Abstract A two-part study was recently done to show what natural habitat a Pill bug‚ Armadillidium vulgare‚ naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment‚ a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light

Allison Jones Dr. McNelis AP Biology--Class 6 2013 September 4 Introduction The study of animal behavior is ethology. There are two basic categories of animal behavior: learned behavior and innate‚ or inherited‚ behavior. Learned behavior is when animals acquire knowledge about their behavior through experience. Unlike learned behaviors‚ innate behavior exists naturally in animals‚ meaning that animals are born with some behaviors. In order to find a suitable environment‚ animals use orientation

There are many interesting facts about the pill bug. The pill bug is also known as sowbugs‚ woodlice‚ or by their scientific name Armadillidiidae vulgare . Some of their physical characteristics include a hard black‚ brown‚ or gray shell (depending on the species being studied)‚ sharply angled antennae‚ seven pairs of legs‚ flattened or round-backed profile and an oval shape. Their head has 4 pairs of mouthparts and is followed by the 7 main trunk segments‚ which bear the walking limbs. Pill bugs

Animal Behavior: Response to Environmental Variables Background/Abstract: Ethology is the science based on animal behavior. Many animal behaviors involve the movement of animals within its own environment. Inherited traits are traits that an animal is born with and learned behaviors are what an animal learns on its own to adapt to the surroundings. Innate behaviors like breathing and learned behaviors are talking or walking. Pill bugs are the animals we observed in the lab. Pill bugs are a family

The objective of our experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms

Introduction These species are commonly known as pill bugs; they are terrestrial crustaceans that are oval shaped and a little flat. Pill bugs live in gardens‚ fields‚ forests or any region that is moist and are most likely found under rocks. The reason behind as to why isopods prefer a moist area is because they don’t have a good waterproofing cuticle wax‚ which causes them to dry out easily (“Critter Catalog‚" n.d.‚ para. 8). Pill bugs are also known as “roly-polies” because of their ability to

Donesha Foster Lab Report Dr. Arrigo-Nelson Bio 120 - 1A Isopod Habitat Preference INTRODUCTION Isopods are found in different types of habitats‚ from freshwater or marine to deserts and in damp‚ cool areas. Pill bugs are slow-moving‚ crawling creatures‚ and they are cold-blooded‚ which means their body temperature is regulated by the surrounding environment (Grzimek). Like other invertebrates‚ pillbugs are ectothermic‚ meaning their body temperature varies with the environment (Pillbug Profile)

The Rolling Choice A pillbug also known as a roly-poly is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil‚ under rocks‚ and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows it sheds its old exoskeleton 4 to 5 times. A pillbug consists of three basic body parts‚ the head‚ thorax‚ and the abdomen. Pillbugs eat decaying plants and animals as well as some living plants. The purpose of this

For the first part of the experiment we found that four of the five pill bugs found their way to the leafy environment. However‚ most of their time was spent in the section of soil. For the second part of the experiment where we tested each of the pill bugs separately‚ we found that the bugs spent most or all of their time in the soil environment‚ therefore‚ composing the answer to the question of their most favored environment. The chart in image two contains the data found in the first part

Pill bugs are knows as woodlice‚sowbugs‚ and roly-polies.Despite the name Pill bugs aren’t actually “bugs” they are classified as terrestrial isopods and fall under the class Crustacea.This class also falls under an even larger group called Arthropoda. Arthropoda consists of many Arthropods that have bilateral symmetry‚segmented bodies‚exoskeletons‚jointed appendages‚and numerous pairs of limbs.Pill bugs also have a flattened or round-backed profile‚seven pairs of legs‚ and sharply-angled antennae
