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

Day 9 - Monday, Cook's Lake

Today we went to a new research site. Dr. Christina's family owns some land around a lake that is further inland than East Port Medway. Inland means that it is away from the coast. This means we get to see a different habitat for small mammals. A different habitat means there might be different animals. Why might the species of animals change when we move to a different habitat?

On the long drive to Cook's Lake, we had a great surprise. We saw a bobcat! It was the first bobcat that Dr. Christina has ever seen in Nova Scotia. What do you know about bobcats? We didn't get our cameras our quickly enough, so I googled a picture for you. Later that day, we saw other field signs of bobcats. We saw fresh (within half an hour!) bobcat scat, a feeding site and even some bobcat tracks. It is rare to see bobcat scat because they usually bury it, just like a house cat. Can you hypothesize why a wild cat might bury its scat?

We hiked to our research site down a long trail. Along the way, Dr. Christina showed us some field signs she has found in the area. She had us guess what we thought they were. I'll post them here and let you hypothesize. What animal do you think these skeletons came from?

After the long hike, we arrived at the research site. This site was less rocky than at East Port Medway. Part of it was like a field of hay and then it turned into a forest. We prepped and set the 100 traps again. Dr. Christina says we might catch woodland mice, jumping mice, red-backed voles, chipmunks and squirrels. I want to catch a jumping mouse. They have extremely long tails and large feet. Dr. Christina says that more of this type of mouse survives the winter. They aren't sure why yet. Do you have any hypotheses why having a long tail and large feet would help a mouse survive better?

Look below for answers to your questions. You have been doing a GREAT job commenting!

Ms. Dalton's D.I. Class has a hypothesis about why a jumping mouse survies the winter better than the other mice. We think that the jumping mouse, with his long tail and large feet, survive the winter because their large feet help them dig holes quicker to get away from their predators. Also, the large feet will help him survive the winter by helping him walk/run/jump faster across the snow to get away from his predators.
Have a great day, Ms. Dosmann, and we look forward to your next blog!
P.S. When will you be coming back to Atlanta?
