More population genetics of polyploidy!
I did a literature search today and found several interesting papers. I picked two for next week, but in the interest of time, I think we should focus on the first one (Walsh paper). The Comai paper can be background reading for people who want to do a little polyploidy catch-up (like me). Both Genetica and Nature Reviews Genetics are available online through the library.

Ploidy shifts with Pat and Brian.
The yeast haploid superiority article (Zeyl, 2003, Science below) dovetails nicely with the Walsh reading from April 17 and the Otto review from April 10.
A recent paper on gene duplicate evolution in Teleost fish should further expand on experimental observations related to evolution specific to polyploid contexts.

Speciation with Dena
Great paper from the Solti, Pires, and Leitch groups from a meeting proceedings at Kew Gardens. Demonstrates that in this case the species barrier was not overcome just once in a freak accident.
Polyploid tree frogs unite to form a complex interspecies swarm. Demonstrates recurrent polyploid formation can play a role in animal polyploid speciation too. Go frogs.
