The effects of soil formation and nutrient availability on community composition
|
|---|
| Description |
Elucidating the factors that determine community composition is one of the important questions in present ecological pursuits because of its impact on ecosystem stability and functioning. Here we propose that soil formation, which determines nutrient availability, has an impact on patterns of community composition. Central-coastal California is an ideal location for studying such processes because of its hilly topography; distinct communities exist in different regions of these hills depending on slope and aspect. I hypothesize, based upon differences in soil development, erosion, and soil depth, that these communities are partly structured by their soil environment. These soils likely differ in relative nitrogen, phosphorus and sulfur availability and these levels may have a strong influence on the species composition of communities. Nitrogen, phosphorus and sulfur availability in the soil and dominant vegetation will be measured at each of the different communities to determine if the differences in nutrient availability are linked with differences in nutrient levels within the dominant plants. A factorial fertilization experiment will also be constructed to determine if different nutrients limit plant productivity among the slope positions. The results will help to clarify if soil development and nutrient availability does, in fact, have an impact on community composition.
