Cooks Lake




Today we set traps at Cooks Lake, which is a very different habitat than East Port. There are mice, voles, meadow and woodland jumping mice, as well as bog lemming at this site. This area looks more open and less dense than East Port. Using our mark and recapture method, we tallied up our total number of Mice and Voles at East Port to be about 22 per hectare (100m x 100m).
In Cooks Lake, we also put traps in two different areas: meadow and woodland. Where do you think we will catch the most mammals in the meadow or wooded sections of Cooks Lake and also how many organisms do you think we will find at this site? Sorry the pictures posted out of order. The first picture is of the woodland site at Cooks Lake. The second is of the East Port Site. The third is of the meadow site at Cooks Lake and the last is another of the East Port site. Look online to see what habitats mice, voles, and lemmings might prefer.

  1. I think that you will catch the most mammals in the meadow of Cooks Lake. I think this since these animals like to burrow and hunt for food in meadows. I think that you will find more animals than at East Port because East Port has more trees than the meadow in Cooks Lake.

  2. I think at the meadow because the meadow will provide food and shelter.

    However, the woods can also provide food and a place to hide from other animals.

  3. I think you will catch the most mammals in the wooded sections of Cooks Lake because the animals would probably do more exploring there, and because more mice, and voles would be there, but I believe that there will be about the same number of lemmings in the meadow as in the wooded section.

  4. Hey Ms.Davis!!

    I think that you are going to catch more mice and vole in the woodland because there is more cover there and the mice and vole wouldn't have to worry as much about cover as they would in a meadow.

    Stay Warm!!!

  5. I looked online and it said that voles prefer open grassy areas so I think you might find the most voles in the meadow at cooks lake.

  6. I think that you would probably find the most animals in the forest because it seems like a good place to hide and has lots of resources. Mice and vole both like to chew on things to wear down their teeth so the forest sounds like a good place because there would be a lot of wood to chew on.

  7. HI MS DAVIS!!!!!

    I think you will find more mammals in the forest because it provides food/shelter/protection for their prey, or themselves.

    Maybe the mice and voles will like the forest more because it provides more shelter, and cover from predators. Also, the forest has more trees that might contain seeds/acorns that fall on the ground, so it will provide more food. Then again, in the meadow there is grass, bushes, and berries that provide more food, and still some shelter, so it depends on what they prefer.

    MISS YOU!!!

  8. Hi Ms.Davis, I think the rodents like both places.. woodland because its more protective but meadow because they like to hunt there

  9. I think that the voles will live in the meadow because it seems like a good place to find food and water and also a good place to dig burrows. I think the same with mice. I searched what a good place for a lemming is and it said forests/woods. I think this because it has a lot of shelter and good source of food and water.
    MISS YOU AND STAY WARM!!!!!!!!!!!

  10. I think woodland because there is more protection. Also, I saw that voles eat mainly grass and plants and in the picture you posted, it looked like the woodland has many plants and grass for the voles to eat. I think that would be where you find most of them.

  11. Hi Ms. Davis!!!
    I think that you will catch more mice and voles in the woodland. I think this because according to the pictures it looks like the woods have more places to hide in, so more animals will feel comfortable there.

  12. Hi Ms. Davis,

    I think there will be about an equal number of organisms in the meadow and woodland. Both look like they have lots of places where small mammals (like voles, lemmings, and mice) can hide or camouflage. According to http://www.bio.davidson.edu/people/vecase/behavior/Spring2007/Martens/habitat.html, lemmings depend on hiding to survive, so there will probably be many lemmings at Cooks Lake. The website http://people.westminstercollege.edu/faculty/tharrison/gslplaya99/voles.htm said that voles lived in meadows in Canada, so there actually might be more voles in the meadow. http://www.psu.edu/dept/nkbiology/naturetrail/speciespages/woodlandjmouse.htm said woodland jumping mice like cool, moist forest floors, so they probably like the woodland (and they are named WOODLAND jumping mice).

    I think there will be an about equal number of lemmings in the woodland and meadow, more woodland jumping mice in the woodland, and more voles in the meadow. I think the population density of mice and vole will be approximately 14 per hectare because Cooks lake is less dense and more open than East Port, which had a population density of 22 per hectare.

  13. Hey ms. Davis!
    I hypothesize that you will find more voles in the meadow at cooks lake because there are more plants for it to feed on, and since voles are near the bottom of the food chain it probably eats plants, and maybe insects that are smaller then them. It seems like a meadow would be a safer, and better place for a vole to live.

  14. Hi Ms. Davis,

    Both the meadow and the woodland have a lot of places for small mammals like lemmings or voles to camouflage/hide. I looked online and it said that lemmings depend on hiding to survive, so I think you will see lots of lemmings (if they're not hidden too well) because they would probably like living in a place with many hiding places. The woodland jumping mice will probably live in the woodland because that might be why they are called woodland jumping mice. I think there will be more voles in the meadow because it said online that voles preferred meadows. I hypothesize that you will find fewer animals here than East Port because you said it looks less dense. Maybe there will be around 15 per hectare here because I think the population density here more sparse.

  15. I think that you might find more small mammals (Mice lemmings, etc.) in the forest because there is more places to camouflage and make burrows. I hope you have fun in Nova Scotia!

  16. Hi Ms. Davis!!
    I think that you will catch more mammals in the twig/wooded section, because the mice and vole prefer that sort of area.

  17. I think that you will find the most in the meadows because rodents usually like to burrow in the ground so if they were to be in the woodlands, there wouldnt be a lot of flat ground to burrow in.
