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

    Armadillidium Vulgare Experiment

    The purpose of the lab was to observe the environmental impact on the behavior of pill bugs (Armadillidium vulgare) by using the steps of the scientific method. . We placed two pill bugs in an enclosed space and recorded the amount of time they spent in two categories of living spaces: hard rocks or soft sphagnum moss. Despite predicting that they would have a preference for a softer area, both pill bugs spent more of their time in the rocks than in the moss. This suggests that Armadillidium vulgare has a preference towards environments with hard surfaces over soft ones, possibly due to factors like light or surface area. However, certain experimental errors such as material density and poor handling may have skewed the accuracy of results.…

    Environmental Effects on Pillbug Behavior Catherine Liapes October 14, 2015 AP Biology- Pd.9 Mr. Angus Introduction: Before conducting this lab, I researched information on pillbugs and learned that pill bugs are commonly found in damp environments such as piles of leaves, or under logs. Although they are crustaceous, they can still spend their entire lives on land. They are about ¾ inch in length with seven pairs of legs, and multiple antennae. Pillbugs are nocturnal and mainly consume rotting vegetation.…

    The termites followed the lines because of the chemicals that were in the Pentel Pen. Moreover, termites will follow mostly any straight or rounded line that is drawn by some pens. Lastly, if this experiment was repeated with the same sharp angled line and a more rounded angled line, the termites will most likely follow the more rounded angled line. Thus a new hypothesis can be made that states that termites will follow lines that mostly don't have sharp…

The Green Crab is native to Europe but at time went by it spread to America,australia and is at risk of spreading all over the world. The spread of Green Crabs was most likely by natural dispersal in the oceanic currents,or by domestic dispersal mechanisms. Also Green Crabs can tolerate a wide range of environmental extremes such as cold temperatures, low salinities, etc ,which means controlling their population is very difficult. The invasion of green crabs has huge impact on the ecosystem as they are carnivore, who eat Oysters,clams and hundreds of other Species.…

    Pill Bug Lab Report

    Isopods that live on land are called Armadillidium Vulgare, also known as pill bugs. Pill bugs consume dead organisms in decomposing soil which are acidic in nature. This trait makes these organisms beneficial to our environment, by getting rid of all the dead and decomposing organisms. Pesticides are commonly used to deter pests from eating crops, and could be getting rid of beneficial organisms such as pill bugs instead. An experiment was performed to determine the preference of pill bugs in choosing between an acidic environment as opposed to basic environment.…

    The data shows that once the round goby was introduced to the ecosystem the native species began to decline. The four native species in lab were perch, bass, bluegill, and walleye. Each species had to use a different utensil to collect food. The perch used one plastic spoon, the bass used two knives, the bluegill used one fork, and the walleye used two forks. In graph one it is shown that the smallmouth bass still survived greatly even with the round goby in the ecosystem.…

    Parasitoid Beetles

    Biological control involved using known predators, parasitoids and pathogens of the powder-post beetles. Predators kill and consume their host immediately, whereas parasitoids lay their eggs inside the host that will slowly be eaten internally by the growing larvae. For Dinoderus minutus, known predators include Teretriosoma nigrescens (Coleoptera: Histeridae) that has also been reported to successfully suppressed other stored-product pests (Pöschko, 1994). The braconid wasp, Doryctus jarbus (Hymenoptera: Braconidae) was reported as parasitoid of eggs and larvae of D. minutus. Several species of chalcid wasps (Hymenoptera: Chalcididae) were listed parasitizing Sinoxylon anale (Gumovsky, 2010).…

    Ground Beetles

    One of the most intimidating tasks challenging an aspiring entomologist is the identification of species within a family as diverse as ground beetles (Choate, 2001). Ground beetles are one of the most diverse insect families in the word. They occur in apparently all terrestrial habitats and represent a major part of the invertebrate predator guild of the soil fauna, e.g. in forests, maquis and agrocoenoses (Arndt et al., 2011). Ground beetles are often chosen for study because they are abundant in most terrestrial habitats, diverse, taxonomically well known, serve as sensitive bioindicators of habitat change, easy to capture. Through a series of taxon pulses, they have radiated to drier environments as well as higher latitudes and altitudes…

    Argument Against Psychological Egoism

    In this paper, I will argue that people who should be considered to be altruistic are those who act magnanimously to those outside of their family or general social group. I will use examples such as kin selection, animal altruism, and arguments against psychological egoism to assist in proving my thesis to be true. I will also address a counter argument made by some psychological egoists who believe that due to most people feeling pleasure while doing good things for others, that there are no people only act selfishly. I will reference James Rachel ’s essay “Psychological Egoism” to help enhance my theory that not all acts must be out of self interest.…
