SUMMARY:

The ecological conditions generated by man in the urbanization process favor the synanthropic fauna that, using the resources of these areas, interact with human populations causing significant environmental, economic and public health damage. Although we noticed the coexistence of rats (Rattus spp.) and opossums (Didelphis spp.) in the urban environment, we do not know which variables regulate this phenomenon, how these animals compete and how this competition affects their respective distributions in these places. Here we aim to characterize the co-occurrence of rats and opossums, as well as their associated environmental factors in urban slums. The study was carried out over 2 seasonal periods in 2018, where we sampled 160 points distributed in 4 low-income communities in Salvador. There were 130 capture events of Rattus spp. and 203 of Didelphis spp., with a sampling effort of 1687 traps/night. We observed 24 co-occurrence events along the samplings. Using mixed generalized linear models and a multi-model approach, we proposed environmental models for the presence of rats, possums and their co-occurrences in an urban environment. Finally, we identify environmental characteristics common to these events and discuss how such implications can help build effective rodent control strategies and preserve synanthropic native species.
