A morphometric study of the ant species,Myrmecia dispar (Clark) (Hymenoptera: Formicidæ)
Tóm tắt
Myrmecia dispar (Clark) workers and queens show monomorphic polymorphism with limited size variation. Significant differences were found for the mean values of certain characters of workers between some colonies. Frequency histograms of head width against the number of workers in a colony varied considerably, with little or no definite pattern for the smaller colonies and ranging from unimodal to bimodal histograms for the larger colonies. Highly significant, positive, correlation values were obtained for all measured characters in each colony. Partial correlation analysis revealed much of this correlation to be due to similar growth coefficients. Regression analysis indicated that the characters head width and pronotal width were linearly related.
