Article
Native to South Africa, fireweed (Senecio madagascariensis Poiret; Asteraceae) is an annual or short‐lived perennial herb that is highly invasive in Australia, where it is a target for biological control. Preliminary research indicates that fireweed may be undergoing adaptive changes along its invasion gradient in Australia. Changes, such as a shif...
Article
Senecio madagascariensis Poiret (Asteraceae), an invasive herb from southern Africa that inflicts high economic losses in several countries worldwide, is currently a target for biological control in Australia and Hawaii. Several candidate insect agents were identified from the weed’s native range in South Africa. Confirmation of narrow host ranges,...
Article
Competition, herbivory and their interaction play a significant role in determining the competitive ability and survival of individual plant species. Understanding these processes and interactions can improve the efficacy of biocontrol programs against invasive weeds. Senecio madagascariensis (fireweed) is an invasive weed of South African origin t...

Fire has long been recognised as a natural force in structuring Northern Hemisphere salt marshes, yet little is known about the impact of fire on molluscs and native vegetation dynamics of Southern Hemisphere coastal salt marshes. Following a fire at Ash Island, Hunter River New South Wales, Australia in the summer 2012, we assessed patterns of rec...

Invasive plants that displace native floral communities can cause changes to associated invertebrate species assemblages. Using a mini-review of the literature and our own data we add to the still considerable debate about the most effective methods for testing community-level impacts by invasive species. In endangered saltmarshes of southeast Aust...

Invasion by introduced species is a global threat to the natural environment, with major consequences for biodiversity, economies and societies. This paper reviews the literature documenting interactions between introduced and native bird species. Surprisingly, we found only ten cases of an introduced bird being involved in a process that threatene...

Full-text available
Release from natural enemies is considered to potentially play an important role in the initial establishment and success of introduced plants. With time, the species richness of herbivores using non-native plants may increase [species-time relationship (STR)]. We investigated whether enemy release may be limited to the early stages of invasion. Su...
Article
Full-text available
Invasive plants may initially be released from natural enemies when introduced to new regions, but once established, natural enemies may accumulate. How closely related invasive species are to species in the native recipient community may drive patterns of herbivore and pathogen damage and therefore, may be important in understanding the success of...
Thesis
Invasive plants are a global problem, with significant environmental and economic consequences. Reducing the risk that introduced species become invasive is a high biosecurity priority. Much research has been directed at identifying particular biological traits associated with invasion success. Despite some progress in identifying mechanisms and tr...
Article
Within endangered coastal salt marsh of south-east Australia, the non-indigenous rush Juncus acutus L. (Juncaceae) is displacing the native rush Juncus kraussii Hochst. (Juncaceae), with concurrent changes to the structure and composition of insect species assemblages. Here we test hypotheses that the abundance of a common and widespread sap-suckin...
Article
Full-text available
Displacement of native plant species by non-indigenous congeners may affect associated faunal assemblages. In endangered salt marshes of south-east Australia, the non-indigenous rush Juncus acutus is currently displacing the native rush Juncus kraussii, which is a dominant habitat-forming species along the upper border of coastal salt marshes. We s...
