Ambrosia artemisiifolia L., native to North America, is a problematic invasive species, because of its highly allergenic pollen. The species is expected to expand its range due to climate change. By means of ecological niche modelling (ENM), we predict habitat suitability for A. artemisiifolia in Europe under current and future climatic conditions. Overall, we compared the performance and results of 16 algorithms commonly applied in ENM. As occurrence records of invasive species may be dominated by sampling bias, we also used data from the native range. To assess the quality of the modelling approaches we assembled a new map of current occurrences of A. artemisiifolia in Europe. Our results show that ENM yields a good estimation of the potential range of A. artemisiifolia in Europe only when using the North American data. A strong sampling bias in the European Global Biodiversity Information Facility (GBIF) data for A. artemisiifolia causes unrealistic results. Using the North American data reflects the realized European distribution very well. All models predict an enlargement and a northwards shift of potential range in Central and Northern Europe during the next decades. Climate warming will lead to an increase and northwards shift of A. artemisiifolia in Europe.

The magnetic anomaly map of North America and its related data set provide the opportunity not only to view the obvious short‐wavelength anomalies (<300 km) in a continental context, but to isolate and analyze the longer wavelength anomalies. However, care must be used in analyzing the longer wavelengths because of the effects of noncrustal sources on these anomalies. Inversion of the anomalies into lateral variations of crustal magnetization suggests that the long‐wavelength anomalies (>2600 km) are strongly affected by core field components that have not been completely removed from the North American data set. Furthermore, the piecewise matching of the magnetic anomalies of adjacent survey areas in the map compilation has contaminated the intermediate wavelength anomalies (300–2600 km).

The Psychopathy Checklist-Revised (PCL-R) is a clinician rating instrument for psychopathic personality disorder. Although the instrument is routinely used in forensic assessment in Austria, Germany, and Switzerland, data on its psychometric properties in German-speaking countries are lacking. Based on a national sample of adult male sexual offenders assessed at a federal evaluation unit in Austria (N = 1,046), reliability and factor structure were estimated. More specifically, measurement invariance was assessed with respect to the North American normative data of male offenders. In the sample, the PCL-R achieved similar levels of reliability as those reported in the manual for North American male offenders. According to confirmatory factor analysis, a four-factor model of psychopathy described the data well. More specifically, weak measurement invariance (i.e., equivalence of loadings, not of thresholds) held in comparison with the North American data. The present findings support the suitability of the PCL-R for assessment purposes in German-speaking countries. However, the total score is not directly comparable to North American data given that only weak measurement invariance was observed.
