This is a page where I'll put up powerpoint or pdf files from presentations I've given, for your
edification and/or amusement. For the most part they should make sense even without me standing
up in front of you talking, though I like to think the talking part adds something to the
experience. Presentations are listed in reverse chronological order. Note that some of the powerpoint
files will not be formatted correctly unless you happen to have
Igino Marini's Fell Types installed. Also, powerpoint files often have associated notes that may provide
Presentations for Academic Societies
Further adventures in the phylogenetics of
A talk presented at the 2010 Botany Meetings in Providence, Rhode Island. An updated version of the talk
given for the 2009 Botany Meetings, with about twice as much data.

in Boechera fendleri s.l. (Brassicaceae)

progress towards a phylogeny of Boechera (Brassicaceae)
A talk presented at the 2009 Botany Meetings in Snowbird, Utah.
Leucaena using SAIKS (SLIKS-Alike Interactive Key Software)
A poster presented at the 2008 Botany Meetings in Vancouver, British Columbia. It has
also made appearances at the state meetings of the New Mexico & Arizona native plant
societies (Sep 2008 & Feb 2009).
what is the problem & why is it still here?
A talk presented at the 2007 Willi Hennig Society meeting in New Orleans, Louisiana. A rather
disjointed thing in hindsight. Oh well.
Ecology of C3 and C4
Grasses (Poaceae) in the United States: a Phylogenetically Controlled
A poster for the Botany Meetings in Chico, CA, beginning of August, 2006. This is an
extension of a class project for Evolutionary Ecology, taught by Dr. Kathy Hanley.

and Thysanocarpus (Brassicaceae)
A presentation for the Botany Meetings in Chico, CA, beginning of August, 2006.
Presentations for Other Groups
Sexual behavior in plants:
autoeroticism, ménages á trois, and other deviations
Presented at the state meeting of the Native Plant Society of New
Mexico, September 2011.
Why do names change?
Examples from Brassicaceae
Presented to the Santa Fe chapter of the Native Plant Society of New Mexico,
January 2011. This is basically a modified version of the November 2009 talk. I'm not sure if it's
better or worse.
The "how" and "why" of botanical
A talk for the Las Cruces chapter of the Native Plant Society of New Mexico,

for the Natural History Museum of Las Cruces in March 2009.
Flora of New Mexico
A talk for Las Cruces' Academy for Learning in Retirement, mid-2007, giving a little bit
of history of NM botanizing & some plant communities & species throughout the state, from
low to high elevations. Not much text, mostly pretty pictures.
Group selection, inclusive fitness, and ants
Brown bag talk for the NMSU Department of Biology, February 2007. Since then,
a number of papers in favor of group selection over inclusive fitness have come out.
Botanizing in Baja
An overview of my October 2006 trip to Baja California with Rich Spellenberg, Al Kruger,
& the Killingbecks. Presented for the Las Cruces Chapter of the New Mexico Native Plant
Society, February 2007.
Ferns of New Mexico
A talk for the Santa Fe Chapter of the New Mexico Native Plant Society, September, 2006.
An expansion on the earlier Organ Mts. fern talk, for the most part. There is at least
one factual error; see if you can find it!
Species: a Wittgensteinian
Brown bag talk for the NMSU Department of Biology, March 2006. One of my early "a powerpoint
presentation is just a written paper but, you know, in powerpoint" talks.
Ferns of the Organ
This is a talk I gave to the Las Cruces Chapter of the New Mexico Native Plant
Society in February, 2006.
