Method, pan trap data set: This experiment was conducted with Setareh Rezvani on a slightly rainy day with a climate of 16° at the grasslands and woodlots area at Saywell Woods at York University on Monday September 25, 2016 at approximately 3:00 PM. 20 solo bowls were obtained, 10 of which were white, and the remaining 10 were blue. 5 blue bowls and 5 white bowls were placed in the grassland; the white bowls were placed near areas with many flowers whereas the blue bowls were placed in areas with just grass. 5 blue bowls and 5 white bowls were placed in the woodlot; the white bowls were placed near the trees whereas the blue bowls were placed away from the trees. All 20 solo bowls were filled with soapy water and were left for approximately 2.5 hours. After 2.5 hours subsided, the number of animals and the number of rtus (recognizable taxonomic units) were obtained for each bowl. 

Metadata:

Colour of bowl is a categorical variable that provides the different colour solo bowls used in the experiment. The solo bowls were blue and white.

RTUs (recognizable taxonomic units) is a continuous variable that provides the different types of insects found in each sample.

# of insects is a continuous variable that provides the total number of insects found in each sample.

Hypothesis: There will be a higher abundance and diversity of animals found in the grasslands than woodlots because there are more flowering plants in the grasslots, where more animals reside and some animals are more attracted to because of pollination.

Prediction: The most number of animals and rtus will be found in the white bowls in the grassland because they are located nearest to the flowering plants.  The second highest number of animals and rtus will be found in the blue bowls in the grassland because the flowering plants are still somewhat nearby and insects still reside in the general area. The least number of animals and rtus will be found in the blue bowls in the woodlots because they are located away from the trees and there are fewer flowering plants in the woodlots.
