  1. DISTRIBUTION OF ENDEMIC MAMMALS IN THE PERUVIAN YUNGAS Heidi Quintana & Victor Pacheco MUSEO DE HISTORIA NATURAL UNIVERSIDAD NACIONAL MAYOR DE SAN MARCOS LIMA - PERU

  2. PERU The territory of Peru covers 1,285,256 km². It neighbors Ecuador and Colombia to the north, Brazil to the east, Bolivia to the southeast, Chile to the south, and the Pacific Ocean to the west.

  3. PERUVIAN YUNGAS Elevation: 800 – 3600 m Extension: 15 000 000 ha Characteristics: The complex geology of the Andes has generated a landscape rich in biodiversity, endemism and unique ecosystems

  4. MAMMALS

  5. Endemism by Orders

  6. METHODS

  7. Endemic Species TYPE A TYPE B TYPE C 7

  8. Habitat-Geographic Barriers LANDSCAPE ECOLOGICAL FACTORS Endemic Species Species Data RECORDS Tools

  9. Polygons elaboration Compilation of Species Information (literature, museum records & observations) Polygons = Probable Distribution Create DataBase

  10. TYPE A: POLYGONS • Polygon around the species records • Arc View 3

  11. TYPE B: DEDUCTIVE MODEL • Species records • Altitudinal ranges – Digital Elevation Model (DEM) • North and South limits • Arc View 3

  12. TYPE C: INDUCTIVE MODEL • Environmental variables layer • Elevation • MODIS • Arc View 3 Maxent (a statistical mechanics approach)

  13. VARIABLES

  14. RESULTS

  15. Distribution along the Yungas DEPRESION DE HUANCABAMBA DEPARTMENTS LIMITS Akodon aerosus

  16. Distribution centered in the North DEPRESION DE HUANCABAMBA HUALLAGA RIVER Akodon orophilus

  17. Central Distribution PERENE RIVER INAMBARI RIVER Oecomys phaeotis

  18. Distribution centered in the South INAMBARI RIVER DEPARTMENT LIMIT Akodon kofordi

  19. Punctual Distribution Sturnira nana

  20. Exceptions: TAMBO RIVER DEPARTMENT LIMIT Carollia manu

  21. Gracilinanus aceramarcae

  22. Gracilinanus aceramarcae

  23. Cordillera occidental de Vilcabamba • Norwest of Huánuco • Cordillera de Paucartambo Above Inambari River • Yungas Centrales de Bolivia PRIORITY AREAS DeductiveModel Inductive model

  24. CONCLUSIONS • The species distribution model allows us to minimize errors by collecting specimens nearer to the roads and rivers. • Identify the remote natural areas in which it is likely that a species is located, based on the characteristics that they share with previously sampled sites. • The polygons around the points don’t provide the necessary precision for regional conservation in Peru.
