This is the home page of the UConn EEB department's Systematics Seminar (EEB 6486). 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.

Meeting time and place
We are meeting this semester in the Bamford Room (TLS 171B) Tuesdays 4-5pm (except Sept. 6, when we will meet in TLS 154; see below)
Schedule for Fall Semester 2011
Several themes were identified for this semester's Systematics Seminar. We will spend 2-3 weeks on each one.
- Ancestral state reconstruction
- Use of niche modeling in delimiting species
- Informativeness of genes
- Cryptic species
Tuesday, September 6, 2011
We will attend the special seminar by Chris Bird, an EEB BS alum and presently a postdoctoral associate at the University of Hawaii. The talk will be at 4 pm in TLS 154, and is entitled “Sympatric Speciation on the Seashore.”
Tuesday, September 13, 2011
Eric Schultz will lead a discussion of the following paper:
- Whitehead, A. 2010. The evolutionary radiation of diverse osmotolerant physiologies in killifish (Fundulus sp.). Evolution 64(7): 2070-2085. doi:10.1111/j.1558-5646.2010.00957.x.
Note: you will need a user name and password to access the PDF above. These were sent out via the Systematics listserv on Sept. 6, 2011, but feel free to write to Paul Lewis if you missed it.
Tuesday, September 20, 2011
Karolina Fučíková will lead a discussion of the following paper:
- Nagy et al. 2010. The evolution of autodigestion in the mushroom family Psathyrellaceae (Agaricales) inferred from Maximum Likelihood and Bayesian methods. Molecular Phylogenetics and Evolution 57:1037-1048.
Tuesday, September 27, 2011
Chris Owen will lead a discussion of the following paper:
- Tsang et al. 2011.pdf. Hermit to King, or Hermit to All: Multiple Transitions to Crab-like Forms from Hermit Crab Ancestors. Systematic Biology 60:616–629.
I have also included the classic Cunningham et al. 1992 paper, which originally proposed the "Hermit to King" hypothesis (short and worth the read) and another paper from the Cunningham group that uses DNA and mtDNA gene rearrangements to explore the phylogeny of decapods and the evolution of the crab-like form.
- Cunningham et al. 1992.pdf. Evolution of king crabs from hermit crab ancestors. Nature 355:539-542.
- Morrison et al. 2002.pdf. Mitochondrial gene rearrangements confirm the parallel evolution of crab-like form. Proc. R. Soc. Lond. B 269:345-350.
Tuesday, October 4th, 2011
Beth Timpe will lead a discussion of the following paper:
Bayesian estimation of ancestral character states on phylogenies. Syst. Biol. 53(5):673–684, 2004.
Tuesday, October 11th, 2011
Don Les will lead a discussion of the following paper:
Cryptic Species, Species Delimitation, and Taxonomic Practice in the Homosporous Ferns. American Fern Journal, Vol. 79, No. 2.
Tuesday, October 18th, 2011
Hamid Razifard will lead a discussion of the following paper:
"Genetic diversity and taxonomy: a reassessment of species designation in tuatara (Sphenodon: Reptilia)". Conserv Genet (2010) 11:1063–1081.
The authors provide a good review of the previous studies (using allozymes, mtDNA) with conflicting results. They also provide a thorough analysis of all sampled tuatara populations using different techniques (microsats, mtDNA, and PCA on allozyme data obtained by others). The paper is good example of getting different results using different techniques, since the markers probably have different evolutionary. Therefore, using various techniques (and not focusing on a few evidence from morphology, or molecular data) seems necessary for future taxonomic studies.
