Each trap is 40 cm deep and contains an inner plastic container and funnel. A ceramic tile is placed over each trap. For a 2-week period each month, from 16 June 1989 to 23 August 1991, the tiles were raised on one side, and the traps are checked every 3 days in summer and once a week in winter. For the period post-August 1991, the traps are opened for 2 consecutive weeks on a quarterly basis (Feb, May, Aug, Oct). The arthropods in the inner containers are all combined to one container for each plot, brought to the lab, preserved, and sorted to taxa. Non-ground dwelling arthropods are released in the field. Large long-lived arthropods such as tarantulas are recorded and released in the field. See PITFALL.PRO file for detailed protocol. 16) Key literature (Citations that describe sampling procedures, [reference of a published paper, thesis, etc.]): ---------------------------------------------------------------- 17) Keywords (keywords that describe data set; maximum of 10): ---------------------------------------------------------------- arthropods, pitfall traps, consumers, populations 18) Treatment of data: (List any programs used in analysis of the data): [Note: Programs should be appended and stored with this form.] ---------------------------------------------------------------- Data is entered from field data sheets using LOTUS 123 add-in called D.A.V.E. which is a data entry and verification program. 19) Associated computer accounts: ---------------------------------------------------------------- 20) Files associated with this data set: ---------------------------------------------------------------- A) Metadata files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- PITFALL.PRJ Project documentation PITFALL.PRO Pitfall trapping procedures ARTHPIT2.DSD Data set documentation ------------ ----------------------------------------------- B) Data files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- ARTHPIT2.DAT Data file ARTHPIT2.HIS Data set history log ------------ ----------------------------------------------- C) Data entry, verification, and analysis files FILE NAME DESCRIPTION OF FILES ------------ ----------------------------------------------- ARTHRPIT.IMG Data entry template image used to enter data using LOTUS add-in D.A.V.E.
