Summary

Short name: 

LUQMetadata43

Data set ID: 

43

Abstract: 

The data set consists of counts of terrestrial invertebrates from the grid at Bisley Watersheds #1 and 2, for the years 1989, 1990, 1994, and 1999. Data for 1989 and 1990 are confined to 4 species of terrestrial snails: Caracolus caracolla, Gaeotis nigrolineata, Nenia tridens, and Polydontes acutangula. Counts for other snail species and the walking stick Lamponius portoricensis are available for 1994 and 1999.

Methodology

Methods: 

Thirty six points were selected from the grid at Bisley based upon accessibility during night-time surveys (for a map of the study plots, see Willig and Camilo, 1991). See the List of Codes of the 36 selected grid points. Circular quadrats (r = 5 m) were established at each point and sampled during the wet season immediately prior to Hurricane Hugo (June-August 1989), that immediately following Hugo (July-August 1990), and in July-August of 1994 and August of 1999. Sampling at each of the selected points consisted of a minimum of two individuals searching all available surfaces within a quadrat (e.g., vegetation, litter, rock, soil) for the presence of snails. All surveys occurred between 19:30 and 03:00 hours to coincide with peak snail activity.
