Independent Study: Geography of Speciation — Fall 2017

This is an independent reading course that I have designed for Kevin Hawkins, a PhD student in my lab. It is tailored to give Kevin an historical, broad, and also deep perspective on the current state of thinking about the geography of speciation, especially as it relates to North American birds (since Kevin’s thesis focuses on speciation in a North American bird complex). While many of these readings would be considered canonical, they also represent papers/systems (e.g. Heliconius) that have influenced my thinking about speciation. Likewise, many obvious papers were excluded because of Kevin’s existing familiarity with the topic.

For the independent study, I will be meeting with Kevin once a week for 60 minutes. During that meeting we will discuss the three papers. 24 hours before our meeting, Kevin will provide me:

  • A printed copy of each paper that shows highlighting and annotations.
  • A summary of the paper. In the style of Jonathan Tonkin
  • A list of three key points of observations. Written in sentence style. Two to four sentences per observation.

Kevin and I will meet once a week, for 11 weeks. Time and day of the week to be determined.
