Broadening the extinction debate: population deletions and additions in California and Western Australia
Article Abstract:
Examples from California and Western Australia support the view that a focus on species extinction can lead to failure to appreciate some significant human impacts on biodiversity. Widespread deletion of populations and the addition of invasive species should also be treated with concern, as they can contribute to species extinctions. Data from California and Western Australia on species losses and gains and habitat losses exhibit similar trends in extinctions, contraction of range and invasions.

An evolutionary approach to understanding the biology of invasions: local adaptation and general-purpose genotypes in the weed Verbascum thapsus
Article Abstract:
The importance of evolutionary perspective is discussed outlining a range of potentially useful approaches from population biology to ecological genetics. A study on how adaptation and genetic structure promote the expansion of an invasive weed Verbascum thapsus reveals its success at high elevations confirming to the concept of general-purpose genotype than to invasion by rapid adaptation.

Roads as conduits for exotic plant invasions in a semiarid landscape
Article Abstract:
The cover of exotic and native species in roadside verges and both the richness and cover of exotic and native species in adjacent interior communities along 42 roads stratified by level of road improvement were measured. Roadside verges adjacent to paved and improved surface roads contained a greater cover of both exotic and native species than verges adjacent to four-wheel-drive tracks.
