> > __** What we are going to do: **__ > We are going to do a horizontal transect of the field site. We will be sampling the grass sites and bush sites. We will take 3 samples in the bushes and 3 samples in the grass. This ensures that we have repeats at each site. To ensure that the populations are independent our sites will be a certain distance apart (20-30m), which could be measured by a preliminary survey of the site.This will confirm that there is minimal gene flow between the different populations. We will have standards within the group, which will be set before the task - to clarify the colouring and banding of the snails. We will also be taking our samples at the same elevation to eliminate one variable. ______________________________________________________________________________________________________________________

Revised Plans > Alaina Morgan > == == > __**What we are going to**__ **do:** > We are going to do a horizontal transect of the field site. We will be sampling the grass sites and bush sites. We will take 3 samples in the bushes and 3 samples in the grass. This ensures that we have repeats at each site. To ensure that the populations are independent our sites will be more than 20m apart. We will have standards within the group, which will be set before the task - to clarify the colouring and banding of the snails. We will also be taking our samples at the same elevation to eliminate one variable. > > __**Weaknesses.**__ > The weaknesses of our study are that we are not including the forest habitat in our samples. However, we only had 6 samples and we wanted to measure only 2 sites to allow us to do repeat samples. Another weakness is only having 6 samples as this is a small sample size. To overcome this, we could compare results with another group. > > **__Strengths:__** > A strength of our study is that we have controlled as many variables as we can, which means controlling the altitude of the sampling site. Also, our samples will all be independent of each other because they are more than 20m away. > > __**Drift VS Selection:**__ > If selection is causing the distribution of the variations in the snail population then the same colour/bands of snails will be found in the same habitat across the field site. However, if it is caused by drift, then different sites will be independent of each other and the distribution could be more random, meaning that the same type of habitat might have different coloured snails.
