As early as 1742 French naturalist Swiss geologist succession concerning the vegetation development after forest clear-cutting. In 1859 H. C. Cowles [ ] Between 1899-1910, Botanical Gazette in 1899 ("The ecological relations of the vegetation of the sand dunes of Lake Michigan"). Gleason and Clements [ ] From about 1900 to 1960, however, understanding of succession was dominated by the theories of Two quotes illustrate the contrasting views of Clements and Gleason. Clements wrote in 1916: The developmental study of vegetation necessarily rests upon the assumption that the unit or climax formation is an organic entity. As an organism the formation arises, grows, matures, and dies. F...

Plant and animal communities change through time. Walk through the country and you'll see patches of In general, succession forms the most complex Primary succession could happen on a sand dune, a sand beach, the surface of a new lava flow or freshly fallen layer of volcanic ash, or the deposits of silt on the inside of a river bend that is gradually Succession begins with the pioneer stage. It includes a few plant and animal pioneers that are unusually well adapted to otherwise inhospitable conditions that may be caused by rapid water drainage, dry soil, excessive sunlight exposure, wind, or extreme ground and lower The pioneers soon transform conditions, making them favorable for other species that invade the area and displace the pioneers. The new arrivals may be larger plants with foliage that covers the ground more extensively. If this happens, the Sand dune colonization is a good example of primary succession. Animal species also change as succession proceeds. This is especially noticeable in the insects and invertebrates, which go from sand spiders and grasshoppers on the open Secondary succession can occur after a disturbance alters an existing community. Old-field succession, taking place on abandoned farmland, is a good example of secondary succession (Figure 8.24). SUCCESSION, CHANGE, AND EQUILIBRIUM So far, we've been describing successional changes caused by the actions of the plants and animals themselves. One set of inhabitants paves the way for the next. As...

THE NATURAL ENVIRONMENT Geography 101 EROSION Erosion by Wind • Compare wind to other exogenic processes. • In what ways does wind erode the surface and what landforms are created? • How is material transported by wind and what is the relation to grain size? • What are some depositional landforms of wind? • What landforms in Hawai'i have been shaped by wind? BOX 1 Wind can be a persistent erosive force in areas where bare rock and soil are exposed, like deserts and coastlines. Once again, sunlight provides the energy as differential heating and cooling of Earth's surface causes pressure differences that drive the winds. Compared to other exogenic process, like crashing waves or cascading water, wind erosion and deposition, called aeolian processes, are weak, but over time the cumulative effect can produce some distinctive landforms and move huge amounts of material. Erosion In one of the simplest forms of erosion, wind simply blows away loose material, a process called deflation. You can see how the name came about: as loose material is blown away, the land surface gradually lowers, or deflates. Of course, wind cannot carry large particles, so only the finest are lifted into the air and removed. This leaves behind the larger sediments, like gravel and pebbles. Over time this process can produce desert pavement, composed of fields of rocks as shown in the photo. Australia's Great Stony Desert is an example of a large area of desert pavement. Wind can also bounce material al...
