Life Cycle

In the dark Amazon forest, plants fight for light The strangler fig is one of the best competitors in the rainforest Read on

• Sticky strangler fig seeds are dropped by birds and fall into cracks

of a host tree’s bark in the treetops They “start at the top,” and don’t mess around growing from the soil

on the forest floor

• Taking advantage of the greater sunlight, air, and water in the treetops, the sapling quickly grows

STRANGLER FIG BRINGS LIFE AND DEATH TO THE AMAZON RAINFOREST

by Patty Claudio

he Amazon Rainforest in South America

is one of the most important forests in the world, and fig trees are one of the most important species in tropical rainforests Of the 150 fig species in the Amazon, one

of the most successful survivors is the strangler fig

If you’re thinking this species sounds a little scary,

you’re not wrong In Peru, strangler figs are called

matapalos (tree killers).

FUN FACTS

wasp benefit The wasps are about two millimeters long, and enter at the bottom of the fig fruit Once inside, they pollinate the flowers and also reproduce Without these special wasps, there would be no seeds

And without the figs, there would be

no wasps

Ecological Importance

Although they cause death to the host tree, strangler figs also provide life to many other animals in the rainforest

The nooks and crannies in its hollow trunk provide important habitat to insects, rodents, bats, reptiles, amphibians, and birds

Many scientists consider strangler figs a keystone species, an organism that helps hold a system together

This is because figs bear fruit several times a year Different species of figs fruit at different times so there is always a supply of food for various animals, even if other food is scarce

And once herbivores eat fruit, they become prey for predators in the

• Some leaves and branches reach

upward toward the light Other “aerial

roots” travel downward toward the soil

• As they grow downward, the roots

of the strangler fig wrap themselves

around the host tree They form a

criss-cross frame that completely surrounds

the host’s trunk

• Once the roots reach the ground,

the strangler steals the nutrients and

moisture that the host tree depended

upon for its survival

• Meanwhile, at the top of the tree,

the strangler fig’s own leaves spread

upward, overshadowing the host’s

crown The fig’s leaves take all of the

life-giving sunlight

• The host tree dies

• The strangler fig is now large and

strong enough to stand on its own Its

hollow trunk is the only clue that there

was ever a host tree

A Fig Is Born

If you think that being a destructive

parasite that kills its host is unusual,

things are about to get even weirder

Many fig species have a symbiotic

relationship with a tiny pollinator wasp

That means that both the fig tree and

rainforest food web

There are two other positive characteristics of the fig First, the species seems to be maintaining stable populations So, the International Union for Conservation (IUCN) does not list it

as being threatened or endangered Secondly, strangler figs anchor their host trees during tropical cyclones Thus, the killer fig can also act as a bodyguard

Though some of the strangler fig’s survival strategies are shady

by human standards, it is one of the most extraordinary and successful trees found in the forests

of South America

Banyan trees are considered sacred by those who follow the Hindu faith.

trees meet and form a shade, must cover at least 10 percent of the land below

In comparison, woods refer to an area of land covered by growing trees, but it is smaller than a forest This space does not have to meet the same requirements as a forest However, it can also have critters that inhabit the space A forest

It is not unusual that the words

“forest” and “woods” are often swapped, either in conversation or

in writing Although the two areas are similar in some ways, they have distinct differences For instance, a forest is at least 1.24 acres in size In

a forest, the trees are at least 16 feet tall The tree canopy, which is the layer overhead where the tops of

forest is a fascinating place, filled with trees and a variety

of interesting creatures, too

It is a mysterious spot, a land all its own, and it offers the potential for exciting adventures But what exactly makes a forest a forest?

way to spend time

organisms Above the floor is the understory layer, located under the leaves but above the ground This layer may be damp, and plants here adapt to living in shady conditions The canopy layer of the forest is the area where the tree tops meet, forming a thick overhead curtain Just above the canopy is the emergent layer Here, gigantic trees poke out

generally has a thicker canopy cover,

while the density of trees in the woods

is sparser In many ways woods are a

miniature version of a forest

Different varieties of forests exist

throughout the world They fall into

the categories of boreal, temperature,

and tropical

A boreal forest, also known as

taiga, is located the farthest north and

experiences long, cold winters Boreal

forests span eight countries: Canada,

China, Finland, Japan, Norway, Russia,

Sweden, and the United States

In contrast to a boreal forest, a

tropical forest exists along the

equator and has high temperatures

and long growing seasons Tropical

forests can be found in Central and

South America, western and central

Africa, western India, southeast Asia,

Australia, and the island of New

Guinea The rainforest falls into the

category of a tropical forest

Finally, a temperate forest goes

through four distinct seasons, so the temperatures fluctuate throughout the year They exist in eastern North America, northeast Asia, and central and western Europe

Regardless of the type of forest or its geographical location, a forest is comprised of several layers First, there is the forest floor, a thick, rich carpet of soil, fungi, insects, and

The forest in the Oulanka National Park in Finland is an example of a boreal forest.

Tropical forests can be found in Southeast Asia

A walk in the woods? If it’s more than 1.24 acres in size with trees at least 16 feet fall, it’s a walk in the forest

A poplar place for a hike.

Trang 13

In the temperate forest, you may encounter deer, squirrels, snakes, lizards, and turtles The European mink is an animal exclusive to this forest

A tropical forest is home to many interesting creatures There are sloths, eagles, gorillas, and frogs, for example The emperor tamarin, a quirky-looking species

of monkey that appears to have an elongated moustache, also lives in this type of forest

Any forest is an essential part

of the earth’s ecosystem A forest produces oxygen, serves as home

to many living things, and houses medicinal plants and ingredients, too Every forest plays an important role in keeping our waterways clean and healthy, as well But perhaps one of the greatest gifts

a forest provides is an inspiring, recreational area for all to admire, use, and enjoy

above the canopy, and this

layer is home to a variety

of birds and insects

Perhaps the most

exciting component of any

forest is the creatures that

nest there They are essentially

the faces of the forest, and they

can vary greatly depending upon

the location Inhabitants of each

type of forest adapt to the specific

temperatures and conditions of their

home so they may continue to survive

and thrive

Each type of forest can be filled

with animals, birds, reptiles, insects,

and other organisms

Species found in a boreal forest include moose, snowshoe hare, beaver, black bear, yellow perch, and northern pike At risk species such as caribou and wood bison live here, too The American marten, also known as American pine marten, is an animal unique

to the boreal forest

Fall foliage can be found in temperate forests, like this one in Czechia

ight out of ten animals that live on land make their homes in forests Trees provide the air we breathe and the wood we use Though protecting our woodlands seems like a no-brainer, forests are being cut down at

an alarming rate for timber, mining, and growing crops Read on to find out about five species whose futures depend on the trees These fascinating animals are all critically

endangered and struggling to survive They are the tree kangaroo, giant panda, saola, orangutan, and African forest elephant

12

Trang 15

Tree Kangaroo

These unusual koala/sloth/monkey/bear-like kangaroos live in

trees in the mountain forests of tropical New Guinea They are

marsupials (animals that carry their young in pouches) with arms

that are longer and stronger than their land-loving kangaroo

cousins Their movements in the trees are an odd mix of climbing

and hopping The tree kangaroo eats mostly leaves and fruit from

trees and the ground

Recently, a rare type of tree kangaroo, known as the wondiwoi

tree-kangaroo (Dendrolagus mayri) was rediscovered It was first

sighted in 1928 by a biologist who shot it and sent its pelt to a

London museum No other members of the species were found for

90 years Fast forward to 2018 Michael Smith, an Englishman who

traveled the world looking for rare plants, heard tales of the

mysterious animal and organized an expedition to search for it In

a dense bamboo forest, high in the mountains of Papua, his team

finally spotted the elusive tree kangaroo—90 feet up in a tree

Smith struggled to focus on it and shot it—with his camera, of

course (Note the improved research techniques since the “shoot

first, study later,” technique used 100 years ago.) Scientists hope to

return to collect dung or a small piece of ear tissue to extract DNA

and compare with DNA from the pelt collected in 1928

The future of the wondiwoi tree-kangaroo is uncertain, as there

is already a proposal for a gold mine in the park

Trang 16

Saola

One of the most threatened animals on the planet is

an antelope called the saola (Pseudoryx nghetinhensis)

A cousin to the cow, it is found only in the lowland

Annamite Mountains of Laos and Vietnam Though it

has two horns, the saola is often called the Asian

unicorn because it is so rare Scientists estimate that

there may be only 25 individuals alive

The saola was discovered in 1992, when a scientific

team was surveying the animals that lived in a nature

reserve on the Vietnam/Laos border While in the

home of a local hunter, a team member came across a

pair of horns that were unlike any others from

Southeast Asia Eventually, more horns ( from recent

kills) and a full skin were found and determined to be

a distinct species

Giant Panda

Like the tree kangaroo, the giant panda also makes its home in dense bamboo forests—not in Indonesia, but in the high, rainy mountains of south central China These quick facts may help you understand the panda

1 Pandas are BIG eaters Each day they fill their tummies for up to 12 hours, digesting about 26 pounds of bamboo (the main staple of their diets)

2 Panda’s scientific name, Ailuropoda

melanoleuca, means “black and white cat-foot.”

3 An adult female panda weighs 200 pounds

4 Sometimes male pandas relax by doing handstands against trees

5 Pandas play an important role in the bamboo forests by spreading seeds

14

Trang 17

Orangutan

The name, orangutan (scientific

genus, Pongo), means “man of the

forest” in the Malay language This is fitting for the world’s largest tree-climbing mammal With arms longer than its legs and grasping hands and feet for climbing, orangutans are well adapted for life in the trees of Borneo and Sumatra Orangutans have long orange hair that sparsely covers their bodies, large jaws, and flat noses on their concave faces Like pandas, they are forest gardeners who spread seeds in their habitats

African Forest Elephant

African forest elephants (Loxodonta cyclotis) live in the dense rainforests of west and central Africa

Their ears are more oval-shaped, they have straighter downward-pointing tusks, and they are not as big as African savanna elephants Despite their “smaller” size (the mere height of a basketball hoop and the weight of an ambulance), they have huge appetites for fruits from many tree species Like pandas and orangutans, they are mega forest gardeners that help spread the seeds of many

rainforest trees to keep their habitats healthy and biodiverse The range of the African forest

elephant has shrunk from 3 million square miles to 1 million square miles since 1979, and poaching has killed 65% of their population from 2002-2013

FAST FACT

Kangaroo expert, Roger Martin, of James Cook University in Queensland Australia, has a

solution to help these threatened animals He suggests that “if we provide habitat for animals

and otherwise leave them alone, then they will get on just fine.” If only it were so simple

his is a story of yesterday, today, and tomorrow Over the past 100 million years, dense forests grew to cover more than half the Earth As humans began to

flourish, we cleared the forests for our own uses Today,

rainforests the size of 20 football fields are cut down every minute

At this rate, we will have no rainforests left at the end of the century, according to NASA

Trang 20

What is a rainforest?

A rainforest is an area of tall trees that

gets 80 to 400 inches of rainfall a year

Also known as jungles, rainforests

contain thick, tangled canopies of

plants, vines, and small trees

Why are rainforests important?

➜ Rainforests are home to more than

half the known plant and animal

species on the planet When the

forests are cleared, they all die

➜ Trees help absorb the harmful

carbon dioxide in the atmosphere

and provide the oxygen that we

need to breathe

➜ More than 25% of our medicines

come from rainforest plants, but

we have only explored 1% of the

plants available Medicines also

come from rainforest animal

sources, such as green algae from

a sloth’s back to treat cancer and

malaria, and snake venom for high

blood pressure

➜ Rainforests soak up a

lot of rain, filter it through forest floors, and supply water to streams and rivers

They also help prevent erosion, which washes away soil and causes floods

➜ They are home to

indigenous people, native groups who lived in the rainforests before colonists came

Where are the rainforests?

Two of the largest rainforests are the Amazon Rainforest in South America and the Congo Rainforest in Africa

People of the Amazon Rainforest

The Yanomami (yah-no-mah-mee) are a group who live in the largest rainforest in the world—Brazil’s

Amazon Rainforest They are somewhat isolated groups of hunter-gatherers who cultivate small gardens

Families live in a yanos (large

community house) that circles a central area used for feasts, rituals, and games The Yanomami believe everyone is equal They make group decisions by having debates in which everyone gets a say

The Yanomami and rainforest are both threatened by mining,

deforestation, fires, and climate change Thousands of gold miners

to make their living, but the demand for resources is getting greater with the increase of population.

Solutions

➜ Say no to foods that contain

palm oil Look at the labels

of cake, chocolate, margarine, and cosmetics

➜ Avoid buying mahogany,

rosewood, and ebony when you are buying furniture

➜ Eat less meat Rainforests are

being cleared to make room for grazing cattle so that we can eat beef burgers If we eat a bit less meat, that’s less pressure on the rainforest

➜ Plant trees!

➜ Support rainforest organizations.

➜ Talk about the rainforest with

your friends and family The more they know about this rich biome, the more they’ll want to protect it, too!

As the Lorax says, “unless someone like you cares a whole awful lot, nothing is going to get better It’s not.”

work illegally on Yanomami land

They cut down trees, transmit deadly diseases like malaria and measles, and pollute the rivers with mercury

Some Yanomami who live by gold mines have dangerously high levels of mercury in their bodies Cattle ranchers are cutting down trees to make pastures for grazing Land that

is cleared of trees is more likely to catch fire, which burns millions more acres of rainforest Warmer and dryer conditions brought on by climate change are making the fires even more devastating Finally, it is difficult for the government to make and enforce laws to protect the people in areas where natural resources are in such high demand

Elsewhere in the Amazon, dams cause flooding, block fish migration and the flow of nutrients, and further deforest the land

People of the Congo Rainforest

There are about 40,000 Mbuti living in the Congo Rainforest They are nomadic hunter-gatherers who make simple beehive-shaped structures using stick frames covered by leaves Mbuti pygmies hunt and use up resources in

an area, then move to a different settlement every two to four weeks

Their food supply is threatened by deforestation, mining, and political unrest The Congo Basin is loaded with natural resources such as wood, oil, minerals (diamonds, gold and coltan used to make cell phones) Trees are being cut down to make way for palm oil plantations, for use as timber,
