Última Exotic plant invasions to the mediterranean region of Chile: causes, history and impacts RChHN FIGUEROA,JAVIER A.; CASTRO,SERGIO A.; MARQUET,PABLO A.; JAKSIC,FABIAN M.. We review the literature on patterns, causes, processes and impacts of exotic plants, primarily in the mediterranean region of Chile, considering three major non-independent drivers of the invasion process: (a) Availability of exotic species propagules, (b) attributes of the local communities in which exotic species establish and through which they will eventually spread out, and (c) attributes of exotic species that either facilitate or constraint their spread into new sites. Regarding availability of propagules, central Chile matorral presents the communities with the greatest incidence of naturalized herbs, followed by the sclerophyllous forest and the espinal scrubland in the coastal range. In contrast, north-central communities have lower numbers and... Tipo: Journal article Palavras-chave: Exotic species; Plant invasions; Naturalized plants; Invasion history; Ecosystem disruption.

The current geographical distribution of alien species could be informative of processes involved in the biological invasions facilitated by humans. Because environmental and anthropic factors affect the geographic distribution of alien plants, we hypothesize that naturalized plants have a non-random distribution along extensive geographical ranges. On the basis of a complete and updated database of naturalized plants in Chile, we analyzed their turnover and floristic similarities among regions that encompass a wide latitudinal gradient in South America. Using Moran's index and Mantel's test we characterized the spatial auto-correlation (regional aggregation) and the effect of geographical distance on the index values. Additionally, we used clustering... Tipo: Journal article Palavras-chave: Jaccard's index; Whittaker's index; Plant invasions; Naturalized plants; Similarity; Turnover.
