Title

Canopy Trimming Experiment (CTE) Snail data
Summary

Short name: 

LUQMetadata152

Data set ID: 

152

Abstract: 

The objective of these data is to determine how green litter deposition and canopy opening associated with a hurricane independently and jointly affect population dynamics and community composition of terrestrial gastropods. Because canopy openness can be expected to increase abiotic stress on gastropods, whereas litter deposition should provide increased resources and refugia, tradeoffs can be expected.

Methodology

Methods: 

Plots were sampled during two time periods each year:  March (“Dry” season) and July or August (“Wet” season).  During each sampling period, there were 3-4 nocturnal surveys of each CTE plot.  Researchers were randomly assigned to subplots within each plot.  Each time a subplot was sampled, the surveyor spent 15 minutes searching all exposed surfaces (e.g., vegetation, rocks, leaf litter, soil surface) within the boundary of the subplot for snails and slugs.  All surveyors were instructed to minimize trampling damage to the plots by using walkways whenever possible, to avoid at all costs stepping in the seedling plots, and to avoid disturbing the plots by sifting through leaf litter, turning over rocks or dead wood, etc.  Snails and slugs were identified to species but, whenever possible, not removed from their substrate.  Block A was not sampled in March of 2005 because the experimental treatments were underway.
