The Kaspari Lab
Mike’s Favorites:
Papers are stories with backstories. Here are a handful of mine that I really like, and a little about why.
Kaspari M and A Joern (1993) Prey choice in three grassland birds: reevaluating opportunism. Oikos 68:414-430
In the late 70s and early 80s John Wiens and John Rotenberry wrote an influential set of papers suggesting grassland birds ate pretty much whatever they encountered. After spending much of the early 80’s watching birds and catching bugs in the Sandhills, Tony and I rebutted that notion.
Kaspari M & M Byrne (1995) Caste allocation in litter Pheidole: lessons from plant defense theory. Behavioral Ecology and Sociobiology 37:255-263
The first paper on my favorite genus, and one that tried to extend theory from another field to my new favorite taxon: ants. Note to self: if you want myrmecologists to read a paper, make sure the word “ants” is in the title.
Kaspari M, S. O’Donnell, & L Alonso (2000) Three energy variables predict ant abundance at a geographic scale. Proc of the Royal Society B 267:485-490
The first paper out of our “49 ant communities” project that established what was to be our lab’s modus operandi: test theory on a geographic scale by going into the field and collecting the data.
Yanoviak, S & M Kaspari (2000) Community structure and the habitat templet: ants in the tropical forest canopy and litter. Oikos 89:259-266
The first in a long productive collaboration with Steve Yanoviak that started us integrating the physical structure of the environment and stoichiometry of ant and food supply to predict how ant communities behave.

How often do you get to honor an academic grandfather and present to the world a piece of art that captures the idea of MacArthur’s Warblers? Debby Kaspari’s illustration is now used to teach MacArthur’s work all over the world.
Kaspari, M, S Yanoviak, R Dudley. (2008) On the biogeography of salt limitation: a study of ant communities. PNAS 105: 17848-17851
When those ants began to swarm our NaCl baits it was one of the most exciting things I had ever seen. The trio of Dudley, Kaspari, and Yanoviak have always managed to combine travel to interesting places with unexpected discovery. All our salt work started with this one.
