See data manager for any questions regarding this form. -------------------------------------------------------------------- 1) Data set title: --------------- Jornada grasshopper plot herbaceous vegetation data 2) Project title: -------------- Jornada Grasshopper and Vegetation Study 3) Responsible investigator(s): ---------------------------- David Lightfoot 4) Date data collection commenced (mm/dd/yyyy): -------------------------------------------- May 1983 (05/1983) 5) Date data collection terminated (mm/dd/yyyy or ONGOING): -------------------------------------------------------- Sep 1985 (09/1985) 6) Expected duration of study: --------------------------- 2.4 years (May 1983 - Sep 1985) 7) Frequency of measurement: ------------------------- May, July, September from 1983-1985 8) Researchers: (Personnel who will be obtaining data and who would need to be contacted directly if there is a problem in the raw data): ---------------------------------------------------------------- David Lightfoot, Walter G. Whitford 9) Methods of recording (field data sheets, instrumental, etc.): ---------------------------------------------------------------- field data sheets 10) Site location (Describe in sufficient detail that the site can be relocated): ---------------------------------------------------------------- 11) Data set description (State the hypothesis and / or objectives which collection of data set addresses): ---------------------------------------------------------------- This is data on annual herbaceous plants measured on Jornada grasshopper plots on the east bajada of the Dona Ana Mts. Three plots were situated on the bajada parallel to and 200m south of the LTER transect. Two additional sets of three plots were located 5km and 10km south of the LTER transect. Each plot was composed of two 50m belt transects, each divided into ten 5m2 quadrats. Annual plants were measured in the NE 1m2 of each quadrat, once in May, July and September in 1983, 1984 and 1985. All individuals of each species were counted and measured. A mean diameter, height, and the total number of individuals/1m2/quadrat were recorded. 12) Attributes measured: ------------------------------------------------------------------- Variable name: blank Number of columns between fields CCCCCCCC See attribute description Format: C = character (C3: Three characters [XXX]) I = integer (I2: Integer with two places [##]) F = floating point (F4.2: Total places with decimal point = 4, with 2 decimal places.
