Rufous-collared Sparrow:

High-altitude Adaptations

With a large variation in elevation amongst populations, the Rufous-collared Sparrow also shows a corresponding variation in gene regulation between these populations. High altitude populations show up-regulation in genes associated with metabolic and signal transduction pathways when in direct comparison with low-altitude populations. This up-regulation and expression are plastic, as found when high-altitude and mid-altitude birds were brought to lower elevations and both populations showed a decrease in regulation, eventually matching each other. In earlier research, it was concluded that the differences between regulation in populations was due to temperature regulation, rather than ability to handle hypoxic conditions.

Week 2: Write a sentence or two about what you learned from the training modules

- Aside from learning about the basics of Wikipedia and what is expected when editing, I also learned that that Wikipedia and editors have their own "jargon." Things such as edit wars came up in the modules and I found it interesting.
