Introduction

* A plan to investigate the abundance of Species in the John Ruskin Woodlands in relation to Light intensity as an abiotic factor. The aim of this investigation is to is to determine weather the abundance of species vary across the John Ruskin Woodland, which was observed by a naturalist. In order to investigate this finding, a scale map of the John Ruskin Woodland must be constructed. This provides the basis of were the belt transacts will run. It will also give an idea of the changes in the environmental gradient. The transact recording method will be used in order to determine the abundance of species across the woodland. Due to time limitations, the belt transact will be interrupted. After intervals of every 2 meters, a reading will take place of the species present within the quadrat. ...read more.

The bottle will have to be labelled according to which belt transact the sample was along and the quadrat frame the soil was in. In order to keep the value of the pH constant, it is the location of the belt transact will have to be away from areas which have heavy human impact, i.e. the presence of public bin's and footpaths. This can alter the pH of the soil, as the substances released can be either acidic or alkaline. In the laboratory, 5cm3 of distilled water will be added to the 1cm3 in the sterilised bottle. After shaking the bottle rigorously, 3 drops of universal indicator solution will be added to the soil solution. The colour change of the solution will indicate the pH of the soil within the quadrat. The temperature will also have to be considered as it can vary slightly across the environmental gradient. ...read more.

    An experiment to investigate the species diversity in non-trampled and trampled areas.

    4 star(s)

    They are found mainly in areas of low light intensity and dampness, commonly in wooded areas and the edges of streams. Moss growth can be inhibited by a number of methods: increasing direct sunlight, raising the soil pH, increasing number and resources available for competitive plants like grasses and decreasing the water availability.

Factors that must be kept constant include chemical constituents, osmotic pressure, carbon dioxide and temperature, the latter being the main feature of this discussion. Many physiological processes are homeostatic in that they are directly or indirectly responsible for regulating

    This increases plant output. When these are released eutrophication occurs (see description above). Phosphate cycle A source of phosphorus is vital for all organisms. It is needed to manufacture DNA, ATP and protein. Therefore the more phosphate there is the more productivity occurs.

  1. An investigation into whether varying light intensity at a stream affects the species diversity

    The necessary energy comes from absorbed light energy.iv There are two sets of reactions involved: the light-dependent reactions in the chloroplast lamellae and the light-independent reactions in the chloroplast stroma. During photolysis in the light dependent stage of photosynthesis, water is broken down by light: H2O --> 1/2O2 + 2H+

  2. What sorts of species become 'invasive aliens' in a world of climatic change?

    The economic impact of invasive species can be significant, for example, the estimated cost to the United States economy in 2001 was $125 billion (Baker, 2001). Research into ecosystems containing alien species was often explicitly avoided in the past, as they were perceived as 'unnatural' and therefore unable to provide insight into 'real' ecological processes.

  1. To see how Blowfly larvae (Calliphora) react to light.

    a region of the paper circle where the intensity of the light is not as strong, generally moving into the negative region, with a few in the neutral zones. The reason for this is that the larvae needs to avoid the possibility of becoming prey to a predator, just before it is due to go into the pupal state.

    This transition stage has occurred as a rocky shore. A rocky shore is divided into three main zones, supra littoral, littoral zone which is divided up into a further three zones upper middle and lower littoral and sub littoral. Within each of these areas zonation occurs vertically upon the strata as well as horizontally.
