Pillbug Lab Report

Once acclimated, the isopods walked around the arena for five minutes and go to the sponges that they preferred. The experiments should be repeated 3 times with the same design layout for accurate results. 20 isopods were released in the center of the arena. After five minutes, the number of isopods behind every sponge was

Pill bugs (Rollie Pollie): The Effect of Isopod Behavior on Wet vs Dry Stimuli Abstract: There are two main purposes for this experiment. First, isopods were observed so that their behavior could be recorded. Second, we exposed the isopods to a wet cotton ball and dry cotton ball, to determine which stimuli the pill bugs (or Rollie pollies) preferred over the other.

The effects of where these larvae are laid can dictate the fate of these gall fly larvae. A study shows that avian predators can assess a gall 's content prior to pecking it open, preferring galls that are inhabited by gall fly larvae. Bird predation was found to be concentrated near the places with a lot of tree cover where S. gigantean a large centipede tends to pray few attacks occurred in the open where golden rods are prevalent. The study was a field experiment to observe the preference of avian predators on galls in different habitat types and that had different sizes, and heights of galls. It is possible that birds have either learned through experience or evolved through natural selection to choose the more profitable galls (Poff et al. 2002).

Pill bugs and sow bugs are similar names that been give for land isopod. They are crustaceans in the order of Isopoda that are usually found in both terrestrial and aquatic, even though many isopods are found mainly in aquatic, only pill bug and sow bug are found exclusive in the land. Pill and sow bugs are been classify as arthropod phylum of Arthropoda. The body of a pill or sow bug consists of three main parts which are head, thorax and abdomen. The head contains two antennae and mouth parts.

When they are communicating with one another they likely use chemicals. Now some abiotic resources that would exist in your given ecosystem would be humidity, amount of rain, amount of sunlight, and the temperature. Biotic factors would be different types of trees and plants, other bugs, animals, and even humans. One way that we benefit from the pillbug is that they can serve as a form of biological weed control. Now to your final question Pillbug’s are r strategist and have many young, though within the first few days of hatching less than half of them live and only a handful make it to adulthood.

Nicholas Hack-Irvin Bio 104-06 October 25, 2015 Earthworm Response to Spicebush Methods: Using a plastic container lined with wax paper, two pieces of construction paper were cut to each fit the width of the box. These two pieces of construction paper were placed in close proximity to each other to ensure that both sensory feedbacks would be noticeable to the earthworm when placed in between the two pieces of paper. One strip of paper was lightly covered in water, where the other piece of paper was lightly covered in spicebush extract. 10 replications were performed where a different worm was placed in the center of the container each time, equidistant from both pieces of construction paper, and observed to see whether it would move towards

Each ecosystem has their own biodiversity, differing themselves from other ecosystems. In our experiment we are revisiting how the intensity of light effects the movements of Gammarus setosus. From J. M. WeEsøawski, M. ZajaÎczkowski, J. Wiktor (1997) report, when there are Macrofauna taxa and Macrophytes, there would a frequent amount of Gammarus setosus. With this we can conclude that Gammarus setosus plays a large role in the food chain. By getting more information of the Gammarus setosus we able to get more information for future research into the how prey and predation with the Gammarus setosus.

For hundreds of years, ladybugs have been greatly appreciated by farmers. Ladybugs will feed on the crop-damaging insects such as caterpillars, and, essentially, save the crops. Unfortunately, many of the farmers that work in colder climates cannot use ladybugs to keep their crops alive because the insects live only in warmer climates. Thankfully for them, there are some organic pesticides that keep the ladybugs alive, even in cold climates! These pesticides allow ladybugs to eat all of the insects that farmers don’t enjoy having around.

Alina Swanson Period 2 Mrs. Broad September 30, 2016 Isopod Lab Introduction: This lab is used to see if and how many of the Isopods like the light or the dark. Isopods also known as pill-bugs, roll into a ball when felt threatened. Isopods are very similar in body types as lobster, crabs, and shrimp. They all have compound eyes and antennae, but still sometimes do not always look alike.

They have stylets which allow them to pierce plant cells and animal body walls. They have a sucking pharyngeal bulb which allows them to ingest food. They are also known to eat entire live organisms. Female Tardigrades will lay 1-30 eggs at a time, and these eggs are light enough to be carried by other animals for great distances, spreading the population. Fertilization can occur through a gonopore or the male can deposit his sperm on the eggs after they have been laid.

The female will build her nest using grass, bark, hair and spider webs. If for some reason

Not only do beautiful places exist in the fairy tales, but also in the real world. Travelling offers the opportunity to see the beauty of nature. We are constantly dreaming about our next trip and as a consequence of our permanent desire of travelling we search the Internet in order to find exciting destinations. As I have searched the Internet during the past few weeks I have discovered with astonishment many natural places which are beyond my wildest dreams.

Did you know that the ladybug’s name is actually the ladybird? “They are called ladybirds because they can fly like birds”. www.factslist.net says. Its name originated from Britain, where the insects became known as “Our Lady’s bird” or the “Lady beetle”. Mary (Our Lady) was often depicted wearing a red cloak in early paintings and the spots of the seven spot ladybird were said to symbolise her seven joys and seven sorrows.

The traits that all arthropods share are bilateral symmetry, body segmentation (head, thorax, abdomen), an exoskeleton made up of articulated plates, articulated appendages, growth via molting, a pair of compound eyes and an open circulatory system featuring a dorsal heart with lateral valves (Grimaldi and Engel 2005). The Arthropods (especially the insects) were able to adapt to survive in their new environment, so well they became the most successful and abundant group compared to the others under animalia. Insects, as a member of the phylum arthropoda, possessed an exoskeleton, which supported them. Additionally, terrestrial arthropods generally adopt a more stable hanging stance, standing on the underside of their limbs whose ends are at a low angle to the ground (Stormer 1970). Both characteristics allowed them to move quite easily on land.

Introduction Among all the animals living on earth, insects are the most diverse. They are found in all habitats such as deserts, forests, swamps and even the pools of crude petroleum (Imms, 1964).The number of insects exceeds all other animals and this due to the undeniable fact that they are able to adapt themselves to any kind of environment. The evolution of flight in insect is regarded as the significant breakthrough in the history of Earth. They were the first to dominate the air even before other terrestrial animals and also the time taken for diversification go beyond other organisms which all together lead to their dominance across the planet. Most of the insects are considered important to human beings and the environment as they
