Consistent performance of invasive plant species within and among islands of the Mediterranean basin

REA Auditado

Since the success of an invasive species depends not only upon its intrinsic traits but also on particular characteristics of the recipient habitat, assessing the performance of an invader across habitats provides a more realistic analysis of risk. Such an analysis will not only provide insights into the traits related to invasiveness, but also the habitat character- istics that underpin vulnerability to invasion that, taken together, will facilitate the selection of management strategies to mitigate the invader’s effect.

Widespread resistance of Mediterranean island ecosystems to the establishment of three alien species

REA Auditado

Although some invasive plants are cosmopolitan, not all ecosystems are invaded to the same degree. Yet there is little experimental work on how ecosystem resistance to invasion at the establishment phase differs among ecosystems. We conducted two field sowing experiments in two consecutive years to examine establishment of the deciduous tree Ailanthus altissima, the succulent subshrub Carpobrotus spp.

Clonal growth dynamics of the invasive Carpobrotus affine acinaciformis in Mediterranean coastal systems: a non-linear model

REA Auditado

Carpobrotus affine acinaciformis is one of the most harmful invasive plants in the Mediterranean basin. In this study, we built a numerical growth model containing simple, and essentially linear, growth rules that provided us a tool capable to analyse the complex non-linear behaviour observed in the dynamic growth of Carpobrotus spp.
