This study investigates classical scrapie (CS) and the risk of interspecies prion transmission by using presence data from wild cervids and infected small ruminant flocks. Employing remote sensing technologies, it derives vegetative and biophysical satellite indices to represent habitat features. A species distribution model integrates these data to identify suitable areas for CS and its hosts. The resultant consensus map and overlapping suitable areas create a detailed infection risk matrix.

Using eDNA to study fish communities in river–lake systems is a new, cost-effective method. Our study found that water eDNA might miss some fish living in the sediment. Fish communities in rivers and lakes are quite similar, showing how connected these systems are. The environment, especially temperature, influences the genetic signals found in water and sediment. This research sheds light on the effectiveness of eDNA in understanding aquatic ecosystems.

The study examined how terrestrial mammals' diets vary across geography. It found that herbivory is more prevalent in cold and desert areas, while frugivory and insectivory dominate in tropical regions. Granivory dominates in temperate environments, while carnivory is more common in the Northern Hemisphere and towards the poles. Terrestrial mammals' diets show conspicuous geographical patterns across the globe, partially explained by climate.
