-The question of how antlion spatial patterns, such as pit depth, width,

-and nearest neighbor, as well as group behavior vary with respect to

-spatial constraints and interruptions in possible communication pathways

-was examined through the procedure.

-The objective of the research was to expand upon the established

-conclusion from the previous years experiment, which determined that

-antlions space themselves in a hexagonal pattern and maintain a constant

-ratio between all pits to reduce intraspecies competition.

-In order to test the natural hexagonal dispersion pattern of the

-antlions the follow up study aimed to identify the method of

-organization of the organisms, as the previous years study clearly

-illustrated that the organisms had a standard distribution pattern, and

-thereby some means of communicating or understanding spatial information

-in order to achieve that pattern.

-In order to develop a conclusion regarding the method of communication

-three initial hypothesis were made and it was determined that the

-antlions communicated through the use of making trail in the sand, which

-allowed them to mathematically determine a settling position, or that

-the antlions used obstacles and pits as regulatory mechanisms, or

-finally that antlions had no means of communication, but rather their

-cannibalistic nature determined the settlement pattern observed.

-With this in mind a procedure was drafted that contained three distinct

-trials, one where antlion trails were removed, one where fake pits were

-introduced, and one where obstacles were introduced into the

-environment.

-With this procedure  several similar ``cooperative'' behaviors to prior

-studies were observed, with the antlions remaining under the soil when

-the surface was overpopulated (demonstrable by a significantly lower

-number of pits forming in smaller trials).

-Along with this the antlions seemed to be most disrupted by the

-introduction of fake pits, as during these trials the averager pit

-depth, pit width, and nearest neighbor calculation changed

-significantly, thereby indicating that antlions use the presence of pits

-around them to mathematically determine where they need to settle on an

-instinctual level.

+The question of how antlion spatial patterns, such as pit depth, width,
+and nearest neighbor, as well as group behavior vary with respect to
+spatial constraints and interruptions in possible communication pathways
+was examined through the procedure.
+This research expands on a previous study that investigated antlions
+in habitats of, sometimes, extremely small size.
+It found that antlions, as groups, tend to have fewer and smaller pits
+on the surface in smaller areas, to maintain fair food-collection
+densities.
+This follow-up study aimed to identify the regularity of antlions'
+surface distributions, and whether this regularity is maintained if
+trails are removed or the environment is constricted with barriers.
+It was determined that antlions regularize their settlement patterns
+through a couple of innate tendencies: they prefer being on borders when
+possible, to, in a group, use all of the area, and distancing themselves
+from the raised sand around other pits.
+These wouldn't have happened in a system reliant on trail density or
+pheromones (because with trail erasure, regularity was maintained) or in
+a system reliant on cannibalism.
+This experiment tested these specific anti-competitive behaviors,
+building on our previous results, which showed antlions hiding under
+sand when the population got too dense.
