Hey everyone!
This week in in journal club we will be discussing how phenotypic plasticity affects rates of gene evolution. Feel free to swing by room 316 at 12:30.

This semester journal club will first focus on phenotypic plasticity. We will be reading the following papers next week:

(Optional: if you want more background read Scheiner S.M. 1993. Genetics and evolution of phenotypic plasticity. Annu. Rev. Ecol. Syst. 24: 35-68)
This week we will be reading two papers by faculty candidate David Platchetzki. His research focuses on Cnidarian sensory evolution.
The evolution of phototransduction from an ancestral cyclic nucleotide gated pathway. Proc. R. Soc. B 2010
Cnidocyte discharge is regulated by light and opsin-mediated phototransduction. BMC Biology 2012
Next week, we will discuss about the future of speciation research. Two papers we are going to discuss are listed below.
Presgraves, DC. Darwin and the origin of interspecific genetic incompatibilities. 2010. Am. Nat. 176:S45–S60. [link]
Sobel, JM. et al. The biology of speciation. 2009. Evolution. 64:295–315. [link]
Next week, we will continue our discussion in genetics of speciation using genomic methods. The three papers we are going to discuss are listed as follows:
Turner, T.L., Hahn, M.W. & Nuzhdin, S.V. 2005. Genomic Islands of Speciation in Anopheles gambiae. PLoS Biol 3, e285. [doi link]

Next week, we will continue with the genetics of speciation, focusing on the role of chromosome rearrangements. The three papers we are going to discuss are listed below:
This week we will revisit Allen’s 1995 paper and discuss hybrid incompatibilities. We will also discuss Allen’s 1997 review about Haldane’s Rule.
-Orr, H.A. 1997. Haldane’s Rule. Annu. Rev. Ecol. Syst. 28:195-218
We will now shift the focus of Journal Club to the genetic mechanisms of speciation. We will read Coyne & Orr 1989 about the patterns of speciation in Drosophila and Allen’s 1995 paper about the evolution of hybrid incompatibilities.
