Microclimates and vegetation

Dan Kay 316 Rust 800

Climate on the broad scale, across hundreds of kilometers, brings about the broad-scalc distribution of vegetation types (Chapters 1 and 2). However, even looking at the world much more locally, wc see that there arc also very substantial differences in the average climatc. For example, a south-facing slope has a different climate from a north-facing one. The year-round temperature and rainfall conditions under a tree will be different from those just a few meters away in the open. The...

The Worlds Major Vegetation Types

Coniferous Forests Iran

In the broadest sense the world's vegetation can be divided into several basic structural types, each of which includes several bionics 1. There is a set of forest vegetation bionics, which have a dense, closed canopy of trees. If you stand and look upwards in a forest, you see few large gaps between the crowns of the trees, which tend to overlap and interlock with one another. Forest biomes include tropical rainforest, temperate evergreen forest, temperate deciduous forest, and cold climate...

Box 81 Q C3 and CAM plants

Many plants in arid environments decrease the problem of water loss through stomata by chemical tricks that help them take up CO with less water loss. These are known as C4 and CAM plants. Most plants are known as C3 plants. They take CO up into leaf cells which handle the whole photosynthetic reaction in the same cells. The C02 gets fixed into a three-carbon chain (hence the name C3), and then in the same cell the water-splitting part of photosynthesis gives the hydrogen needed to tack on to...
