Sheltered Rocky Shore

Extracts from this document...


Sheltered Rocky Shore Rock Pool 1 Rock Pool 2 Abiotic factors * pH value - The pH value of rock pool water sample is 8. - The pH value of sea water is 6.8. ?The pH value of rock pool water sample is higher than that of sea water The possible reason - Excretion of organisms evolved ammonia which is alkali so the pH value increases * Tidal Level - The whole field study was affected by the tidal level - As typhoon Parma is approached, the low tide level was 1.6m at 4p.m. This level was to high to detect organisms which live far away from the coastal area. ...read more.

high temp and low humidity). organism face the challenges of desiccation. ?almost no organism can survive > Rock Pool: When high tide, food (micro organisms) was brought from the sea water. The most abundant of nutrient few varieties of species Organisms need to withstand the fluctuation in temperature and salinity. ?More organism can survive. Error 1. The rainfall in the morning lowered the salinity of the rock pools and seawater. 2. Also, oxygen content and pH value of the rock pools and seawater were affected by the rainfall. -Improvement: Don't record data just after raining. 3. During collecting water samples, the bottles containing air and hence, the value of dissolved oxygen was overvalued. -Improvement: Use a bucket tied with a rope to fill up the bottles until all the air bubbles escape. ?? ?? ?? ?? ...read more.

    Temperature: - A change in temperature does not have an affect on the preferred zone for patella vulgata. It is an inter-tidal species that can tolerate long periods of exposure to air and also variations to temperature. Experiments show that limpets can survive temperatures up to 42�C and 60% water

    To reduce any human error, one researcher will measure the fronds in each quadrat whilst the other records the data. This is so that the method of measuring the fronds is a constant one whereas if two different individuals were to do it the data may be collected differently.

    It is the best size relative to the limpet's size which are small organisms. Also, if it is too small, I would have to move a larger distance to collect limpets which are not in a similar area across the height.

    This happens during the autumn and winter months. They often begin life as males, but like many molluscs, change into females later on at about two to three years of age. Spawning occurs annually and is induced by rough seas and onshore winds, and the eggs are fertilised externally.

    I will also make sure that I wear gloves protecting my hands from catching diseases. There are many diseases linked to unhygienic substances related to animals. Wearing gloves will not only affect my health, but also distort my results; our skins pH level is 5.5.

    We chose a suitable area on the rocky shore where distinguished signs of zonation of organisms could be observed. Then we started our fieldwork by firstly measuring the physical conditions like humidity, temperature and wind speed around the area. Next we laid down a long nylon thread on the rocky to setup a belt transect.

  1. Coastal Ecosystems: Rocky shores

    Exposure extends the marine habitat further up the shore, in a way. This raised the upper limits of organisms. The greatest effect is found on the littoral fringe, which is a narrow band on sheltered shores and much wider on exposed coasts Other modifying factors: * Topography: A shore with

    These buildings attract turtles inland, where can get crushed by people and cars. Solutions, Benefits to Turtles and Examples There are multiple solutions available to each threat presented by humans but with all being directly or indirectly linked to tourism; the resolutions have to be viable and feasible enough for tourist organisations and local governments to accept.
