ment , i . e . a transform , the contexts need to be defined . Robinson ( 1996 , 85-88 ) distinguishes a domestic , peridomestic and natural environment . For practical purposes , the peridomestic and natural areas here are subdivided into a local and a non-local area , to distinguish autochthonous from alloch thonous taxa ( figure 1 ). The domestic area is the local dwelling that is attached to the local peridomestic area . A house in an urban setting would have a property where activities take place that are linked to those in the home . For example , food preparation and consumption results in waste that may be deposited in features in the garden . There are many possible peridomestic features , such as a vegetable plot or a cesspit , or buildings such as stables , which are never domestic dwellings themselves . The local natural area encompasses the natural features in close proximity to or overlapping the peridomestic area . The non-local natural area is located elsewhere , and may be represented through imported

The non-local peridomestic area is any peridomestic area not directly attached to the home , and may be represented through imported cultivated resources . These make up five conceptual systemic contexts , while the archaeological context is the waste- or cesspit , a peridomestic feature . The possible movement of arthropods , whether as individuals or within a deposit , between these systemic contexts towards deposition is represented in figure 2 , also showing the different trajectories of N- and C-transforms .
The assemblage movement from and between the systemic contexts will ultimately result in deposition in the archaeological context . Therefore , the arthropod assemblage of a pit is an accumulated mixture of assemblages . In order to separate these , the overall assemblage is subdivided into four sub-assemblages .
Sub-assemblages : a division based on systemic context origin Separating species communities allows for a better understanding of a deposit , but it will also make interpretation of the relative abundance of species possible , as there may have been a natural or anthropogenic selective process that resulted in over- or underrepresentation of species . Dumping a weevil-infested bag of grain into a pit will make a vast majority of the sample grain weevil , while this is solely based on one event , possibly blurring out other less abundant species . Although it is useful to identify an event , the superabundance of a taxonomic group might overshadow the ecological implications of smaller groups , for example statistically or in a visual representation .
