My dissertation aims to contribute to the knowledge of Andean bears in Peru. The Andean bear (Tremarctos ornatus) is the sole bear species in south America. The lack of knowledge on different aspects of Andean bear ecology, biogeography, and abundance patterns hinders current conservation efforts for the species. I compiled Andean bear occurrence records in Peru with collaboration from many colleagues and created an open-access database at the GBIF data repository. Next, I modeled the distribution of Andean bear within Peru and compared estimates including and excluding unpublished records. I found that models combining published and unpublished records …
