Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

Lap Report: Pill Bugs Abstract The sow bug‚ also called the pill bug‚ is an isopod that does not have a wide range of items that it likes to eat. In the experiment we were trying to see how the pill bug reacted with certain man made substances and two substances that they would find in their everyday habitat. We tested ketchup‚ orange juice‚ sand‚ baking soda‚ flour and water. The pill bugs did not like the ketchup and orange juice I believe because of the strong acidic smell and it didn’t

Problem: Do Pill bugs prefer being in an environment with tight spaces‚ or a more open environment? Hypothesis: If the pill bugs are given a choice of an open environment or one with tight spaces‚ then the pill bugs will respond by going to the environment with tight spaces. Brief Methods We used a Petri dish with 2 circle‚ and an opening connecting the two. We put 10 Pill Bugs in the opening between the two circles‚ and timed them for one minute. This gave them time to choose dish 1 or dish

OUTLINE. Introduction to the Question: -A subclass of pheromones is necromones‚ which contain oleic acid as a primary component. -Some pheromones trigger aggregation between organisms‚ others can trigger separation. -Necromones trigger necrophoric (organisms remove their dead) or necrophobic (organisms avoid their dead) behavior. -Arthropods use pheromones‚ this includes sowbugs and cockroaches. Chemical signals are picked up by antennae. II. Hypothesis: When given a choice between two identical

* Biology Investigation 3.1 Porcellio Scaber (Slater‚ Woodlouse) Task 1 The crustacean Porcellio Scaber‚ or more commonly known as the woodlouse‚ is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type‚ and is generally predated on by small mammals‚ lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface

mainly due to woodlouse’s inefficient water-storage system. A woodlouse‚ if exposed to heat or light for too long‚ can die due to the dramatic loss of water. They prefer a moderate temperature‚ because they are so small‚ and can be damaged by frost if they are exposed to the extreme of cold‚ but they don’t want such a high temperature‚ either‚ because they would start loosing too much water. I would also expect the woodlouse to prefer a surrounding of slightly higher pressure (1.05 ~

Woodlice Investigation Introduction: The ecological niche of the woodlice Porcellio scaber. The woodlouse Porcellio scaber is native to Europe but also commonly found in New Zealand. They live in cool‚ dark‚ damp microhabitats such as in rotting wood‚ under rocks‚ in caves and leaf litter. Small insectivorous rodents and birds as well as some spiders feed on woodlice. In the rotting log from which I gathered my specimens there were also millipedes‚ crickets‚ weta and spiders living. Woodlice

their speed. We hypothesized that the bigger woodlice have higher speed than smaller woodlice. We conducted an in-class experiment to test our hypothesis. We took ten woodlice and divided them into two groups: smaller and bigger woodlice. Each woodlouse was then let to run for 10 cm and time taken to reach the destination was recorded. Finally‚ when all woodlice completed running‚ we conducted a t-test. The value of ‘P’ from our test was 0.8956 which is larger than 5% level of significance. Since
