Union for<br />

Conservation of Nature, among them the<br />

western lowland gorilla and the scimitarhorned<br />

oryx.<br />

Still, 40 percent of those 357 managed<br />

populations are dwindling. The number<br />

of Andean bears is shrinking because<br />

zoos scaled back breeding years ago and<br />

the population has become too old to reproduce.<br />

The Nile lechwe, an antelope,<br />

is believed to be suffering in captivity<br />

because zoos are allocating less space to<br />

rare hoofed species.<br />

Researchers lack adequate knowledge<br />

on artificially inseminating many exotic<br />

animals, so for now, most zoo animals<br />

mate the old-fashioned way, which presents<br />

its own logistical puzzles.<br />

An institution may be reluctant to give<br />

up a popular chimp or penguin. Animals<br />

available from overseas can be blocked<br />

by agricultural treaties, diplomatic problems<br />

or quarantines.<br />

And animals, like humans, have their<br />

own ideas about their mates.<br />

African penguins are generally monogamous.<br />

At the New England Aquarium in<br />

Boston, they are paired by keepers with<br />

an appropriate genetic match.<br />

But some 25 percent of the time the penguins<br />

refuse the designated suitor.<br />

Researchers are still trying to master<br />

the dynamics of cheetah mating, said<br />

Adrienne Crosier, director of the National<br />

Zoo’s cheetah breeding program.<br />

For decades, zoos housed and treated<br />

all big cats similarly. But their mating<br />

patterns can be radically different. For<br />

example, clouded leopards, a critically<br />

LUKE SHARRETT FOR THE NEW YORK TIMES<br />

Zoos are trying to mate animals before their situation in the wild becomes<br />

and dine at the best restaurants. But Neil<br />

Genzlinger writes in The Times that producers<br />

of these shows fail to understand<br />

the American sensibility.<br />

“There’s nothing mainstream Americans<br />

like better than listening to, and<br />

hanging out with, people exactly like<br />

themselves,” Mr. Genzlinger wrote. “That<br />

means we don’t want shows about exotic<br />

adventures; what we want is a Staycation<br />

Channel.”<br />

These days many Americans are just<br />

happy to have a job and fear time away<br />

from the office may become permanent if<br />

the boss notices they aren’t really missed.<br />

Even President Obama, whose job security<br />

is an open question, is forgoing his annual<br />

beach getaway to the upscale island<br />

of Martha’s Vineyard.<br />

Marketers have noticed, Tanzina Vega<br />

reported in The Times. They are rolling<br />

out commercials that urge “workers to<br />

commit small acts of so-called rebellion —<br />

like taking a vacation, or going on a lunch<br />

break.”<br />

In a television ad for Las Vegas, one<br />

worker climbs on her desk in a busy office<br />

and yells: “I have 47 vacation days. That’s<br />

insane. Let’s take back our summer!” She<br />

holds up a sign that says “Vacation Now.”<br />

“Who’s with me?’ ” she asks. Some applaud.<br />

The rest look away.<br />

Part of the problem may be that many<br />

of us just don’t know how to “take back the<br />

summer.” Times reporter Matt Richtel had<br />

that problem in Hawaii. A seven-day break<br />

in March to enjoy the islands was spent<br />

checking his phone, lamenting the rain<br />

and dealing with his jet-lagged toddlers.<br />

He wrote: “I had hoped to return home at<br />

peace. Instead I was exhausted, defeated<br />

and irritable.”<br />

So for his next trip, Mr. Richtel consulted<br />

with experts, who were kind enough not to<br />

point out that if he needed advice on how to<br />

relax, that might be part of the problem.<br />

Few consumers have ever heard of<br />

Acxiom Corporation, which is based in<br />

Little Rock, Arkansas, but has offices<br />

in Australia, New Zealand, France,<br />

Germany, Britain, Poland, Brazil and<br />

China. Analysts say it has amassed the<br />

world’s largest commercial database<br />

on consumers — and that it wants to<br />

know much, much more. It has more<br />

than 23,000 servers processing more<br />

than 50 trillion data “transactions” a<br />

year. Company executives have said its<br />

database contains information about<br />

500 million active consumers worldwide,<br />

with about 1,500 data points per<br />

person.<br />

Such large-scale data mining and analytics<br />

— based on information available<br />

in public records, consumer surveys<br />

and the like — are perfectly legal in the<br />

United States. Acxiom’s customers have<br />

included big banks like Wells Fargo<br />

and HSBC, investment services like<br />

E*Trade, automakers like Toyota and<br />

Ford, department stores like Macy’s —<br />

just about any major company looking<br />

for insight into its customers.<br />

For Acxiom, the setup is lucrative. It<br />

posted a profit of $77.26 million in its<br />

latest fiscal year, on sales of $1.13 billion.<br />

But such profits carry a cost for consumers.<br />

Authorities in the United States<br />

say present laws may not be equipped to<br />

handle the rapid expansion of an industry<br />

that often collects and sells sensitive<br />

financial and health information yet is<br />

untenable. A baby cheetah at the National Zoo in Washington. MINH UONG/THE NEW YORK TIMES<br />

Barbara, learned the last lesson the hard<br />

way. During a recent family trip to Norway<br />

he thought he could fit in a little work, he<br />

told Mr. Richtel. He’d take out his laptop,<br />

fiddle, not get much done. But he never<br />

fully relaxed either.<br />

Professor Schooler should know better.<br />

Really. His research has shown that<br />

people are more creative when they let<br />

themselves daydream or do only mildly<br />

engaging mental tasks.<br />

“Part of the problem is that we don’t<br />

really believe in the value of incubation<br />

and the value of mind wandering,” he told<br />

Mr. Richtel, adding with a laugh, “I’m still<br />

ruining vacations by taking work with me,<br />
