Pill Bugs Lab Report

1275 Words6 Pages

Introduction In nature most organisms cannot change the nature of their environment therefore they must position themselves in an environment with favorable conditions to themselves and their offspring. This behavior is called habitat selection. Many organisms will exhibit a tactic response to these environmental factors. This tactic response can be positive or in favor of a certain environment and negative or against a certain environment.
The purpose of this research was to observe the general behavior characteristics of Pill Bugs (Armadillium vulgare) and design experiments to determine whether Pill Bugs are adapted to sense certain environmental changes and how they respond to those changes or what their tactic response is. The behaviors …show more content…

The Animal Behavior tray was used to create two different habitats for the Pill Bugs to choose from. The watch was used to time the experiment in order to take down data after every minute for ten minutes. The five Pill Bugs were the organisms used to create the habitat selection experiment. The hand lens was used to observe the Pill Bugs closely during the experiment. The two filter papers were used to help keep the behavior tray clean. The pipette was used to put the water into the behavior tray to create the wet environment in the second part of the lab. The water was used to create the wet environment. The procedure for the control part of the experiment starts by taking the Animal Behavior Tray and placing the filter paper in both sides of it. Next take the five Pill Bugs and place them into the behavior tray. Start the timer on the watch and observe the amount of Pill Bugs on each side of the behavior tray and how they are acting. Record this information at the end of every minute for ten minutes, in Table 1. For the second part of the experiment, using the pipette and water, place the water on the filter paper on one side of the behavior tray. Allow the filter paper to absorb the water therefore creating the wet environment. Next, place the Pill Bugs in the behavior tray and observe the amount of …show more content…

At the end of minute one there were four Pill Bugs on Side A and 1 pill bug on Side B and the Pill Bugs were observed to be bunched together. At the end of minute two there were five Pill Bugs on Side A and zero Pill Bugs on Side B. At the end of minute three there were four Pill Bugs on Side A and one pill bug on Side B. At the end of minute four there were three Pill Bugs on Side A and two Pill Bugs on Side B and the Pill Bugs were observed to be active. At the end of minute fivc there was one Pill Bugs on Side A and four Pill Bugs on Side B and the Pill Bugs were observed to be very active. At the end of minute six there was one Pill bug on Side A and four Pill Bugs on Side B. At the end of minute seven there were three Pill Bugs on Side A and two Pill Bugs on Side B. At the end of minute eight there were four Pill Bugs on Side A and one Pill Bugs on Side B. At the end of minute nine there were three Pill Bugs on Side A and two Pill Bugs on Side B and the Pill Bugs were observed to be active. Finally at the end of minute ten there were five Pill Bugs on Side A and zero Pill Bugs on Side B. The wet and dry habitat data was collected second in Table 2. At the end of minute one there were zero billbugs in Side A or the wet side and five Pill Bugs in Side B or the dry side. At the end of minute two there were four Pill Bugs in Side A and one Pill Bugs in Side B. At the end of minute three there were four Pill Bugs in Side A

    Abstract: The main focus of this lab is on animal behaviors in terrestial isopods, also known as pillbugs. There are many purposes to this lab experiment. First, these pillbugs are put into four different types of enviroments, also known as chambers, light v. dark, hot vs. cold, moisture vs. dry, and lastly shelter vs. open. In these different chambers, there are 10 pillbugs, 5 placed into each individual chamber and then observed for up to 5 – 10 minutes. In this lab we observed that pillbugs prefer light areas, hot temperatures, moist environments, and lastly sheltered spaces.

    In the second experiment our hypothesis stated that when the number of males placed in a dish are increased with a (sustained) amount of one female beetle, the time span of the mating process will decrease because the female will have of an option. This hypothesis was not supported because with the trials we preformed the results showed that the different ratio of dishes had a different time span of which they

The hypothesis is to determine if bean beetless oviposition is determined by bean beetle place of birth. I predict the bean beetles will choose their place of oviposition themselves on the mung beans in the petri dish due to their origin. This is a controlled experiment, in which we used independent, and dependent variables.

    Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.

    The overall purpose of this investigation was to determine the effects of different types of environments on pill bug attractancy. Pill bugs were exposed to 2 different environments (sugar and water). The attractancy was observed and recorded in a raw data table. A research hypothesis was formulated that the sugar would work as the best attractant for pill bugs. Sugar had the greatest impact of the two environments used because it attracted 8/9 ants.

    Introduction/Purpose : In this experiment crickets are going to be drugged with two amounts of caffeine. Crickets are omnivores and scavengers that feed on organic materials, as well as decaying plant material, fungi, and seedling plants. They are usually medium-sized to large insects, and known to be relatives and/or look alike to a grasshopper. Crickets can live for a year or more, but usually can't survive more than one winter.

    A Demonstration of Chemotaxis Between Flies and Various Substances (Sugar vs Bacteria) Abstract: The purpose of this lab based on the Drosophila melanogaster (the common fruit fly) reactions. Since the fly has been studied and observed for many years, and known for its unique chemotactic attractions to different stimuli, it was an ideal organism for the study being conducted. In the experiment the purpose was to be able to figure out whether the flies would be more attracted to sugar or bacteria.

  • Isopods Vs Pillbugs

    1003 Words  | 5 Pages

    In this experiment, we are testing whether or not the Isopods' have more of a preference for an environment with syrup or with water. The alternative hypothesis we devised is that if the Isopods are placed in between a syrup and a water chamber, then they will go towards the syrup chamber. This is believed because we believe the Isopods may have an attraction to the sweet scent and taste of the syrup. My group and I observed 10 pillbugs behavior over the span of 5 minutes, recording the number of pill bugs found in each chamber every 30 seconds. We fail to reject the null hypothesis because the chi squared value is 3.6 which is less than 3.84 (critical value at .05).

  • Examples Of Exploratory Behaviour

    Exploratory behaviour can be defined as “activity in an unfamiliar environment” (Sih et al., 2004) Such behaviour occurs either when entering a new environment or being introduced to a novel object. This behaviour stops once the animal becomes familiar with its environment ( Shillito, 1963). Exploratory behaviour has an effect on fitness. Male zebra finches that exhibit more exploratory behaviour, have more breeding attempts and nestlings.

    Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.

    Imagine what would happen if we lived in a world where water was kept 8 feet off the ground and there was absolutely no way you could get it if you weren’t tall enough. Most likely, the short people would die off. The taller ones would multiply, and before long, instead of a population of people of all sizes, you would have a population of only tall people. Living things that are best suited, or adapted, to their environment survive and multiply. Those that are not, are unable to survive.
