The articles in this Natural Inquirer include just a few of the renewable natural resources studied by USDA Forest Service scientists. By reading these articles, you will learn about the condition of the resources in the year 2000, and you will learn what might happen to them by the year 2040. In the year 2040, how old will you be? Do you think that the condition of the Nation's renewable natural resources will be important to our society in 2040? Why or why not? The articles in this journal will help you to think about the future of global climate change, the Nation's wildlife, our fresh water, our fish, the trees that grow in our cities and towns, and the conditions that tell us whether our forests and rangelands are healthy. As you read the articles, remember that it is hard to predict the future. Although scientists do the best job they can, many things can change in the future. To find out more about our Nation's resources, read this Natural Inquirer!
This booklet contains several activities that can be used by students to become more aware of how plants, animals, and humans interact within ecosystems, and how one influences the other. The activities can be used singly with other projects, but completion of all activities should give students an understanding of how ecosystems work and how all aspects of an ecosystem are interrelated.
This exercise, which is adaptable for introductory biology students or advanced physiology classes, uses a simple radio telemetry system for measuring body temperature from unrestrained and undisturbed animals. The advantages of this system over traditional probe-type thermometers are enormous. The laboratory will include practice in calibration of the transmitters, instruction in inserting the transmitter into the animals, and experience in interpreting the data obtained.
