Stuart Wagenius « The Echinacea Project

Christine Dumoulin graduates

15 March 2011 Christine Dumoulin defended her Master’s Thesis in Plant Biology and Conservation at Northwestern University. Congratulations! For her thesis project, Christine developed a computer simulation model to investigate how dominance relationships among S-alleles influence mate availability and reproduction in small populations. Christine is already pursuing her PhD in Ecology and Evolutionary Biology at the University of Tennessee.

Lesson plan published

11 Jan 2011 Greg Diersen describes his adventures with Team Echinacea and presents a lesson plan in a new paper: Diersen, G. T. 2011. Team Echinacea & construction of a key using online images of fresh prairie plant pollen. The American Biology Teacher 73:35-38. PDF

NSF funding to continue

In early December, NSF informed us that The Echinacea Project will be funded from April 2011 – April 2016!

Jennifer Ison graduates

21 September 2010. Jennifer Ison defended her dissertation on Friday and gave a public seminar to a packed house at UIC on Tuesday. Congratulations! Her dissertation title is “Pollination of Echinacea angustifolia: effects of flowering phenology and spatial isolation.” Jennifer started with the Echinacea Project in 2003, right after graduating from St. Olaf College. She is heading to a post-doc position with Art Weis in Toronto, starting 1 October.

end of harvest

Only about 13 heads left to harvest in the common garden experiment! I attached a pdf of listing all heads with no gbag info…

Here’s a map of unharvested head locations in the main experiment (there’s one more head in the 99S garden).

barplot

Here’s a draft of two barplots that Hillary asked me to whip up using R magic. I’ll let her explain what they mean.

new script for Hillary

hillaryLookAtAphids2.r

explore growth of aphid clones

This R script, hillaryLookAtAphids.r, allows one to view graphs of growth of aphid clones in Lauren and Hillary’s experiment.

Stipa tag found

Tag #1028 was just found in the ground near the SW corner of Hjelm house porch.

file for Ian’s phenology analysis

Ian wants to quantify the overlap of flowering time between all pairs of plants in his experiment. This following R script reads his file with the flowering schedule of all 31 plants in his experiment and writes a file called ianPhenPairs.csv that has the flowering schedule of every possible pair combination (one per line). Note that there is a separate record for each plant as a sire and dam.

# script ian.phenology.r

pp <- read.csv("https://echinaceaproject.org/wp-content/uploads/ian.phenology.final.csv")

str(pp)

p <- merge(pp,pp, by = NULL)

str(p)

31^2 == dim(p)[1]

write.csv(p, “ianPhenPairs.csv”, row.names = FALSE)
