Coevolution between native and invasive plant competitors: implications for invasive species management
Invasive species may establish in communities because they are better competitors than natives, but in order to remain community dominants, the competitive advantage of invasive species must be persistent. Native species that are not extirpated when highly invasive species are introduced are likely to compete with invaders. When population sizes and genetic diversity of native species are large...
متن کاملModeling disturbance-based native invasive species control and its implications for management.
Shifts in disturbance regime have often been linked to invasion in systems by native and nonnative species. This process can have negative effects on biodiversity and ecosystem function. Degradation may be ameliorated by the reinstatement of the disturbance regimes, such as the reintroduction of fire in pyrogenic systems. Modeling is one method through which potential outcomes of different regi...
متن کاملInvasive plant Alternanthera philoxeroides suffers more severe herbivory pressure than native competitors in recipient communities
Host-enemy interactions are vital mechanisms that explain the success or failure of invasive plants in new ranges. We surveyed the defoliation of invasive Alternanthera philoxeroides and co-occurring native plants on two islands during different seasons over three consecutive years and measured the leaf nitrogen content and the C/N ratio of each plant species. To evaluate the effects of herbivo...
متن کاملExploitative competition between invasive herbivores benefits a native host plant.
Although biological invasions are of considerable concern to ecologists, relatively little attention has been paid to the potential for and consequences of indirect interactions between invasive species. Such interactions are generally thought to enhance invasives' spread and impact (i.e., the "invasional meltdown" hypothesis); however, exotic species might also act indirectly to slow the sprea...
متن کاملNon-native invasive species and novel ecosystems
Invasions by non-native species have caused many extinctions and greatly modified many ecosystems and are among the major anthropogenic global changes transforming the earth. Beginning in the mid-1980s, a dramatic burst of research in invasion biology has revealed a plethora of previously unrecognized impacts and laid bare the scope of the phenomenon. Similarly, research on various methods of m...
