+------------------------------------------------------------------+ | JORNADA LTER | | New Mexico State University | | Data Set Documentation Form | +------------------------------------------------------------------+ All Jornada Desert Site NSF/LTER data sets must be documented on the following form. This applies to any data set intended for permanent archiving. All raw data sets collected under the auspices of the Jornada NSF/LTER Program will be described by the following standardized form. Information that is not available at this time, must be included when available. See data manager for any questions regarding this form. -------------------------------------------------------------------- 1) Data set title: --------------- Jornada Grasshopper 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): -------------------------------------------------------- September 1985 (09/1985) 6) Expected duration of study: --------------------------- 3 years (May 1983 - Sep 1985) 7) Frequency of measurement: ------------------------- May, July, September: 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): ---------------------------------------------------------------- This is grasshopper data sampled from 9 plots on the east bajada of the Dona Ana Mts. Three plots were situated on the bajada parallel to and 200 m south of the LTER-I transect. Two additional sets of three plots were located 5 km and 10 km south of the LTER transect. Each plot is composed of two 50 m belt transects, each divided into ten 5 m2 quadrats. 11) Data set description (State the hypothesis and / or objectives which collection of data set addresses): ---------------------------------------------------------------- This is grasshopper data sampled from 9 plots on the east bajada of the Dona Ana Mts. Three plots were situated on the bajada parallel to and 200 m south of the LTER transect. Two additional sets of three plots were located 5 km and 10 km south of the LTER transect. Each plot is composed of two 50 m belt transects, each divided into ten 5 m2 quadrats. Grasshoppers were visually sampled in each quadrat/plot, once in May, July and September, in 1983, 1984 and 1985. Each individual grasshopper, its age, sex and substrate it was observed on, are 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. [#.##]) Variable code: * See attribute description listing See external listing of variable codes N/A = Not applicable VARIABLE MEASURED VARIABLE NAME FORMAT UNITS CODE ATTRIBUTE DESCRIPTION -------- -------- -------- -------- ------------------------- YY I2 N/A N/A Year data was collected MM I2 N/A N/A Month data was collected A I2 N/A 10-18 Plot number B I1 N/A 1-2 Transect number C I1 N/A 1-20 Quadrat number D I2 N/A * Grasshopper species E I2 N/A * Substrate F I1 N/A 0 Sex: unknown, usually nymphs 1 Male 2 Female G I1 N/A 1 Age: early stage nymph 2 Mid stage nymph 3 Late stage nymph 4 Adult * See Grasshopper and Substrate/Vegetation Code List 13) Methodology (Provide sufficient detail such that an unaware reader could repeat the described data collection procedures.) ---------------------------------------------------------------- Enter each quadrat, search for grasshoppers, visually identify each grasshopper to species, estimate nymphal instars, record sex, and substrate individuals are observed on (e.g. plant species if on vegetation, soil type if on ground). 14) Key literature (Citations that describe sampling procedures, [reference of a published paper, thesis, etc.]): ---------------------------------------------------------------- Lightfoot, D.C. 1985. Substrate utilization and guild structure in desert grasshopper assemblages. Master of Science, New Mexico State University, Las Cruces, NM. 15) Keywords (keywords that describe data set; maximum of 10): ---------------------------------------------------------------- grasshoppers, seasonal patterns, annual patterns, spatial patterns, assembly structure, population dynamics, habitat, substrates 16) Treatment of data: (List any programs used in analysis of the data): [Note: Programs should be appended and stored with this form.] ---------------------------------------------------------------- 17) Associated computer accounts: ---------------------------------------------------------------- 18) Files associated with this data set: ---------------------------------------------------------------- A) Metadata files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- JGRASHOP.PRJ Project documentation JGRASHOP.DSD Data set documentation ------------ ----------------------------------------------- B) Data files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- JGRASHOP.DAT Data file for 1983 - 1985 ------------ ----------------------------------------------- C) Data entry, verification, and analysis files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- GHJ83.DAT Data file for 1983 GHJ84.DAT Data file for 1984 GHJ85.DAT Data file for 1985 ------------ ----------------------------------------------- D) Other (Any other related files.)
