After a certainly unique summer featuring many adjustments but also many great online conferences, classes are back in session at UR. To bring back something familiar, here are the papers that will be discussed during this week’s Journal Club on Tuesday the 15th at 11:05 (see department emails for access to the zoom link).
The focus is on the Bateson-Dobzhansky-Muller Model and will include a classic 1936 paper by Theodosius Dobzhansky, “Studies of hybrid sterility. II. Localization of sterility factors in Drosophila pseudoobscura hybrids” and a 1995 by our own Allen Orr, “The population genetics of speciation: the evolution of hybrid
Last Thursday the Chen and Meyer labs set up booths at Wayne Central Middle School for the Science Now Expo. The night was a chance for students of the middle school and their parents to talk to members of the local STEM community and see some of the demonstrations. The booths included a guessing game of genetic inheritance, 3D printing, and a box of live bumblebees!
The department is celebrating the end of another semester with holiday parties, cookie making, and graduate student stacking, apparently. This feat of strength was part of the annual celebration of Festivus hosted by Dr. Justin Fay.
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Lindsey and Songeun will be presenting these papers:
“Disruptive selection and the genetic basis of bill size polymorphism in the African finch Pyrenestes” by Smith (1993)
“Growth factor gene IGF1 is associated with bill size in the black-bellied seedcracker Pyrenestes ostrinus” by vonHoldt et al (2018)
“Divergence and Functional Degradation of a Sex Chromosome-like Supergene” by Tuttle et al (2016)
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Rose and I will be presenting these papers:
“Barson et al. 2015. “Sex-dependent dominance at a single locus maintains variation in age at maturity in salmon”
Ruzicka et al. 2019. “Genome-wide sexually antagonistic variants reveal long-standing constraints on sexual dimorphism in fruit flies”.
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Songeun and Lauren will be presenting these papers: “Rapid and adaptive evolution of MHC genes under parasite selection in experimental vertebrate populations.” by Eizaguirre et al., 2012 and “Immunogenetic novelty confers a selective advantage in host-pathogen coevolution.” by Phillips et al., 2018.
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Emery and Rose will be presenting these papers focusing on negative frequency dependent selection: “Mating advantage of rare males in wild guppy populations” by Hughes et al., 2013 and “Herbivore-Mediated Interaction Promotes the Maintenance of Trichome Dimorphism through Negative Frequency-Dependent Selection” by Sato and Kudoh, 2017.
Last week many people in the department got involved in some holiday festivities. Whether it was handing out candy in Hutchinson Hall for the Society of Undergraduate Biology Student’s trick-or-treating, carving pumpkins, or just getting dressed up in costume, we had a spooky time!
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Omid and I will be presenting the papers “Genomic Evidence of Rapid and Stable Adaptive Oscillations over Seasonal Time Scales in Drosophila” by Bergland et al. (2014), and “Signatures of Environmental Genetic Adaptation Pinpoint Pathogens as the Main Selective Pressure through Human Evolution” by Fumagalli et al. (2011).
Please join us this Tuesday at 11:05 – 12:15 in Hutch 316. Emery and Omid will be presenting the papers Field et al., 2016 “Detection of human adaptation during the past 2000 years” and Uricchio et al., 2019 “An evolutionary compass for detecting signals of polygenic selection and mutational bias”.
