General Comments:
The water that was observed were randomly taken from a pond water. Our group was able to locate four different species of Protists. The diversity of Protists were evident from the four species that we spotted from pond water sample. Some were round like Green Algae and others were long and segmented like Mosquito Larva. In addition, when observing these Protists under microscope, some were slow moving and others had fast movement. For example, Euplates was the one that had fast movement.
After looking through my own group and other group’s blogs and findings, I noticed how there are plenty of different organisms in the same group out there. I didn’t get to performed this lab and thus did not see how each of these organisms moved, but I am sure they differ. However, I noticed that they vary in color and size as well. I got to differentiate one type of organism by looking at their characteristics and pictures that were provided in lab but it would have been better and easier if I saw it in person but great job!

ReplyDeleteI found the mosquito larva specimen the most interesting maybe because to me it is the grossest (not sure if this is a real word). After further research you can tell Aedes, Anopheles and Culex larvae. An indication of the genera of mosquito larvae can be made from the length of the siphon. Anopheles have very short siphons while Culex tend to have the longest siphons.I also learned that Both Aedes and Culex larvae hang down from the water surface at an angle. An adult female Aedes aegypti, commonly known as the 'Dengue' or 'Yellow Fever' mosquito.Also, alot of the species on this page are the major verto for Dengue. Who knew those pesky mosquitoes could be so interesting?
ReplyDeleteAfter looking at my group's pond water sample and comparing with your group's sample, I can see that there are many different types of organisms living in the pond water. Especially, I've never seen a mosquito larva this close up, so I found it is very interesting to look at. Also, whenever I look at the picture of your mosquito larva, it reminds me of a skinny caterpillar. Thank you for sharing these pictures.

ReplyDeleteHi guys,
ReplyDeleteAfter comparing your results to my group's observations, it really is amazing how many different species of organisms live within the same source. My group also saw green algae, but it was interesting to see the dinoflagellates, euplotes, and especially the mosquito larva. I wish you guys had videos of the movements of the different types of protists, but the pictures all looked great too. Great post you guys!
The pond water is actually so diverse. We had a type of green algae as well, however that was the only similarity noticed between our 2 posts. The mosquito larva you guys spotted is really interesting. Did it move fast through the water?
ReplyDeleteA mosquito larvae? AWESOME. Thanks so much for sharing. One question: what do you estimate the length of the larvae to be, and could you guess the age of the larvae based on that?
ReplyDeleteThe mosquito larvae reminded me once more of the great diversity in niches that we simply cannot see with our eyes. In our water, we found algae and protists, two broad categories of organisms from two different kingdoms. The mosquito represents yet another kingdom: animalia.
There is such diversity, seen and unseen.

There are some natural remedies that can be used in the prevention and eliminate diabetes totally. However, the single most important aspect of a diabetes control plan is adopting a wholesome life style Inner Peace, Nutritious and Healthy Diet, and Regular Physical Exercise.
