Distribution of Species in a field

Extracts from this document...

Introduction

The Distribution of Daisies in the School Field The results of our research showed that the most daisies (common Bellis Perennis) grew in the middle-trampled area (48 daisy average), as opposed to our (my group's) original predictions that they would grow in the least trampled area (36.8 daisy average). We were however correct when we predicted that there would be least daisies in the most trampled area (0.4 daisy average). I have concluded that there were most daisies in the area in which there had been a medium level of trampling because of three main reasons. ...read more.

Middle

than the daisies in the least trampled area (65mm average); this is because they are less likely to be caught on shoes and they are stronger as they are less flexible. Secondly, the trampling of the ground churns it up and this causes it to be more aerated. This means that there are more air pockets inside the soil, making it easier for the plant to grow. Lastly, the trampling spreads the pollen from the daisies throughout the area so that it pollinates surrounding plants and subsequently the seeds are dispersed from the flowers. These are trampled into the ground and, providing that they are not destroyed, will grow. ...read more.

Conclusion

In the most trampled area, the daisies simply did not have enough time to grow and were destroyed by the large amount of trampling before they had a chance to become large enough to withstand the threat of the trampling. Even so, the large amount of trampling would likely overcome the defences of the daisies even if they had time to adapt. In conclusion, because the test was random it was perhaps more accurate and less biased than if we had chosen the exact places to place the quadrats, however there was still a certain amount of chance involved. The only way to overcome this would be to do this test many more times until the results in each individual area were reliable, although this could almost never be fully accurate. ...read more.

    Smreciu and Currah (1989) also found that though 15 species of North American and European orchids responded to different fungi, several fungal isolates induced germination in more than one species of orchid. They also showed that Ceratobasidium cereale Murray and Burpee could become pathogenic on North American species.2 Though germination

Thus in 1973, 1.532 billion new and refilled prescriptions were dispensed from community pharmacies.

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

    In reality, the boundary between invasive and non-invasive is a somewhat arbitrary, though conceptually useful, break imposed upon a spectrum of species success. Invasiveness has also been conflated with the ecological or economic impact of a species (for example, see Biotech Resources, 1995-1998 and IUCN, 1999), although this interpretation is not necessarily helpful (Richardson et al., 2000).
