A new study examines how shared pathogens affect host populations

... pathogen. Studying only the target species or the abiotic environment would not reveal the cause of the epidemic. Their results have not only important consequences for understanding the role of pathogens in species interactions but also provide a potential mechanism linking host biodiversity and ecosystem ...

When members of a species become separated, such as geographically, they face different environments, and tend to develop in different directions.
