<p>All plants need certain resources for survival. And plants differ in their ability to
tolerate various environmental factors. The distribution of plants is largely determined
by their response to environmental conditions.</p>

<p>In the previous activity you discovered that patterns of diversity are associated with
latitude. Some broad patterns of plant distribution are also associated with latitude,
because on a global scale climate varies with latitude. Tropical climates form a warm wide
belt around the equator. Climates become increasingly frigid toward the poles. At the same
latitude, however, climate conditions are variable due to regional factors.</p>
<p>Below are climate data for two cities in Oregon, Portland and Bend. Notice the
average temperature is given in degrees Celsius, rainfall in millimeters. Why?</p>

<p>Biome: _____________________ Biome: _____________________
<p>Check your predictions against a biome map. How did you do?</p>
<p>It takes about 3.5 hours to drive from Portland to Bend, located in central Oregon.
What regional factors make the climates of these relatively nearby cities different?</p>
<p>List at least 2 plant species that are characteristic of the biome in each region
and adaptations of these plants to their environment.</p>
<p><b>Think about biomes a bit more...</b></p>
<p>Arctic tundra covers about 19% of North America. How do plants survive at such low
temperatures and with such short growing seasons? Plants in alpine regions also face
environmentally harsh conditions. How are conditions at high latitudes and high
elevations similar?</p>
<p>There are three major desert formations in North America: the Mojave Desert, the
Sonoran Desert, and the Chihuahuan Desert. Desert scrub also extends through the Great
Basin region. Map the 3 major deserts and identify some plants common to each desert.
Do the plants show similar adaptations to desert conditions? How do the deserts differ?
Compare, for example, their rainfall patterns.</p>
<p>Grasslands of central North America are often called prairies. Do tallgrass and
shortgrass prairies differ in ways other than height?</p>
<p>How does the temperate rainforest in the Pacific Northwest differ from a tropical
rainforest? In what other parts of the world are temperate rainforests found?</p>
