The distribution and ecology of invasive ant species in the Pacific region
Invasive ant species represent a major threat to biodiversity through their detrimental impacts on native ecosystems. An important step to managing invasive ant species is determining the factors responsible for their current and potential distribution. This thesis examines the spatial distribution …

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 …

Assessing risk to native ecosystems: using exotic ants as a model
Invasive species are widely recognised as drivers of ecological change. As such, understanding the processes that facilitate invasion success, and the potential mechanisms and magnitude of impact, are critical for effective biosecurity management. Predicting risk associated with exotic species, so …

Spread of Red Imported Fire Ant, Solenopsis invicta, in Virginia and effects of sub-lethal exposure to agrochemicals on its behavior
Solenopsis invicta is an invasive ant that has caused detrimental impacts to ecosystems and economies in the Southeastern United States, recently including Virginia. In this study, we explored the invasion ecology of S. invicta through two main objectives. First, we established a comprehensive …

The consequences and implications of ecology on body size distributions in social insects
… Additionally, in approximately 13% of ant species worker variation is large enough that the worker caste can be subdivided into sub-castes based on size and shape. For these polymorphic species, body size is both an individual and a colony-level trait (distribution of worker body …
