  1. 1. Evolution and consequences of polygyny in leptothoracine ants

    University dissertation from Marie Stille, Department of Zoology, Helgonavägen 3A, S-223 62 Lund, SWEDEN

    Author : Marie Stille; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mtDNA; allozymes; social parasitism; sex ratio; budding; colony founding; relatedness; polygyny; Leptothorax; Ants; leptothoracine; RFLP; CO-I; Zoology; Zoologi;

    Abstract : In this thesis the evolution and consequences of multiple queen societies (polygyny) in leptothoracine ants are discussed. The majority of the studies have been conducted on the boreal species Leptothorax acervorum, but polygynous behaviour is also discussed in a broader sense concerning ant species in general. In L.
