It is a free upgrade. Most rivers in the United States are now regulated. A regulated river is one whose flow is controlled by dams. The regulation of rivers, however, alters the relationship between rivers and their floodplains.The scientists in this study were interested in studying how toads reproduce in the floodplains along the Rio Grande.

"Science Topics" covered in this article:
"Thinking About Science Themes" covered in this article: Taking measurements is a common practice in everyday life. Most scientific experiments involve units of measurement. Units of measurement are things like inches or centimeters, miles or kilometers per hour, ounces or grams, or frequency. A scientist may want to know, for example, how many times a Screech owl visits a particular Red Oak tree during the summer. In that case, the unit of measurement is frequency. Think of three things you have measured today. As you read the “Introduction” section of the article, make a guess as to what the scientist will measure in the research. Identify what unit of measurement was used. Specific "Thinking About Science" Themes:"Thinking About Environmental Themes" covered in this article: Think about what it takes for you to survive everyday. Aside from food and water, humans need clothing and shelter. If adults are raising a family, they must provide for their families as well. Animals must also have certain things to survive. They need a place to live, things to eat, and a place to reproduce. The environment in which a species lives is called its habitat. In the study you are about to read, scientists wanted to learn about the best habitat for toads to reproduce. While reading the article, identify how humans impact the habitat of toads. Remember that humans have both positive and negative effects on an animal’s habitat. Specific "Thinking About the Environment" Themes:NSE Standards covered in this article:
