In spite of the several studies trying to identify the biological traits that are generally associated with the success of alien plant species, only a few traits are consistently shown to be important. Dividing the species into meaningful sub-categories may improve our ability to distinguish successful alien species. We asked whether there are differences between short-lived and long-lived herbaceous aliens regarding the biological traits associated with their success in their introduced range. We used the source-area approach to answer the question by performing a comparative study with those Central-European herbaceous plant species which are invasive or non-invasive aliens in the United States. Biological traits used in the analysis were extracted from European databases. The significant traits (with one exception) conferred invasiveness for only one of the two life history groups. These results outline a particular combination of competition and colonization in both groups, although achieved in different ways. Short-lived invasive species, which are supposed to be good colonizers with effective reproduction and dispersal, are backed by some kind of competitive ability conferred by height; while in the case of competitive and persistent long-lived species, the successful aliens are equipped with traits that make them better colonizers than other perennial alien species (e.g., tolerance for a wide range of anthropogenic disturbance, dispersal through water).

“…At such large macroecological scales, patterns in species diversity are caused by a variety of ecological and evolutionary processes, as well as historical events and geographical contingencies (Poulin 2004), and distinguishing among these factors is not always straightforward (Desdevises et al 2003). Host ecological traits have received much attention as drivers of species assembly rules in fish parasite communities.…”

The importance of the compound community on the parasite infracommunity structure in a small benthic fish

The extent to which the structure of parasite infracommunities and component communities is determined by the composition of the compound community was assessed by determining the importance of unspecific larval parasites relative to the other guilds (ectoparasites and adult endoparasites). This was analyzed under the hypothesis that the infracommunities harbored by any fish species in coastal waters of the northern Argentine sea will be dominated by unspecific larval stages, which also will be the determinants of the infracommunity structure. These predictions were tested in the Atlantic sea robin, Prionotus nudigula. A total of 1,570 metazoans belonging to 11 species were found in the overall sample (total prevalence = 98%). Larval endoparasites, especially Corynosoma australe and Grillotia sp., were the best represented species, with a deep influence on the infracommunity structure, accounting for the highest proportion of individuals, dominating about 60% of the infracommunities, greatly determining all infracommunity descriptors, and producing marked changes in the similarity among infracommunities. Given the abundance and broad distribution of unspecific larval parasites in the compound community, infracommunities can be considered as subsets of the species available regionally. They are obtained by passive sampling of infective stages as fish feed, and lead to predictable assemblages, with a non-random composition and structure modeled mainly by ecological filters.

“…The combined effect of origin and phylogeny (Desdevises et al 2003) did not explain any additional variation in capitular damage. Although some lineages in our dataset were dominated by exotics and others by natives, this result suggests that any association between exotic status and particular lineages did not consistently bias our results.…”

“…To evaluate the phylogenetic component of herbivory, we used an eigenvector decomposition method (Diniz-Filho and de Sant'Ana 1998; Desdevises et al 2003). Using a principal co-ordinate analysis (PCoA) of the phylogenetic distance matrix from the Asteraceae community phylogeny, 34 eigenvectors were extracted to predict phylogenetically structured damage (n-1 based on 35 species).…”

Phylogenetic structure predicts capitular damage to Asteraceae better than origin or phylogenetic distance to natives

Exotic species more closely related to native species may be more susceptible to attack by native natural enemies, if host use is phylogenetically conserved. Where this is the case, the use of phylogenies that include co-occurring native and exotic species may help to explain interspecific variation in damage. In this study, we measured damage caused by pre-dispersal seed predators to common native and exotic plants in the family Asteraceae. Damage was then mapped onto a community phylogeny of this family. We tested the predictions that damage is phylogenetically structured, that exotic plants experience lower damage than native species after controlling for this structure, and that phylogenetically novel exotic species would experience lower damage. Consistent with our first prediction, 63% of the variability in damage was phylogenetically structured. When this structure was accounted for, exotic plants experienced significantly lower damage than native plants, but species origin only accounted for 3% of the variability of capitular damage. Finally, there was no support for the phylogenetic novelty prediction. These results suggest that interactions between exotic plants and their seed predators may be strongly influenced by their phylogenetic position, but not by their relationship to locally co-occurring native species. In addition, the influence of a species' origin on the damage it experiences often may be small relative to phylogenetically conserved traits.
