Earth’s temperatures are getting warmer. In fact, sixteen of the seventeen hottest years on record have occurred since the year 2000. These warmer temperatures are driving larger, long-term changes in our planet’s weather and climate. Scientists refer to these changes as “climate change.”
In a few places, climate change might be welcome, but around the world, warmer temperatures and other changes are leading to a host of problems from rising sea levels to more extreme weather events and the spread of harmful human diseases.
Professor Scott Mills, from the University of Montana, wanted to see how climate change might be affecting one particular animal called the snowshoe hare.
Snowshoe hares live in regions of North America that receive snow every winter. The hares, in fact, change their coat color from brown to white and back again every year. This helps camouflage them against their background—and hides them from the eyes of lynx, owls, and other hungry predators.
Here’s the thing: snowshoe hares can’t choose when they molt, or change their coat color. Molt timing is controlled by their genes, which are part of the DNA inside their bodies. If a hare’s genes make it molt to white in October, but snow doesn’t fall until December, the hare will stick out like a light bulb against the brown earth. And that’s a problem. Why? Because almost everywhere on earth, the length of time with snow on the ground is growing shorter and shorter.
To find out if shorter winters might harm hare populations, Scott and his team spent three years tagging and following hares. They measured how many were born, how many died, and what they died from. They also recorded whether the hares were matched or mismatched against their backgrounds.
They discovered that predators killed mismatched hares significantly more often than hares whose coats match their backgrounds. Scott and his team also calculated that over the next one hundred years, this greater mortality, or death rate, could lead to the decline or disappearance of many snowshoe hare populations.
The good news? Different hares molt at different times. This may help some hare populations adapt to shorter winters and longer periods without snow.
Hares are not the only animals affected by shorter winters. More than twenty species of animals including lemmings, weasels, hamsters, and Arctic foxes change their coat colors every year. Scott’s research helps us predict what might happen to these animals—and decide what we can do to protect them.
Scott’s discoveries about Montana snowshoe hares, together with experts’ predictions about our future climate, indicate that hares will be mismatched between 5-½ and 10 weeks by the end of this century.
Before tagging and putting a radio collar on a snowshoe hare, Professor Mills and his team must weigh and measure it.
This snowshoe hare has been tagged and fitted with a radio collar—and is now ready to help scientists learn more about snowshoe hare survival.

Besides serving as popular prey for predators, snowshoe hares are irresistibly cute. This is a young hare, also called a leveret.

Have you ever wanted to tell your life's story? It's not as easy as you think. Here are some tips that can make it easier.
First, realize that you can't tell your whole story. Not only will you bore your readers, you'll probably give up before you write a quarter of it. Instead, choose a theme—something that's been important to you and that interests you about your life. Here are a few examples:
* The story of you and your favorite hobby.
* Your experiences with your favorite—or least favorite—pet.
* Fun times you've had with your dad, mom, or best friend.
* The three scariest things you ever did.
* Your best/worst school year.
In my memoir, Snakes, Alligators, and Broken Hearts—Journeys of a Biologist's Son, I decided to focus mostly on my relationship and adventures with my dad. Narrowing down my story not only led to a better story, it made the writing process much less overwhelming. This kind of "slice" of a life is called a memoir. In contrast, when someone tries to tell their complete story, it's called an autobiography. Usually, the only people who write autobiographies have invented electricity or landed on the moon—or they are running for president!
A second tip for telling your story is to pick out certain characters and let the reader get to know them. When writing my memoir, I could have said a little bit about a lot of different people in my life. Instead, I chose just a few and tried to tell more about them. This lets readers get to know the people in your story—and care about your story more.
One last tip is to leave out the boring stuff. When you start writing, it's tempting to include every detail. Instead, start your story where it really gets interesting. For instance, don't begin with, "On my first day of school, I walked to class." Instead, you might start with, "When I looked in the cage, I realized that our twelve-foot long boa constrictor had escaped!" Just because it's your story doesn't mean it shouldn't have a good plot and plenty of action. Focus on topics you'd like to read about—even if you didn't know you!
After reading these tips, you might be asking yourself, "Can I write more than one memoir?" The answer: absolutely! So dig in, have fun, and tell your story. You, your friends, and family will be glad you did.
To help your story be more interesting, focus on one thing. For my memoir, I focused on my relationship and adventures with my dad. Here, he is graduating with his doctorate degree from U.C. Santa Barbara
Both my dad and I loved reptiles, so I told a lot of stories about them in my memoir.
During the long summers with my dad, I often hung out at his laboratory. One summer I helped him build this giant plankton net that he used to sample animals in the Gulf of Mexico.
My dog, Puppy, helped get me through the difficulty of my parents’ divorce, so Puppy became a primary character in my book. Man, I wish I still had that shirt!

"Connecting Scientists and Kids”
Only you can prevent forest fires! At least that’s what Smokey Bear taught me growing up. His message? All forest fires are bad, and we’re helping nature by putting them all out.
Recently, I met a scientist who’s made me rethink this negative message about natural wildfires. His name is Dick Hutto and he’s a biology professor at the University of Montana. “There are two kinds of fires,” Dick explains. “The ones that burn down your house or kill your neighbor are bad, bad, bad. The other ones can be the greatest things in the world.”
To prove his point, Dick took me to the Black Mountain burn area, near my home in Missoula, Montana. A severe forest fire burned through this area only ten years ago, and thousands of blackened trees still stand like sentries across the landscape. Surprisingly, this charred landscape explodes with life. Tens of thousands of new tree saplings reach for the sky. Elk and deer graze on the fresh grass growing in the newly-opened areas. More than anything, the songs of birds fill the burned forest.
In his research, in fact, Dick discovered that dozens of bird species love fresh burn areas. In the West, 15 bird species prefer burned forests to all other habitats! Woodpeckers pave the way. As soon as a forest burns, legions of wood-boring beetles descend on the forest and lay their eggs in the dead trees. Three-toed, Hairy, and Black-backed Woodpeckers follow and begin devouring the newly-hatched beetle grubs. They also chisel out their own nest holes—holes that are used by Mountain Bluebirds, American Robins, Black-capped Chickadees, and many other species. Because of burned forests, these birds find food and shelter. They also find safety. How?
Green forests abound with squirrels and chipmunks—animals that feast on bird eggs. A severe forest fire, though, clears out the small mammals. That means that birds can raise their young much more safely.
But listen, don’t take my word for it—or even Dick Hutto’s.
To learn more about the benefits of fire, throw a water bottle, lunch, a bird guide, and a pair of binoculars in your backpack and go visit a burn area for yourself. You will be astonished by what you see. Take a notebook or a camera along, too. Part of the fun of discovering our planet is sharing what you see. By doing so you’ll help others realize the importance of natural wildfires and burned forest—and help create a healthier, more interesting world.
Sneed Collard III has written a book about the birds that thrive in burn areas. Fire Birds shows how dozens of bird species not only survive, but actually thrive in burned areas, depending on burns to create a unique and essential habitat that cannot be generated any other way.

Do you ever hear that sound while walking around outside? If you do, you are probably hearing the sound of a woodpecker. More than 200 kinds of woodpeckers are found on Earth and they live on every continent except Australia and Antarctica. They are not only some of our most beautiful birds—they are some of the most important.
Woodpeckers are especially adapted to pound, dig, and drill into wood. The main reason? To find food. Ants, beetle grubs, and other insects live under bark and inside dead wood, and woodpeckers have evolved to take advantage of this “food fest.” Woodpecker beaks are super sturdy, and the birds have extra-long, sticky tongues to probe into tiny holes and passageways. A woodpecker’s head has special shock absorbing features that keep the birds from getting brain damage while they are pounding away!
As they look for food, woodpeckers are also carving out holes to live in. This helps dozens of other kinds of birds. How? Because many cavity nesting birds need holes in which to sleep and nest, but almost none of these birds can excavate holes for themselves. By drilling holes, woodpeckers are helping bluebirds, house wrens, chickadees, titmice, and many other bird species. Even some mammals and reptiles take advantage of woodpecker holes!
About 22 species of woodpeckers live in the US and Canada. The most common is probably the Northern Flicker. Unlike most other woodpeckers, Northern Flickers spend a lot of time on the ground slurping up ants. In spring, they make raucous calls and like to drum on rain gutters, utility poles, and metal chimneys! Most woodpeckers use drumming to attract mates and shout, “This is my territory! Keep out!”
Downy Woodpeckers also adapt well to cities and neighborhoods. They are among the smallest woodpeckers and can survive almost anywhere there are trees.
Many other woodpeckers live only in certain regions or habitats of the US. Black-backed Woodpeckers live only in burned forests. Golden-fronted Woodpeckers are found mainly in Texas. White-headed Woodpeckers live only in high mountain areas of the West Coast.
Wherever you find them, woodpeckers are fun to watch and fascinating to learn about. The next time you see one, stop and observe it for a while. Take a moment to appreciate its behavior and how it makes our world a richer, more interesting place.

The Black-backed Woodpecker lives almost exclusively in burned forests where large dead trees are still standing.
Woodpeckers provide nesting holes for dozens of our favorite birds including this spectacular Mountain Bluebird.

Have you ever been asked to revise something that you wrote, but had trouble doing it? Maybe you didn’t know where to start? Maybe you thought you might actually make it worse than before? Maybe you thought it would be too hard?
Believe me, I get it. When I sit down to revise, I am often filled with fears about doing it. Over the years, though, I’ve come up with three simple steps that help take the fear out of revision. Let’s see how to use them when revising the most important chunk of writing—the paragraph.
When I revise a paragraph, my first step is to ask myself is “What’s this paragraph about?” Usually, I’ve already written a sentence that tells me. It’s called a thesis sentence. A thesis sentence can be something kind of loose such as “Skateboards rock,” or it can be specific such as “Yesterday, I had my best skateboard ride ever.” The point is that this sentence tells me what the rest of my paragraph needs to be about. When revising, I find it helpful to underline my thesis sentence.
Step Two is to make sure that my paragraph makes sense. Here, I check that every sentence helps prove or explain why my thesis sentence is true. I also make sure that none of my sentences are confusing. If they are, I revise them so they are easier to understand. I especially look for sentences that don’t really say anything, such as “Skateboards are, like, the best.” I’d either delete this sentence, or improve it to something like, “Skateboards provide great exercise.”
After my paragraph makes sense, I move on to Step Three: making my paragraph more fun. I replace boring verbs with more exciting ones. Instead of saying “My skateboard was fast,” I might write, “My skateboard hurtled down the ramp.” I put in better descriptions. I also might crack a joke, or throw in a simile such as “My skateboard carried me like a four-wheeled chariot”—or a metaphor, “My board launched me into the stratosphere.”
When tackling revision, I recommend having someone else read your writing aloud. That helps you spot problems. Even so, I don’t always nail a revision the first—or even the tenth—time. I revised this nonfiction minute more than a dozen times! The important thing is to not let your fears overwhelm you. Remember that revision is simply the process of you saying what you want to say.
What happens when a bestselling nonfiction children's book author pairs up with a nationally known writing teacher to discuss revision strategies? Magic.
Sneed B. Collard III and Vicki Spandel blow the roof off everything you thought you knew about teaching nonfiction writing and the purposes for revision. Dozens of strategy lessons pulled from Sneed's professional writing experience followed by Vicki's classroom-savvy tips and exercises give you the nuts and bolts of teaching revision to make nonfiction writing more meaningful, useful, and enjoyable for the reader.
Using a "big-to-small" process of revision, from Big Picture ideas down to individual words, Sneed and Vicki demystify revision and help students become clear, persuasive, compelling-even entertaining-writers. "With your encouragement and guidance," they write, "students will discover the joy of turning their first rough ideas into something readers cannot put down."
