Ph Effect Slaters
Armadillium vulgare taxis response to different pH levels.
Abstract
The terrestrial isopod, Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions, it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such, behavioural and physiological responses of the pill pub are altered in response to distinctive conditions in its environment. The experiment was conducted utelising the variable of pH in order to determine taxis response of the pill bug. The experiment was conducted in a container, which was divided in half with a pH substrate side tested against a control side. The movements and actions of the test slaters were recorded at constant time intervals. The results observed illustrate the preference of a basic NaOH in comparison to the acidic HCI solution. The explanation of this result can be referred against previous studies, which illustrate mechanisms such as conglobation and thigmokinesis employed by slaters in order to create a stable environment whilst in unfavourable conditions.
Introduction
Terrestrial Isopods make up over 1000 different species (water). Armadillium vulgare belong to the order of isopod, however it is more commonly known as a rollie poly, pill bug or slater (azza).
Of the vast ranging crustacean subphylum, Isopoda are the only order to have successfully transitioned from aquatic life to terrestrial habitats (intra) and have colonized on land (water). A. vulgare originated around Mediterranean regions (water pg7). Despite this, they now have much diversity and range throughout continuing regions on the world. This has been achieved by formation of close microhabitat selections and local adaptions (water). Investigations on population dynamics of the A. vulgare have
