Long-Distance, Transfrontier Carnivore Dispersals in Southern Africa.

Information on long-range dispersal in tropical carnivores is limited compared to their temperate counterparts. Here we present data on long-range, transboundary dispersals for three species of tropical carnivores: African wild dog (), African lion (), and spotted hyena (). The dispersals we document in our savannah system are among the longest that have been recorded for African wild dog and African lion, while for spotted hyena one of our recorded dispersal events is of similar magnitude to the longest documented movements occurring among any carnivore species from around the world.

Development of a supramolecular solvent-based extraction method for application to quantitative analyses of a wide range of organic contaminants in indoor dust.

This study investigates the efficacy of supramolecular solvent (SUPRAS) in extracting a diverse spectrum of organic contaminants from indoor dust. Initially, seven distinct SUPRAS were assessed across nine categories of contaminants to identify the most effective one. A SUPRAS comprising Milli-Q water, tetrahydrofuran, and hexanol in a 70:20:10 ratio, respectively, demonstrated the best extraction performance and was employed for testing a wider array of organic contaminants.

Targeted PFAS analyses and extractable organofluorine - Enhancing our understanding of the presence of unknown PFAS in Norwegian wildlife.

With the current possible presence of thousands of PFAS compounds in industrial emissions, there is an increasing need to assess the impacts of PFAS regulation of conventional PFAS on one hand and the exposure to emerging and yet unknown PFAS on the other. Today's analytical methodologies using targeted approaches are not sufficient to determine the complete suite of PFAS present. To evaluate the presence of unknown PFAS, we investigated in this study the occurrence of an extended range of target PFAS in various species from the marine and terrestrial Norwegian environment, in relation to the extractable organofluorine (EOF), which yields the total amount of organofluorine.

Restore politics in societal debates on new genomic techniques.

End of April 2021, the European Commission published its study on New Genomic Techniques (NGTs). The study involved a consultation of Member States and stakeholders. This study reveals a split on whether current legislation should be maintained or adapted to take account of scientific progress and the risk level of NGT products.
