Biology Investigation Woodlice - 1925 Words

* 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 area to volume ratio. This results in a variety of behavioural adaptations that help it conserve moisture and avoid desiccation. The woodlouse exhibits negative phototaxes behaviour, this results in them moving away from brighter areas in†¦show more content†¦Draw a 2cmx2cm grid with the crayon covering the section of black paper. 11. Place the bucket onto the grid with the open end facing down. 12. Trace the buckets circumference onto the black paper with the crayon. Dot the square in the centre of this circle. This will be the starting point for the woodlice. 13. Turn on the bulb to the specific voltage for the trial. 14. Take readings for Lux, Humidity and Temperature (In this investigation, readings were taking by putting the sensor up through the lip of the bucket). In future trials attempt to match them to these readings. It is more efficient to do all trials on the same day to make sure of the same humidity and temperature. 15. Place woodlouse onto starting square and quickly start the stopwatch while counting the number of squares the woodlouse moves. 16. After 2 minutes stop the stopwatch and note the amount of squares the woodlouse travelled in that time. 17. Repeat steps 13-16 for each specific voltage. 18. Change woodlice and start the next set of trials. 19. Repeat until 7 trials have been conducted.

Rotenone is a NADH dehydrogenase inhibitor causing death by oxidative stress however pirimicarb causes toxicity through acetylcholinesterase inhibition. It was found that rotenone had large toxic effects on daphnia, blowflies and woodlice but not maggots and pirimicarb had low toxic effects onRead MoreSlater Study2592 Words   |  11 PagesUpper 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.
