One of the assignments throughout the length of the class were draft submissions. For this assignment we had to submit about 6 draft entries every week, which equated to about three hours of writing. When I first heard about this assignment I was not looking forward to it. I was worried that I was not going to have a lot to write about because Writing in Biology is the only writing based class I am taking this semester. Every week as I worked on the drafts I realized that finding things to write about was a lot easier than I thought. The draft entries were not graded for the quality of the writing, so it made it much easier to work on writing. This assignment forced me to write more throughout the week in shorter blocks of time rather than try to squeeze all of my writing right before the due date. I will use this technique in my future writing because I feel like it really benefited me and my writing by limiting procrastination. 

We chose to test the colors white versus yellow and cyan versus green in our experiment. Some species of crab spiders are able to change their color from white to yellow, and yellow to white. We decided to use white and yellow as a control in our experiment and see which side the spiders would prefer. The color white is made up of red, green and blue all at their highest intensities which is 255 in the RGB color model. Yellow is made up of red and green both at their highest intensities of 255, with no blue is added. The next set-up contained cyan and green. Cyan is made up of green and blue both at their highest intensities of 255, and no addition of red. Green is made up of only green at its highest intensity of 255.

To collect data we took measurements once a day for eight days in a row. Everyday we collected two measurements. The first measurement was what color side the spider was on when we first entered the room and before interacting with the spider. The second measurement was taken after moving the spider to the middle of the tank where the colors met. We gave the spiders a ten minute rest period before taking and recording the data on which color side background the spider chose.

We used two spiders in our experiment, and each was given its own tank. One spider was placed in yellow versus white tank, and the other in cyan versus green tank. The color backgrounds in the tanks were split right down the middle and the other factors including light entering, materials and temperature were kept constant between and within the tanks.

Ulva lactuca is an early colonist who has an effect on the later arriving Gigartina conaliculata. Figure 1 shows us that it is a facilitation relationship. Facilitation as a successional mechanism says that the early arriving species will make it less suitable for other early arrival species, but more suitable for late arriving species. This is seen in Figure 1 because when Ulva is present the number of Gigartina is much higher than it is when Ulva is removed.

Question 2, Part A:

Figure 3 shows the effect of thinning Aspen in its early successional stage. Before the thinning of the aspen the morality percent of aspen and fir were both about 5%. After the thinning of the aspen the morality of aspen increased slightly to about 6%. This is not the same for the fir, which instead jumped up to almost 21%. We know the aspen is the early arriving species, and without it fir do worse. This shows a facilitation relationship between the two species
