The origin of red flowers: genetic mechanisms, ecological drivers and macroevolutionary patterns

Smith_headshot
Dr. Stacey Smith Presents:

Tuesday March 24th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

Angiosperms display an incredible diversity of flower colors, although relatively little is known about macroevolutionary trends in flower color and the genetic basis for different classes of color transitions. My talk will focus on the distribution of red flowers and the genetic basis for the origin of this trait.  Studies in a handful of taxa, including […]

Dr. Emily Moriarty Lemmon Presents:

Tuesday April 7th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

Reproductive interactions among species represent a powerful evolutionary force driving diversification, particularly when organisms interact with a mosaic of other taxa across their geographic distribution. Theory predicts that spatial variation in community structure can lead to divergent selection on reproductive behaviors across geography, when different phenotypes are favored in different species assemblages. A critical outcome […]

*BSPM Seminar* Anchored phylogenomics: rapidly expanding across the Tree of Life

Dr. Alan Lemmon Presents:

Wednesday April 8th, 2015 at 12:00 noon in Plant Sciences Building E008

Hybrid enrichment is quickly becoming the preferred method of phylogenomic data collection, because it allows hundreds or thousands of nuclear loci to be obtained at a lower cost than other approaches. Anchored hybrid enrichment, by utilizing probes representing several diverse lineages within a target clade, is particularly powerful because it allows researchers to target loci […]

**PhD Seminar** Testing the effects of gene flow on adaptation, fitness, and demography in wild populations

**PhD Seminar** Flexibility and constraint in the evolution of gene expression and behavior

252
Eva Fischer Presents:

Tuesday May 5th, 2015 at 4:00 PM in Anatomy/Zoology Building W118

Two fundamental unsolved problems in evolutionary biology are (1) predicting how genotype and environment interact to shape evolutionary processes and (2) elucidating the mechanisms by which genetic and environmental influences produce well-adapted phenotypes. Central to these questions are contrasting views on how environmentally induced variation (phenotypic plasticity) influences adaptive evolution, and how selection in a […]

**PhD Seminar** Legend, history, and ethnobotany as a basis for testing alternative hypotheses on the origin, dispersal, evolution, and chemistry of Catha edulis (qat)

264
Luke Tembrock Presents:

Wednesday May 6th, 2015 at 4:00 PM in Yates 206

Catha edulis (Vahl) Forssk. ex Endl. (qat, khat, mirra) is a woody plant species that is grown and consumed in East Africa and the southern Arabian Peninsula for its stimulant alkaloids. The alkaloids responsible for the stimulant properties are cathinone, cathine, and norephedrine. These alkaloids are structurally and pharmalogically similar to amphetamines. The evolution of […]
