Formica planipilis ( Thatch ants)  Habitat

 Queen Ant  Male Ants  Colony life cycle  Workers

 The study by Peter Nonacs, PhD Investigates: Total sample size 1199 Ants Size Distance  Foraging Habits  Data 11 Colony Determine that there’s a relationship between distance travelled by ants and the worker class group Samples were collected at varying distances using traps

 Statistical Tests & Analyses  One Way Analysis of Variance  Assumption Kruskal-Wallis Normality Test: Failed  Multiple Comparison Procedure vs < Yes Dunn’s method

GroupN Missing Median 25% 75% < > (  Results H = with 5 degrees of freedom. (P = <0.001) The Dunn’s multiple comparison analysis produce a significant difference for only one comparison (40-43 vs 30) with Q=4.221 and P < 0.05, while the others were insignificant.

 Conclusion There is a significant difference in the distance travelled among the varying worker classes. Thus, there is a relationship between the worker class and the foraging distance of the thatch ant.
