We investigated how plant species' responses to soil texture might affect coexistence by analysing distributions, seedling emergence and performance, and competitive abilities of the winter annuals Clarkia speciosa ssp. polyantha and C. xantiana ssp. xantiana.
Article arguing that undergraduate curricula should incorporate new approaches to economics including game-theory and other advances in economic analysis
To promote reproducibility, since 2009 all my empirical research has been cached in a data repository that captures all source code and data dependencies automatically or semi-automatically.
Provides information about locally produced foods in the Grinnell (Iowa) area and includes a listing of area producers and the foods they raise and sell.
The mathematical parallels between electrostatics and laminar fluid flow are exploited to develop a set of exercises that allow introductory physics students to discover Gauss's Law.
We report fndings of reciprocal transplant experiments intended to tease apart the roles of differentiation and plasticity in producing phenotypic variation across a geographic border between two plant subspecies. Clarkia xantiana ssp. xantiana and C. xantiana ssp. parvifora are California-endemic annuals that replace each other along a westG??east gradient of declining precipitation.
