Morfologia e histoquímica de glândulas intramandibulares em espécies representantes de Attini e Ponerini (Hymenoptera, Formicidae)
… em formigas primitivas Ponerini (Ponerinae) e derivadas Attini (Myrmicinae). Nessas formigas foram encontradas glândulas da classe I e III e, células epiteliais secretoras com reservatório. As glândulas intramandibulares apresentam histologia distinta nas espécies estudadas, …

Differentiation in reproductive potential and chemical communication of reproductive status in workers and queens of the ant Myrmecia gulosa
… on several "primitive" ants from the subfamily Ponerinae and two highly eusocial Hymenoptera species. In the former, the dominance hierarchies allowing for the establishment of individuals as reproductives are well understood. In contrast, the pheromonal mechanisms that help maintain their …

The evolution and functional morphology of trap-jaw ants
… of trap-jaw ants are found in the subfamily Ponerinae, and consist of the sister genera Anochetus and Odontomachus. In Chapter 2, I present my findings from the first comprehensive worldwide phylogeny for these two trap-jaw ant genera. Using molecular sequence from four nuclear and one …

Co-operation and conflict in societies of the ponerine ant genus Pachycondyla
A significant relatedness is of fundamental importance for the evolution and maintenance of social life (kin selection theory, Hamilton 1964a,b). Not only kin selection itself, but also more complex evolutionary theories make predictions on the occurrence of conflict and co-operation in animal …

Safer without Sex?
… In the phylogenetically primitive subfamily Ponerinae reproductive caste dimorphism is much less pronounced: Ovarian morphology is rather similar in queens and workers, which additionally retain a spermatheca. In many ponerine species workers mate and may have completely replaced the queen …

Paarungshäufigkeit und Aufteilung der Reproduktion bei Pachycondyla villosa
In Ameisensozietäten treten häufig Konflikte um die Reproduktion auf. Um dabei das soziale Verhalten der beteiligten Individuen und die Koloniestruktur zu verstehen ist es wichtig, die Verwandtschaftsstruktur innerhalb der Kolonien zu kennen. Diese wird durch die Paarungshäufigkeit der Königinnen, …
