Whitford, May1983-Sep1985 10) Methods of recording (field data sheets, instrumental, etc.): ------------------------------------------------------------------------- field data sheets 11) 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. 12) 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. 13) Attributes measured: ------------------------------------------------------------------------- Variable Name example: AIRMAX Name used in data set header. Variable Format example: 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 Mask example: mm/dd/yyyy Date where mm=month, dd=day, yyyy=year Exception Value Codes format: [code] = [description] example: 'Q' = questionable data Code = code (surrounded by single quotes) Note: Equal signs (=) are used to separate code and description. Note: Enter multiple Exception Value Codes on separate lines. Acceptable Value Type examples: defined list undefined list range defined list of ranges undefined list of ranges complex external list Acceptable Value Codes format: [code] = [description] example: C = Creosotebush Code = code Note: Equal signs (=) are used to separate code and description. Note: Enter multiple Exception Value Codes on separate lines. Note: Equal signs (=) are used to separate values and commas (,) are used to separate multiple value sets. Ranges of acceptable values are separated by a dashes. Lists of acceptable values are separated by commas. Asterick symbols (*) are reserved to indicate external lookup file listing. ------------------------------------------------------------------------- variable name: YY attribute description: Year data was collected measured units: N/A start column position: 2 variable format: I2 variable mask: N/A exception value codes: N/A acceptable value type: N/A acceptable value codes: N/A variable name: MM attribute description: Month data was collected measured units: N/A start column position: 4 variable format: I2 variable mask: N/A exception value codes: N/A acceptable value type: N/A acceptable value codes: N/A variable name: A attribute description: Plot number measured units: N/A start column position: 7 variable format: I2 variable mask: N/A exception value codes: N/A acceptable value type: range acceptable value codes: 10-18 variable name: B attribute description: Transect number measured units: N/A start column position: 10 variable format: I1 variable mask: N/A exception value codes: N/A acceptable value type: range acceptable value codes: 1-2 variable name: C attribute description: Quadrat number measured units: N/A start column position: 13 variable format: I1 variable mask: N/A exception value codes: N/A acceptable value type: range acceptable value codes: 1-20 variable name: D attribute description: Grasshopper species measured units: N/A start column position: 15 variable format: I2 variable mask: N/A exception value codes: N/A acceptable value type: external list acceptable value codes: See Grasshopper and Substrate/Vegetation Code List (JGRASHOP.LST) variable name: E attribute description: Substrate measured units: N/A start column position: 18 variable format: I2 variable mask: N/A exception value codes: N/A acceptable value type: external list acceptable value codes: See Grasshopper and Substrate/Vegetation Code List (JGRASHOP.LST) variable name: F attribute description: Sex (gender) measured units: N/A start column position: 21 variable format: I1 variable mask: N/A exception value codes: N/A acceptable value type: defined list acceptable value codes: 0 = unknown, usually nymphs 1 = Male 2 = Female variable name: G attribute description: Age measured units: N/A start column position: 23 variable format: I1 variable mask: N/A exception value codes: N/A acceptable value type: defined list acceptable value codes: 1 = early stage nymph 2 = Mid stage nymph 3 = Late stage nymph 4 = Adult 14) 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). 15) Key literature (Citations that describe sampling procedures, [reference of a published paper, thesis, etc.]): ------------------------------------------------------------------------- Lightfoot, D.C. 1985.
