An Analysis of Agressive Interactions Between Procambarus Spiculifer and Procambarus Versutus in Laboratory-Based Interspecific Contacts
Abstract
dc:description.abstract<p>The study was undertaken to investigate the role of competitive behavior in the distribution of the crayfish Procambarus spicullfer and Procambarus versutus. Forty pairs of animals, one of each species per pair, were matched by size and gender. For each pair, four fifteen minute agonistic encounters were observed under controlled laboratory conditions, and winners were determined using a scoring system developed by the author. P. versutus won 26 of 40 contests. Chi Square analysis revealed that this outcome deviated from an expected 50/50 ratio at the .942 significance level, suggesting support for the hypothesis that no difference exists in competitive behavior outcomes between the two species at the .05 confidence level. Chi Square analysis by sex revealed no significant difference between the six P. spicullfer and seven P. versutus winners. However, the result was significant in the eight male P. spicullfer and 19 P. versutus winners. The derived Chi Square value of 4.48 was significant at a confidence level of 96.57%.</p>
