nvestigation into the Factor of Light and Dark Affecting Woodlice Predictions It was expected that a woodlice would prefer a damp‚ dark‚ but moderately warm surrounding. Normally one would expect to find slaters under logs or concrete slabs in one’s garden. Under these large objects‚ the sun cannot reach directly; therefore it is darker‚ damper and colder than the surroundings. Nevertheless‚ in winter we do not see woodlice crawling around very often‚ and‚ also at night‚ it may

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

* 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

fourteen jointed limbs. Woodlice form the suborderOniscidea within the order Isopoda‚ with over 3‚000 known species. The woodlouse has a shell-like exoskeleton‚ which it must progressively shed as it grows. The moult takes place in two stages; the back half is lost first‚ followed two or three days later by the front. This method of moulting is different from that of most arthropods‚ which shed their cuticle in a single process. Metabolic rate is temperature-dependent in woodlice. In contrast to mammals

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

To investigate the habitats woodlice prefer is dark condition or wet condition 1. Use a shoebox and place some soil and dry leaves in it. Start looking under rocks or bricks for some woodlice and place them in the shoebox. Make sure the soil is placed enough and evenly to keep the woodlice happy when not under investigation. * 25 woodlice were used for the experiment because the more woodlice used increases the statistics of which condition the woodlice prefer and give a more accurate data

A habitat is an ecological or environmental area that is inhabited by a particular species of animal‚ plant‚ or other type of organism.[1][2] It is the natural environment in which an organism lives‚ or the physical environment that surrounds a speciespopulation.[3] A habitat is made up of physical factors such as soil‚ moisture‚ range of temperature‚ and availability of light as well as biotic factors such as the availability of food and the presence of predators. A habitat is not necessarily a

28/09/12 Grace Masters Woodlice Behavior Experiment Aim: To investigate the effect of light intensity on the behavior of woodlice (Porcellio scaber) in regards to their change in speed. 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

Habitat fragmentation is occurring in all major habitats found throughout the world at various speeds and levels of severity. Habitat fragmentation
