Meeting time and place

We meet at 11:05 in the Bamford Room (TLS 171B)

Theme and Schedule for Fall 2018

We will largely be discussing papers on character mapping, reticulation, and biogeography+dating. Any students that would like to sign up to present a practice talk or talk through ideas related to their research are encouraged to do so!

Information for discussion leaders

Seminar Format: Registered students be prepared to lead discussions, perhaps more than once depending on the number of participants.

The leader(s) will be responsible both for (1) selection of readings, (2) announcing the selection, (3) an introductory presentation, (4) driving discussion and (5) setting up and putting away the projector.

Readings: In consultation with the instructors, each leader should assign one primary paper for discussion and up to two other ancillary papers or resources. The readings should be posted to EEBedia at least 5 days in advance.

Announcing the reading: The leader should add an entry to the schedule (see below) by editing this page. There are two ways to create a link to the paper:

1. If the paper is available online through our library, it is sufficient to create a link to the DOI:

:[ Doyle et al. 2015. Syst. Biol. 64:824-837.]

In this case, you need not give all the citation details because the DOI should always be sufficient to find the paper. The colon (:) at the beginning of the link causes the link to be indented an placed on a separate line. Note that the DOI is in the form of a URL, starting with Here is how the above link looks embedded in this EEBedia page:

Doyle et al. 2015. Syst. Biol. 64:824-837.

2. If the paper is not available through the library, upload a PDF of the paper to the UConn dropbox, being sure to use the secure version so that it can be password protected. Copy the URL provided by dropbox, and create a link to it as follows (see the Dropbox Test page for other examples):

:[ Doyle et al. 2015.]

In this case, you should provide a full citation to the paper for the benefit of those that visit the site long after the dropbox link has expired; however, the full details need not be part of the link text. Here is what this kind of link looks like embedded in this EEBedia page:

Doyle et al. 2015. Full citation: Vinson P. Doyle, Randee E. Young, Gavin J. P. Naylor, and Jeremy M. Brown. 2015. Can We Identify Genes with Increased Phylogenetic Reliability? Systematic Biology 64 (5): 824-837. doi:10.1093/sysbio/syv041

If you have ancillary papers, upload those to the dropbox individually and create separate links.

Finally, send a note to the Systematics Listserv letting everyone know that a paper is available.

Introductory PowerPoint/KeyNote Presentation: Introduce your topic with a 10- to 15-minute PowerPoint or KeyNote presentation. Dedicate at least 2/3 of that time to placing the subject into the broader context of the subject areas/themes and at most 1/3 of it introducing paper, special definitions, taxa, methods, etc. Never exceed 15 minutes. (For example, for a reading on figs and fig-wasps, broaden the scope to plant-herbivore co-evolution.). Add images, include short movie clips, visit web resources, etc. to keep the presentation engaging. Although your presentation should not be a review of the primary reading, showing key figures from the readings may be helpful (and appreciated). You may also want to provide more detail and background about ancillary readings which likely have not been read by all.

Discussion: You are responsible for driving the discussion. Assume everyone in attendance has read the main paper. There are excellent suggestions for generating class discussions on Chris Elphick’s Current Topics in Conservation Biology course site. See section under expectations.

Prepare 3-5 questions that you expect will spur discussion. Ideally, you would distribute questions a day or two before our class meeting.

Projector: The Bamford room has joined the modern world--you should just need to plug in your computer or USB key to project.
