Trillium Population Dynamics

Gary Wein started sampling a Trillium recurvatum population at the Meeman Field Station in 1990. Resamplings have occurred in 1991, 1992, 1994, 1999, 2001, 2002, 2004, 2005, 2007. We are examining population structure and dynamics of this perennial, spring emphemeral, to develop a further understanding of its life history characteristics.

Jason Dabbs re-sampled the population in 1999; several other resampling since by myself and Moore.
Disturbance Effects on Old-Field Succession

Beverly Collins and Gary Wein started sampling for this project in 1991. They collected data in 1992, 1993, 1994, and we re-collected the data in 2001. The study examines the effects of disturbance intensity (all vegetation removed vs. only the dominant vegetation removed) and frequency (twice per year, once per year, every two years, every four years) on succession in an old-field; set up a a replicate block design. My graduate student Chad Pope has re-sampled this study for his thesis.
