Activity patterns and interactions of rodents in an assemblage composed by native species and the introduced black rat: implications for pathogen transmission
Background: The degree of temporal overlap between sympatric wild hosts species and their behavioral interactions can be highly relevant to the transmission of pathogens. However, this topic has been scantly addressed. Furthermore, temporal overlap and interactions within an assemblage of wild roden...

All rodent species in this study are known hosts for various zoonotic pathogens. Results: We found a high nocturnal temporal overlap within the rodent assemblage.

Rattus rattus showed aggressive behaviors against all native rodents more frequently than against their conspecifics.

Background: The degree of temporal overlap between sympatric wild hosts species and their behavioral interactions can be highly relevant to the transmission of pathogens.
