Road verges as invasion corridors? A spatial hierarchical test in an arid ecosystem
Disturbed habitats are often swiftly colonized by alien plant species. Human inhabited areas may act as sources from which such aliens disperse, while road verges have been suggested as corridors facilitating their dispersal. ...
Invasive alien plants infiltrate bird-mediated shrub nucleation processes in arid savanna
1 The cultivation and dissemination of alien ornamental plants increases their potential to invade. More specifically, species with bird-dispersed seeds can potentially infiltrate natural nucleation processes in ...
Residence time and potential range: crucial considerations in modelling plant invasions
A prime aim of invasion biology is to predict which species will become invasive, but retrospective analyses have so far failed to develop robust generalizations. This is because many biological, environmental, and ...
Global Invasive Alien Species Indicator Database
Database of invasive alien species (including plants, mammals, birds, fish and amphibians) present in 57 countries, with references for impact and spread information.
Interactions among multiple invasive animals
(Ecological Society of America, 2015)
With accelerating rates of invasion being documented in many ecosystems, communities of interacting invasive species are becoming increasingly common. Opposing theories predict that invaders can either hinder or promote ...
Niche differentiation among invasive crayfish and their impacts on ecosystem structure and functioning
(John Wiley & Sons Ltd, 2014)
1. Many aquatic ecosystems sustain multiple invasive species and interactions among them have important implications for ecosystem structure and functioning. Here, we examine interactions among two pairs of invasive crayfish ...
Worldwide spread of the Argentine ant, Linepithema humile (Hymenoptera: Formicidae)
(Austrian Society of Entomofaunistics, 2009)
The Argentine ant, Linepithema humile (MAYR, 1868), originally from subtropical South America, is an important pest in many parts of the world. To evaluate its worldwide distribution and potential for further spread, we ...
Trophic overlap between fish and riparian spiders: potential impacts of an invasive fish on terrestrial consumers
(John Wiley & Sons Ltd., 2016)
Studies on resource sharing and partitioning generally consider species that occur in the same habitat. However, subsidies between linked habitats, such as streams and riparian zones, create potential for competition between ...
Dominance–diversity relationships in ant communities differ with invasion
(John Wiley & Sons Ltd, 2018)
The relationship between levels of dominance and species richness is highly contentious, especially in ant communities. The dominance-impoverishment rule states that high levels of dominance only occur in species-poor ...
Tall-statured grasses: a useful functional group for invasion science
Species in the grass family (Poaceae) have caused some of the most damaging invasions in natural ecosystems, but plants in this family are also among the most widely used by humans. Therefore, it is important to be able ...
