Woodlice behaviour towards light and darkness experiment

Experimental set up The basic experimental set up consisted of a homogeneous arena PVC tube, mm in diameter with a small removable central arena 65 mm of diameter where woodlice were placed before the beginning of the experiment in order to calm them down cf. A repetition of the same experiment using the same apparatus did not help, again probably because of an unrestrained filter paper setup error. The adaptations can be structural [18] , physiological [3] , [19] , [20] , or behavioural [21]. The results are quite notably. At its most basic, aggregation is just a grouping of animals [34]. I had some problems with each setup structure and its respective rules and specific observations, but after the first experiment was conducted the rest came along smoothly. An example improvement like the aforementioned would be very possible in that case. The woodlouse eggs hatch after an incubation period of just a few days exposing the woodlouse babies. However, the chemical nature of the pheromone is still unknown [43]. Woodlice have a great ecological role in the decomposition process due to their digestive capabilities [3]. Pseudotracheae assist respiration in dry air. Using new stimuli such as food available and object density i. Especially with controlled variables like the moisture levels on the filter paper that ruined part of this experiment. Although the woodlice moved towards the predicted sections most of the time, there was some strolling around at times.

In this respect, it may control different density dependent processes and may influence the dynamics of population at large spatio-temporal scale [11]. The woodlouse is found in nearly every environment in the world besides the polar regions and the arid desert.

The woodlouse is generally about 1 cm long but many species in the tropics are triple that sizesome are even bigger.

The woodlouse is found in dark, damp places in forests and jungles throughout the world. Using new stimuli such as food available and object density i. In a medium, room temperature situation all woodlice appear to stay mixed and walk around a lot. This means that only the hard outer shell of the woodlouse is exposed. Woodlice have a great ecological role in the decomposition process due to their digestive capabilities [3]. Using the metal lattice did not always go smoothly and sometimes plainly failed. Very little information is available on the inter-attraction between woodlouse individuals. In the event of better preparation and better time management, more variables could have been added and thus a higher standard of realism could have been reached. The objective of this paper is to show that in woodlice, inter-attraction is at work, and how its synergy with individual preferences governs the dynamics and the patterns of aggregation. Introduction There are about 10, described species of isopods [1] , and nearly half of them are terrestrial and belong to the suborder Oniscidae [2]. Using natural conditions and predicted reflexes I was able to quite accurately predict what behaviour the woodlice would apply in each situation. A litter of maple, beech, and oak leaves also formed their food resources.

However, some behavioural adaptations are related to groups of individuals. In a medium, room temperature situation all woodlice appear to stay mixed and walk around a lot. In a case of moist and dry conditions, it would be much more favourable for the woodlice to stay at the moist areas.

Toads, centipedesspiders, millipedes and the occasional wasp are the main predators of the woodlouse. Further information is needed along three lines: i precise microclimatic measurements linked with observations of behaviour in the field, ii laboratory analysis of orientation mechanisms, iii neurophysiological investigation of the sensory mechanisms involved.

Experimental set up The basic experimental set up consisted of a homogeneous arena PVC tube, mm in diameter with a small removable central arena 65 mm of diameter where woodlice were placed before the beginning of the experiment in order to calm them down cf.

where do woodlice live

Another mechanism of aggregation is that resulting from inter-attraction between conspecifics which defines gregarious species [38][39].

Also the higher temperatures cause water to evaporate at a quicker rate, which 11 they are thus naturally trying to avoid. Until now, no clear experimental demonstration was available about aggregation resulting from inter-attraction between conspecifics.

why do woodlice prefer damp conditions

Ultimately, I think that the results are acceptable and do represent a realistically simulated natural environment for woodlice.
