Passage 1

Ecuador, in South America, is home to 417 types of frogs and toads. Many of these species, or types of frogs, are at risk of dying out. In the last 50 years, many amphibian species have gone extinct. Salamanders, frogs, and toads are all amphibians. Amphibians are animals that spend part of their life in water and part on land, and have backbones. Amphibians must live near water. Amphibians are in trouble because their habitat is being destroyed as trees are being cut down to make room for farms and roads. Amphibians also absorb pollution easily, because they breathe through their skin. Amphibians are usually the first to disappear when an environment is under threat from pollution. Due to pollution, some frogs are born with deformed, or wrongly shaped, body parts, such as extra legs and eyes. Frogs with deformed body parts are a clue for scientists that an environment is suffering. Between the destruction of their habitats and risks to frogs from pollution, frogs are at risk of endangerment and extinction. 

Scientists are working to save amphibians from their plight. Scientists want the government to pass laws that protect amphibian habitats and limit pollution. 

Passage 2

My name is Maria and I am an amphibian conservation biologist. My job is to protect amphibians and their natural habitats, develop educational programs and exhibits to engage the public about amphibian conservation, and research to develop tools that will allow scientists to reintroduce amphibians back into the wild. Conservation biologists are scientists who study and protect animals and their environments.  I work in a zoo, but I often travel to places like Ecuador or Brazil to observe a variety of amphibians in their natural habitats. Brazil, for example, has 1,022 different types of frogs, toads and salamanders! In my work at the zoo, I specialize in only a small portion of that number. Here in the zoo, we have many amphibians in our care because some or all of their natural habitats were destroyed.  We are not alone in our work to protect amphibians. Many people, in many kinds of jobs, are helping protect amphibians and their habitats. I partner with other scientists and lawyers, like my friend Fernanda,  to help create laws that best support the conservation, or protection, of amphibians. Fernanda is an environmental lawyer who works to create laws like the Endangered Species Act that protect wildlife and their homes. She, in turn, needs to partner with government workers who can lobby and vote to help get laws passed. Together, our goal is to work together to build a world where these amphibians have safe space to live outside of the zoo, in their natural habitat, protected from pollution or loss of space. We are working with a facility in Brazil to build protected space for amphibians to be released from the zoo and into a space where they can thrive.

Adapted from The Ants and the Grasshopper by Aesop (620-560 BCE)

One bright day in late autumn, a family of Ants was bustling about in the warm sunshine, drying out the grain they had stored up during the summer, when a starving Grasshopper, his fiddle under his arm, came up and humbly begged for a bite to eat.

"What!" cried the Ants in surprise, "haven't you stored anything away for the winter? What in the world were you doing all last summer?"

"I didn't have time to store up any food," whined the Grasshopper; "I was so busy making music that before I knew it, the summer was gone."

The Ants shrugged their shoulders in disgust.

"Making music, were you?" they cried. "Very well; now dance!" And they turned their backs on the Grasshopper and went on with their work.

Adapted from Aesop’s The Lion and the Mouse (620-560 BCE)

A Lion lay asleep in the forest, his great head resting on his paws. A timid little Mouse came upon him unexpectedly, and in her fright and haste to get away, ran across Lion's nose. Roused from his nap, the Lion laid his huge paw angrily on the tiny creature to kill her.

"Spare me!" begged the poor Mouse. "Please let me go, and someday I will surely repay you."

The Lion was much amused to think that a Mouse could ever help him. But he was generous and finally let the Mouse go.

Some days later, while stalking his prey in the forest, the Lion was caught in the toils of a hunter's net. Unable to free himself, he filled the forest with his angry roaring. The Mouse knew the voice and quickly found the Lion struggling in the net. Running to one of the great ropes that bound him, she gnawed it until it parted, and soon the Lion was free.

"You laughed when I said I would repay you," said the Mouse. "Now, you see that even a Mouse can help a Lion."

Text 1: 

One clear advantage of selling goods online is that smaller markets can be served without the seller needing to invest in high inventory costs. Recordings of classical music, for example, are increasingly hard to find at the larger music chains. Now the classical music lover can locate nearly any classical CD in print on the Internet. 

Also, forward-thinking artists without national followings have made their music available on personal sites or through services that provide the musicians with a more generous share of profits than that offered by the large record labels. For some, this has resulted in increased sales volume, greater return on investment, greater control of the product, and a more direct connection with their fan base. 

Major orchestras and record labels have taken note and have created websites where one can purchase individual tracks, full CDs, archival recordings, and even music exclusively made available for online downloads. Some symphony orchestras now include the price of admission to a concert and the right to download a recording of the concert afterward. Other services allow the listener unlimited streaming or downloading for a monthly fee.

Text 2:

One disadvantage of selling goods online is that large online retailers can crush smaller retailers. Big corporations that sell online have access to more goods, which brings each item's cost down exponentially. They place larger orders and can carry more varieties of products so they may be able to satisfy more customers.

Just about anything can be found online, so it takes away the fun of the hunt. Digging through vintage record bins, combing through racks of clothing, or spending a day out shopping with friends is reduced to a few clicks online and waiting 3-5 business days for the package to arrive. Small businesses are losing foot traffic to their stores and facing declining sales when a big box store can beat their price with a cheaper imported good.

Musicians, for example, may have CDs to sell after a performance, but when people can download the single song they like, or it can be listened to on a streaming service, the artist can lose out on those sales. Many artists don’t produce a tangible good anymore and make their goods available for digital download or purchase.

How do these authors present their information similarly or differently?

Text 1:

Genetic investigations into the origins of human life most often focus on mitochondrial DNA. As opposed to nuclear DNA, mitochondrial DNA is transmitted only from the mother. This allows for the tracing of mutations that arise independently of changes that occur because of the combining of the mother’s and father’s DNA. As useful as this is, the high mutation rate of mitochondrial DNA allows scientists to look at only relatively recent prehistory. 

Text 2:

Nuclear DNA, on the other hand, has a low mutation rate, making it ideal for looking into the more distant past. Studying the nuclear DNA of fossils now shows a substantial decrease in population size in Europe and Asia approximately 50—80 thousand years ago. No such decrease happened in Africa. This supports the idea that migrants from Africa replaced all previous humans and did not interbreed with earlier migrants.

Passage 2: Unwanted Guests: The Dangers of Invasive Species (2016)

Groups of different animals affect one another in the natural world. For example, imagine that wolves and deer live in an area. A certain number of wolves need to eat a certain number of deer to survive. This keeps the population of the deer from getting too big. Similarly, the deer eat grass and vegetation. If there were more deer, they’d need to eat more grass.

The natural world is full of balances like these. Unfortunately, sometimes these balances are upset by invasive species. An invasive species is an animal or plant that has moved or been moved from its original environment to a new one. It has established a stable population there that is causing problems. Invasive species don’t cause problems in their original environments because they are kept in check by other plants and animals. In new environments, though, they have nothing stopping them from taking over.

One example of an invasive species is the zebra mussel. This animal originally only lived near Russia. Zebra mussels got into the Great Lakes by attaching themselves to the bottoms of ships. They now live in the Great Lakes too, where they upset the ecosystem. Zebra mussels eat algae, but so do fish. Many fish die as a result of there not being enough algae for all the animals to eat.

Plants can be invasive species too. Another example of an invasive species is the kudzu vine. Humans introduced the plant to the United States on purpose. Farmers were encouraged to grow it to protect their soil. Since then, it has gotten out of control. It now covers large parts of the South, outcompeting native plants for resources like water and sunlight.

Invasive species can cause environmental problems that are very difficult to fix. Because of this, it’s important to rethink introducing any species to a new environment. It’s also important to check to make sure when traveling that you are not bringing any plants or animals with you!
