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

Variables: Variable How can it be controlled? (IV) - Light intensity - The light intensity will be controlled by the knob on the lamp throughout the experiment. In addition‚ the light intensity will be controlled by closing the windows and doors in the classroom as well as turning

have a structure shown in figure 1. Porcellio scaber contain two pairs of antennae although second pair is extremely small in size and well hidden‚ and two compound eyes (consist of thousands of individual photoreceptor units or ommatidia) (2). Male woodlice have genital projections whereas females just have a pouch which contains eggs‚ positioned at the bottom of the abdomen. Figure 2 shows an example of the ventral (lower) structure of a male Porcellio scaber. As you can see the lungs are situated

abundance they provide good material for an ecological investigation into their preferred habitat. Woodlice are of the order Isopoda which means‚ "The legs are alike". Different species prefer different dwellings however the Common Rough Woodlouse (Porcellio scaber)‚ which has been used for this investigation‚ is commonly found around residential properties. They can be found under rocks or around compost heaps where the soil is moist and a humid atmosphere is maintained. One abiotic factor that affects

* 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

Woodlice - Porcellio Scaber Research: Introduction: [The following is summarised from: http://soilbugs.massey.ac.nz/isopoda.php] Common Names: Slaters‚ pill bugs‚ sow bugs‚ woodlice‚ Maori papapa Scientific Name: Arthropoda (Phylum) Crustacea (Class) Isopoda (Order) Oniscoidea (Suborder). Description: Slaters are apart of the Isopoda order‚ meaning they have an equal number of legs. They are also a crustacean‚ but unlike most crustaceans they are terrestrial opposed to marine dwellers

placed in a cool dark area (for example‚ the veggie section of the refrigerator). http://soilbugs.massey.ac.nz/isopoda.php (19/03/15) Woodlice are one of the easiest terrestrial arthropods to obtain in large numbers throughout the year. Porcellio scaber‚ the most common species is not difficult to identify with the naked eye‚ and is large enough to be handled without employing special techniques. Their behaviour is relatively simple yet providing perfect examples of kinesis and taxis. i A

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

Upper Hutt College Year 13 Biology Slater Study Achievement standard: biology 3.1 Introduction to experiment: In this investigation of the ecological niche of the woodlouse‚ I chose to experiment the amount of soil moisture that the slaters tend to prefer. I chose this aspect‚ as moisture is a vital part in the survival of this small creature. Internet sources provided information of the woodlice that shows that they are from crustacean descent and formerly aquatic even though
