Exploring ecoregions: if Earth were a giant jigsaw puzzle, one way to see its pieces could be as countries. But scientists also see the pieces as different ecological areas, or ecoregions.


Exploring ecoregions This is a list of ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions.

The terrestrial scheme divides the Earth's land surface into 8 terrestrial ecozones, containing 867 smaller ecoregions.
: if Earth were a giant jigsaw puzzle, one way to see its pieces could be as countries. But scientists also see the pieces as different ecological areas, or ecoregions. Ecoregions are large geographical areas defined by their distinctive natural features such as soil type, climate, and plant and animal communities. Scientists have mapped out more than 1,000 different ecoregions on Earth. Today, many of these ecoregions are in danger because of pollution, habitat loss, and other problems. Here are three of the richest and most threatened ecoregions. (Scholastic Science World)

What's An Ecoregion?

Wherever we live, we live in an ecoregion. An ecoregion is a relatively large unit of land that is characterized by a distinctive climate, ecological features, and plant and animal communities. Scientists at World Wildlife Fund and other conservation organizations have mapped the world into more than 1,000 different ecoregions, all filled with diverse species (kinds of organisms) and habitats (where organisms live), which are valuable to the people who live there. But some ecoregions are considered higher priority for conservation action than others. Why? Take a closer look at three characteristics of the South American Atlantic Forest ecoregion to find out.

PART A: One question scientists ask about an ecoregion is, "How many different species of plants and animals Plants and Animals are a Canadian indie-rock band from Montreal, comprised of guitarist-vocalists Warren Spicer and Nic Basque, and drummer-vocalist Matthew Woodley.[1] They are signed to Secret City Records.  live there?"

* The Atlantic Forest is extremely diverse. It's home to 5 percent of the world's animal species and 7 percent of the world's plant species.

* In a 1 hectare (2.5 acres) plot, scientists counted 450 different species of trees.

PART B: Another question scientists ask is, "How unique are the life forms in the ecoregion?" In other words Adv. 1. in other words - otherwise stated; "in other words, we are broke"
put differently
, are there endemic species--ones that naturally occur in only one area or region?

[ILLUSTRATION OMITTED]

PART C: Scientists also ask, "How threatened is this ecoregion?" If an ecoregion full of unique life is disappearing quickly, we need to act to help save it.

Directions: Use the data supplied to find the correct answers.

1. If there are an estimated 270,000 plant species on Earth, approximately how many live in the Atlantic Forest? a. 890 b. 8,900 c. 18,900

2.

The bustling Brazilian cities of Sao Paulo and Rio de Janeiro Rio de Janeiro, city, Brazil
Rio de Janeiro (rē`ō də zhänā`rō, Port. rē` thĭ zhənĕē`r
 lie in the heart of the Atlantic Forest ecoregion. More than 2,589,998 square kilometers (1,000,000 square miles) of tropical rainforests once covered this region; its rich diversity of plant and animal species spread over parts of Brazil, Paraguay, and Argentina. Now, cities, factories, and farms have replaced most of this wild habitat. Less than 7 percent of the original forest remains.

Many people in this ecoregion recognize that protecting the remaining patches of the Atlantic Forest is essential for both sustaining rare species and preserving the quality of human life. Forests boost water supplies, stabilize soils, and pump the atmosphere with oxygen essential for breathing. Because the remaining forest is extremely fragmented, animal populations are isolated, making breeding difficult. In addition, limited resources challenge their survival. One aim of World Wildlife Fund's "Pennies for the Planet" program is to help create corridors, or protected areas, to link existing forest reserves.

What lives inside a rainforest? Plenty! Each layer teems with life. Study the diagram (right) to answer the following questions in complete sentences.

1. In which layer of the forest are rivers found?--

2. In which layer of the forest do sloths spend most of their time?--

3. Jaguars sometimes eat tapirs. Based on this information, in which two layers do jaguars spend time?--and--

4. Which layer is the windiest?--

Emergent Layer: Trees in the emergent layer grow high above the leafy tops of other trees, reaching heights of up to 61 meters (200 feet). Bathed in bright sunlight much of the time, this layer also undergoes extreme shifts in temperature, wind, and rainfall. Ariel toucans, white-lined bats, and many colorful butterflies fly within this high zone.

Canopy: Lots of sunlight reaches the tangle of vines, leaves, and branches of the canopy layer, which rises to about 40 meters (150 feet). Here tiny primates called tamarins feast on fruit and insects, slow-moving sloths hang upside down, and blue-bellied parrots perch on branches.

Everglades and South Florida

If you travel from the northern edge of the Everglades to the southern tip of the Florida Keys Florida Keys, chain of coral and limestone islands and reefs, c.150 mi (240 km) long, extending from Virginia Key, S of Miami Beach, to Key West, and forming the southern extremity of Florida.  island chain, you would encounter a number of wild and impressive habitats. The Everglades is a "river of grass" more than 80-kilometers (50-miles) wide and 322-km (200-mi) long, but rarely more than 61-centimeters (2-feet) deep. Here, rare Florida panthers pad through the forests while alligators cruise the shallows. Birds like roseate spoonbills, egrets, and ibises wade in the water, and wood storks congregate in the treetops. Just off the coast in Florida Bay Florida Bay is the shallow bay located between the southern end of the Florida mainland (the Florida Everglades) and the Florida Keys. Nearly all of Florida Bay is included in Everglades National Park. , rotund sea cows call manatees swim and feast on sea grasses. And the world's third largest coral reef--where thousands of fish species, lobsters, sea turtles, and more--call the Florida Keys home. The Keys are also the only place on Earth where you can see tiny Key deer and the elusive American crocodile. But, if you've visited southern Florida, you know that many people live in growing cities such as Miami and Fort Lauderdale Fort Lauderdale (lô`dərdāl), residential, commercial, and resort city (1990 pop. 149,377), seat of Broward co., SE Fla., on the Atlantic coast; settled around a fort built (c.1837) in the Seminole War, inc. 1911. . In the last century, people have altered this ecoregion by developing land, changing the flow of fresh water to ensure a steady supply for people and their crops, and polluting the environment. Because of these changes, many plant and animal species indigenous (native) to this area are threatened or endangered.

New plans are underway to help restore the Everglades and South Florida ecoregion. World Wildlife Fund's "Pennies for the Planet" program will aid conservation and research efforts, including a student water quality monitoring program, studies of roseate spoonbills and other species in need, and a project to recover lost fish traps--which can float loose for years, killing any species they catch.

To learn more about how an imbalanced ecosystem threatens the life within, study this diagram illustrating a portion of the Everglades food web. Arrows point from things that are eaten to the creatures that eat them. Then answer the questions below in complete sentences.

You Need:

a simple map of the area you plan to survey, such as your schoolyard or nearby park * paper and pencils * magnifying glasses * field guides

To Do:

1. Select an area to study. Then form small survey teams. Organize your group to maximize efficiency; for example, you might want to assign different members to different parts of your survey area, or to different organisms, such as insects, plants, mammals, and so on.

2. Identify every living thing and signs of living things you see (see Animal Signs for hints). When you see something, make a note of its location. Don't worry if I you don't know Don't know (DK, DKed)

 the organism's name. Simply sketch it and label your drawing with a description, such as "shiny black bug" or "tall yellow flower" or "insect that ate the maple leaves."

3. After 30 minutes, return to class and compare your results. Then discuss the following:

* How many different species did each group find? Is that more or less than you expected? Have you noticed all these organisms before?

* Are the organisms evenly distributed across your survey area? Can you guess why or why not?

* Do you expect to get different results if you did this survey again? Explain.

* In some parts of the world, wildlife habitats are diminishing very quickly because of environmental changes such as clearing forests to make way for farms and cities. Why do you think scientists find rapid assessments so useful?

4. Pool your class's findings to create a mini field guide to showcase your area's biodiversity. Use existing field guides to help you find the scientific and common names of the organisms.

Miombo Woodlands

Visitors to the Miombo Woodlands ecoregion are often amazed by sightings of incredible wildlife: herds of elephants yanking down branches with their trunks, cheetahs slinking through tall grasslands, warthogs zipping by with tails in the air, wattled cranes gathering in the wetlands, and rare wild dog families resting in the shade. This southern African landscape is characterized by oak-like trees that the indigenous Bantu people call miombo and mopane This article is about the tree. For other uses of mopane or mopani, see mopani (disambiguation).

The mopane or mopani (Colophospermum mopane
.

The animals of this ecoregion depend on local woodlands to keep them alive. But for a growing human population of more than 40 million people, these woodlands are also a key source of food and fuel. Around 5,180 square kilometers (2,000 square miles) of woodlands are cleared each year for agriculture. Due to these shrinking woodlands, many animals' natural habitats become fragmented.

Conservationists are looking for sustainable ways to keep woodlands healthy for both human needs and animal survival. In other words, they are trying to meet the needs of the present without diminishing the ability of people, other species, and future generations to survive. World Wildlife Fund's "Pennies for the Planet" program will help create a community-managed corridor, or protected link, to connect two existing but separated wilderness preserves (protected areas). This would give animals more freedom of movement to find food sources as well as mates. And careful monitoring would provide local human communities areas to gather resources wisely.

Who depends on the Miombo Woodlands? Many herbivores, or plant-eating animals. Some are grazers (grass eaters) and some are browsers (animals that eat the leaves of shrubs and trees). And the less picky pick·y
