Analysis of the Adaptative Strategy of Cirsium vulgare (Savi) Ten. in the Colonization of New Territories

The current situation of global environmental degradation as a result anthropogenic activities makes it necessary to open new research lines focused on the causes and effects main alterations caused in ecosystems. One most relevant is how niche dynamics invasive species change between different geographical areas, since its understanding key early detection control future invasions. In this regard, we analyzed distribution pattern Cirsium vulgare (Savi) Ten., plant Asteraceae family originally from Eurasian region that currently invades wide areas world. We estimated shifts continents using combination principal components analysis (PCA) Ecological Niche Modelling (ENM) an extensive set data presences native invaded ranges Global Biodiversity Information Facility (GBIF). A bioclimatic variables Human Footprint (HFP) with resolution 10 km were selected for purpose. Our results showed has marked trend expand toward warmer climates less seasonality, although some regions invasiveness appears be than others. models had good statistical performance high coherence relation known allowed us establish relative weight contribution each variable used, annual temperature seasonality being determining factors establishment species. Likewise, use non-climatic HFP provided information explain colonizing behavior methodology adequate selection predictor represents very useful tool when focusing efforts resources management
