Ready, Set, Go!

We are technically about to start week 4 of the summer around here (!), but I feel like I am still trying to get in gear. The REU students have arrived and I think we have another excellent group. We assign our student-mentor teams into research clusters. Sometimes these clusters work collaboratively and other times we are grouped by a common interest. I am part of the “Landscape and Ecosystem Ecology” cluster with four other faculty and three other students (in addition to mine). We meet in our clusters about once a week during the summer and discuss research articles and what progress we are making on our projects. My student will be working on part of my USDA grant to map Amur honeysuckle. She will do some field work, but will spend a lot of her time learning about and using remote sensing and image processing. For students who do not have a strong background in remote sensing, I usually start out by having them go through the labs from my remote sensing class to get up to speed. We will use this week to get going on that.

I am still debating about exactly what to have her work on this summer. I have been considering using MODIS data to monitor vegetation phenology in our area from year to year. This would be useful for determining when the honeysuckle comes into leaf. This invasive shrub expands earlier in spring and retains leaves later in the fall than native trees and shrubs, so we are using satellite imagery from those two time frames to map abundance. It has been challenging to determine the optimum window each year, however, so I have been wondering if MODIS might help. There is still more work to do with Landsat images (what we have mostly used so far), so I have to decide which direction to go. I also wanted to give her some latitude in deciding how much to focus on field work and how much time to spend in the computer lab, so we’ll see! The REU students are only here for 10 weeks, so it is critical to keep these projects a manageable size and scope. This week will be a chance to lay out a feasible research plan. It should be fun!

Important Advice for College Students Regarding Grades

By -
The semester has just ended and I have received emails from several students inquiring about their grades.  Most of these emails have asked me to reconsider the grades that I reported to the university registrar and are now released to students.  These emails have become increasingly more common and also more brazen in their requests/demands.  I would like students to think long and hard before sending these end-of-semester emails and consider a few questions: Did you attend this class? If you answer "yes", but you missed more than 10% of class meetings (in my classes this would amount to missing more than three out of our 27 class meetings), how many classes did you miss?  Did you miss them for a family emergency? Due to illness? Or because you overslept or had more important things to do? Most of us have policies that allow flexibility for illness and family emergencies.  It is also good to learn what university offices can assist you with these matters. At...

Summer Plans

By -
We've reached the halfway point of the summer here at Miami (we start classes on August 24th), so it seems like a good time to take stock of what I've accomplished and what I still plan to do this summer. Progress Most of my work this summer has focused on REU and with the help of my student, we have made some good progress on a project. After some debate, I decided to stick with using some methodology that we've already used in this research, but apply it to different data. Most of the work done so far on this project (and the pilot study before the grant) focused on using fall imagery to detect Amur honeysuckle in forested areas. This shrub expands its leaves earlier in spring and retains them later in fall than the overstory tree species, and thus far, we have used fall imagery in our analysis (we felt that too many other plants were also green in spring). Recently, I started to reconsider this approach and tested some spring images for a conference presentation this spr...

Getting back into the groove

By -
My job can be really funny in some ways. I go from having ultimate flexibility in the summer to the structure and schedule of the semester. There is no transition. One day, I just get up and classes are back in session. I am teaching mornings this semester, so I have gotten back into a schedule of getting up early and coming into campus to teach. My afternoons are more open for labs, meetings, research, class planning, etc. and by 10pm, I am pretty wiped out. The first week back is always a shock to the system- I slept for 10 hours last Friday night! Once I get back into a routine, things are fine. I feel pretty good about how my classes are going so far. In my intro physical geography class, I am trying online quizzes for the first time. Every Monday morning, a new quiz is up for the students to take and they have until Friday night at 10pm to finish them. They are graded automatically, since I have the correct answers built into the quiz. There were a few technical glitches for the f...
