Straub | The publisher of Ecological Modelling would like to announce the following. Due to a clerical error on our part there is a gap in page numbers between Ecological Modelling issue 181/2–3 and 181/4. 181/2–3 ends with 286 whereas 181/4 starts with 445 (instead of 287). The missing page numbers will not be used. We want to assure all authors and readers that this has no consequences for citing the papers in 181/4.
