The purpose and methods were very well-written, but you need to include the concentration of ehisterone used and the stage(s) of the embryos when you started. On day 4, had all of the embryos hatched? When you say that no developmental differences were observed on day 7, you need to list what you actually looked for - size, motility, etc. You are lacking quantitative data - did you measure the length of the preserved fish and diameter of eyes? If so, you should give those measurements and say how many fish were measured. If it was just one fish, you can say it was a representative sample; if multiple you should calculated the mean and standard deviation. It is good that you have pictures of your specimens. This is a good start, you just need more descriptive data in the results section.

3/6/2015 The entry started out well, but you need to provide more information about the identified bacteria and compare it to the observations you made back in lab 3. Was it from a tet-plate, and is it known to be antibiotic-resistant? Is it gram + or -, and does the cell and colony morphology that is described in the literature match with what you found? LS

Vert lab - I'm glad you included all of the organisms that we've studied in your food web. Remember, though, that bacteria are not protists (Paramecium, etc). Some of your protists may eat bacteria or they may eat plants, so you should look that up for your particular species. While it is possible that humans would accidentally eat the bacteria in your transect, they probably don't consciously eat anything, so I don't know if I would include them in the food web. Dogs might be just as likely to eat the birds or squirrels as the insects.

Invert lab - Great job on your transect data. You didn't talk about how the worms' movements related to their body cavities, though. LS

2/15/2015 Nice job, you're just missing the photos/drawings. Also you should have discussed the thought questions about fungi using one of the examples we had on view in the lab. Your tree is a dicot. For your lab report, you should try to identify the genus of plants. Your bush is a rose bush, and for the grasses/weeds you can try http://www.ipm.ucdavis.edu/TOOLS/TURF/TURFSPECIES/index.html or http://www.usna.usda.gov/Education/Science.pdf LS

2/6/2015 This is very good. Next week, make sure you include photos or drawings of your plants! LS

1/30/2015 Great job! In the future, use either your own photos or drawings (as you did for the unidentified protist) rather than the pictures from the key. LS

1/26/2015 This is a good start. Under Purpose, you could eliminate or remove the sentences from "These observations...a wall." These are covered in the methods and data sections. I would add a sentence about the overall objective of the transect labs relating to ecosystems (see p. 11 and p. 16 in your lab manual). And don't forget to add your map! LS
