Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
We created traps consisting of illumated oil-filled trays of 5 different colors that variously horizontally polarized light from ~20% to ~100%. These were placed in a row 5, 10 and 15 meters from 5 different rivers in southern New York State. They were exposed for 2 hours before sunset and their location randomized every 20 minutes. The goal of the study was to map the behavioral reaction norms of a diversity of aquatic insects to variation in the degree of polarized light and to understand how those reaction norms shifted as a function of the distance between a high quality natural habitat and the ecological trap habitat the test surfaces represented. Metadata for the variables is provided.
