Equilibrium or not? Modelling potential distribution of invasive species in different stages of invasion

Popis výsledku v původním jazyce

Aim The assumption of equilibrium between organisms and their environment is a standard working postulate in species distribution models (SDMs). However, this assumption is typically violated in models of biological invasions where range expansions are highly constrained by dispersal and colonization processes. Here we examined how stage of invasion affects the extent to which occurrence data represent the ecological niche of organisms and in turn influences spatial prediction of species' potential distributions. Location Six ecoregions in western Oregon, USA. Methods We compiled occurrence data from 697 field plots collected over a nine-year period (2001-2009) of monitoring the spread of the invasive forest pathogen Phytophthora ramorum. Using these data we applied ecological niche factor analysis to calibrate models of potential distribution across different years of colonization. We accounted for natural variation and uncertainties in model evaluation by further investigating three
