Title: Accumulated data of E123, Biodiversity I - Effects of plant biodiversity on population and ecosystem processes Principal investigators: David Tilman, Peter Reich, Johannes Knops, David Wedin LTER: Cedar Creek Natural History Area Data set: treatment data Project: E123 Year: 1995-2001 Date: March 2002 General notes: Rudbeckia hirta and Rudbeckia serotina are the same species Percent cover notes: 1996: Month 6 - Calculations of total percent cover have been modified from then dataset created in 2001. Previous calculations had inadvertently incorporated mosses & lichens into the total cover. The new calculation does not incorporate the category; SR and EtoH have also been modified accordingly. Month 7 - Bird nest was changed to bare ground; month 8 - Dist. ant hill was changed to Disturbance; The cover of two quadrats in each plot were recorded by species while two quadrats were recorded using only the categories bare ground and miscellaneous species. 1998: Quadrats BX in Plots 18, 34, 52, 57, 83 did not add to 100 Quadrats GX in Plots 2, 18, 27, 33, 52 did not add to 100 Adjustments were made in these quadrats to achieve a total of 100% 1999: Quadrat BX is missing for plots 14, 27, 28, and 98. Aboveground biomass notes: 1997: Sample size = 0.20 m2 1998: Sample size = 2 X 0.20 m2 1999: Sample size = 2 X 0.20 m2 2000: Mean of 2 strips, each with sample size = 0.20 m2 2001: Sample size = 2 X 0.30 m2 Root biomass notes: 1996: Sample size = 3 cores, 5.08 cm diameter, 0-30cm depth 1997: Sample size = 3 cores, 5.08 cm diameter, 0-30cm depth 1998: Sample size = 6 cores, 5.08 cm diameter, 0-30cm depth 2000: Sample size = 6 cores, 5.08 cm diameter, 0-30cm depth 2001: Sample size = 6 cores, 5.08 cm diameter, 0-30cm depth Chemistry notes: 1998: Moisture for Plot 18 0-20 and also for plot 51 40-60, which was anomalous, was estimated from the average moisture for the other plots, as follows: Observations: 292 Mean: 5.458116 Standard deviation: 0.656014 Minimum: 3.89 Maximum: 7.21 Light notes: 1999: The second average light readings were taken at a different time of day than the first average light readings. The first readings were taken by a team who started from the lower numbered plots. The second readings were taken by another team who started, at the same time, from the highest numbered plots. 2000: Light readings for some plots were taken twice.
