Why is water scarce in parts of the world and who is most affected? Usually the temporal dynamics of predators, prey, and herbivores are resolved over similar spans of time, so at least conceptually, measurement of food web dynamical properties can be done at the same scale. She has a Bachelor of Science in biology and Master of Arts in English and has worked many years as an educator and as a writer and editor for academic, science and environmental publications. Population Education provides K-12 teachers with innovative, hands-on lesson plans and professional development to teach about human population growth and its effects on the environment and human well-being. For example, continuity has been studied for 25 years (and much earlier with Clement's (1916) consideration of organic residuals. ). Robert Brandon (1996) has developed a classification of studies in evolutionary biology that can also be applied to experiments in ecology. Population Themed Science Fair Projects: The experimenter still manipulates the independent variable, but in a real-life setting (so cannot really control extraneous variables).
