Refugial Brown Bag

The brown bag on 4/24/2013 by Yadeeh Sawyer was titled “Living on the Edge: Testing the Coastal Refugia Hypothesis”. Ms. Sawyer looked at post glacial lineages in Microtus longicaudus and the responses to historic climate, demographic change, and underlying evolutionary processes. She also looked at diversification of northern Peromyscus and tried to determine drivers of diversification in high latitude climates by looking at island size and isolation and changes in diversity. However, Ms. Sawyer focused on the coastal refugia roles in shaping island diversification. She asked how historical climate events and the degree of insularity impacted contemporary mammalian phylogeographic structure. She looked at spatial and temporal species distribution by looking through primary biogeographic forces such as size, isolation, topography, and history (glaciers, sea level, climate). She made sure to note that the effects of all of the first three forces were dynamic, constantly changing systems. The systems were represented as oceanic, continental land/bridge, sky islands, and fragmented habitat. Ms. Sawyer believes that glaciation caused populations to move north south or to coastal refugia but as ice melted they could move away from refugia leading to today’s distributions. She found that beringian sources moved south, mainland sources moved north, and coastal sources increased on the continental shelf. She then hypothesized that genetic signatures will reflect glacier refugia and refugal populations were the source for post glacial colonization. She looked at mitochondrial DNA and found that outgroups were all on the same long branch. She found that non refugial locations had higher diversity but that her hypotheses were opposite for the vole, suggested expansion for the shrew, and were expected for the mouse. The vole and shrew showed strong support for glacial isolation, but the mouse did not. The mouse and shrew were stable in refugia which was opposite of what was expected. She didn’t identify source populations. In the future she would like to test other hypotheses, include nuclear data, species trees, ABC tests, migration rates and direction. This was a very interesting talk though I felt confused by most of it. I wish I had had time to go through her data more slowly because I believe that her research is very interesting and will probably be very important to historical biology.


Final Project Summary

I actually made this video before I realized that it could be submitted as an extra credit video. I addressed the problems I had vlogging which was a major portion of my final project.

PeopleWater A Project in the Making


This is the first interview that I had with PeopleWater NMSU Campus Ambassador, Jordan Lohkamp. During this Facetime call she offered to send me packet of stickers and pamphlets for my project.


While I waited for Jordan’s package, I researched PeopleWater through their Facebook, Twitter, and company page.


Later that same week Henry cat and I went to check the mail and we found that Jordan’s package had arrived!


This is the contents of what Jordan sent to me. I took these to UNM with me after I interviewed people about their knowledge of PeopleWater.


These are some of the people that had heard of PeopleWater (yay!).


And these are some of the people that had not heard of PeopleWater.


It took a ton of tries for me to feel comfortable on camera.


But, despite my fear of videos and my awkward interview attempts, I ended up with a very interesting project, a greater knowledge of a powerful organization, and was able to inform more people around the UNM campus about a good cause.


Thanks to everyone who helped and participated in this project. I hope that UNM gains a Campus Ambassador and that my working on this project helped PeopleWater gain a few more customers.




The Future of PeopleWater

This is an interview with a UNM student, Tanya Chandhok, who is interested in becoming a PeopleWater Campus Ambassador at UNM.

How PeopleWater Changed Me

ImageChoosing PeopleWater as the local organization for my final project has been eye opening. Jordan has been part of the organization for over a year now and while I was always very proud of her and interested in her cause, I never really thought about the company further than that.

On day one of this project, as I looked into the social media of PeopleWater I realized that it was a very powerful idea and an organization with the potential to change many lives. As I thought about the company in a more local sense I realized that personal communication with the leaders and ambassadors was essential to spreading the word. I thought that people would know about the company from the Bachelor or social media, but as I interviewed people on campus I realized that many people were unaware that PeopleWater even existed.

While there were very few people that had heard of PeopleWater, everyone I spoke to said it sounded like a good cause and they would be interested in learning more about it. I am graduating this semester and unfortunately don’t have the opportunity to bring PeopleWater to UNM, but a friend of mine, Tanya, has a semester left at UNM and says that she would be interested in becoming an campus ambassador. We’ve been talking a lot about the organization as I’ve worked on my project and Tanya’s interest grew as mine did.

I am so excited to have had this little impact on the prosperity of PeopleWater at UNM. I believe that because I am friends with Tanya if she is appointed to be the PeopleWater Campus Ambassador for UNM I can help her by giving her my social media audits and other information that I have collected about the organization to help it succeed on our campus. I look forward to watching this program grow in the future and I think that it will because it has so many opportunities to spread the word.


Major Players Minor Settings

This is a video talking about how the major players social media and national aspects of PeopleWater influence the responses of local PeopleWater associates.


Spreading the Word

This is a Q&A with students around UNM about their knowledge of PeopleWater. The interview process definitely had a few hiccups along the way that I will discuss in next weeks blog.
