Abstract:
Semut Leptothorax acervorum memiliki karakteristik kehidupan sosial, diantaranya pembagian peran, keharmonisan, dan kompetisi betina-betina dalam perebutan hak reproduksi di koloninya. Kompetisi yang mematikan ini terjadi baik sesama gyne maupun gyne dengan pekerja. Berdasarkan fenomena yang terjadi pada koloni semut Leptothorax acervorum akan dibangun model matematika. Model ini dibentuk dengan membagi populasi semut menjadi tiga kompartemen, yaitu gyne, pekerja, dan jantan pada populasi Leptothorax acervorum. Fenomena yang menarik seperti kompetisi-kompetisi yang terjadi pada semut Leptothorax acervorum dianalisis dan kestabilan koeksistensi juga akan ditunjukkan secara analitik. Selanjutnya, untuk melihat pengaruh kompetisi terhadap koeksistensi dalam koloni akan ditunjukkan dengan simulasi numerik.

Abstract:
The Dufour glands of Leptothorax acervorum and L. nylanderi both contain species-specific mixtures of hydrocarbons, dominated by C17 hydrocarbons in L. acervorum and C15 hydrocarbons in L. nylanderi. Both species contain the sesquiterpenoid tetramorene-2. but neither contain (E)-β-farnesene, which has earlier been found in the glands of Harpagoxenus sublaevis which raids Leptothorax nests and enslaves its workers. The contents of the glands of workers and queens of L. acervorum were very similar.

Abstract:
We report on the occurrence of the ant Leptothorax kutteri Buschinger, 1965 in two sites in Northern and Eastern Turkey. Leptothorax kutteri is a workerless inquiline living in the colonies of L. acervorum (Fabricius, 1793) so far known from various parts of Northern and Central Europe. Our findings greatly increase the range of this small and rare ant.

Abstract:
Abstract In social insects, workers of different morphological castes and age are known to act differently. Yet, it is unclear how body size and ovarian development influence worker personalities (i.e. consistent behavioral variation) and task allocation in similar aged ant workers of monomorphic species. Behavioral variation is thought to be a key element of division of labor, but few studies have linked worker personality to task allocation. We investigated individual behavior in Leptothorax acervorum ant workers at two time points during the first three months of their life and in two different settings. We observed worker behavior in the nest (i.e. task allocation) and in standardized aggression, exploration and brood care experiments (i.e. personality) and found behavioral repeatability in foraging and exploration. Further, workers acted consistently across settings: workers with a more aggressive and exploratory personality type were more active in the nest. Moreover, ovarian development was associated with worker personality and task allocation: older workers with well-developed ovaries foraged less, but were more aggressive and exploratory. In accordance with the typical age-polyethism of social insects, workers became more active and foraged more as they grew older. Consequently, our study suggests that task allocation in Leptothorax acervorum is not only influenced by ovarian development and age, but moreover by the personalities of its workers.

Abstract:
Eusocial species show incredible variation in all aspects of social living, which has facilitated their ecological success. Investigating the mechanisms which regulate variation in social traits is an important goal for evolutionary biology, since understanding fundamental mechanisms underpinning variation can inform social evolutionary theory. In this thesis, I investigate aggressive behaviour and genome architecture as essential mechanisms in regulating variation in the polymorphic social phenotype of the multiple queened ant species L. acervorum. I investigated the role of enforcement behaviour in maintaining reproductive skew in functionally monogynous colonies. I show that in the absence of worker aggression (enforcement), functionally monogynous queens continue to engage in highly aggressive interactions and, crucially, high colony skew was not affected. Furthermore, I show that low skew is not affected by aggressive worker enforcement in polygynous colonies. Therefore, enforcement behaviour is likely to be important in regulating skew in functionally monogynous colonies but not in polygynous colonies, where potentially the loss of sensitivity to enforcement may be an evolved response to fitness benefits associated with the polygynous social phenotype. Furthermore, I investigated the role of genome architecture in regulating variation between the two social phenotypes. I scanned the genomes of four populations (two polygynous and two functionally monogynous) for extreme population differentiation (FST) at SNP loci, which were associated with a difference in the social phenotype. I found a large (6.2Mb) contiguous region associated with different social phenotypes (the social region), which mapped to LG2 on the S. invicta linkage map. The social region displayed some similarities with the social chromosomes in S. invicta and F. selysi. Furthermore, the region contained potential gene candidates, such as odorant binding proteins, which have been associated with divergent social phenotypes in S. invicta. The work presented in this thesis highlights the importance of different mechanisms, both behavioural and genomic, in regulating variation in fundamental social traits. Furthermore, it demonstrates the importance of understanding how mechanisms can bridge the gap between genotype and phenotype.

Abstract:
A novel approach of integrating two swarm intelligence algorithms is considered, one simulating the behaviour of birds flocking (Particle Swarm Optimisation) and the other one (Stochastic Diffusion Search) mimics the recruitment behaviour of one species of ants – Leptothorax acervorum. This hybrid algorithm is assisted by a biological mechanism inspired by the behaviour of blood flow and cells in blood vessels, where the concept of high and low blood pressure is utilised. The performance of the nature-inspired algorithms and the biologically inspired mechanisms in the hybrid algorithm is reflected through a cooperative attempt to make a drawing on the canvas. The scientific value of the marriage between the two swarm intelligence algorithms is currently being investigated thoroughly on many benchmarks, and the results reported suggest a promising prospect (al-Rifaie, Bishop & Blackwell, 2011). It may also be discussed whether or not the artworks generated by nature and biologically inspired algorithms can possibly be considered as computationally creative.
