More Scat!


video
In the last scat video, we worked in a small area of 10m x 10m. After we finished one small area, we would move to the next small area and do the same process again. In this video, we walked a mile down a transect and looked for many different types of scat. We found coyote, deer, hare, porcupine, and raccoon. We also looked for other evidence of mammals such as burrows, food stores, trees being chewed by porcupines and tracks. Why do you think we are using two different methods to find mammals? What does each method tell a scientist?

  1. I think you are using two different methods so you can find out a lot of different information. So, if you only looked at porcupine trails and not the scat, you might no know anything else about the porcupine.
    One method (Tracks, chewed trees, etc.) could show where the organism went and what it does, and the other method (scat, etc.) can tell you what the organism has been eating. We miss you Ms.Davis! Have fun!

  2. Using two different methods can maybe have a good amount of information, to determine a population size.
    I think looking for burrows or food stores might have some evidence that could of told if the animal is still living there, or if it was, but it died.
    Once again, that could help determine a population size.
    Miss You!

  3. I think you used two methods to get a more accurate result. Also because the scat and everything could be scattered not just in one area they will be scattered everywhere.

  4. Hey Ms.Davis!

    I think that you are looking for multiple signs of animal life because you want to make sure that you have sufficient evidence of animals. I think that the scat evidence shows a scientist how many animals have been there and other evidence shows them those animal's habits.

  5. Hi Ms.Davis!
    I think you used the different methods for more info about the mammals and also if one method didn't work you still could have a lot of information. Scat can help you figure out how many organisms there are and what their appetite is. The other method helps you determine how the mammals do and where they live or burrow.

  6. Ms. Davis,
    I think you are using two different methods because then you can compare your results and maybe see which one works better. Well the first method (the one where your working in small areas) tells you about how many animals there are there and how healthy they are and what kind of food they are eating. The other might tell you a lot about the prey of the animal, and how big the prey's population is.

    PS Our watershed experiment went wonderfully today in science class!

  7. I think you are using tow methods to get better data. If you find four different tracks from a hare but only two pieces of scat you might be able to calculate the population.
    See you tomorrow (via skype)

  8. I think that the reason you are using two different methods is so that you can be sure that you are accurate. The first method is to estimate how many animals are in the area, but you can't be exact with it because the scat could be from the same mammal if you are in the same area. The second method works to double check what you have and see how many different burrows or other things there are.

  9. Hey Ms. Davis,
    I think that you used two methods of finding evidence because if you found chewed up tree, food stores, or burrows that tells you that animals live and eat in that area. But if you just look at scat, it will only tell you if an animal has been there. Any animal could be walking around aimlessly and just decided to poop there. Scat could also determine how long an animal travels after eating. Say a deer eats a kind of grass, but you find there scat four miles away from where the grass grows.

    We miss you so much

  10. I think you would use two methods of tracking animals so you can have a better chance of getting information. The information would also be more accurate. It would also be good to use 2 methods if when doesn't work then you still have a back up. The first method might be used to determine the health of the species as well as the population size. The second method might tell you more about how the species are evolving and if they have enough resources to build their homes and live. This method would also help you determine the population size.
