* 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.

    It has to contain a substantial amount of different species in both areas of trampled and non-trampled land, to enable me to compare them. The areas have to be maintained by the people who visit the park, the non-trampled area has not been interfered with by the park rangers and the trampled area is not artificially trampled (i.e.


    to refer to the processes that maintain a constant internal environment. 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

    EXPERIMENTAL DESIGN APPARATUS: ? 15-25 Bluebottle blowfly larvae ? 60 Watt lamp ? Petri dish ? Pencil ? Stopwatch ? Ruler ? Compass ? Protractor ? Scissors ? A2 Sheets of paper Note: Only use Calliphora larvae that are ready to pupate within a few days because this is the period in which they are most sensitive to light.

    Ultimate causes are environmental threats that caused the endangerment in the first place. They are explanations that address the historical and evolutionary reasons why organisms respond as they do to their immediate environment. Examples are DDT (and other pesticides), habitat loss, and the introduction of an exotic species.

  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. An Investigation into the water quality of the River Banwell in

    Ammonia national average was set at .569mg N/l and the river Banwell was measured at .629 again above average but was issued a C. The final test was for dissolved oxygen, which received a D grade as it was tested and had a low oxygen saturation level.

    The aspect will also play a part in the species abundance and the species diversity. In Britain a southern aspect will receive more light as it is facing the equator which is facing the sun. This means that a southern aspect will have a higher abundance because there is more light available.

    In order for the plants in this area to survive, they need to have special adaptations. The forest floor is the lowest layer of the woodland. It is mainly composed of humus, litter, topsoil, branches and dead leaves. This makes this layer suitable for woodlice and earthworms to live in.
