Predicting a range shift and range limits in an introduced tropical marine invertebrate using species distribution models

摘要: A major goal of invasion biology is to predict range shifts and potential limits non-native species. Species distribution models (SDMs) are commonly used achieve these goals, but the predictive accuracy rarely tested using natural shifts. The barnacle Megabalanus coccopoma native eastern tropical Pacific has been introduced a number locations globally including southeastern United States. During unusually cold winter months 2010, M. within USA SE retracted 825 km. ability SDM MaxEnt accurately retraction coccopoma’s was distributional data from before after retraction.
