Your introduction was good and you collected a lot of data, but it was confusing to read. First, in the methods, you need to indicate what concentration of RA acid you used, and say which days you changed the solution and fed the fish. Most of what you have in the conclusions should go in the results section, and there it should be organized by day of observation. In one paragraph you used Day 3 on 2/26, but I think you called this Day 7 when you were talking about measuring the preserved fish. It is also unclear how many fish you examined for the characteristics you describe. For example, if you measured the length of 3 fish, you should calculate the mean and standard deviation and state that n=3. If you only measured one, you should state that. LS

3/6/2015 This was good, but it would be nice to say which sample you sequenced from your original table. Did you also find it to be gram negative? Was it from a tet or non-tet plate? Also, what happened with your other sequence? LS

Vert lab - I like that you specified which animals you observed and which you did not , and the evidence that you used for those you did not directly observe. It would be good to include more detail about when you observed animals - time of day, temperature. Don't forget to add the hawk in your food web.

Invert lab - very good. I'm pretty sure nematodes can find food though - even though their movements appear random, they have chemosensory organs and a simple nervous system! LS

2/12/2015 This is good, but a few things to change if you use the data in your lab report. Although there was not a place for it in the table, the lab manual did ask you to identify the genus of your five plants. For the lab report, you could add a column to the table. Also, you should estimate the height of the whole plant rather than the specimen you brought back. Finally, there was only one fungus in the dish - it's common name is black bread mold, and scientific name is Rhizopus stolonifer. It is in the class of fungi called Zygomycetes. LS

2/6/2015 Very good! I liked that you included descriptions with all of your photos. You probably did not have Archaea on your tet plates, either, because they probably do not live in your transect. LS

1/30/2015 Your drawings of the protists are nice! The introduction is missing a hypothesis/prediction. You kind of have this in your data section when you talk about organisms being closer to vegetation, so you might just want to move those two sentences. The conclusion should also talk about whether you did find a difference between the two niches. You should have tried to measure the lengths of the protists using the ocular ruler. For your serial dilution, it is 10 mL of nutrient broth, not 100. Also, I can't see the image for the dilution. LS

1/26/2015 You did a very thorough job describing your transect. Please add a little about how you made the Hay Infusion. The links to your figures do not appear to work - maybe you didn't save the uploaded images? Remember that "abiotic" does not necessarily mean man-made; it includes water and soil. LS
