This is the home page of the UConn EEB department's Systematics Seminar. This is a graduate seminar devoted to issues of interest to graduate students and faculty who make up the systematics program at the University of Connecticut.
Contents
Meeting time and place
We are meeting this semester in the Biopharm 3rd Floor Fishbowl Mondays and Tuesdays 2-3pm.
Subtopic Ideas for the rest of the semester (please bring additional ideas to seminar):
SPECIATION 1) What did Darwin say about speciation and hybridization? (First week) 2) When does a species become a species? How can the earliest stages of speciation be recognized? 3) How much genetic divergence should we expect within species? Are large genetic divergences within species due to polymorphisms/large population sizes, or artifacts, or are they simply due to our failure to recognize cryptic species? 4) Are there "speciation genes"? What are some examples? Are speciation genes restricted to a certain type of mutation or class of genes?
HYBRIDIZATION: It has been estimated that at least 25% of plant species and 10% animal species hybridize* 1) How much gene flow occurs across species boundaries and what are the consequences for species? 2) How can lineage sorting be separated from hybridization as a cause for phylogenetic uncertainty? 3) How important is hybrid speciation in nature 4) Conservation Biology: Should hybrids be shot or poisoned? Or not?
