Hi! My name is Ms. Dosmann. Please travel with me to Nova Scotia to study Climate Change and Mammals.

Thanks for your comments!

First, Ms. Stiffend's class, I am as alert for your similes as the coyote was for us as he jumped into the woods today.

Great science starts with a question... and you asked some GREAT questions today. I'm very impressed!

Vole Babies - How long does it take to have a vole baby?
I had to go ask Dr. Chris about vole babies to make sure I get the information correct for my inquisitive students. Baby voles grow in their mother's tummies (this is called the gestation period) for 18 to 19 days before they are born. Voles have litters of 3 to 6 babies at a time. They get milk from the mother vole for 14 days after they are born. Then, when they are 4 weeks old, they can go out and make babies of their own. Remember that voles do not live very long in the wild, so they have to reproduce (make new babies) very young. How does this compare to humans? You could do a great Venn diagram to compare.

Cow Skull
Zora got it right! The cow was shot. You can see the hole in his head. I'm not sure why the cow was shot. Good detective work, Zora!

Checking the traps twice
Ciara was close on this one! The reason we check the traps the twice each day is to make sure the small mammals aren't in the traps too long. Like Ciara said, it might be too cold or the animal might not have enough food. Some animals get very scared in the traps and this can be bad for them. The scientists are careful to only trap the animal long enough so that they can collect data and then release it into its habitat alive and well. Nice work!

Deer Antlers
Great work! One use for antlers is protection. If a buck (a male deer) is threatened, it can use its antlers to protect itself. Another important use for antlers is to show other deer who is the biggest, strongest and healthiest buck. Only the strongest buck becomes the leader of its herd. This buck passes on good traits to his young. Big antlers show that the buck is healthy, strong and smart. Bucks with small antlers won't mess with a buck with bigger antlers. It's kind of like people. A skinny little guy isn't going to mess with a big, muscular man! So, that's why antlers are so important. Pretty neat.

I can't wait to read your comments and questions tomorrow! Only two more days left in the field...
