WORLD VEGETATION PATTERNS: Calculating the ratio of the visible and near-infrared light reflected back up to the sensor yields a number from minus one (-1) to plus one (+1). The result of this calculation is called the Normalized Difference Vegetation Index, or NDVI. An NDVI value of zero means no green vegetation and close to +1 (0.8 - 0.9) indicates the highest possible density of green leaves. Coverage of this dataset spans January 1982 to December 1998.

Managing the Environment Biomes The human mind seems to require that we group things into categories. Many of the things we group into categories are continuous, not discrete, such as color, temperature, moisture levels. Communities of species are the same way. Sometimes we can see discrete boundaries on the landscape, such as the edge of a lake where it meets the shore. More often than not, however, changes are gradual. So, when we talk about biomes, keep in mind that they are a human construction to help us understand the distribution of organisms on the face of the earth, but not actually "real." Also, each investigator has a slightly different way of naming and categorizing biomes. If you look at five different books that describe biomes, you will see five different treatments. The important thing is to understand the variation and be able to describe the major features of each type. An excellent Web Site with vegetation and plant distribution maps is: http://www-sul.stanford.edu/depts/branner/vegmaps.htm

Extractions: On this page you'll find links to my lecture notes, study guide sections, and WWW resources relevant to each of the major topics in the course. Lecture notes are two formats. Word Perfect 6/7/8 files (those with the .wpd extension) can be downloaded and should be readable in a number of different word processors, but the formatting (especially of the graphics) may get wonky. Adobe Acrobat files (those with .pdf extensions) can be read on-line and will print out just the way they look (in theory, at least!). You'll need the Acrobat Reader to do this; all computer labs on campus have it installed, and you can download it for free from Adobe. I'm still working to develop more WWW links, so if you have any brilliant ideas, let me know

Extractions: e-mail Kevin C. Hartzog Fossil Project Click here for a printable version Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (Campbell). The importance of biomes cannot be underestimated. Biomes have changed and moved many times during the history of life on Earth. More recently, human activities have drastically altered these communities. Increasing human activity over the past several decades has rapidly altered or destroyed many ecological habitats, thereby changing the biomes. Biomes are classified in various ways. One can group biomes into five major types: aquatic, deserts, forests, grasslands, and tundra. Biomes may be broken down into smaller groups. The forest biomes can be further divided into tropical and temperate forest, or rain forest coniferous forest, and deciduous forest. The grasslands can be divided into the savannah and temperate grasslands. Tundras can be broken into arctic and alpine tundras.
