	Porcellio Scaber Behavior
		The Porcellios are a group of animals that are grayish in color and when it is disturbed it tends to quickly run away.
		Porcellio scaber show a kinesis type response to moisture.
		They show both an increased speed of movement, or orthokinesis, and increased rate of turning, or klinokinesis, in dry conditions and slower rates of movement in more damp conditions.

	Porcellio scaber
		It is usually a rather dark steely grey colour, but lighter mottled varieties do occur, and young specimens are very often mottled with yellow and brown.
		Porcellio scaber can be found under stones and logs and it is the commonest species in greenhouses, but it is even more common in bark crevices and on old walls.
		If you take a torch to a tree trunk or a wall on a humid night, you will probably be very surprised at the numbers of woodlice that you will find, and most of them will be Porcellio scaber

		Abstract: Field studies have revealed that female Porcellio scaber seek warmer temperatures than male, this was also confirmed by laboratory experiments.
		It has been show that increassing the temperature of the microhabitat from 15 to 20 degrees C doubles the rate of embryonic development, perhaps explaining the behavior of the females.

		scaber indicates, that in addition to the microorganisms which are just passive travellers through the isopod gut, there are some groups of microorganisms adapted to live in the hindgut.
		The central nervous system of adult Porcellio scaber has been investigated by means of light and electron microscopy, enzyme and immunocytochemistry, extracellular tract tracing (Lucifer yellow and horse radish peroxidase filling).

	WOODLICE HOMEPAGE
		There are 3 of these common species, Oniscus asellus and Porcellio scaber (Common shiny woodlouse and Common rough woodlouse) and Armadillidium vulgare (Common pill bug) that are particularly common around homes and gardens - often entering the house when it is too wet and cold outside!
		Trichoniscus pusillus are definitely known to do this, my own experiments have also shown that Pocellio scaber and Oniscus asellus are also able to produce offspring when they have not mated with a male.

	Woodlice
		The space between the body and this false floor is filled with liquid and the female lays her eggs into it.
		Studies indicate that the eggs of Porcellio scaber take about a month to hatch.
		The fluid then gradually disappears from the pouch and the little woodlice, about the size of a grain of rice, leave after a few days.

	Woodlouse - Wikipedia, the free encyclopedia
		They are usually nocturnal and are detritivores, feeding mostly on dead plant matter, although they can be a destructive pest in the garden.
		In the United Kingdom there are 37 native or naturalised species ranging in colour and in size (3-30 mm) of which only five are common: Oniscus asellus (the common shiny woodlouse), Porcellio scaber (the common rough woodlouse), Philoscia muscorum (the common striped woodlouse), Trichoniscus pusillus (the common pygmy woodlouse) and Armadillidium vulgare (the common pill bug).
		As the woodlouse grows, it must progressivly shed this shell.

		In my brief study, no significant metabolic rate diferences were obtained between Porcellio scaber populations kept at five degrees C, fifteen degrees C, and ambient air temperature for a period of two weeks.
		No significant differences were found for L. 50 measurements either, but due to small sample sizes and a stringent assumption of normality for the analysis used, conclusions cannot be made with any certainty.

	Homework assignment 3
		Oniscus asellus is the only species in the Newark area that has the pleotelson extending almost as far back as the two uropods (the pleotelson is the middle "tail.") It is generally whitish along the edges with a row of whitish spots inside the edges.
		Porcellio scaber is what's left after you've eliminated the other three species.
		It doesn't roll into a ball, the abdomen is not abruptly narrower than the thorax, and the uropods extend back much farther than the pleotelson.

		Some species of Scorpion, such as Pandinus imperator (The Emporer) will eat almost anything that they can hold onto providing it is alive.

		Ligia oceanica (Common Sea Slater) is the largest species in Britain, up to 30 mms long, it lives only on the seashore and feeds mainly on the brown seaweed Fucus vesiculosus, while Porcellio scaber a common woodland species likes to feed on tree bark but will eat many oter things.
		Armadillidium klugii from Dalmatia is a spider mimic and looks like the poisonous Laterodectes mactans especially when young.
