Discussion: The techniques used in this experiment are very useful for an efficient assessment of the quality of the habitat with regards to scavenging. This experiment is not costly with experimental apparatus and design. The high cost of achieving these consistent results is effort and time. The experimental set up required many participants to carry out the procedure however since each area was only studied for 40 min this is a relatively rapid assessment. The most dominant ant scavenger was found to be the Yellow Crazy Ant. A possible contributing factor of the success of the Yellow Crazy Ant is anthropogenic habitat change, by causing changes in species interactions [3]. Kent Ridge and Singapore in general has undergone much anthropogenic …show more content…
(Habitat), Yellow Crazy Ants arrived at 13 out of 37 of the areas tested. Yellow Crazy Ants arrived at 5 of the forest locations, 3 of the grassland and 5 of the impervious. The average time for first ant to arrive at the forest habitat was 257.0833 seconds, grassland was 113.3077 seconds and impervious was 141.4167 seconds. The most dominant ant species for question 1 was Crematogaster sp. (Valentine ant). Crematogaster was most dominant at 9 locations. Yellow Crazy Ant was most dominant at 6 locations. Tapinoma melanocephalum (Ghost ant) was most dominant at 5 locations, Oecophylla smaragdina (Red weaver ant or Kerangga ant) was most dominant at 5 locations, Pheidole was most dominant at 4 locations, Dolichoderus was most dominant at 3 locations, Camponotus chromaiodes (Carpenter ant) was most dominant at 3 locations and Paratrechina longicornis (Black Crazy ant) was most dominant at 2 locations. Impervious habitat was found to be the most species rich habitat. Impervious habitat had an average of 3.25 species while Grassland had an average of 3 and Forest had an average of 2.666667. At 40 min an average of 42.83784 ants arrived at each area. Grassland had the highest amounts of ants arrived and forest had the lowest (Figure 2). Ants arrived quickest at grassland then impervious, then finally forest (Figure …show more content…
(Natural vs Artificial) Yellow Crazy Ants arrived at 13 of the 45 areas tested. All 13 were in forest habitat. The average time for an ant to arrive at forest artificial bait was 311.2727 seconds. The average time for an ant to arrive at forest natural bait was 597 seconds. The average time for an ant to arrive at impervious artificial bait was 210 seconds. The average time for an ant to arrive at impervious natural bait was 450 seconds. Artificial bait attracted ants faster than natural bait (Figure 1). Forest habitat, artificial bait had a species richness of 1.818182 species. Forest habitat, natural bait had a species richness of 1.909091 species. Impervious habitat, artificial bait had a species richness of 2.08333 species. Impervious habitat, natural bait had a species richness of 2 species. The most dominant species was Yellow Crazy Ant. At 40 mins an average of 50.04348 ants arrived at each area. Impervious habitat had a larger number of ants arrived than forest habitat. For impervious habitat the natural bait attracted more ants than the artificial bait (Figure
