چکیده
Strategies for the prevention and control of commensal rodents would improve with better knowledge their response to environmental factors from different spatial scales. In this research we evaluated which scales characteristics determine rodent infestation levels in a subtropical urban rural landscape gradient Misiones, Argentina. A total 87 households an urban, periurban were surveyed at least once, nine repeatedly along five consecutive seasons. Rodent estimated using nontoxic bait stations set up backyard garden each household. Different several obtained field surveys land cover classification based on satellite image. Rattus spp. was detected 42.5% households. The lowest infestations occurred winter. Infestation showed dependence 2500 m. associated types macro microhabitat Macrohabitat explained 53.7% variation levels, whereas microscale 28.0% type only 2%. This multiscale study provides evidence that households’ may not be most important factor explain variations abundance rodents’ around human dwellings. As consequence, measures more effective if applied neighborhood level during winter, since it is critical time preventing compensatory population responses infestations.
