An investigation in the different species of plant life through bare sand and grassland and what factors effects the growth of them.

Extracts from this document...

Introduction

An investigation in the different species of plant life through bare sand and grassland and what factors effects the growth of them. General site description Geographical location - Sheet NU04 045470 Altitude - West, I started going up the dune 2m at a time and gradually went over and went up the next dune. Aspect - I looked at the dunes on both sides and up the next one investigating the different types of plant life and on what part of the sand dune they occur. Topographical - I started off at the point that I assumed the full tide will be up to (I assumed this by looking at where the wet sand ended). I climbed the sand dune every 2m and took measurements at each base. As I went over the dune I looked at the different species of plants that occurred. Introduction The overall aim of this investigation is to investigate the different species of plants in a stretch of land stretching from where the sea comes up to on the beach then over the first dune and up to the peak of the second dune in from the sea. On the way I will have to investigate the area the different species thrive in to be able to conclude what factors affect the growth of them and prove that marram grass only grows on certain parts of the sand dunes and if it has a factor of keeping the embryo dune together.From doing past work in biology I have learned that marram grass is a xerophyte so this plant is basically keeping the dunes together but I will have to investigate if the levels are changing as I go over the dune or if its stays at a constant level. Throughout this investigation I will have to keep a fair test to make the results as accurate as possible. ...read more.

Conclusion

There was one problem that I thought I had with the equipment and that was that I was using a pond thermometer for recording the temperature readings which I thought was not very suitable for reading the soil temperature as I would or liked it to have a more direct contact with the sand. So this could be said to be a limitation of this experiment so I would change this if I were to do it again. There were limitations to my experiment for example when I was recording the % coverage of each plant the values were definitely not accurate due to that I was just estimating the % of each plant that was growing there just by looking at it. I found when doing the profile of the dune it was quite accurate even though it wasn't accurate to the last mm I was able to look at the sand dunes pretty accurately and it showed a good profile of the embryo dune and mobile dune that I was able to use in my analysis. My statistical test was not proven to be correct, as it was not close to1 because this would mean that there was correlation present but this was down to taking the % coverage by estimate which is not that accurate. If I were to carry out this experiment again I would of done more belt transactions of the sand dune so it could compare them as well as going over the mobile sand dune to see if this also agreed to my predictions. Another thing that I would of also did was to use more quadrants at each station so I could get a average of plant species in that area which I would think would make it more accurate due to not all of the area at each station was exactly the same so a average would be better. So to conclude from to this investigation I can say that the marram grass plays a big part of the formation of the embryo dune so other species are able to be introduced further on. ...read more.

    Research question - Is using dogs for work ethical?

    5 star(s)

    I believe that some dogs are born into 'a human family', they grow up surrounded by humans and therefore they adopt a part of the human lifestyle and behaviour. I believe that dogs can also be habituated. The definition of habituation is where an animal no longer reacts to a stimulus that made a reaction to begin with.

    I will then set up the equipment in the non-trampled area and repeat the measurements of species diversity and soil depth. After collecting all the data that I need I have chosen to carry out a Mann Whitney U statistical test.

    As my result (10.96925) is above this number, then the probability that my results occurred due to chance factors is very slim indeed. This would mean that my null hypothesis: - "Woodlice do not have a preferred environment for living in.

    Therefore, the milks I have chosen to use are: Full fat pasteurized, Semi-skimmed pasteurized, Ultra High Temperature (UHT), and Raw. To ensure the most accurate results, it is important to use sensitive equipment. However, as the results of the pilot study later show, the more sensitive the equipment, the more likely human error can influence the results.
