Abstract
The establishment of non-indigenous species (NIS) has become a global phenomenon and is acknowledged as one of many potential threats against biodiversity and the functioning of marine ecosystems. To support effective management there is a need to predict NIS distribution and identify areas with the highest invasion risk. In this study we have developed local species distribution models by combining observations of one of the top-tier invasive NIS, the round goby Neogobius melanostomus, with high resolution maps of environmental conditions along the Baltic Sea coast of south-eastern Sweden. By applying the model with and without spatial constraints we estimate the current and potential distribution. The difference between these two maps outlines high risk areas for potential colonization, should round goby continue to spread in accordance with environmental preference in the area. We additionally highlight the significance of scale for distribution modelling by comparing the importance of local environmental conditions to variables important on a regional scale.
