Another important aspect of modern research is the ethical impact of the
research. A researcher
must consider carefully whether the results of the
research will negatively impact any of the groups
involved. In an increasingly
globalised job economy, generalisations made about nationalities can be
harmful to prospective employees. This information could also impact the way
tests and university
admissions standards are designed, which would potentially favor one group or create a disadvantage for
another. When
conducting any research about culture and nationality, researchers should
consider all
possible effects, positive or negative, that their conclusions
may have when published for the world to see.

TEST 8 – Monkeys and Forests
AS AN EAST WIND blasts through a gap in the Cordillera de Tilaran, a rugged mountain range that splits
northern Costa Rica in half, a female mantled howler monkey moves through the swaying trees of the forest
canopy.
A.
Ken Glander, a primatologist from Duke University, gazes into the canopy, tracking the female’s
movements. Holding a dart gun, he waits with infinite patience for the right moment to shoot. With great
care, Glander aims and fires. Hit in the rump, the monkey wobbles. This howler belongs to a population
that has lived for decades at Hacienda La Pacifica, a working cattle ranch in Guanacaste province. Other
native primates -white-faced capuchin monkeys and spider monkeys - once were common in this area, too,
but vanished after the Pan-American Highway was built nearby in the 1950s. Most of the surrounding land
was clear-cut for pasture.
B.
Howlers persist at La Pacifica, Glander explains, because they are leafeaters. They eat fruit, when
it’s available but, unlike capuchin and spider monkeys, do not depend on large areas of fruiting trees.
“Howlers can survive anyplace you have half a dozen trees, because their eating habits are so flexible,” he
says. In forests, life is an arms race between trees and the myriad creatures that feed on leaves. Plants have
evolved a variety of chemical defenses, ranging from bad-tasting tannins, which bind with plant-produced
nutrients, rendering them indigestible, to deadly poisons, such as alkaloids and cyanide.
C.
All primates, including humans, have some ability to handle plant toxins. “We can detoxify a
dangerous poison known as caffeine, which is deadly to a lot of animals:” Glander says. For leaf-eaters,
long-term exposure to a specific plant toxin can increase their ability to defuse the poison and absorb the leaf
nutrients. The leaves that grow in regenerating forests, like those at La Pacifica, are actually more howler
friendly than those produced by the undisturbed, centuries-old trees that survive farther south, in the
Amazon Basin. In younger forests, trees put most of their limited energy into growing wood, leaves and
fruit, so they produce much lower levels of toxin than do well-established, old-growth trees.
D.
The value of maturing forests to primates is a subject of study at Santa Rosa National Park, about
35 miles northwest of Hacienda La Pacifica. The park hosts populations not only of mantled howlers but
also of white-faced capuchins and spider monkeys. Yet the forests there are young, most of them less than
50 years old. Capuchins were the first to begin using the reborn forests, when the trees were as young as 14
years. Howlers, larger and heavier than capuchins, need somewhat older trees, with limbs that can support
their greater body weight. A working ranch at Hacienda La Pacifica also explain their population boom in
Santa Rosa. “Howlers are more resilient than capuchins and spider monkeys for several reasons,” Fedigan
explains. “They can live within a small home range, as long as the trees have the right food for them. Spider
monkeys, on the other hand, occupy a huge home range, so they can’t make it in fragmented habitat.”
E.
Howlers also reproduce faster than do other monkey species in the area. Capuchins don’t bear their
first young until about 7 years old, and spider monkeys do so even later, but howlers give birth for the first
time at about 3.5 years of age. Also, while a female spider monkey will have a baby about once every four
years, well-fed howlers can produce an infant every two years.
F.
The leaves howlers eat hold plenty of water, so the monkeys can survive away from open streams
and water holes. This ability gives them a real advantage over capuchin and spider monkeys, which have
suffered during the long, ongoing drought in Guanacaste.
