Chemosensory gene expression analysis in the argentine ant, linepithema humile
… proteins (OBPs), in the invasive Argentine ant, Linepithema humile. Fragments of two Ors were identified from a whole ant EST project, which suggested their potential importance in Argentine ant ecology. An initial RT-PCR experiment demonstrated that OrA and OrB were expressed throughout the …

Impact of the invasive ant Linepithema humile on native ant assemblages on the western slopes of Table Mountain and implications for ant-butterfly associations
The Argentine Ant, Linepithema humile (Hymenoptera: Formicidae), is one of the world's most successful invasive species and invades undisturbed Fynbos habitats in South Africa, displacing native arthropod species and affecting interspecific associations. In order to assess the impact of Li. humile …

The evolution of caste-specific morphology and colony structure in ants
… castes. In chapter 3, I used the ant genus Linepithema to examine intra and interspecific variation in morphology and colony structure. Despite our general understanding of caste differentiation, there are few studies quantifying morphological variation within and among reproductive females, …

The impact of pine plantations and alien invertebrates on native forest and fynbos invertebrate communities in Table Mountain National Park
… invasive alien invertebrate (Argentine ant, Linepithema humile) and other alien invertebrate species are investigated. This is one of the first attempts to inventory and quantify impacts of non-ant alien invertebrates in Table Mountain National Park. The entire ground-dwelling invertebrate …

Effects of fragmentation and invasion on ant communities
… of changes in the impact of the Argentine ant (Linepithema humile) in this area with time. I revisited each of the 40 fragments sampled previously and found that the abundance of this invader has increased while the native ant community has not rebounded to preinvasion levels, which supports the …
